Evaluation of climate policy measures over two decades finds many have failed to achieve necessary emissions reductions

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 journal
Science, this 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 emissions reductions.
Only 63 cases of successful climate policies, each leading to average emission reductions of 19%, were identified. The key characteristic of these successful cases is the inclusion of tax and price incentives in well-designed policy mixes.
Much of the debate about climate policy centers on which climate policy instruments work in reducing emissions, and which do not. Yet prior evaluations have focused on a limited range of headline policies, neglecting hundreds of other measures.
