This website summarizes the preliminary findings of two pilot studies of the Climate Action Science project. We constantly update this page and add additional information.

CO2 emissions by sector distributed over the population

The annual per capita CO2 emissions of all sectors combined are currently around 9.6 tons CO2 equivalents* in Germany, which is about twice as high as the international average of 4.8 tons per capita** BMU. For the sectors in Germany, the average CO2 emissions for 2018, distributed over the population, are approximately: (tons CO2 equivalents) Industry: 2.16, traffic: 1.95, households: 1.06, commerce: 0.44 and public buildings: 0.04 - 0.07***.
The average values for the municipalities of the Rhine-Neckar district and Heidelberg distributed over the population for the years 2010 to 2017 are shown on the following map.

The map shows the CO2 emissions in CO2* equivalents and per capita**.

The methodology behind the data is based on a territorial balance. What this means in detail, is explained in the following section.

Territorial balance

All consumption in the district is balanced on the level of final energy. Final energy is the primary energy arriving at the consumer after deduction of transmission losses. Energy that is contained in products and hotel stays outside the district are not balanced.

Upstream chain

The emissions of the upstream processes are included in the calculation. Thus emissions for the extraction of raw materials, transport and transformation outside the district are also included. The individual factors come from the GEMIS data set and the calculations of IFEU Heidelberg.

Private households:

Energy consumption of private end consumers.

Manufacturing industry:

All manufacturing companies with more than 20 employees recorded by the State Statistical Office.

Municipal real estate in the cities and municipalities:

All consumption data of administrative buildings, schools and day-care centers.

Trade and other:

All energy consumers not included in the other sectors. It includes trade, commerce and services, smaller industrial companies (with less than 20 employees) and agriculture.

Besides CO2, other greenhouse gases contribute to global warming. For comparison purposes, they are converted into CO2 according to their warming potential (Federal Office for the Environment).
