CO2emissioner
CO2emissioner refers to the release of carbon dioxide into the atmosphere, a key factor in climate change due to its long atmospheric lifetime and heat-trapping properties. The term is used across environmental science, policy, and reporting to describe both current emissions and trends in their sources and magnitude.
Major sources include burning fossil fuels for electricity and heat, transportation (vehicles, aviation, shipping), industrial processes
Emissions are quantified in gigatonnes of CO2 per year (GtCO2/yr) and can be expressed as CO2-equivalents (CO2e)
Mitigation aims to reduce CO2emissioner through decarbonizing energy, improving energy efficiency, electrification of transport and industry,
Internationally, efforts are coordinated under the UNFCCC and the Paris Agreement, with countries outlining Nationally Determined
