Summary

Sixty-three percent of large companies worldwide had made a net zero commitment by 2023, up from close to none in 2018. But if the target date is 2050, that's several corporate lifetimes away, and the planet needs emission reductions today. What actually changes in the boardroom when a pledge is signed? Simon Dietz (LSE, CEPR) has tracked climate management practices and emissions at nearly 2,000 companies to find out. He tells Tim Phillips that the picture is not the one that either side of the debate might expect. A net zero pledge doesn't usually signify an immediate cut in emissions, but there is a clear and early shift in how companies plan for net zero that has often started before the announcement. What is left is something is harder to spot: firms making a strategic pivot, of which the public commitment is only one part.
