According to European Commission data, the volume of global greenhouse gas emissions in 2023 reached 52,962 million tonnes of carbon dioxide equivalent (Mt CO2eq).
China was the largest emitter of greenhouse gases, contributing 30.1% of total global emissions.
The next largest emitting countries were the United States, India, the European Union, Russia, and Brazil.
Indonesia ranked 7th with greenhouse gas emissions of 1,200 Mt CO2eq, equivalent to 2.3% of total global emissions.
Following were Japan, Iran, and Saudi Arabia, with emission amounts as shown in the graph.
Combined, these 10 countries accounted for approximately 70% of total global greenhouse gas emissions in 2023.
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).
The data only includes emissions from the electricity generation, transport, industrial energy combustion, agriculture, fossil fuel exploitation (mining, production, and processing), industrial processes (such as cement production, metal processing, chemical products, etc.), non-industrial building energy combustion, and waste sectors.
Greenhouse gas emissions from the forestry and land use, land-use change, and forestry (LULUCF) sector are not included.
