A new study finds that the most effective climate policies require polluters to bear financial costs, revealing that such measures lead to significant reductions in carbon emissions.
Seth Borenstein reports for The Associated Press.
In short:
- Researchers analyzed 1,500 global climate policies, finding only 63 cases since 1998 where emissions dropped significantly.
- Policies combining regulations with energy taxes or costs were most successful, particularly in the UK’s electricity sector.
- Even successful policies have only made a small dent in global carbon emissions, showing the need for more aggressive actions.
Key quote:
“The key ingredient if you want to reduce emissions is that you have pricing in the policy mix.”
— Nicolas Koch, climate economist at the Potsdam Institute for Climate Impact Research
Why this matters:
Effective climate policies that make polluters pay are essential for reducing global emissions, but current efforts are insufficient. Without more robust actions, the world may struggle to meet critical climate targets.
