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. [1] 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. [2] However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. [3] On a per-capita basis, China was only the world's 51st largest emitter of greenhouse gases in 2016. [4] China is also the world's largest renewable energy producer (see this article), [5] 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. [6]
Being a country that depends heavily on foreign petroleum import for both domestic consumption and as raw materials for light industry manufacturing, electrification is a huge component of the Chinese national energy policy. Details for the power sector are likely to be released winter 2021/22 for the 14th five-year plan, [7] and this is expected to determine whether the country builds more coal-fired power stations, and therefore whether global climate targets are likely to be met.

Between 1980 and 2000, China's emissions density (its ratio of carbon dioxide equivalent emissions to gross domestic product) declined sharply. [10] : 26 The country quadrupled its GDP while only doubling the energy it consumed. [10] : 26 No other country at a similar stage of industrial development has matched this achievement. [10] : 26
On June 19, 2007, the Netherlands Environmental Assessment Agency announced that a preliminary study had indicated that China's greenhouse gas emissions for 2006 had exceeded those of the United States for the first time. The agency calculated that China's CO2 emissions from fossil fuels increased by 9% in 2006, while those of the United States fell by 1.4%, compared to 2005. [11] The study used energy and cement production data from British Petroleum which they believed to be 'reasonably accurate', while warning that statistics for rapidly changing economies such as China are less reliable than data on OECD countries. [12]
The Initial National Communication on Climate Change of the People's Republic of China calculated that carbon dioxide emissions in 2004 had risen to approximately 5.05 billion metric tons, with total greenhouse gas emissions reaching about 6.1 billion metric tons carbon dioxide equivalent. [13]
In 2002, China ranked 2nd (after the United States) in the list of countries by carbon dioxide emissions, with emissions of 3.3 billion metric tons, representing 14.5% of the world total. [14] In 2006, China overtook the US, producing 8% more emissions than the US to become the world's largest emitter of CO2 emissions. [15] However per capita China was ranked 51st in CO2 emissions per capita in 2016, with emissions of 7.2 tonnes per person (compared to 15.5 tonnes per person in the United States). [4] In addition, it has been estimated that around a third of China's carbon emissions in 2005 were due to manufacturing exported goods. [16]
In the industrial sector, six industries – electricity generation, steel, non-ferrous metals, construction materials, oil processing and chemicals – account for nearly 70% of energy use. [17]
In the construction materials sector, China produced about 44% of the world's cement in 2006. [12] Cement production produces more carbon emissions than any other industrial process, accounting for around 4% of global carbon emissions. [12]
China has been taking action on climate change for some years, with the publication on June 4, 2007, of China's first National Action Plan on Climate Change, [1] and in that year China became the first developing country to publish a national strategy addressing global warming. [18] The plan did not include targets for carbon dioxide emission reductions, but it has been estimated that, if fully implemented, China's annual emissions of greenhouse gases would be reduced by 1.5 billion tons of carbon dioxide equivalent by 2010. [18] Other commentators, however, put the figure at 0.950 billion metric tons. [19]
The publication of the strategy was officially announced during a meeting of the State Council, which called on governments and all sectors of the economy to implement the plan, and for the launch of a public environmental protection awareness campaign. [20]
The National Action Plan includes increasing the proportion of electricity generation from renewable energy sources and from nuclear power, increasing the efficiency of coal-fired power stations, [21] the use of cogeneration, and the development of coal-bed and coal-mine methane. [19]
In 2007 China stated that the (now reversed) one-child policy prevented 300 million births, saving 1.3 billion tons of CO2 emissions based on average world per capita emissions of 4.2 tons at 2005 level. [22]
Beginning with the 11th, each of China's five year plans have sought to move China away from energy-intensive manufacturing and into high-value sectors and have highlighted the importance of low-carbon technology as a strategic emerging industry, particularly in the areas of wind and solar power. [10] : 26–27 The plan set a national energy intensity target. [10] : 54 of a 20% reduction. [23] : 167 It was identified as a "binding target" and focused on throughout the Plan's implementation. [23] : 167 Policymakers viewed emissions reductions and energy conservation as the highest priority environmental matters under the 11th Five-Year Plan. [23] : 136
Successful achievement of emissions and energy conservation targets[ which? ] in the 11th Five-Year Plan shaped policymaker's approach for the 12th Five-Year Plan, prompting expanded use of binding targets to capitalize on successes in these areas. [23] : 136
In January 2012, as part of its 12th Five-year Plan, China published a report 12th Five-year Plan on Greenhouse Emission Control (guofa [2011] No. 41), which establishes goals of reducing carbon intensity by 17% by 2015, compared with 2010 levels and raising energy consumption intensity by 16%, relative to GDP. [24] More demanding targets were set for the most developed regions and those with most heavy industry, including Guangdong, Shanghai, Jiangsu, Zhejiang and Tianjin. [24] China also planned to meet 11.4% of its primary energy requirements from non-fossil sources by 2015. [24]
The plan will also pilot the construction of a number of low-carbon Development Zones and low-carbon residential communities, which it hopes will result in a cluster effect among businesses and consumers. [24]
To facilitate carbon trading and to more broadly help assess emissions targets and meet the transparency requirements of the Paris Agreement, the Plan improved the system for greenhouse gas emissions monitoring. [10] : 55 This was the first time that carbon emissions trading had featured in one of China's Five-Year Plans. [25] : 80
The plan also provided for the development of an ultra-high-voltage (UHV) transmission corridor to increase the integration of renewable energy from the point of generation to its point of consumption. [10] : 39–41
In addition, the Government will in future include data on greenhouse emissions in its official statistics. [24]
In a separate development, on January 13, 2012, [26] the National Development and Reform Commission announced that the cities of Beijing, Tianjin, Shanghai, Chongqing and Shenzhen, and the provinces of Hubei and Guangdong would become the first to participate in a pilot carbon cap and trade scheme that would operate in a similar way to the European Union Emission Trading Scheme. [24] The development follows an unsuccessful experiment with voluntary carbon exchanges that was set up in 2009 in Beijing, Shanghai and Tianjin. [24]

Coal remains the foundation of the Chinese energy system, covering close to 70 percent of the country's primary energy needs and representing 80 percent of the fuel used in electricity generation. [28] China produces and consumes more coal than any other country. Analysis in 2016 shows that China's coal consumption appears to have peaked in 2014. [29] [30] According to Global Energy Monitor, China's government has limited the hours of 40% of coal-fired power stations built in 2019, due to overcapacity in electricity generation. [31]
In 2023, China accounted for about two-thirds of the global increase in coal capacity, commissioning 47.4 gigawatts (GW) of new coal plants. This level of expansion represents the largest annual increase in coal capacity initiated by any country since 2015. [32]
China's oil supply was 4,855 TWh in 2009 which represented 10% of the world's supply. [33]
Although China is still a major crude oil producer, it became an oil importer in the 1990s. China became dependent on imported oil for the first time in its history in 1993 due to demand rising faster than domestic production. [1] In 2002, annual crude petroleum production was 1,298,000,000 barrels, and annual crude petroleum consumption was 1,670,000,000 barrels. In 2006, it imported 145 million tons of crude oil, accounting for 47% of its total oil consumption. [34] [35] By 2014 China was importing approximately 7 mil. barrels of oil per day. Three state-owned oil companies – Sinopec, CNPC, and CNOOC – dominate its domestic market.
China announced on June 20, 2008, plans to raise petrol, diesel and aviation kerosene prices. This decision appeared to reflect a need to reduce the unsustainably high level of subsidies these fuels attract, given the global trend in the price of oil. [36]
Top oil producers were in 2010: Russia 502 Mt (13%), Saudi Arabia 471 Mt (12%), US 336 Mt (8%), Iran 227 Mt (6%), China 200 Mt (5%), Canada 159 Mt (4%), Mexico 144 Mt (4%), UAE 129 Mt (3%). The world oil production increased from 2005 to 2010 1.3% and from 2009 to 2010 3.4%. [37]
China's natural gas supply was 1,015 TWh in 2009 that was 3% of the world supply. [38]
CNPC, Sinopec, and CNOOC are all active in the upstream gas sector, as well as in LNG import, and in midstream pipelines. Branch pipelines and urban networks are run by city gas companies including China Gas Holdings, ENN Energy, Towngas China, Beijing Enterprises Holdings and Kunlun Energy.
China was top seventh in natural gas production in 2010. [37]
Issued by China's State Council in September 2013, China's Action Plan for the Prevention and Control of Air Pollution illustrates government desire to increase the share of natural gas in China's energy mix. [1] In May 2014 China signed a 30-year deal with Russia to deliver 38 billion cubic metres of natural gas each year. [39] The Power of Siberia pipeline is designed to reduce China's dependence on coal, which is more carbon intensive and causes more pollution than natural gas. [40] The proposed western gas route from Russia's West Siberian petroleum basin to North-Western China is known as Power of Siberia 2. [41]
In November 2021, U.S. producer Venture Global LNG signed a twenty-year contract with China's state-owned Sinopec to supply liquefied natural gas (LNG). [42] China's imports of U.S. natural gas would more than double. [43]
In 2013, China's total annual electricity output was 5.398 trillion kWh and the annual consumption was 5.380 trillion kWh with an installed capacity of 1247 GW (all the largest in the world). [45]
This is an increase from 2009, when China's total annual electricity output was 3.71465 trillion kWh, [46] and the annual consumption was 3.6430 trillion kWh (second largest in the world). [47] In the same year, the total installed electricity generating capacity was 874 GW. [48] China is undertaking substantial long-distance transmission projects with record breaking capacities, and has the goal of achieving an integrated nationwide grid in the period between 2015 and 2020. [49]
In 2015, China generated 73% of its electricity from coal-fired power stations, which has been dropping from a peak of 81% in 2007. [27]
In recent years, China has increased its use of coal power and continued to build new coal power plants. The National Energy Administration's early warning risk rating for coal plants approved the establishment of new power plants in 2020. China shut down roughly 7GW of power plants at the same time, continuing to decommission ageing coal-fired power reactors. [50]

In 2024, global coal-power capacity reached a record 2,130 gigawatts, with China initiating 70 gigawatts of new coal plants—nearly 20 times more than the rest of the world combined. This expansion led to a 2% increase in the world's coal fleet, primarily to enhance China's energy security. Despite a global shift away from coal, this rise underscores potential conflicts with China's climate goals. Additionally, coal capacity also grew in Indonesia and India, marking the first global increase outside China since 2019. [51]
China is the world's leading renewable energy producer, with an installed capacity of 152 GW. [5] China has been investing heavily in the renewable energy field in recent years. In 2007, the total renewable energy investment was US$12 billion, second only to Germany. [52] In 2012, China invested US$65.1 billion in clean energy (20% more than in 2011), fully 30% of the total investment by the G-20, including 25% (US$31.2 billion) of global solar energy investment, 37% percent (US$27.2 billion) of global wind energy investment, and 47% (US$6.3 billion) of global investment in "other renewable energy" (small hydro, geothermal, marine, and biomass); 23 GW of clean generation capacity was installed. [53] [ needs update ]
Approximately 7% of China's energy was from renewable sources in 2006, a figure targeted to rise to 10% by 2010 and to 16% by 2020. [19] The major renewable energy source in China is hydropower. Total hydro-electric output in China in 2009 was 615.64 TWh, constituting 16.6% of all electricity generated. The country already has the most hydro-electric capacity in the world, and the Three Gorges Dam is currently the largest hydro-electric power station in the world, with a total capacity of 22.5 GW. It has been in full operation since May 2012.[ needs update ]
China is the largest producer of wind turbines and solar panels. [54] [ needs update ]
In 2012, China had 15 nuclear power units with a total electric capacity of 11 GW and total output of 54.8 billion kWh, accounting for 1.9% country's total electricity output. This rose to 17 reactors in 2013. By 2016 the number of operating nuclear reactors was 32 with 22 under construction and other dozen to start construction this year. There are plans to increase nuclear power capacity and nuclear power percentage, bringing the total electricity output to 86 GW and 4% respectively by 2020. [55] Plans are to increase this to 200 GWe by 2030, and 400 GWe by 2050. China has set an end-of-the-century goal of 1500GWs of nuclear energy, most of this from fast reactors. China has 32 [56] reactors under construction, the highest number in the world.[ needs update ]

Following the completion of the similar Township Electrification Program in 2005, the Village Electrification Program plans to provide renewable electricity to 3.5 million households in 10,000 villages by 2010. This is to be followed by full rural electrification using renewable energy by 2015. [57]
Although a majority of the renewable energy in China is from hydropower, other renewable energy sources are in rapid development. In 2006, a total of 10 billion US dollars had been invested in renewable energy, second only to Germany. [58]
China is a major source of clean energy technology transfer to other developing countries. [10] : 4
In 2006, 16 million tons of corn were used to produce a first generation biofuel (ethanol). [59] However, because food prices in China rose sharply during 2007, China has decided to ban the further expansion of the corn ethanol industry.
On February 7, a spokesman for the State Forestry Administration announced that 130,000 square kilometres (50,000 sq mi) would be devoted to biofuel production. Under an agreement reached with PetroChina in January 2007, 400 square kilometres of Jatropha curcas is to be grown for biodiesel production. Local governments are also developing oilseed projects. There were concerns that such developments may lead to environmental damage. [60]
In 2018, The Telegraph reported that the biofuel industry was further on the rise. [61] There was[ when? ] also considerable interest in biofuels (for example biodiesel, green jet fuel) [62] [63] [64] which use waste material as the input source (second generation biofuel).
China has become the world's largest consumer of solar energy. [65] It is the largest producer of solar water heaters, accounting for 60 percent of the world's solar hot water heating capacity, and the total installed heaters is estimated at 30 million households. [66] Solar photovoltaic (solar PV) production in China is also in rapid development. In 2007, 0.82 GW of solar PV was produced, second only to Japan. [5]
China's Sixth Five-Year Plan (1981-1985) was the first to address government policy support for solar PV panel manufacturing. [10] : 34 Policy support for solar panel manufacturing has been a part of every Five-Year Plan since. [10] : 34
As part of the stimulus plan of "Golden Sun", announced by the government in 2009, several developments and projects became part of the milestones for the development of solar technology in China. These include the agreement signed by LDK for a 500MW solar project, a new thin film solar plant developed by Anwell Technologies in Henan province using its own proprietary solar technology and the solar power plant project in a desert, headed by First Solar and Ordos City. The effort to drive the renewable energy use in China was further assured after the speech by the Chinese President, given at the UN climate summit on 22 September 2009 in New York, pledging that China would plan to have 15% of its energy from renewable sources by 2019. China is using solar power in houses, buildings, and cars. [67] [68] [69]
Because solar works well as a distributed power source, recent[ when? ] Chinese policies have focused on increasing the prevalence of distributed solar energy and for developing systems so that electricity from solar energy can be used at its point of generation instead of being transmitted over long distances. [10] : 34
China's total wind power capacity reached 2.67 gigawatts (GW) in 2006 and 44.7 GW by 2010. [70] [71] This figure reached 281 GW in 2020, an increase of 71.6 GW on the previous year. [72]
Officials were warned that violating energy conservation and environmental protection laws would lead to criminal proceedings, while failure to achieve targets would be taken into account in the performance assessment of officials and business leaders. [17]
After achieving less than half the 4% reduction in energy intensity targeted for 2006, all companies and local and national government were asked to submit detailed plans for compliance before June 30, 2007. [73] [74]
During the first four years of the plan, energy intensity improved by 14.4%, but dropped sharply in the first quarter of 2010. In August 2010, China announced the closing of 2,087 steel mills, cement works and other energy-intensive factories by September 30, 2010. The factory closings were made more palatable by a labor shortage in much of China making it easier for workers to find other jobs. [75]
A State Council circular issued on June 3, 2007, restricts the temperature of air conditioning in public buildings to no lower than 26 °C in summer (78.8 °F), and of heating to no higher than 20 °C (68 °F) in winter. The sale of inefficient air conditioning units has also been outlawed. [76]
The Chinese results from the 1st Annual World Environment Review, published on June 5, 2007, revealed that, in a sample of 1024 people (50% male): [77]
Another survey published in August 2007 by China Youth Daily and the British Council sampled 2,500 Chinese people with an average age of 30.1. It showed that 80% of young Chinese are concerned about global warming. [78]
Renewable energy progress in the European Union (EU) is driven by the European Commission's 2023 revision of the Renewable Energy Directive, which raises the EU's binding renewable energy target for 2030 to at least 42.5%, up from the previous target of 32%. Effective since November 20, 2023, across all EU countries, this directive aligns with broader climate objectives, including reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Additionally, the Energy 2020 strategy exceeded its goals, with the EU achieving a 22.1% share of renewable energy in 2020, surpassing the 20% target.
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.
World energy resources are the estimated maximum capacity for energy production given all available resources on Earth. They can be divided by type into fossil fuel, nuclear fuel and renewable resources.
Renewable energy in Germany is mainly based on wind and biomass, plus solar and hydro. Germany had the world's largest photovoltaic installed capacity until 2014, and as of 2023 it has over 82 GW. It is also the world's third country by installed total wind power capacity, 64 GW in 2021 and second for offshore wind, with over 7 GW. Germany has been called "the world's first major renewable energy economy".
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.
Fossil fuel phase-out is the gradual reduction of the use and production of fossil fuels to zero, to reduce deaths and illness from air pollution, limit climate change, and strengthen energy independence. It is part of the ongoing renewable energy transition, but is being hindered by fossil fuel subsidies.
Renewable energy in Finland increased from 34% of the total final energy consumption (TFEC) in 2011 to 48% by the end of 2021, primarily driven by bioenergy (38%), hydroelectric power (6.1%), and wind energy (3.3%). In 2021, renewables covered 53% of heating and cooling, 39% of electricity generation, and 20% of the transport sector. By 2020, this growth positioned Finland as having the third highest share of renewables in TFEC among International Energy Agency (IEA) member countries.
China is the world's leader in electricity production from renewable energy sources, with over triple the generation of the second-ranking country, the United States. China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity, and is expected to contribute 43% of global renewable capacity growth. China's total renewable energy capacity exceeded 1,000 GW in 2021, accounting for 43.5 per cent of the country's total power generation capacity, 10.2 percentage points higher than in 2015. The country aims to have 80 per cent of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200 GW of solar and wind capacity by 2030. In 2023, it was reported that China was on track to reach 1,371 gigawatts of wind and solar by 2025, five years ahead of target due to new renewables installations breaking records. China's carbon emissions are now expected to decrease in 2024, years ahead of the target of peak emissions by 2030.
Since 2013, total primary energy consumption in India has been the third highest in the world after China and United States. India is the second-top coal consumer in the year 2017 after China. India ranks third in oil consumption with 22.1 crore tons in 2017 after United States and China. India is net energy importer to meet nearly 47% of its total primary energy in 2019.
Low-carbon electricity or low-carbon power is electricity produced with substantially lower greenhouse gas emissions over the entire lifecycle than power generation using fossil fuels. The energy transition to low-carbon power is one of the most important actions required to limit climate change.
Vietnam is a dynamic developing economy with a relatively high growth rate. The energy sector plays a key role in promoting the country's socio-economic development. Vietnam has a diverse energy fuel resource of various types such as coal, natural gas, petroleum, hydropower and renewables such as solar and wind energy. The country has recently been successful in renewable energy deployment, especially solar and wind power development. Coal has been the key power generation source since 2018. Coal accounted for about 30% of installed capacity and 47% of electricity generation in 2021 The high use of coal makes Vietnam an increasingly important emitter of carbon dioxide, contributing to climate change.
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, 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. 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.
Energy in Australia is the production in Australia of energy and electricity, for consumption or export. Energy policy of Australia describes the politics of Australia as it relates to energy.
In 2019, the total energy production in Indonesia is 450.79 Mtoe, with a total primary energy supply is 231.14 Mtoe and electricity final consumption is 263.32 TWh. Energy use in Indonesia has been long dominated by fossil resources. Once a major oil exporter in the world and joined OPEC in 1962, the country has since become a net oil importer despite still joined OPEC until 2016, making it the only net oil importer member in the organization. Indonesia is also the fourth-largest biggest coal producer and one of the biggest coal exporter in the world, with 24,910 million tons of proven coal reserves as of 2016, making it the 11th country with the most coal reserves in the world. In addition, Indonesia has abundant renewable energy potential, reaching almost 417,8 gigawatt (GW) which consisted of solar, wind, hydro, geothermal energy, ocean current, and bioenergy, although only 2,5% have been utilized. Furthermore, Indonesia along with Malaysia, have two-thirds of ASEAN's gas reserves with total annual gas production of more than 200 billion cubic meters in 2016.
Energy in Sweden describes energy and electricity production, consumption and import in Sweden. Electricity sector in Sweden is the main article of electricity in Sweden. The Swedish climate bill of February 2017 aims to make Sweden carbon neutral by 2045. The Swedish target is to decline emission of climate gases 63% from 1990 to 2030 and international transportation excluding foreign flights 70%. By 2014 just over half of the country's total final energy consumption in electricity, heating and cooling and transport combined was provided by renewables, the highest share amongst the then 28 EU member countries. About a third of Sweden's electricity is generated by nuclear power. In generating a year's worth of this energy, Swedes generate about 4 tonnes of CO2 emissions each. Since 2010, sustainability measures have reduced total emissions even as the population has increased.
Primary energy consumption in Spain in 2020 was mainly composed of renewable sources. The largest sources are petroleum (42.3%), natural gas (19.8%) and coal (11.6%). The remaining 26.3% is accounted for by nuclear energy (12%) and different renewable energy sources (14.3%). Domestic production of primary energy includes nuclear (44,8%), solar, wind and geothermal (22,4%), biomass and waste (21,1%), hydropower (7,2%) and fossil (4,5%).
Energy in Portugal describes energy and electricity production, consumption and import in Portugal. Energy policy of Portugal will describe the politics of Portugal related to energy more in detail. Electricity sector in Portugal is the main article of electricity in Portugal.
An energy transition is a major structural change to energy supply and consumption in an energy system. Currently, a transition to sustainable energy is underway to limit climate change. As much sustainable energy is renewable it is also known as the renewable energy transition. The current transition aims to reduce greenhouse gas emissions from energy quickly and sustainably, mostly by phasing-down fossil fuels and changing as many processes as possible to operate on low carbon electricity. A previous energy transition perhaps took place during the Industrial Revolution from 1760 onwards, from wood and other biomass to coal, followed by oil and later natural gas.
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.
World energy supply and consumption refers to the global supply of energy resources and its consumption. Throughout its lifecycle, global energy supplies have multiple different stages such as initial production, refinement activities, trade of energy resources, and final consumption of the energy.
