The Climate Change Performance Index (CCPI) is an independent monitoring tool for tracking countries' climate protection performance. It aims to enhance transparency in international climate politics and enables comparison of climate protection efforts and progress made by individual countries. This publication explains how the CCPI 2020 is calculated. Furthermore, it lists the literature and data sources used for these calculations.

The climate change performance is assessed in four categories:

  1. "GHG Emissions" (40% of overall score)
  2.  "Renewable Energy" (20% of overall score)
  3. "Energy Use" (20% of overall score)
  4. "Climate Policy" (20% of overall score)

A country's performance in each of the categories 1-3 is defined by its performance regarding four different equally weighted indicators, reflecting four different dimensions of the category: "Current Level", "Past Trend (5-year trend)", "2°C-Compatibility of the Current Level" and the "2°C-Compatibility of 2030 Target". These twelve indicators are complemented by two indicators under the category "Climate Policy", measuring the country's performance regarding its national climate policy framework and implementation as well as regarding international climate diplomacy.

Figure 1 gives an overview of the composition and weighting of the four categories and 14 indicators defining a country's overall score in the CCPI. For details on the constitution of a country's scoring, please see chapter 3 "Calculation and Results".
