New Zealand’s policies are grounded in scientific research, but some criticisms have emerged regarding the pace of implementation.

RANK 4: Germany — SCORE: 85/100
Germany, often heralded for its "Energiewende" (energy transition) policy, aims for a 65% reduction in emissions by 2030. The country derives about 42% of its energy from renewable sources, mostly wind and solar. However, Germany faces challenges with public acceptance of certain renewable projects and the lagging pace of phasing out coal. Adaptation strategies are present but often criticized for being reactive rather than proactive. Public engagement is encouraged, yet there are disparities in awareness levels across regions. The reliance on scientific advice is generally strong, though recent debates have emphasized a need for more timely implementation of recommendations.

RANK 5: United Kingdom — SCORE: 82/100
The UK has enshrined a legally binding commitment to reach net-zero emissions by 2050 and has made commendable progress, with a reduction of approximately 44% in emissions since 1990. About 40% of its energy is sourced from renewables, largely due to the expansion of offshore wind farms. The UK’s adaptation measures focus on flood defenses and urban resilience, but public understanding and involvement in climate issues could be enhanced. Policies are largely informed by scientific research, yet recent governmental shifts have raised concerns about the continuity of climate commitments.

RANK 6: China — SCORE: 78/100
China is the world's largest emitter of greenhouse gases but has set a target to achieve carbon neutrality by 2060. The country has invested heavily in renewable energy, leading globally in solar and wind capacity. Despite these investments, coal remains the dominant energy source, complicating emission reduction goals. Adaptation strategies are increasingly recognized as essential, particularly in response to severe air pollution and climate impacts. Public engagement is limited, with minimal transparency in policy formulation. While some policies are guided by scientific research, the overall execution varies significantly across regions.

RANK 7: United States — SCORE: 75/100
The United States has re-entered the Paris Agreement, pledging to cut emissions by 50-52% from 2005 levels by 2030. However, progress remains inconsistent across states, with policies frequently influenced by political dynamics. Approximately 20% of its electricity comes from renewable sources, with substantial potential for growth. Adaptation measures vary widely, reflecting a patchwork approach to climate resilience. Public engagement is often polarized, complicating unified action. While scientific research informs many policies, skepticism around climate science continues to hinder cohesive national strategies.

RANK 8: India — SCORE: 72/100
India is increasingly affected by climate change, yet its ambitious goals include a 33-35% reduction in emissions intensity by 2030 relative to 2005 levels. The country has made strides in solar energy deployment but still relies heavily on coal.
