Emissions trading is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants. The concept is also known as cap and trade (CAT) or emissions trading scheme (ETS). Carbon emission trading for CO2 and other greenhouse gases has been introduced in China, the European Union and other countries as a key tool for climate change mitigation. Other schemes include sulfur dioxide and other pollutants.
A carbon tax is a tax levied on the carbon emissions required to produce goods and services. Carbon taxes are intended to make visible the "hidden" social costs of carbon emissions, which are otherwise felt only in indirect ways like more severe weather events. In this way, they are designed to reduce carbon dioxide (CO
2) emissions by increasing prices. This both decreases demand for such goods and services and incentivizes efforts to make them less carbon-intensive. In its simplest form, a carbon tax covers only CO2 emissions; however, they can also cover other greenhouse gases, such as methane or nitrous oxide, by calculating their global warming potential relative to CO2. When a hydrocarbon fuel such as coal, petroleum, or natural gas is burnt, much of its carbon is converted to CO
2. Greenhouse gas emissions cause climate change, which damages the environment and human health. This negative externality can be reduced by taxing carbon content at any point in the product cycle. Carbon taxes are thus a type of Pigovian tax.
The Department for Environment, Food and Rural Affairs (Defra) is the government department responsible for environmental protection, food production and standards, agriculture, fisheries and rural communities in the United Kingdom of Great Britain and Northern Ireland. Concordats set out agreed frameworks for co operation, between it and the Scottish Government, Welsh Government and Northern Ireland Executive, which have devolved responsibilities for these matters in their respective nations.
The United Kingdom's Climate Change Programme was launched in November 2000 by the British government in response to its commitment agreed at the 1992 United Nations Conference on Environment and Development (UNCED). The 2000 programme was updated in March 2006 following a review launched in September 2004.
The Climate Change Levy (CCL) is a tax on energy delivered to non-domestic users in the United Kingdom.
In animal husbandry, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year. An animal unit is the equivalent of 1,000 pounds of "live" animal weight. A thousand animal units equates to 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than 55 pounds (25 kg), 10,000 pigs weighing under 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg laying hens or pullets.
Various energy conservation measures are taken in the United Kingdom.
The current energy policy of the United Kingdom is the responsibility of the Department for Business, Energy and Industrial Strategy (BEIS), after the Department of Energy and Climate Change was merged with the Department for Business, Innovation and Skills in 2016. Energy markets are also regulated by the Office of Gas and Electricity Markets (Ofgem).
The Fossil Fuel Levy (FFL) is a levy paid by suppliers of electricity from non-renewable energy sources in the United Kingdom. The costs are shared by the suppliers and consumers, as a proportion of the cost is passed on to consumers in the cost of the electricity supplied. The Fossil Fuel Levy was imposed to fund the Non-Fossil Fuel Obligation.
The Code for Sustainable Homes was an environmental assessment method for rating and certifying the performance of new homes in United Kingdom. First introduced in 2006, it is a national standard for use in the design and construction of new homes with a view to encouraging continuous improvement in sustainable home building. In 2015 the Government in England withdrew it, consolidating some standards into Building Regulations.
The United States produced 6.6 billion metric tons of carbon dioxide equivalent greenhouse gas (GHG) emissions in 2019, 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 tonnes per person and, amongst the top eight emitters, is the highest country by greenhouse gas emissions per person. 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 2019, 29% of the GHG emissions of the United States were from transportation, 25% from electricity, 23% from industry, 13% from commercial and residential buildings and 10% from agriculture. These greenhouse gas emissions are contributing to climate change in the United States as well as worldwide.
The CRC Energy Efficiency Scheme was a mandatory carbon emissions reduction scheme in the United Kingdom which applied to large energy-intensive organisations in the public and private sectors. It was estimated that the scheme would reduce carbon emissions by 1.2 million tonnes of carbon per year by 2020. In an effort to avoid dangerous climate change, the British Government first committed to cutting UK carbon emissions by 60% by 2050, and in October 2008 increased this commitment to 80%. The scheme has also been credited with driving up demand for energy-efficient goods and services.
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.
Emission trading (ETS) for carbon dioxide (CO2) and other greenhouse gases (GHG) is a form of carbon pricing. It is an approach to limit climate change by creating a market with limited allowances for emissions. This can lower competitiveness of fossil fuels and accelerate investments into low carbon sources of energy such as wind power and photovoltaics. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
The economics of climate change mitigation is the part of the economics of climate change related to climate change mitigation, that is actions that are designed to limit the amount of long-term climate change. Mitigation may be achieved through the reduction of greenhouse gas (GHG) emissions and the enhancement of sinks that absorb GHGs, for example forests.
The reduction of carbon emissions, along with other greenhouse gases (GHGs), has become a vitally important task of international, national and local actors. If we understand governance as the creation of “conditions for ordered rule and collective action” then, given the fact that the reduction of carbon emissions will require concerted collective action, it follows that the governance of carbon will be of paramount concern. We have seen numerous international conferences over the past 20 years tasked with finding a way of facilitating this, and while international agreements have been infamously difficult to reach, action at the national level has been much more effective. In the UK, the Climate Change Act 2008 committed the government to meeting significant carbon reduction targets. In England, these carbon emissions are governed using numerous different instruments, which involve a variety of actors. While it has been argued by authors like Rhodes that there has been a “hollowing out” of the nation state, and that governments have lost their capabilities to govern to a variety of non-state actors and the European Union, the case of carbon governance in England actually runs counter to this. The government body responsible for the task, the Department of Energy and Climate Change (DECC), is the “main external dynamic” behind governing actions in this area, and “rather than hollowing out central co-ordination”. The department may rely on other bodies to deliver its desired outcomes, but it is still ultimately responsible for the imposition of the rules and regulations that “steer (carbon) governmental action at the national level”. It is therefore evident that carbon governance in England is hierarchical in nature, in that “legislative decisions and executive decisions” are the main dynamic behind carbon governance action. This does not deny the existence of a network of bodies around DECC who are part of the process, but they are supplementary actors who are steered by central decisions. This article focuses on carbon governance in England as the other countries of the UK all have devolved assemblies who are responsible for the governance of carbon emissions in their respective countries.
Hydraulic fracturing in the United Kingdom started in the late 1970s with fracturing of the conventional oil and gas fields near the North Sea. It has been used in about 200 British onshore oil and gas wells since the early 1980s. The technique did not attract attention until licences use were awarded for onshore shale gas exploration in 2008.
As of 2018, hydroelectric power stations in the United Kingdom accounted for 1.87 GW of installed electrical generating capacity, being 2.2% of the UK's total generating capacity and 4.2% of UK's renewable energy generating capacity. This includes four conventional hydroelectric power stations and run-of-river schemes for which annual electricity production is approximately 5,000 GWh, being about 1.3% of the UK's total electricity production. There are also pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.
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 organisations 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.
Green economy policies in Canada are policies that contribute to transitioning the Canadian economy to a more environmentally sustainable one. The green economy can be defined as an economy, "that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities." Aspects of a green economy would include stable growth in income and employment that is driven by private and public investment into policies and actions that reduce carbon emissions, pollution and prevent the loss of biodiversity.
