Emission intensity

Emission intensity is the greenhouse gas emitted over the life of a generator per unit of electricity generated. The emission intensity of coal power stations is high, as they emit around 1000 g of CO eq for each kWh generated, while natural gas is medium-emission intensity at around 500 g CO eq per kWh. The emission intensity of coal varies with type and generator technology and exceeds 1200 g per kWh in some countries.
