In May 2021, the German government proposed to reduce emissions by 65% by 2030 compared to 1990 levels. In June 2021, the new goal was enshrined in the amended Climate Protection Law.21 While it is step forward, the country has not yet aligned its policies to its target: current policy projections would result in emissions falling by only 49% by 2030.4
Compatibility with 1.5°C pathways requires Germany to increase its 2030 emissions reduction goal to 68-76% by 2030 below 1990 levels.
The new EU emissions reduction goal also makes it necessary for Germany to significantly increase its goal as it has a much higher capability to do more than most other EU member states. Germany’s emissions per capita are still quite high – over 20% above EU average.
Long term pathway
In addition to increasing its 2030 emissions reduction goal, the amendment of the Climate Protection Law from June 2021, also included an emissions reduction goal of 88% by 2040. Germany should reach net zero GHG by 2048. Current policies adopted by March 2021 would only result in emissions reduction of 67%.
This is a significant improvement from the initial version of the Climate Protection Law, however in order to be 1.5°C compatible, Germany should target emissions levels no higher than 27-84 MtCO₂e/yr or a reduction of 93-102% by 2050, including the use of BECCS, but excluding LULUCF emissions.30
While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries such as Germany, they underestimate the feasible space for such countries to reach net zero earlier.
Recent studies indicate a potential of around 63 MtCO₂e/yr of carbon dioxide removal (CDR) technologies by 2045 for Germany.5 Given that the land sector in Germany is limited, and even projected to become a source, the country would need to implement CDR technologies to compensate these remaining positive emissions.

30 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement. A wide assessment database of these new scenarios is not yet available, thus we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches which developed countries will need to implement in order to counterbalance their remaining emissions and reach net zero GHG are not considered here due to data availability.
31 Benchmarks here provided are derived from the illustrative pathway CEMICS-1.5-CDR8_REMIND_1.7 (28 MtCO₂e) and the 25th percentile (47 MtCO₂e) of the analysis 1.5°C compatible pathways in this analysis, assessed by the IPCCSR1.5. See methodology section for more information.
32Confirming previous analysis indicating that: “Germany needs to phase coal out of its electricity sector by 2030 to meet its obligations under the Paris Agreement. This is earlier than the dates discussed so far by the Coal Commission, a body established to come up with a coal exit plan by the end of 2018.”29
33 According to the Carbon Contracts for Difference, investor in low carbon technology (e.g. low carbon steel) receives subsidy that amounts to the different between the cost of producing traditional product and the low carbon alternative. This amount is reduced by what the investor would have to pay in carbon price anyway, e.g. in the framework of the EU ETS.
Accelerating development of renewables and an earlier coal phase-out would significantly reduce the emissions intensity of Germany’s electricity sector. However, Germany also needs to accelerate development of renewables in other sectors, especially in transport and heating. Importantly, all 1.5°C compatible scenarios lead to a decrease in energy consumption, in some cases by more than 50%. This indicates the need to increase energy efficiency, especially in the buildings and transport sectors.
Our analysis show that by 2050 almost all energy could be produced from renewables, with its shares increasing rapidly in all sectors in the 2020s and 2030s. Negative emissions in the form of biomass with CCS scale up slowly in the 2020s, but their share increases much faster in the 2040s. Scenarios with the highest improvements in energy efficiency and the fastest development of renewables, require the lowest share of negative emissions.
Key emissions benchmarks of Paris compatible Pathways for Germany. The 1.5°C compatible range is based on the Paris Agreement compatible pathways from the IPCC SR1.5 filtered with sustainability criteria. The median (50th percentile) to 5th percentile and middle of the range are provided here. Relative reductions are provided based on the reference year.
