Both Poland and France have committed to reach a globally binding deal on the transition to more sustainable sources of energy. Yet, they still disagree about the methodology. France, in broad agreement with the European Commission, intends to secure for itself an exemplary reputation ahead of next year’s COP21 in Paris. Already at the March European Council it will take the opportunity to push for targets for the EU by 2030. To solve the Franco–Polish deadlock and strengthen the EU’s negotiating position, Warsaw could usefully push for the EU to carry out an assessment of transition on a broad range of economic sectors. This would result in a shared and equitable commitment, taking into account both the necessity of ambitious EU objectives and the continued existence of deep imbalances between national energy mixes.
