The Climate Change Performance Index ranks 58 countries across 15 indicators in four areas: emissions, efficiency, renewables, and climate policy.
The main areas covered are current emissions levels and development of emissions (30 percent of total score each), which covers CO2 emissions from various sources and sectors, as well as a target-performance comparison; renewable energy (10 percent of score), which emphasizes both the present share of renewables in the energy supply, and the future development of renewables; energy efficiency (10 percent of score), both the present level and the trend; and, lastly, climate policy (20 percent of score).

So far, no country has ranked in one of the top three slots – because no country is apparently performing well enough to meet the ideal carbon emissions targets.
These indices can help countries track their development while staying within the bounds of the biosphere.
