Achieving 1.5°C compatibility would require the EU to reduce emissions to 68% below 1990 levels excluding LULUCF by 2030 (roughly 1548 MtCO₂e excluding LULUCF sinks). This is 51% below EU’s approximated emissions in 2020, excluding LULUCF. Reaching this goal requires a significant acceleration in emissions reductions of at least 174 MtCO₂e/yr between 2021-2030. To compare, coal phase-out and the development of renewables between 2011-2018 resulted in average yearly emissions reductions of 53 MtCO₂e/yr.
The current goal of reducing emissions of ‘at least 55%’ incl. LULUCF (53% excl. LULUCF), would leave an emissions gap of 713 MtCO₂e/yr in 2030.
In addition to strengthening its emissions reduction goal, the EU also needs to strengthen its policies to reach more ambitious goals. The policies adopted by the EU and its member states would only result in emissions reductions of 41-47% (excl. LULUCF).
Long term pathway
To be compatible with 1.5°C pathways, the EU’s emissions (excl. LULUCF) need to fall by 93% below 1990 levels or 355 MtCO₂e/yr by 2050.15 The majority of these remaining emissions will be from the agriculture sector, and in some scenarios, from the industry sector. Emissions from the energy sector are projected to be negative by the 2040s, and even the late 2030s in some scenarios.16
According to the EU’s analysis conducted in 2018 for the EU27+UK, estimates that EU would need reduce emissions by between 95% (for Scenario 1.5TECH) and 92% (for Scenario 1.5LIFE) to reach a net zero goal. The remaining emissions would be almost completely balanced by sinks from LULUCF.

15 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.
16 In analysed global-least cost pathways assessed by the IPCC Special Report 1.5°C, the energy sector assumes already a certain amount of carbon dioxide removal technologies, in this case bioenergy carbon capture and storage (BECCS).
Analysed 1.5°C compatible emissions scenarios show that CO₂ emissions need to decrease by 61-74% by 2030 compared to 1990 levels, and reach reduction levels of 97-104% by 2050. Scenarios with the slowest emissions reductions to 2050 require much higher levels of negative emissions in the second half of the century. Depending on the scenario, the deployment of negative emissions starts between 2045 and 2064.
Almost all scenarios indicate a decrease in primary energy consumption – by 9-34% in 2030 and 2-37% in 2050. In the latter case, only one scenario with high reliance on negative emissions results in an increase in energy consumption – up 9% from 2017.
Our scenarios show renewables have the potential to generate up to 100% of electricity by the middle of the century. The rest of the electricity would need to come from carbon dioxide removal technologies such as BECCS and nuclear.
Key emissions benchmarks of Paris compatible Pathways for the European Union. 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.
