According to European Commission data, global greenhouse gas emissions in 2022 reached 53.79 gigatons of carbon dioxide equivalent (Gt CO2e).
This figure represents a 1.4% increase year-on-year, setting a new record high.
The greenhouse gas emissions recorded by the European Commission are a combination of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (F gases).
This data only includes emissions from the following sectors: power generation, transportation, energy combustion for industry, agriculture, fossil fuel exploitation (mining, production, and processing), industrial processes (such as cement production, metal processing, chemical products, etc.), energy combustion for non-industrial buildings, and the waste sector.
Greenhouse gas emissions from the forestry and land use, land-use change, and forestry (LULUCF) sector are not included.
In terms of source, greenhouse gas emissions globally last year originated mostly from the power generation sector.
The following details the volume of global greenhouse gas emissions in 2022 by sector, ordered from largest to smallest contributor:
* Power generation: 14.77 Gt CO2e (contributing 27.45% to total global greenhouse gas emissions)
* Transportation: 8.10 Gt CO2e (15.07%)
* Energy combustion for industry: 6.58 Gt CO2e (12.24%)
* Agriculture: 6.49 Gt CO2e (12.07%)
* Fossil fuel exploitation: 6.24 Gt CO2e (11.60%)
* Industrial processes: 5.04 Gt CO2e (9.37%)
* Energy combustion for non-industrial buildings: 3.81 Gt CO2e (7.08%)
* Waste: 2.75 Gt CO2e (5.12%)
According to the European Commission, six countries were most responsible for global greenhouse gas emissions in 2022: China, the United States, India, the European Union (combined 27 member states), Russia, and Brazil.
"Collectively, they account for 50.1% of the global population, 61.2% of the world's gross domestic product, 63.4% of total fossil fuel consumption, and generate 61.6% of total global greenhouse gas emissions," stated the European Commission in its report, *GHG Emissions of All World Countries 2023*.
