08/23/2024 - An international research team has unveiled the first comprehensive global evaluation of 1,500 climate policy measures from 41 countries across six continents. Published in the prestigious journal Science, this unprecedented study provides a detailed impact analysis of the wide range of climate policy measures implemented over the last two decades. The findings reveal a sobering reality: many policy measures have failed to achieve the necessary scale of emission reductions. Only 63 cases of successful climate policies, leading to average emission reductions of 19 percent, were identified. The key characteristic of these successful cases is the inclusion of tax and price incentives in well-designed policy mixes.
