Energy supplies

The largest proportion of greenhouse gases emitted in Germany consists of energy-related CO2. Almost half of this is produced by the power industry, which makes up by far the largest proportion. Electricity generation is the most significant conversion area; the power plants alone produce around 37% of the emissions. In this respect it should be noted that emissions caused by the generation of electricity (or other secondary energy sources such as district heating) must be classified in the sectors that ultimately use these secondary energy sources (polluter pays principle). If the individual energy sources are considered as emitters, the mineral oil products are the main pollutants with 288 million tonnes a year in 2006. Lignite, which makes up just 11% of the primary energy consumption, actually contributed to 19% of (energy-related) CO2 emissions in 2006.
