Why it’s so hard to tell which climate policies actually work

NATIONAL CLIMATE insurance policies are a comparatively latest invention. In 1997, in accordance with the Grantham Institute, a think-tank on the London Faculty of Economics, there have been 60; by 2022 the quantity had risen to virtually 3,000. Their effectiveness has proved virtually inconceivable to measure. In August, a world analysis group printed the primary world analysis of local weather insurance policies in Science, a journal. The examine, which checked out round 1,500 insurance policies applied in 41 nations between 1998 and 2022, discovered that simply 63 may very well be linked to sizeable reductions in emissions.
