The climate change performance index: background and methodology

Abstract

Evaluation of the CCPI Since 2005, the Climate Change Performance Index has been contributing to a clearer understanding of national and international climate policy. It is an important tool towards the various initial positions and interests as well as kept and broken promises of the numerous countries in a world which is facing the challenge to reduce the causes of a dangerous climate change. To further demonstrate existing measures more accurately and encourage steps towards an effective climate policy, the index’ methodology has been evaluated after its seventh edition. The evaluation process was carried out in order to reorganise the underlying data, to find a method to integrate newly available deforestation data, to better capture recent political movements and to develop an approach which is more focused on mitigation solutions regarding climate change performance. Our world is characterized by fast-moving geopolitical and natural changes and our goal was to increase the sensitivity of the CCPI towards these changes. One of the biggest challenges for the creation of a country-related composite index is the vast diversity of countries regarding geographical pre-conditions, historic responsibilities and economic capabilities. A second goal of the evaluation of the CCPI was, therefore, to better balance the subsets of indicators for a more equitable result in terms of these country specifics. A major step forward has been made with the integration of data on emissions from deforestation. We are now able to present a more complete view on anthropogenic impacts on the world’s climate. With an updated weighting and categorization of indicators we can track changes in climate change performance more immediately and at the same time increase the equity balance of the CCPI.
