Home energy on your own country's grid, heating, car, flights, diet and shopping, in tonnes CO₂e per person. Compares the result with your country, the world and the 1.5 °C target, and ranks the actions that cut most for you.
Carbon & climateElectricity kWh → CO₂
Converts any amount of electricity into CO₂ using the latest average grid carbon intensity of 210+ countries, and shows how the same kWh would score on cleaner and dirtier grids.
