It is a scoring system designed by the Germanwatch - a non-profit, non-governmental organisation (NGO) based in Bonn, Germany.It was first published in 2005 and an updated version is presented at the UN Climate Change Conference annually.
The index aims to improve transparency in international climate policy by assessing and comparing the climate protection performance of 63 nations and the European Union (EU), which account for more than 90% of global greenhouse gas (GHG) emissions.
Ranking
The report leaves the first three spots empty because no country did well enough in all index categories to earn a very high overall grade. Denmark is ranked fourth, followed by Sweden and Chile.
China, the world's leading polluter, dropped 13 spots to 51st in this year's CCPI and received an overall very-low grade due to plans for new coal-fired power plants.
The US climbed three places to 52nd place. The weakest performers were Iran (63rd), Saudi Arabia (62nd), and Kazakhstan (61st)
India specific highlights in the CCPI 2023:
Because of its low emissions and rising usage of renewable energy, India climbed two spots to 8th place out of 63 countries in the recently released Climate Change Performance Index (CCPI) 2023.
Important step taken by India
Since the last CCPI, India has updated its Nationally Determined Contribution (NDC) - national plans to limit global temperature rise to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius in accordance with the Paris Agreement.
India also announced a net-zero (achieving a balance between the GHGs put into the atmosphere and those taken out) target for 2070.
