• The Polish government says it will keep pursuing changes to the EU rules.

Court rejects every Polish challenge

The Court of Justice of the European Union has dismissed all seven actions brought by Poland against legislative acts of the 'Fit for 55' package (Polska przegrała w TSUE. Rząd zapowiada dalszą walkę. "Pracujemy w inny sposób" – Business Insider Polska) (TSUE oddalił wszystkie skargi Polski na Fit for 55 – Prawo.pl) (TSUE oddalił siedem skarg Polski. Chodzi o unijny pakiet „Gotowi na 55” – GazetaPrawna.pl). The ruling came on Thursday, 12 November (Polskie skargi na plan neutralności klimatycznej Unii Europejskiej oddalone przez TSUE – Rzeczpospolita) (TSUE oddala polskie skargi. Jest decyzja – Business Insider Polska) (TSUE oddalił siedem polskich skarg na pakiet klimatyczny "Gotowi na 55" – Bankier.pl). The package aims to cut greenhouse gas emissions in the EU by at least 55 percent by 2030 compared with 1990 levels, and to reach climate neutrality by 2050.

What Poland challenged

The contested acts cover emission standards for cars, the emissions trading system and energy efficiency. The former government filed the complaints during the 2023 election campaign (ETS, CBAM i zakaz sprzedaży aut spalinowych. Dziś ważny wrok TSUE ws. "Fit for 55" – WNP.pl). The emissions trading system, known as ETS, and the carbon border adjustment mechanism, CBAM, are among the regulations at the centre of the dispute.

Government signals it will continue

The Polish government has said it does not intend to stop efforts to change the EU rules, which include but are not limited to the emissions trading system. Officials indicated that the country will pursue its aims through other channels.

Other rulings the same day

The court was scheduled to deliver several other judgments on Thursday that concern Poland (Kalendarium 12.11.2026: co wydarzy się w czwartek 12 listopada 2026 roku? Spotkanie prezydentów Polski i Słowacji, szczyt europejskich przywódców w Dublinie i ważne wyroki TSUE – TVP INFO).
