In December 2020, the European Commission presented its long-awaited proposal for a Battery Regulation. The proposed legislation introduces mandatory requirements for all batteries placed on the EU market, and sets targets on collection, treatment and recycling of batteries at the end of their life. This joint paper by Amnesty International and Transport & Environment sets out the most critical shortcomings of the due diligence regime presented in the proposed Regulation. It is essential that the European Parliament and Council correct these shortcomings and approve legislation that effectively protects human rights and the environment, rather than sacrificing these core principles in the race to implement the energy transition.
