BRUSSELS — The European Union’s environment ministers struck a deal watering down a proposed 2040 target for cutting planet-warming emissions and set a new 2035 climate plan. Following marathon negotiations all day Tuesday and into Wednesday morning, ministers unanimously approved the bloc’s long-overdue climate plan, rescuing the EU from the international embarrassment of showing up empty handed this month’s COP30 summit. The plan, which is a requirement under the Paris Agreement, sets a new goal to slash EU emissions between 66.25 percent and 72.5 percent below 1990 levels until 2035. That plan is not legally binding but sets the direction of EU climate policy for the coming five years. The range is similar to an informal statement that the EU presented at a climate summit in New York in September. Ministers also adopted a legally-binding target for cutting emissions in the EU by 85 percent by 2040. The deal mandates that another 5 percent reduction be achieved by outsourcing pollution cuts abroad through the purchase of international carbon credits. On top of that, governments would be allowed to use credits to outsource another 5 percentage points of their national emissions reduction goals. Ministers also backed a wide-ranging review clause that allows the EU to adjust its 2040 target in the future if climate policy proves to have negative impacts on the EU’s economy. The deal also foresees a one-year delay to the implementation of the EU’s new carbon market for heating and car emissions, which is set to start in 2027. Hungary, Slovakia and Poland did not support the 2040 deal, while Bulgaria and Belgium abstained. The rest of the EU27 countries backed it. Lawmakers in the European Parliament now have to agree on their own position on the 2040 climate target and negotiate with the Council of the EU before the target becomes law.
