Katowice: In the Silesian coal country that has long defined Poland’s industrial identity, the European Union’s newest legal obligation lands with particular weight. After more than a year of negotiation, the amended European Climate Law entered into force in April 2026, writing a binding interim target into the bloc’s statute book: a 90 percent net cut in greenhouse gas emissions by 2040, measured against 1990 levels. The figure is no longer an aspiration in a Commission communication. It is law.
## What the new target actually requires
The 2040 goal sits between the existing 2030 commitment, a 55 percent reduction, and the 2050 climate-neutrality objective. Crucially, the final text reached by Parliament and Council negotiators in December 2025 and ratified by the Council on 5 March 2026 specifies how the cut must be achieved. At least 85 percent of the target has to come from domestic reductions inside the Union, with a capped contribution of up to 5 percentage points drawn from high-quality international carbon credits. That flexibility was the price of agreement, and it remains the most contested feature of the deal.
## Why the carbon-credit clause matters
Supporters argue the international-credit window keeps the target politically survivable for member states with heavy industry and coal exposure, the Polish and Czech economies foremost among them. Critics counter that offsets bought abroad risk diluting the domestic transformation the law is meant to force, and that historically such credits have been hard to verify. Both readings are defensible, and the integrity rules the Commission must now write will decide which one proves correct.
## The compliance machinery
With the headline number fixed, attention shifts to the instruments that deliver it: the emissions trading system, the carbon border levy, sectoral rules on transport and buildings, and the next national energy and climate plans that capitals must submit. None of these is automatic. Each carries its own distributional fight, and the 2040 figure now functions as the legal anchor against which every one of them will be judged.
## What happens next
The Commission is expected to translate the target into concrete sectoral legislation over the coming years, including a revised post-2030 framework. For regions like Silesia, the practical question is whether the promised transition funding arrives fast enough to make a 90 percent cut feel like an opportunity rather than a sentence. The law has settled the destination. It has not settled who pays for the journey, and that argument is only beginning.
