Bonn: The 2040 climate target is now binding law, and the question has shifted from whether Europe will set a goal to how it will deliver one. The Council adopted the amended European Climate Law on 5 March 2026, fixing a 90 percent net cut in greenhouse gas emissions by 2040 compared with 1990 levels.
What the 2040 climate target requires
In plain terms, the 2040 climate target commits the EU to cut net emissions by nine tenths within fourteen years. That pace is faster than the average of recent decades, and it requires deeper change in power, industry and transport.
The Commission proposed the amendment on 2 July 2025, and Council and Parliament reached agreement on 10 December 2025. The law builds on the 2021 Climate Law, which set climate neutrality for 2050 and at least 55 percent net reductions by 2030.
The new goal sits on the path between those two points. A 90 percent cut leaves residual emissions that the EU must offset with removals, so the target sets the pace for forests, soils and industrial carbon capture as much as for power plants.
How international credits change the maths
From 2036, high-quality international credits may count towards the goal, up to 5 percent of 1990 net emissions. At least 85 percent of reductions must therefore come from inside the EU. The credits must rest on credible reduction activities in partner countries and follow the Paris Agreement.
This flexibility is a political compromise. Governments with heavy industry wanted a safety valve, and environmental groups worried about weak offsets. The 2036 start date and the 5 percent cap limit that risk, but quality rules for credits will decide whether the risk becomes real.
Why the review clause matters
The law requires a review every two years. The Commission must assess progress against competitiveness, energy prices, EU net removals and the flexibility to use international credits for post-2030 targets, and it must propose revisions or extra measures where needed.
Investors should read this clause carefully, because the 2040 climate target will shape capital allocation for the next decade. It anchors the target while leaving room for adjustment, and each review will become a moment of negotiation between climate ambition and industrial concerns. Predictability may suffer in each review year.
ETS2 and the delivery gap
The same package moved the start of full operation of ETS2, which covers road transport and buildings, from 2027 to 2028. That decision gives households and fuel suppliers an extra year, but it also pushes carbon pricing for the hardest sectors closer to 2030, leaving less time to cut emissions there.
Delivery of the 2040 climate target now depends on follow-up legislation. The Commission must prepare proposals to implement the target, including a role for permanent carbon removals within the emissions trading system and greater flexibility across sectors and instruments.
What happens next
Expect the debate to shift to the post-2030 framework: renewable and efficiency targets, the ETS cap, and the funding to support it. The Commission’s implementation proposals will set the tone. The 2040 climate target gives Europe a destination, and every review will test the route, but the legislation that follows will show whether the EU can reach it without losing support at home.
