In 2017, the methodology of the Climate Change Performance Index (CCPI ) was revised to fully incorporate the 2015 Paris Agreement, a milestone in inter- national climate negotiations with the goal to limit global warming to well below 2°C or even to 1.5°C.
Since then, the CCPI includes an assessment of the well-below 2°C compatibility of countries’ current performances and their own targets (as formulated in their Nationally Determined Contributions, or NDCs).
Within the quantitative index cate- gories – “GHG Emissions”, “Renewable Energy” and “Energy Use” – current performance and the respective 2030 target are evaluated in relation to their country-specific well- below-2°C pathway. For the well-below-2°C pathways, ambitious benchmarks are set for each category, guided by the long-term goals of the Paris Agreement.
The three benchmarks are: nearly zero GHG emissions (taking into account country-specific pathways, which give develop- ing countries more time to reach this goal); 100% energy from renewable sources; and keeping to today’s average global energy use per capita levels and not increasing beyond.
The CCPI compares where countries actually are today with where they should be to meet the ambitious benchmarks. Following a similar logic, the CCPI evaluates the countries’ own 2030 targets by comparing these to the same benchmarks.
