CO2 emissions cover any release of carbon dioxide, also known as carbonic gas, into the atmosphere.

Carbon dioxide is a chemical compound that comprises one carbon atom bonded to two oxygen atoms, referred to by the formula CO2. It is produced during the aerobic fermentation or combustion of organic compounds, and is exhaled and released by people and plants.

CO2 emissions caused by human pollution continue to grow and exacerbate global warming. The energy transition act aims to curb greenhouse gases (GHG), including CO2.
