Figure 10: Emission developments of households (left) and the services sector (right) in Mt CO₂eq based on the 'Business as usual' and ZERO basis scenarios of the EP2050+. Source: Prognos/TEP Energy/Infras/Ecoplan 2020. Figure 10 shows the possible development of emissions from households and in the services sector according to EP2050+ to 2050. A reduction to zero for households is possible by 2050, but there are low levels of remaining emissions from older infrastructure in the services sector. The comparison with the 'Business as usual' scenario clearly shows that much greater efforts are needed to maintain the reduction pathway towards net-zero emissions. According to the EP2050+, the decarbonisation of the heating supply system is the first main lever for reducing the greenhouse gas emissions of households. Heating supply will continue to make up the biggest part of energy requirements long-term. It is mainly met today by heating oil and natural gas. These fossil energies must be replaced by emission-free alternatives by 2050. Figure 11 shows the development of energy consumption in the ZERO basis scenario according to EP2050+.
