CO2 emissions

Around 85% of anthropogenic greenhouse gas emissions come from the energy sector. Of these gases, CO ₂ has the largest contribution with 95% of emissions. Electricity generation is responsible for almost 40% of global greenhouse gas emissions.

When it comes to emissions from the energy sector, coal is the most emitting source, accounting for 44% of CO ₂ emissions. Oil contributes 36% and natural gas 20%. These emissions come from the production and use of energy in the industrial, service, transport and residential sectors.

Transport emits CO ₂ when fuel is burned, whether diesel (land vehicles or boats), petrol (cars) or kerosene (aircraft). To give some orders of magnitude for vehicles, we have the following...
