The EU have already walked back a touch and have recently announced some reductions to the corporate reportings required around Sustainability/Green issues.

Well, that is apart from China, who are gleefully making all the solar cells and EVs to sell to environmentally conscious Europeans & Yanks whilst they continue to generate >50% of their electricity from coal. They are playing the game very well...
