Greenhouse gas emissions

Greenhouse gas emissions from human activities intensify the greenhouse effect which contributes to climate change. Carbon dioxide from burning fossil fuels is the main cause of climate change. The largest annual emissions are from China followed by the United States, which has higher emissions per capita.

The main producers fueling the emissions globally are large oil and gas companies.
Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels.
The growing levels of emissions have varied, but have been consistent among all greenhouse gases.
