GHG emissions from the top 10 countries with the highest emissions accounted for almost two thirds of the global total. Since 2006, China has been emitting more CO 2 than any other country. [8] [9] [10] However, the main disadvantage of measuring total national emissions is that it does not take population size into account.
The following table lists the 1970, 1990, 2000, 2010, 2020, 2021, 2022 and 2023 annual per capita GHG [n 1] emissions estimates (in metric tons of CO 2 equivalent per year). The data include carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) from all sources, including agriculture and land use change. They are measured in carbon ...
Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison. Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all higher than ever before. [6] Electricity generation, heat and transport are major emitters; overall energy is responsible for around 73% of emissions. [7]

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]. 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 Global Nitrous Oxide Assessment (N2O) report is similar to the 2021 Global Methane Assessment, which showed that human-caused methane emissions can be reduced by up to 45% this decade and laid ...
A 2010 report estimated that sustainable use of biochar could reduce the global net emissions of carbon dioxide (CO 2), methane, and nitrous oxide by up to 1.8 billion tonnes carbon dioxide equivalent (CO 2 e) per year (compared to the about 50 billion tonnes emitted in 2021), without endangering food security, habitats, or soil conservation. [51]
The following table lists the annual CO 2 emissions estimates (in kilotons of CO 2 per year) for the year 2023, as well as the change from the year 2000. [4] The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry.
