Map 08.04 Carbon Dioxide Emissions - Arranged by Sectors and Floor Spaces

Map 08.04.1 CO2 Emissions of all Recorded Polluters per Square Meter of the Effective Floor Space

This map shows specific CO2 emissions per square meter for all use domains. Measuring the building area eliminates the influence of block size and enables better comparisons of emission data.

The gradient, particularly between the city center and outlying areas, falls back to a relatively homogeneous distribution. The energy demand and/or CO2 emissions per sq. meter differ indeed considerably, but the extremes clearly flatten out. Emission centers are formed particularly by capital-intensive, and thus often energy-intensive, industries. Areas of intensive industrial use (cf. Goerzallee, Am Juliusturm/Nonnendammallee, Grünau/Teltowkanal, etc.) become clear. There are also clearly higher CO2 emissions for parts of the universities, and for individual special uses such as the Tierpark, zoo, and the sport and recreation center in Friedrichshain.

Map 08.04.2 CO2 Emissions from Electricity Consumption per Square Meter of the Effective Floor Space

The map shows the CO2 emissions per sq. meter of effective floor space which are solely due to electricity consumption. Electricity is evaluated for the entire city with a uniform emission factor, so the map also corresponds to a floor-space related depiction of electricity consumption intensity.

The marked area differences of CO2 emissions from electricity supply show a chear difference between the previously separated areas of the city (cf. the bordering districts of Wedding and Prenzlauer Berg). This difference is primarily due to different patterns of household electricity consumption. In 1995 average household electricity consumption in East Berlin was about one-fourth below West Berlin. The average number of inhabitants per household in East Berlin was 5 % greater than in West Berlin (BEWAG 1997, BMWi 1997). Household consumption of electricity was about 30 % lower in East Berlin than in West Berlin. Large industrial areas are intensive electricity and emission locations. They are depicted with greater differentiation than in Map 8.03.

Map 08.04.3 CO2 Emissions of Households without an Emission Share from the Public Electricity Supply

More than three-quarters of household CO2 emissions are caused by production of heating. The space heating demand and/or the CO2 emissions related to it, depend on the area to be heated as well as the heating insulation and/or the heating system used, such as district heating, fuel oil, natural gas, coal, etc. Map 08.04.3 depicts CO2 emissions from households in absolute numbers, but without the emissions calculated from electricity consumption. It thus initially reflects the density situation presented in Map 08.03. The city center areas in particular, but also the large settlements of Marzahn, Hellersdorf and the Märkisches Viertel, show high emission values. This effect is overlaid in the Prenzlauer Berg and Friedrichshain districts especially, but also the Kreuzberg and Neukölln districts. These districts use more household coal heating furnaces that produce above-average emissions.

Map 08.04.4 CO2 Emissions from Public Facilities, Industry/Commerce, Trade and Service Sectors, without Emission Share from the Public Electrical Supply

The map depicts CO2 emissions for all value producing (economic activity) sectors, without inclusion of emissions calculated from electrical consumption. The map shows two clear differing distribution patterns for CO2 emissions resulting from value production.

Value production (economic) activities cause almost homogeneous CO2 emissions at a comparatively low level across the entire city area. Primary polluters are mainly small and medium enterprises and the diverse decentralized services of the public and private sectors. There is also a clear number of focuses of CO2 emissions from centers of industrial production, trade (Westhafen, Hermannplatz), and services (universities, Alexanderplatz square). It is to be emphasized that these emission focuses are located less often in the city center and more often in the direction of the outlying areas, and that they form a belt around the inner city areas.
