Transcription

1 How the transport sector could contribute to national climate targets Stefan Schönberger, BCG Ludwigsburg, February 1, Climate Paths for Germany

2 Unique fact base Broad validation of results All sectors Analysis level: individual GHG reduction measures Optimized to minimize GHG abatement costs Investments, costs, GDP effects 68 industry associations and companies ~ 00 industry experts ~ 40 workshops Scientific board 1

3 Agenda for today Overview on climate paths for Germany: all sectors Deep-dive transport sector Investments, costs and macroeconomic implications

4 Greenhouse gas (GHG) emissions in Germany Mt CO e 61% GHG reduction under "current policies" scenario, but major gap to national reduction targets 1,51 Mt 015: 90 Mt NRT NRT = national reduction targets of the German government (corridor) -61% NRT Current policies 80% climate path 95% climate path 3

5 Greenhouse gas (GHG) emissions in Germany Mt CO e 1,51 Mt 015: 90 Mt but a major gap to national reduction target remains NRT NRT = national reduction targets of the German government (corridor) -61% 80% NRT 95% Gap: 19-34% 4

6 80% path achievable with existing technologies Power: 40 GW wind and PV, grid expansion Power: Gas gradually replaces coal in backup generation Buildings: 50% more insulation/refurbishments (1.7% p.a.) Buildings: Expanded urban district heating Buildings: 11 million heat pumps, mainly in 1- to -family homes PV = Photovoltaik Alle Zahlen beziehen sich auf Industry: 90% penetration of efficiency technologies Industry: Concentration of national solid biomass for heat < 500 C Transport: 6M electric vehicles, /3 of passenger cars Transport: 4,000 km of electric overhead lines for highway trucks Agriculture: More efficient use of fertilizer 5

7 95% path pushes boundaries of technology and acceptance 340 TWh Imports of renewable fuels (PtL, PtG) Power: 40 9 GW wind and PV, grid expansion Power: Gas 100% gradually renewable replaces through PtG, coalgas in grid backup becomesgeneration seasonal storage Buildings: 70% 50% more insulation/refurbishments (1.9% (1.7% p.a.) Buildings: Heating Expanded free of fossil urban fuels district (through heating 14M. heat pumps and 100% Buildings: 11M heat pumps, renewable district heating) mainly in 1- to -family homes PtL = Power-to-Liquid, PtG = Power-to-Gas Alle Zahlen beziehen sich auf Industry: 90% 100 % penetration renewable heat and of steam efficiency throughtechnologies biogas and PtG Industry: Concentration produced with of recycled national carbon solid biomass from biomass for heat incineration < 500 C Transport: 6M 31M electric vehicles, vehicles, 4/5 of passenger /3 of passenger cars cars Transport: 4,000 8,000 km of electric overhead lines for highway trucks Agriculture: More "Methane pill" efficient for cattleuse population of fertilizer Carbon capture and storage for steel, cement, ammonia, refineries, and waste combustion 6
