Abstract

Meeting the Paris Agreement’s climate targets necessitates better knowledge about which climate policies work in reducing emissions at the necessary scale. We provide a global, systematic ex post evaluation to identify policy combinations that have led to large emission reductions out of 1500 climate policies implemented between 1998 and 2022 across 41 countries from six continents. Our approach integrates a comprehensive climate policy database with a machine learning–based extension of the common difference-in-differences approach. We identified 63 successful policy interventions with total emission reductions between 0.6 billion and 1.8 billion metric tonnes CO2. Our insights on effective but rarely studied policy combinations highlight the important role of price-based instruments in well-designed policy mixes and the policy efforts necessary for closing the emissions gap.

Both Holman Jenkins and yourself are dead wrong...PLUS...nowhere in the 'Science' Study is reality of Global Warming/Climate Change challenged. The authors are simply offering a means of choosing the more efficient policies for reducing CO2 concentrations in the atmosphere. IMO, once GEN-IV Nuclear Reactors come on line in the 2030 time frame, the path and policies will become much clearer.
