Greenhouse Gas Emissions By Country 2021

Emissions by CountryChinaThe United StatesIndiaRussiaJapanGermanySouth KoreaIranCanadaThe world’s countries produce varying amounts of greenhouse gases into the atmosphere. The overall emissions level in a country can be explained by the size of its population, its GDP, its energy mix, and more. In 2017, global carbon dioxide emissions from fuel combustion reached 32.8 billion tons in 2017 according to the International Energy Agency. China, the largest contributor, was responsible for 28% of these emissions, followed by the United States (14%), the European Union as a whole (10%), India (7%), Russia (5%), Japan (3%), Korea (2%), Canada (2%), Indonesia (2%), and Iran(2%). All other countries produced about 25% of emissions. The 20 countries with the highest carbon dioxide emissions (in million tons (Mt)) are: 1. China (9,300 Mt) 2. The United States (4,800 Mt) 3.
