In this joint letter, Carbon Market Watch, WWF, CAN Europe, the EEB and other environmental organisations call on the European Parliament’s Industry, Research and Energy Committee (ITRE) to vote for ambitious reforms to the European Union’s Emissions Trading System (EU ETS) that will ensure that the EU’s carbon market will benefit the climate and lead to sustainable industrial decarbonisation in Europe. The green groups call on MEPs to scrap free pollution permits and to use the generated revenues to invest in effective climate action.
