Emissions of carbon dioxide, a greenhouse gas, per capita by country.

Greenhouse gas emissions by Australia totalled 533 million tonnes CO2-equivalent based on greenhouse gas national inventory report data for 2019; representing per capita CO2e emissions of 21 tons, [2] three times the global average. Coal was responsible for 30% of emissions. The national Greenhouse Gas Inventory estimates for the year to March 2021 were 494.2 million tonnes, which is 27.8 million tonnes, or 5.3%, lower than the previous year. It is 20.8% lower than in 2005 (the baseline year for the Paris Agreement). According to the government, the result reflects the decrease in transport emissions due to COVID-19 pandemic restrictions, reduced fugitive emissions, and reductions in emissions from electricity; however, there were increased greenhouse gas emissions from the land and agriculture sectors. [3]

Australia uses principally coal power for electricity, accounting for 66% of grid-connected electricity generation in 2020, [4] but this is rapidly decreasing with a growing share of renewables making up the energy supply mix, and most existing coal-fired power station scheduled to cease operation between 2022 and 2048. [5] Emissions by the country have started to fall and are expected to continue to fall in coming years as more renewable projects come online. [6]

Climate Action Tracker rates Australia's overall commitment to emissions reduction as "highly insufficient". Policies and action as well as the domestic target are both "insufficient", fair share target is "highly insufficient", and climate finance is "critically insufficient". This is because the Australian government has continued to invest in natural gas projects, refused to increase its 2030 domestic emissions target, and is not on track to meet its current target. [7]

Climate change in Australia is caused by greenhouse gas emissions, and the country is generally becoming hotter, and more prone to extreme heat, bushfires, droughts, floods and longer fire seasons because of climate change. [8]

Contribution

Total contributions

The Australian government calculates that Australia's net emissions (including Land use, land-use change, and forestry) for the 12-month period to September 2020 were 510.10 million tonnes CO2-equivalent. The sectoral contributions based on the IPCC Fifth Assessment Report metrics were as follows: electricity 170.36Mt, 33.4%; stationary energy (excluding electricity) 101.83Mt, 20.%; transport 89.83Mt, 17.6%; agriculture 72.04Mt, 14.1%; fugitive emissions 51.23Mt, 10.0%; industrial processes 30.29Mt, 5.9%; waste 13.28Mt, 2.6%, and LULUCF -18.76Mt, -3.7% (due to carbon sequestration). [9]

In 2017, the electricity sector emissions totaled 190 million tons, of which 20 million tons was for primary industry, 49 million tons for manufacturing (which might include aluminum smelting), 51 million tons Commercial, Construction and Transport, and 33 million tons Residential. [10]

The Australian National Greenhouse Gas Inventory (NGGI) indicated in 2006 that the energy sector accounts for 69 per cent of Australia's emissions, agriculture 16 per cent and LULUCF six per cent. Since 1990, however, emissions from the energy sector have increased 35 per cent (stationary energy up 43% and transport up 23%). By comparison, emissions from LULUCF have fallen by 73%. [11] However, questions have been raised about the veracity of the estimates of emissions from the LULUCF sector because of discrepancies between the Australian Federal and Queensland Governments’ land clearing data. Data published by the Statewide Landcover and Trees Study (SLATS) in Queensland, for example, show that the total amount of land clearing in Queensland identified under SLATS between 1989/90 and 2000/01 is approximately 50 per cent higher than the amount estimated by the Australian Federal Government’s National Carbon Accounting System (NCAS) between 1990 and 2001. [12]

Cumulative historical contribution

The World Resources Institute estimates that Australia was responsible for 1.1% of all CO2 emissions between 1850 and 2002. [13] Consolidated historical data measures Australia's total fossil fuels and cement production emissions (excluding LULUCF) at 18.18 billion tons out of the world's 1.65 trillion tons, or 1.10%. However noting that Australia has significant negative emissions from LULUCF relative to other countries, it is likely the net cumulative contribution proportion of Australia is much lower. [14] [ failed verification ]

Projected contribution

According to the no-mitigation scenario in the Garnaut Climate Change Review, Australia's share of world emissions, at 1.5% in 2005, declines to 1.1% by 2030, and to 1% by 2100. [15]

According to the polluter pays principle, the polluter has ecological and financial responsibility for the climate change consequences. The climate change is caused cumulatively and today's emissions will have effect for decades forward.

The CO2 emissions per capita was 15.22-15.37 tonnes in 2020, which made Australia the 11th largest CO2 emissions per capita just ahead of the United Arab Emirates and United States.(Citation 15 does not match new data) [17]

Emission sources

Some of the reasons for Australia's high levels of emissions include:

Production and export of carbon products

Australian emissions are monitored on a production rather than a consumption basis. This means that the emissions from the manufacture of goods imported into and consumed within Australia, for example many motor vehicles, are allocated to the country of manufacture. Similarly, Australia produces aluminium for export, which emits carbon dioxide during refining. [20] While the aluminium is mainly consumed overseas, the emissions of its production are allocated to Australia.

Coal

In 2018 Australia was the world's 2nd largest exporter of coal. [21] Australia is the world's largest exporter of metallurgical coal accounting for 55% of the world's supply in 2019. [22]

LNG

Australia became the world's largest exporter of liquefied natural gas in 2020. [23] [24]

Mitigation (technology aspects)

Mitigation of global warming involves taking actions to reduce greenhouse gas emissions and to enhance sinks aimed at reducing the extent of global warming. This is in distinction to adaptation to global warming, which involves taking action to minimize the effects of global warming. Scientific consensus on global warming, together with the precautionary principle and the fear of non-linear climate transitions, is leading to increased effort to develop new technologies and sciences and carefully manage others in an attempt to mitigate global warming.

In order to make a significant change, coal from Australia needs to be replaced with alternatives. [25]

Carbon capture and storage in Australia has been put forward as a solution for production of clean hydrogen from natural gas. [26] Following the introduction of government mandatory renewable energy targets, more opportunities have opened up for renewable energy technologies such as wind power, photovoltaics, and solar thermal technologies. Accelerating deployment of these technologies provides opportunities for mitigating greenhouse gases. [27]

A carbon price was introduced in 2012 by the government of Julia Gillard with the purpose of reducing Australia's carbon emissions. It required large businesses (defined as those with annual carbon dioxide equivalent emissions over 25,000 tonnes annually) to pay a price for emissions permits. The tax was scrapped by the Abbott government in 2014 in what was a widely criticized and highly publicized move.

Coal

Coal is the most polluting of all fossil fuels, and the single greatest threat to the climate. [28] Every stage of coal use brings substantial environmental damage. [29] Phasing out fossil fuel energy is one of the most important elements to climate change mitigation. [30] Today coal supplies over one third of the Australia's energy. [31] Brown coal is by far the most polluting, and is currently used in Victoria. [32] In order to have significant effects on greenhouse gas emissions, there needs to be a replacement of coal with alternatives. [33]

Reduction in the mining, use and export of coal is favored by environmental groups such as Greenpeace. Almost all of the coal emissions were emitted by coal fired power stations. Coal was responsible for 30% (164 million tonnes) of Australia's greenhouse gas emissions, not counting methane and export coal, based on 2019 GHG inventory. [34]

Two forms of coal are mined in Australia, depending on the region: high quality black coal and lower quality brown coal. Black coal is mainly found in Queensland and New South Wales, and is used for both domestic power generation and for export overseas. It is normally mined underground before being transported to power stations, or export shipping terminals. Brown coal is mainly found in Victoria and South Australia, and is of lower quality due a higher ash and water content. Today there are three open cut brown coal mines in Victoria used for baseload power generation.

Carbon capture and storage

The Rudd-Gillard government stated support for research into carbon capture and storage CCS as a possible solution to rising greenhouse gas emissions. [35] CCS is an integrated process, made up of three distinct parts: carbon capture, transport, and storage (including measurement, monitoring and verification). [28] Capture technology aims to produce a concentrated stream of CO2 that can be compressed, transported, and stored. Transport of captured CO2 to storage locations is most likely to be via pipeline. Storage of the captured carbon is the final part of the process. The vast majority of CO2 storage is expected to occur in geological sites on land, or below the seabed.

However, according to the Greenpeace False Hope Report, CCS cannot deliver in time to avoid a dangerous increase in world temperatures.

The Report also states that CCS wastes energy, and uses between 10 and 40% of the energy produced by a power station. [36] It also asserts that CCS is expensive, potentially doubling plant costs, and is very risky, as permanent storage cannot be guaranteed.

Nuclear energy

Australia has approximately 40% of the world's uranium deposits, and is the world's third largest producer of uranium. [37] Life-cycle greenhouse-gas emissions from nuclear power are low.

The only nuclear reactor in Australia is currently operated by ANSTO in the Sydney suburb of Lucas Heights. The main argument against building more is that the cost of electricity from new nuclear is more expensive than new solar power. [38] Other perceived problems include that enriched uranium can also be used as a nuclear weapon, prompting security issues such as nuclear proliferation. Also, nuclear waste requires extensive waste management because it can remain radioactive for centuries.

Renewable energy

Renewable energy technologies currently contribute about 6.2% of Australia's total energy supply and 21.3% of Australia's electricity supply, with hydro-electricity the largest single contributor and wind power a close second. [39] Initiatives are also being taken with ethanol fuel and geothermal energy exploration. [40]

Renewable energy targets

Vast solar potential is little used except on rooftops

Moving towards long-term mitigation policies is a requirement of government, and the Australian energy sectors remains a central area in national emissions. The International Energy Agency (IEA) reviewed the Australian energy sectors policies in 2018, [43] the findings identified needed improvements to the country's emissions reduction targets, and further the energy sectors resilience. The IEA identified needed improvements in government leadership by establishing a well-defined long-term integrated energy policy and climate toolkit for policy development and deployment.

The Australian Government has announced a mandatory renewable energy target (MRET) to ensure that renewable energy obtains a 20% share of electricity supply in Australia by 2020. To ensure this, the government has committed that the MRET will increase from 9,500 gigawatt-hours to 45,000 gigawatt-hours by 2020. After 2020 the proposed ETS and improved efficiencies from innovation and in manufacture are expected to allow the MRET to be phased out by 2030. [44]

Following the introduction of government Mandatory Renewable Energy Targets, [45] [46] more opportunities have opened up for renewable energies such as wind power, photovoltaics, and solar thermal technologies. The deployment of these technologies provides opportunities for mitigating greenhouse gases.

Solar power

By 2020 installed solar power by country was more in each of Italy, Japan and Germany than Australia despite their lower potentials.

Wind power

Wind farms are highly compatible with agricultural and pastoral land use.

Bioenergy

Bioenergy is energy produced from biomass. Biomass is material produced by photosynthesis, or is an organic by-product from a waste stream. Thus it can be seen as stored solar energy. [29] In terms of reducing greenhouse gas emissions, biomass offers four different types of contribution:

  • liquid and gaseous biofuels can substitute for oil in transportation;
  • biomass can be used in place of many greenhouse intensive materials;
  • biomass can be converted to biochar, an organic char coal that greatly enhances the ability of soil to sequester carbon. [29]

Sustainable energy expert Mark Diesendorf suggests that bioenergy could produce 39% of Australia's electricity generation. [29] [ needs update ]

Solar heat and electricity

Solar heat and electricity together have the potential for supplying all of Australia's energy, whilst using less than 0.1% of land. [47] With suitable government policies, particularly at the state and local levels, solar hot water could cost-effectively provide the vast majority of hot water systems in Australia, and make considerable reductions in residential electricity consumption. [29] Solar electricity's potential scale of application is huge and its prospects for further substantial cost reductions are excellent. [48]

Energy efficiency

The most important energy saving options include improved thermal insulation and building design, super efficient electrical machines and drives, and a reduction in energy consumption by vehicles used for goods and passenger traffic. Industrialized countries such as Australia, which currently use energy in the least efficient way, can reduce their consumption drastically without the loss of either housing comfort or amenity. [49] Increased energy efficiency of buildings had the support of the former leader of the federal opposition, Malcolm Turnbull. [50]

Energy storage

Hydrogen may become an important export. [51]

Biochar

Biochar has been promoted as a technique for mitigation of global warming. The former leader of the federal opposition, Malcolm Turnbull brought biochar into the political debate by announcing that burying agricultural waste was one of three under-invested areas that his mitigation strategy was committed to opening up. [50]

Publications and interest groups which track the fledgling Australian industry are divided over the suitability of biochar to the economy. Brian Toohey of The Australian Financial Review has said it is yet to be proven commercially viable. [52] Friends of the Earth Australia, one of the larger environmental lobby groups, is fundamentally opposed to biochar, calling it "part of a series of false solutions to climate change" which will be "based on large-scale industrial plantations and will lead to the acquisition of large tracts of land, furthering the erosion of indigenous peoples' and community rights while not adequately addressing the climate crisis". [53]

Green Left Weekly has published several editorials supporting the development of a large-scale biochar industry. [54]

Reforestation

Reforestation programs have adaptation and mitigation strategy overlap, [55] [56] and in 2014, the "20 million Trees Programme" was announced as a national strategy. The plan aimed to further native resilience against climatic changes by creating a self-sustaining tree-based ecosystem by planting 20 million native trees across Australia by 2020.[ needs update ] The Programme falls under the authority of the Australian Government's National Landcare Programme. [57] Increasing the coverage of flora range has the potential and capability to increase the habitability potential of areas threatened by climatic change and improve ecological communities that may be threatened or endangered. [58]

The Commonwealth government announced a plan in 2019 which would invest in Australia's forestry industry by planting 1 billion trees in nine forestry hubs throughout Australia by 2030. [59] Land management and biodiversity programs have emissions reduction benefits to both agricultural and environmental. [60] Advantages stem from the land's ability to adapt to climatic changes by helping to fight soil erosion and stabilize soil as well as providing shelter to native and agricultural animals. [61] AUD 1 billion will be invested the National Landcare program between 2018 and 2019 and 2022–23. [62]

Mitigation (policy aspects)

Coal policy is controversial

The economic impact of a 60% reduction of emissions by 2050 was modeled in 2006 in a study commissioned by the Australian Business Roundtable on Climate Change. [63] The World Resources Institute identifies policy uncertainty and over-reliance on international markets as the top threats to Australia's GHG mitigation. [64]

Domestic

After contributing to the development of, then signing but not ratifying the Kyoto Protocol, action to address climate change was coordinated through the Australian Greenhouse Office. The Australian Greenhouse Office released the National Greenhouse Strategy in 1998. The report recognized climate change was of global significance and that Australia had an international obligation to address the problem. In 2000 the Senate Environment, Communications, Information Technology and the Arts References Committee conducted an inquiry that produced The Heat is On: Australia's Greenhouse Future. [65]

One of Australia's first national attempt to reduce emissions was the voluntary-based initiative called the Greenhouse Challenge Program which began in 1995. [66] A collection of measures which focused on reducing the environmental impacts of the energy sector were released by Prime Minister John Howard on 20 November 1997 in a policy statement called Safeguarding Our Future: Australia's Response to Climate Change. [67] One measure was the establishment of the Australian Greenhouse Office, which was set up as the world's first dedicated greenhouse office in April 1998. [68]

Domestically, the Clean Energy Act 2011 addresses GHG with an emissions cap, carbon price, and subsidies. [64] Emissions by the electric sector are addressed by Renewable Energy targets at multiple scales, Australian Renewable Energy Agency (ARENA), Clean Energy Finance Corporation (CEFC), carbon capture and storage flagships, and feed-in tariffs on solar panels. Emissions by the industrial sector are addressed by the Energy Efficiency Opportunities (EEO) program. Emissions by the building sector are addressed by building codes, minimum energy performance standards, Commercial Building Disclosure program, state energy-saving obligations, and the National Energy Saving Initiative. Emissions by the transportation sector are addressed by reduced fuel tax credits and vehicle emissions performance standards. Emissions by the agricultural sector are addressed by the Carbon Farming Initiative and state land-clearing laws. Emissions by the land use sector are addressed by the Clean Energy Future Package, which consists of the Carbon Farming Futures program, Diversity Fund, Regional Natural Resources Management Planning for Climate Change Fund, Indigenous Carbon Farming Fund, Carbon Pollution Reduction Scheme (CPRS), and Carbon Farming Skills program. State energy saving schemes vary by state, with the Energy Saving Scheme (ESS) in North South Wales, Residential Energy Efficiency Scheme (REES) in South Australia, Energy Saver Incentive Scheme (ESI) in Victoria, and Energy Efficiency Improvement Scheme (EEIS) in Australian Capital Territory.

Carbon Trading and Emission Trading Scheme

In June 2007, former Australian Prime Minister, John Howard, announced that Australia would adopt a Carbon Trading Scheme by 2012. The scheme was expected to be the same as the counterpart in United States and European Union using carbon credits, where businesses must purchase a license in order to generate pollution.

The scheme received broad criticism from both the ALP and Greens. The ALP believed that the scheme was too weak as well as a bad political move by the government. The lack of clear target by the government for this scheme before the 2007 federal election produced a high degree of skepticism on the willingness of the government on mitigation of global warming in Australia.

In March 2008, the newly elected Labor government of Prime Minister Kevin Rudd announced that the Carbon Pollution Reduction Scheme (a cap-and-trade emissions trading system) would be introduced in 2010, however this scheme was initially delayed by a year to mid-2011, and subsequently delayed further until 2013. [69]

In April 2010, Kevin Rudd announced the delay the CPRS until after the commitment period of the Kyoto Protocol, which ends in 2012. Reasons given were the lack of bipartisan support for the CPRS and slow international progress on climate action for the delay.

The Federal Opposition strongly criticized the delay [70] as did community and grassroots action groups such as GetUp. [71]

Prime Ministerial Task Group

Carbon taxation

Another method of mitigation of global warming considered by the Australian Government is a carbon tax. This method would involve imposing an additional tax on the use of fossil fuels to generate energy. Compared to the CPRS and CTS/ETS, a carbon tax would set the cost for all carbon emissions, while the cap itself would be left unattended, allowing free market movements.

This tax would primarily be aimed to reduce the use of fossil fuels for energy generation, and also look to increase efficient energy use and increase demand for alternative energies. [72]

A carbon tax was introduced by the government of Julia Gillard on 1 July 2012. It requires businesses emitting over 25,000 tonnes of carbon dioxide equivalent emissions annually to purchase emissions permits, which initially cost A$23 for one tonne of CO2 equivalent. The tax was repealed by the Australian senate on 17 July 2014. The reason given for the repeal by Australia's 2014 prime minister Tony Abbot was that the tax cost jobs and increased energy prices. [73] Opponents to the repeal say that there has been an increase in Australian pollution since the tax's repeal. [74] Since the repeal there has been several calls to re-implement the tax from multiple public figures, including Woodside Petroleum CEO Peter Coleman. [75]

Pathways for climate change mitigation

Greenpeace energy revolution

Greenpeace calls for a complete energy revolution. There are some fundamental aspects to this revolution, aimed as changing the way that energy is produced, distributed and consumed. [30] The five principles of this revolution are:

  • implement renewable solutions, especially through decentralized energy systems;
  • respect the natural limits of the environment;
  • phase out dirty, unsustainable energy sources;
  • create greater equity in the use of resources;
  • decouple economic growth from the consumption of fossil fuels. [30]

Other goals of the energy revolution are:

  • renewable energy: 40% of electricity provided by renewable sources by 2020;
  • coal-fired power will be phased out entirely by 2030;
  • using electricity for the transport system and cutting consumption of fossil fuels through efficiency.

The energy revolution report also looks at policy suggestions for the Australian Government in regards to climate change. Policy suggestions of the report include:

  • legislate a greenhouse gas reduction target of greater than 40% below 1990 levels by 2020;
  • establish an emissions trading scheme that delivers a decrease of our emissions in line with legislated interim targets;
  • legislate a national target for 40% of electricity to be generated by renewable energy sources by 2020;
  • massively invest in the deployment of renewable energy and strongly regulate for energy efficiency measures;
  • establish an immediate moratorium on new coal-fired power stations and extensions to existing coal-fired power stations, and phase out existing coal-fired power stations in Australia by 2030;
  • set a target of 2% per year to reduce Australia's primary energy demand;
  • ensure transitional arrangements for coal dependent communities that might be affected by the transition to a clean energy economy;
  • redirect all public subsidies that encourage the use and production of fossil fuels towards implementing energy efficiency programs, deploying renewable energy and supporting the upgrading of public transport infrastructure;
  • develop a highly trained “green” workforce through investment in training programs and apprenticeships. [30]

Climate Code Red: The case for a sustainability emergency

Climate Code Red states that the key strategies for cutting greenhouse gas emissions to zero are resource efficiency backed up by the substitution of renewable energy for fossil fuel sources. [76] The report sites ultra-efficient technologies and synergies, and wind power as ways in which to tackle the climate change problem within Australia.

Climate Code Red also has an outline for a rapid transition to a safe-climate economy. This plan includes:

  • having the building capacity to plan, coordinate and allocate resources for high priority infrastructure projects and to invest sufficiently in the means to make safe-climate producer and consumer goods;
  • fostering research and innovation to produce, develop and scale up the necessary technologies, products and processes;
  • national building and industry energy efficiency programmes, including mandatory and enforceable minimum standards for domestic and commercial buildings, and the allocation of public resources to help householders, especially those with limited financial capacity, to reduce energy use;
  • the rapid construction of capacity across a range of renewable technologies at both a national and micro level to produce sufficient electricity to allow the closure of the fossil fuel-fired generating industry;
  • the conversion and expansion of Australia's car industry to manufacture zero-emission vehicles for public and private transport;
  • the renewal and electrification of national and regional train networks to provide the capacity to shift all long-distance freight from road and air to rail;

Further information: High-speed rail in Australia

  • providing safe-climate expertise, technologies, goods and services to less developed nations to support their transition to the post-carbon world;
  • adjustment and reskilling programmes for workers, communities and industries affected by the impacts of global warming and by the transition to the new economy. [76]

Garnaut climate change review

Green paper 2008

Climate Change Authority review

The Australian Climate Change Authority made recommendations to the Commonwealth government in 2016 to develop a toolkit of policies to guide the country into the future, [71] the focal point for the 'toolkit' is Australia's Paris Agreement obligations. [77] In 2017, the Commonwealth government commissioned an effectiveness' assessment of emissions reductions policies to meet its Paris Agreement obligations by 2030. [78] The results of the evaluation were to develop both adaptation and mitigation measure which would cover all sectors of the economy, under the Paris Agreement these measure fall under "ratchet mechanism". [79] To meet the 2030 Paris Agreements 2 °C limit of global median temperature rise a five-year review and adjustment cycle will commence beginning in 2023. [80]

Solutions

There are a number of ways to achieve the goals outlined above. This includes implementing clean, renewable solutions and decentralizing energy systems. [30] Existing technologies are available to use energy effectively and ecologically, including the use of solar, wind, and other renewable technologies, which have experienced double digit market growth globally in the last decade. [30]

A large section of the scientific community believe that one of the real solutions to avoiding dangerous climate change lies in renewable energy and energy efficiency that can start protecting the climate today. Technically accessible renewable energy sources such as wind, wave, and solar, are capable of providing six times more energy than the world currently consumes. [28] As coal is one of the highest emitters of greenhouse gases, closing coal power stations is one of the most powerful tools for carbon emission reduction. [81]

The city of Melbourne is working with the wider Australian government to make Melbourne carbon neutral by the year 2050. The name of the plan is Melbourne Together for 1.5°C. The plan includes ways for Melbourne to reduce the impact of waste, and models for how to reduce transport and building emissions to zero. This is a continuation off of a plan created in 2003 to have Melbourne carbon neutral by 2020, but this did not succeed.

Federal Government action

Howard government

The Howard government was resistant to taking action to prevent global warming that would harm Australia's economy, a policy continued from the prior Keating government. [82] In 1996 in the lead up to the Kyoto treaty this slow going attitude caused conflict with the US and EU who at that time were proposing legally binding emissions targets as part of Kyoto. Australia was unwilling to accept stricter timeframes and emissions reductions targets, such as the 20% cut (from 1990 to 2005) proposed by smaller pacific island states, because of its carbon-intensive economy. [82] Increasingly, in the lead up to the Kyoto conference, the Howard government became internationally isolated on its climate change policy. With Australia's opposition to binding targets "figur[ing] prominently in the prime minister's [recent] discussions in Washington and London" as highlighted in a Cabinet memo. [82] In 1997 the Cabinet agreed to establish a climate change taskforce to strengthen its Kyoto bargaining position. [82] In 1998 the Australian Government, under Prime Minister John Howard, established the Australian Greenhouse Office, which was then the world's first government agency dedicated to cutting greenhouse gas emissions, [83] And, also in 1998, Australia signed but did not ratify the Kyoto protocols. [84]

The Australian Greenhouse Office put forward proposals for emissions reductions in 2000 (rejected in cabinet), 2003 (vetoed by Howard) and 2006 which was accepted by Howard and became the basis for his pre election emissions trading scheme proposal. [82]

Rudd government

In 2007, after the first Rudd government was sworn in, the new Department of Climate Change was established under the Prime Minister and Cabinet portfolio and entrusted with coordinating and leading climate policy. [84] The Kyoto protocol was ratified nine days after. [84] The 2009 budget committed the government to a 25% reduction by 2020 on 2000 levels if "the world agrees to an ambitious global deal to stabilise levels of CO2 equivalent at 450 parts per million or lower by mid-century". [84]

On 1 December 2009, Malcolm Turnbull the then opposition leader was unseated by Tony Abbot, voiding a speculated deal on an emissions trading scheme between the opposition and the government. [84] This happened a day before the second rejection of the Carbon Pollution Reduction Scheme bill by the Senate on 2 December 2009. On 2 February 2010, the Emissions Trading Scheme legislation was introduced for the third time, it was voted down again and the Liberal party unveiled its own climate mitigation legislation, the Direct Action Plan. [84]

On 27 April 2010, the Prime Minister Kevin Rudd announced that the Government has decided to delay the implementation of the Carbon Pollution Reduction Scheme (CPRS) until the end of the first commitment period of the Kyoto Protocol (ending in 2012). [85] The government cited the lack of bipartisan support for the CPRS and the withdrawal of support by the Greens, [86] [87] [88] [89] and slow international progress on climate action after the Copenhagen Summit, as the reasons for the decision. [90] The delay of the implementation of the CPRS was strongly criticised by the Federal Opposition under Abbott [91] and by community and grassroots action groups such as GetUp. [92]

Gillard (and second Rudd) government

To reduce Australia's carbon emissions, the government of Julia Gillard introduced a carbon tax on 1 July 2012, which required large businesses, defined as those emitting over 25,000 tons of [93] carbon dioxide equivalent annually, to purchase emissions permits. The Carbon Tax reduced Australia's carbon dioxide emissions, with coal generation down 11% since 2008–09. [46]

Abbot government

The subsequent Australian Government, elected in 2013 under then Prime Minister Tony Abbott was criticised for being "in complete denial about climate change". [94] Abbott became known for his anti-climate change positions as was evident in a number of policies adopted by his administration. In a global warming meeting held in the United Kingdom, he reportedly said that proponents of climate change are alarmists, underscoring a need for "evidence-based" policymaking. [95] The Abbott government repealed the carbon tax on 17 July 2014 in a heavily criticised move. [71] The renewable energy target (RET), launched in 2001, was also modified. [30]

Turnbull government

However, under the government of Malcolm Turnbull, Australia attended the 2015 United Nations Climate Change Conference and adopted the Paris Agreement, which includes a review of emission reduction targets every 5 years from 2020. [96]

Australia's Clean Energy Target (CET) came under threat in October 2017 from former Prime Minister Tony Abbott. This could lead to the Australian Labor Party withdrawing support from the Turnbull government's new energy policy. [78] [97]

Climate policy continues to be controversial. Following the repeal of the carbon price in the last parliament, the Emissions Reduction Fund (ERF) is now Australia's main mechanism to reduce greenhouse gas emissions. However, two-thirds of the ERF's allocated $2.5 billion funding has now been spent. The ERF, and other policies, will need further funding to achieve our climate targets. [98]

Morrison government

Under the Morrison government, Australia experienced some criticism as it plans to use a carbon accounting loophole from the expiring Kyoto Protocol agreement to fulfill its (already modest) Paris commitments. According to Climate Analytics, Australia pledged in Paris to cut its emissions between 26% and 28% below 2005 levels by 2030 but it is currently on track for a 7% cut. [99]

The Coalition government repeatedly claimed in 2019 that it turned around Australia's greenhouse gas emissions that it inherited from the Labor government. Scott Morrison, Angus Taylor and other senior Coalition figures repeated this claim. The Coalition actually inherited a strong position from the Labor government which had enacted the carbon tax. [100]

There are suggestions that disinformation is spread about the cause of Australia bushfires. [101]

On 1 November 2019, Scott Morrison outlined in a speech of mining delegates at the Queensland Resources Council that he planned to legislate to outlaw climate boycotts. [102] [103]

State government actions

Per person emissions vary considerably by state. [104]

Victoria

The state of Victoria, in particular, has been proactive in pursuing reductions in GHG through a range of initiatives. In 1989 it produced the first state climate change strategy, "The Greenhouse Challenge". Other states have also taken a more proactive stance than the federal government. One such initiative undertaken by the Victorian Government is the 2002 Greenhouse Challenge for Energy Policy package, which aims to reduce Victorian emissions through a mandated renewable energy target. Initially, it aimed to have a 10 per cent share of Victoria's energy consumption being produced by renewable technologies by 2010, with 1000 MW of wind power under construction by 2006. The government legislated to ensure that by 2016 electricity retailers in Victoria purchase 10 per cent of their energy from renewables. This was ultimately overtaken by the national Renewable Energy Target (RET). By providing a market incentive for the development of renewables, the government helps foster the development of the renewable energy sector. A Green Paper and White Paper on Climate Change was produced in 2010, including funding for a number of programs. A Climate Change Act was passed including targets for 50% reduction in emissions. A recent review of this Act has recommended further changes.

The supreme court of Australia stopped a logging project in Victoria because it will be particularly destructive after the bushfires. The premier of Victoria Daniel Andrews announced that by 2030 logging in the state will be banned. [105]

South Australia

Former Premier Mike Rann (2002–2011) was Australia's first Climate Change Minister and passed legislation committing South Australia to renewable energy and emissions reduction targets. Announced in March 2006, this was the first legislation passed anywhere in Australia committed to cutting emissions. [106] By the end of 2011, 26% of South Australia's electricity generation derived from wind power, edging out coal-fired power for the first time. Although only 7.2% of Australia's population live in South Australia, in 2011, it had 54% of Australia's installed wind capacity. Following the introduction of solar feed-in tariff legislation South Australia also had the highest per-capita take-up of household rooftop photo-voltaic installations in Australia. In an educative program, the Rann government invested in installing rooftop solar arrays on the major public buildings including the Parliament, Museum, Adelaide Airport, Adelaide Showgrounds pavilion and public schools. About 31% of South Australia's total power is derived from renewables. In the five years to the end of 2011, South Australia experienced a 15% drop in emissions, despite strong employment and economic growth during this period. [107]

In 2010, the Solar Art Prize was created by Pip Fletcher, and has run annually since, inviting artists from South Australia to reflect subjects of climate change and environmentalism in their work. Some winning artists receive renewable energy service prizes which can be redeemed as solar panels, solar hot water or battery storage systems.

<span class="mw-page-title-main">Sustainable energy</span> Energy that responsibly meets social, economic, and environmental needs

Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Most definitions of sustainable energy include considerations of environmental aspects such as greenhouse gas emissions and social and economic aspects such as energy poverty. Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources. However, some renewable energy projects, such as the clearing of forests to produce biofuels, can cause severe environmental damage.

<span class="mw-page-title-main">Climate change mitigation</span> Actions to reduce net greenhouse gas emissions to limit climate change

Climate change mitigation is action to limit the greenhouse gases in the atmosphere that cause climate change. Greenhouse gas emissions are primarily caused by people burning fossil fuels such as coal, oil, and natural gas. Phasing out fossil fuel use can happen by conserving energy and replacing fossil fuels with clean energy sources such as wind, hydro, solar, and nuclear power. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Governments have pledged to reduce greenhouse gas emissions, but actions to date are insufficient to avoid dangerous levels of climate change.

<span class="mw-page-title-main">Energy in the United Kingdom</span> Overview of the energy use of the United Kingdom

Energy in the United Kingdom came mostly from fossil fuels in 2021. Total energy consumption in the United Kingdom was 142.0 million tonnes of oil equivalent in 2019. In 2014, the UK had an energy consumption per capita of 2.78 tonnes of oil equivalent compared to a world average of 1.92 tonnes of oil equivalent. Demand for electricity in 2014 was 34.42 GW on average coming from a total electricity generation of 335.0 TWh.

<span class="mw-page-title-main">Energy policy of the United Kingdom</span>

The energy policy of the United Kingdom refers to the United Kingdom's efforts towards reducing energy intensity, reducing energy poverty, and maintaining energy supply reliability. The United Kingdom has had success in this, though energy intensity remains high. There is an ambitious goal to reduce carbon dioxide emissions in future years, but it is unclear whether the programmes in place are sufficient to achieve this objective. Regarding energy self-sufficiency, UK policy does not address this issue, other than to concede historic energy security is currently ceasing to exist.

<span class="mw-page-title-main">Energy policy of the European Union</span> Legislation in the area of energetics in the European Union

The energy policy of the European Union focuses on energy security, sustainability, and integrating the energy markets of member states. An increasingly important part of it is climate policy. A key energy policy adopted in 2009 is the 20/20/20 objectives, binding for all EU Member States. The target involved increasing the share of renewable energy in its final energy use to 20%, reduce greenhouse gases by 20% and increase energy efficiency by 20%. After this target was met, new targets for 2030 were set at a 55% reduction of greenhouse gas emissions by 2030 as part of the European Green Deal. After the Russian invasion of Ukraine, the EU's energy policy turned more towards energy security in their REPowerEU policy package, which boosts both renewable deployment and fossil fuel infrastructure for alternative suppliers.

<span class="mw-page-title-main">Energy policy of Australia</span> Overview of the energy policy of Australia

The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of government in Australia, although only the State and Federal levels determine policy for primary industries such as coal. Federal policies for energy in Australia continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production. Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.

<span class="mw-page-title-main">Renewable energy in Australia</span>

Renewable energy in Australia is mainly based on biomass, solar, wind, and hydro generation. Over a third of electricity is generated from renewables, and is increasing, with a target to phase out coal power before 2040. Wind energy and rooftop solar have particularly grown since 2010. The growth has been stimulated by government energy policy in order to limit the rate of climate change in Australia that has been brought about by the use of fossil fuels. Pros and cons of various types of renewable energy are being investigated, and more recently there have been trials of green hydrogen and wave power.

<span class="mw-page-title-main">Greenhouse gas emissions by the United States</span> Climate changing gases from the North American country

The United States produced 5.2 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2020, the second largest in the world after greenhouse gas emissions by China and among the countries with the highest greenhouse gas emissions per person. In 2019 China is estimated to have emitted 27% of world GHG, followed by the United States with 11%, then India with 6.6%. In total the United States has emitted a quarter of world GHG, more than any other country. Annual emissions are over 15 tons per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person. However, the IEA estimates that the richest decile in the US emits over 55 tonnes of CO2 per capita each year. Because coal-fired power stations are gradually shutting down, in the 2010s emissions from electricity generation fell to second place behind transportation which is now the largest single source. In 2020, 27% of the GHG emissions of the United States were from transportation, 25% from electricity, 24% from industry, 13% from commercial and residential buildings and 11% from agriculture. In 2021, the electric power sector was the second largest source of U.S. greenhouse gas emissions, accounting for 25% of the U.S. total. These greenhouse gas emissions are contributing to climate change in the United States, as well as worldwide.

<span class="mw-page-title-main">Carbon Pollution Reduction Scheme</span> Australian emissions trading scheme

The Carbon Pollution Reduction Scheme was a cap-and-trade emissions trading scheme for anthropogenic greenhouse gases proposed by the Rudd government, as part of its climate change policy, which had been due to commence in Australia in 2010. It marked a major change in the energy policy of Australia. The policy began to be formulated in April 2007, when the federal Labor Party was in Opposition and the six Labor-controlled states commissioned an independent review on energy policy, the Garnaut Climate Change Review, which published a number of reports. After Labor won the 2007 federal election and formed government, it published a Green Paper on climate change for discussion and comment. The Federal Treasury then modelled some of the financial and economic impacts of the proposed CPRS scheme.

<span class="mw-page-title-main">Energy policy of China</span> Energy sources used and produced by China

China is both the world's largest energy consumer and the largest industrial country, and ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese Government since the founding of the People's Republic of China in 1949. Since the country's industrialization in the 1960s, China is currently the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. On a per-capita basis, China was only the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer, and the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy, where the goals of China's industrial production dictate its energy demand managements.

<span class="mw-page-title-main">Greenhouse gas emissions by the United Kingdom</span> Overview of the greenhouse gas emissions by United Kingdom

In 2021, net greenhouse gas (GHG) emissions in the United Kingdom (UK) were 427 million tonnes (Mt) carbon dioxide equivalent, 80% of which was carbon dioxide itself. Emissions increased by 5% in 2021 with the easing of COVID-19 restrictions, primarily due to the extra road transport. The UK has over time emitted about 3% of the world total human caused CO2, with a current rate under 1%, although the population is less than 1%.

A carbon pricing scheme in Australia was introduced by the Gillard Labor minority government in 2011 as the Clean Energy Act 2011 which came into effect on 1 July 2012. Emissions from companies subject to the scheme dropped 7% upon its introduction. As a result of being in place for such a short time, and because the then Opposition leader Tony Abbott indicated he intended to repeal "the carbon tax", regulated organizations responded rather weakly, with very few investments in emissions reductions being made. The scheme was repealed on 17 July 2014, backdated to 1 July 2014. In its place the Abbott government set up the Emission Reduction Fund in December 2014. Emissions thereafter resumed their growth evident before the tax.

After coal and oil the third most polluting fuel is fossil gas; which is burnt in Turkey's gas-fired power stations, homes and workplaces. Much methane is belched by livestock; cows alone produce half of the greenhouse gas from agriculture in Turkey.

<span class="mw-page-title-main">Greenhouse gas emissions by China</span> Emissions of gases harmful to the climate from China

China's greenhouse gas emissions are the largest of any country in the world both in production and consumption terms, and stem mainly from coal burning, including coal power, coal mining, and blast furnaces producing iron and steel. When measuring production-based emissions, China emitted over 14 gigatonnes (Gt) CO2eq of greenhouse gases in 2019, 27% of the world total. When measuring in consumption-based terms, which adds emissions associated with imported goods and extracts those associated with exported goods, China accounts for 13 gigatonnes (Gt) or 25% of global emissions.
