36 civil society groups including T&E, Amnesty International, Friends of the Earth Europe, Bellona, Global Witness and European Environmental Bureau have expressed concern about due diligence rules that are supposed to protect against abuses in the battery supply chain. The groups say that all types of batteries need to be covered by the due diligence rules, as well as all types of businesses, including SMEs. It should not matter whether the batteries are used in phones or for energy storage – the materials used to make them have sometimes been linked to human rights and environmental harm.
