CDP-WWF Temperature Scoring Methodology Overview

The CDP-WWF Temperature Scoring Methodology is a technical report that provides an open-source method for translating corporate greenhouse gas (GHG) emissions reduction targets into temperature scores. This methodology is designed for use by financial institutions and large corporations to assess the impact of their Scope 3 emissions on global warming. It outlines a three-step protocol that includes benchmark creation, company-level assessment, and portfolio scoring. The report details how to compute temperature scores using regression models based on the latest climate science, specifically the IPCC AR6 data. It also addresses the challenges of comparing corporate targets and the need for transparency in emissions reduction efforts. This updated version 1.5 incorporates the latest climate benchmarks and improves upon previous methodologies to ensure relevance and effectiveness. The report is intended to support climate change mitigation efforts and facilitate the alignment of corporate strategies with long-term temperature goals.
