List of locations and entities by greenhouse gas emissions

Add article description

This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change. The relevant greenhouse gases are mainly: Carbon dioxide, Methane, Nitrous oxide and the fluorinated gases[2] bromofluorocarbon, chlorofluorocarbon, hydrochlorofluorocarbon,[3] hydrofluorocarbon,[4] nitrogen trifluoride,[3] perfluorocarbons and sulfur hexafluoride[4]

Emissions attributed to specific power stations around the world, color-coded by type of fuel used at the station. Lower half focuses on Europe and Asia[1]

The extraction and subsequent use of fossil fuels coal, oil and natural gas,[5] as a fuel source, is the largest contributor to global warming.[6]

Carbon dioxide

During June of 2023, with 12705 million tonnes CO2e produced, China is the largest emitter; USA is second with 6001, India 3394, EU (which is 27 countries) 3383, Russia 2476, Japan 1166, Brazil 1057, Indonesia 1002, Iran 893, and Canada 736.[7]

Scope 1+3 emissions, cumulative of the years 1988 - 2015, from oil and gas extraction [8]

This heading uses data from [9] a climate accountability[10] report of Heede, van Der Vlugt and Griffin of the Carbon Disclosure Project.[9] While data of emissions "Direct operational" and indirectly caused from the companies surveyed were indicated by the CDP, requests for data which were ignored by companies and emissions resulting from the use of products originating with companies were included as estimates by the researchers.[9] The data used by the CDP scientists is a composite of quantities of emissions as described via the GHG Protocol Corporate Standard (GHGPCS): Scope 1 and Scope 3 emissions (not including Scope 2) - these three being all the possible Scope-emission types. 1 is direct emissions sources from a companies owned or possessed resources, 3 is indirect sources subsequential from production activities; these are divided by GHGPCS into types: upstream and downstream, and 15 categories.[11] Scope 3 emissions are thought to be approximately 90% of the total from any company and result from the combustion of coal, and, or, oil, and, or, gas during the conversion of these into energy i.e. as fuel; which is categorized as a downstream.[9] The relevant tables below have a ranking of 20 industrial greenhouse gas emitters from 1988 to 2015 from the Carbon Majors Database (CDP) [12] report,[9] a July 10, 2017 [13] dataset of GtCO2e.[8]

The table below shows the total combined (cumulative) emissions as a percentage of all emissions. Oil and gas production data was obtained from annual reports from company websites and the SEC (2016). For some state owned enterprises, data was sourced from the ‘Oil & Gas Journal’ (1986-2016) or is estimated from national statistics (EIA 2017, BP 2016, and OPEC 2016):

Scope 3

Scope 3 emissions are thought to be approximately 90% of the total from any company (Scope 1) and result from fuel combustion.[9]

Vehicle emissions
See also: Exhaust gas

Pickup trucks were found to produce the most emissions in a group of vehicles including SUVs and cars, in a survey reported January 2022.[16] Excluding pickup trucks, the most polluting car type surveyed 2017 is the 2011 - 2020 Jeep Grand Cherokee which creates 372 grams per kilometre from the exhaust pipe, the 2007 - 2014 Audi R8 creates 346, thirdly the Chevrolet Camaro 335, the tenth most polluting, the Porsche Macan creates 291.[17]

Home: cooking fuels and technologies

The World Health Organization considers that during 2018 approximately 3 billion people, which was more than 40% of the 2018 estimated global population, used polluting fuel sources in their residences.[18]

Largest sources Carbon Dioxide (Scope 1)

Largest point source (Scope 1)

This section details production sites at single locations where the most pollution exists or existed in the recent past.

During March 2020, Secunda CTL, owned by Sasol, a synthetic fuel[21] and chemicals from coal [22] plant in Secunda, South Africa, was the producer of the single most emissions, at 56.5 million tonnes of CO2 a year.[21] The Department of Forestry, Fisheries, and the Environment (DFFE) of the Government of South Africa determined Sasol has until 1 April 2025 to comply with the legal limits for emissions,[23][24] as described by the Air Quality Act 2004:Part 3; 12; Category 3.[25] Sasol's pledge to reduce it's emissions from the plant by 10% by 2030 was reported during November 2020,[26] during 2023 it was reported that this was amended to 30%.[27]

As of 2021 the gas-fired power plant which emits the most is the Taichung Power Station in Taiwan, with 34.19 million tonnes CO2.[28][19]

Methane

Sources of anthropogenic production are in the majority:

Carbon bomb projects (new extractions)

A carbon bomb, or climate bomb,[34] is any new extraction of hydrocarbons from underground whose potential greenhouse gas emissions exceed 1 billion tonnes of CO2 worldwide. In 2022, a study showed that there are 425 fossil fuel extraction projects (coal, oil and gas) with potential CO2 emissions of more than 1 billion tonnes worldwide. The potential emissions from these projects are twice the 1.5°C carbon budget of the Paris Agreement. According to these researchers, defusing carbon bombs should be a priority for climate change mitigation policy.[35]

According to the same study, the Global Energy Monitor and "Banking on Climate Chaos" associations, between 2016 and 2022, the main backers of these climate bombs are the American banks JPMorgan Chase, Citibank and Bank of America.[36]

Between 2020 and 2022, at least twenty new "climate bombs" went into operation, reveals an international journalistic investigation.[37][38][36] In this survey, France's TotalEnergies is cited as the second most responsible group for fossil megafields, with a presence at 23 major hydrocarbon extraction sites.[39] In November 2023, China's China Energy will lead the ranking and Saudi Aramco of Saudi Arabia will complete the podium.[40]
