Can someone quantify these "huge economic benefits" !?
Chris Skidmore MP published his Net Zero Review in January (press release here). It's a long and detailed 340-page report, but here's just one paragraph:
446.The UK can take a share of the global economic prize from the transition, but it must act now. The UN’s Net Zero Asset Managers initiative recently announced that nearly a third of the $66 trillion of assets managed by their members globally are committed to net zero with tangible decarbonisation goals. Additionally, McKinsey have estimated that supplying the goods and services to enable the global net zero transition could be worth over £1 trillion to UK businesses between 2021 and 2030.
Of course, the former Party of Business (now the F*k Business Party) stuck their fingers in their ears.
