It is compiled by three environmental non-governmental organisations – German watch, New Climate Institute and the Climate Action Network.
It is an independent monitoring tool for tracking the climate protection performance of the European Union and 59 countries.
Together the European Union and 59 countries in the CCPI 2023 account for more than 92% of the greenhouse gas (GHG) emissions in the world.
The rankings are based on how well the countries are doing to halve their emissions by 2030.
The report leaves the first 3 places empty as "no country performed well enough in all index categories to achieve an overall very high rating".
It puts Denmark in fourth place, followed by Sweden and Chile.
Iran, Saudi Arabia and Kazakhstan fared the worst.
In the CCPI 2023, India rose two spots to rank 8th out of 63, due to its low emissions and the increasing use of renewable energy.
The report said India is "on track" to meet its 2030 emissions targets.
However, the renewable energy pathway is not on track for the 2030 target.
India earned a high rating in the GHG Emissions and Energy Use categories, while it got a medium rating in Climate Policy and Renewable Energy sections.
Since the last CCPI, India has updated its Nationally Determined Contribution (NDC) and announced a net-zero target for 2070.
The report noted that India is among the nine countries responsible for 90% of global coal production and it also plans to increase its oil, gas, and oil production by more than 5% by 2030.
Since the last Climate Change Performance Index, India has updated its Nationally Determined Contribution (NDC) and has also announced a net-zero target for 2070.
Net Zero means achieving the balance between the greenhouse gases put into the atmosphere and those taken out.
