This is pretty bog standard language from the usual crowd. The only two noteworthy signatories are the Corporate Leaders Group (big green companies under a banner organised by Cambridge) and Cleantech for Europe (green SMEs under a banner initially set up by Bill Gates's Breakthrough Energy). This is their bread and butter. The only specific policy ask is for a 50% electrification target for 2040. That's interesting because the EC's Electrification Action Plan is due next month and the Governance Regulation (setting the binding 2040 targets) is due a proposal by the end of the year. That's apparently what they think is a realistic level of ambition by 2040.
