Most climate policies don’t work. Here’s what science says does reduce emissions. - C C - Aug 25, 2024
Out of 1,500, only 63 climate change interventions led to significant reductions in carbon emissions

EXCERPTS: Researchers used machine learning to analyse roughly 1,500 climate policies and identify those that have dramatically reduced carbon emissions. Their study, published in Science today, found that policies that combine several tools are more effective in slashing emissions than are stand-alone measures.
[...] For other researchers, the paper is alarming. “This study provides a warning to countries around the world that their climate policies have had very limited effects so far,” says Xu Chi, an ecologist at Nanjing University. “Existing polices will need to be re-evaluated, and changes will need to be made,” Xu adds.

INTRO: An evaluation of more than 1,500 climate policies in 41 countries found that only 63 actually worked to reduce greenhouse gas emissions.
Subsidies and regulations—policy types often favored by governments—rarely worked to reduce emissions, the study found, unless they were combined with price-based strategies aimed at changing consumer and corporate behavior.
“The commonality in those successful cases is where we see subsidies and regulations being combined with price-based policy instruments,” said Nicolas Koch, senior researcher at the Berlin-based Mercator Research Institute on Global Commons and Climate Change and an author of the study. “This means carbon pricing, and it could be energy taxes, it could be vehicle taxes.”
The study, published today in the journal Science, used an AI algorithm to sift through a database of environmental prescriptions compiled by the Organization for Economic Cooperation and Development, a Paris-based economic agency, between 1998 and 2020. These policies ranged from energy-efficient standards for household appliances to a carbon tax on fossil fuels like oil and gas.
The fraction of policies that worked combined financial incentives, regulations and taxes, according to the study....
