EU Considers Weakening 2040 Climate Target Over Forest CO₂ Absorption

The European Union is considering introducing a “brake clause” into its planned 2040 climate target that would allow the goal to be revised downward if forest and land-use sectors fail to absorb sufficient CO₂ emissions. This comes amid concerns that forest absorption has dropped nearly a third over the past decade, due to wildfires, pests and worsening forest health.

Under the proposed draft compromise, the EU would retain its aim to cut net emissions by 90% by 2040 compared to 1990 levels-but if land-based carbon sinks under-perform, an “adjustment of the 2040 intermediate target corresponding to and within the limits of the possible shortfalls” could be triggered. In addition, the draft would enable periodic reviews of the target every two years, giving the possibility of weakening it if progress is slower than expected.

This shift raises questions about the integrity of the EU’s climate leadership and whether such flexibility will undermine investor confidence in long-term decarbonisation pathways. With just days to go before the COP30 climate summit, EU ministers must still iron out details-such as the share of emission reductions that can be met via foreign carbon credits-before the target can formally be adopted.

The proposed "brake clause" on the 2040 target - allowing downward revision if land-based carbon sinks underperform - reflects a real biological challenge: European forest CO2 absorption has fallen roughly one-third over the past decade due to wildfires, pests and climate-stress-related tree mortality. Land-sector performance risk is genuine, not speculative.

However, the mechanism introduces significant political risk to EU climate credibility. Investors and industrial operators have built long-horizon capital-allocation decisions around EU target trajectories; retrospective flexibility reduces the reliability of those anchor points and undermines the "policy certainty" the EU regulatory architecture has traditionally provided. The share of international carbon credits allowable in the target remains a contentious variable.
