A recent peer-reviewed study, published in Climate Policy, evaluated climate policies across 40 countries over a 32-year period. The research indicates that carbon pricing, taxation, and investments in renewable energy and research are effective government tools for reducing CO₂ emissions.
The study observed successful implementation in countries like Sweden and Norway, which utilized a broad mix of climate policies.
It concludes that a comprehensive and diverse policy approach yields greater benefits than reliance on a single measure.
Researchers from the University of Barcelona, University of Lausanne, LMU Munich, and University of Oslo conducted the study. They stated that effective climate action results from the implementation of multiple measures over time, rather than identifying one "optimal" policy.
The study provides country-specific assessments for potential emissions reductions and employed a novel methodological approach to model multiple climate policy parameters simultaneously.
Key Findings
- Australia, Canada, and Japan were identified as countries with substantial potential to enhance climate performance by increasing fossil fuel excise taxes.
- The paper identifies core climate policy measures that consistently strengthen climate ambition across various national policy mixes.
- A new methodological toolkit for evaluating climate policies, applicable to other rapidly expanding policy areas, was introduced.
Insights from the Lead Author
Dr. Yves Steinebach, lead author from the University of Oslo, noted the increasing challenge of evaluating climate policies due to their growing number. He stated that the findings assist decision-makers in identifying effective climate policies within their national contexts.
