Combined heat and power generationGreenhouse gas emissions in comparison

The graphic shows how combined heat and power generation (CHP) enables the CO₂ emissions per kilowatt-hour of electricity to be reduced relative to conventional electricity generation. With these calculations according to the Global Emission Model for Integrated Systems (GEMIS), not only are the direct emissions caused by combustion in the plant taken into account but also the preliminary stages, including the production and transport of the fuel and the manufacture of the plant.
