Emissions by sector - Our World in Data

To prevent severe climate change we need to rapidly reduce global greenhouse gas emissions. The world emits around 50 billion tonnes of greenhouse gases each year [measured in carbon dioxide equivalents (CO 2 eq)]. 1 . To figure out how we can most effectively reduce emissions and what emissions can and can’t be eliminated with current technologies, we need to first understand where
