A comprehensive investor guide to scenario-based methods for climate risk assessment, in response to the TCFD May 2019 Changing Course | | 1 Twenty institutional investors from eleven countries, convened by UNEP FI and supported by Carbon Delta, have worked throughout 2018–2019 to analyse, evaluate, and test, state- of-the-art methodologies to enable 1.5°C, 2°C, and 3°C scenario-based analysis of their portfolios in line with the recommendations of the FSB’s Task Force on Climate-related Financial Disclosures (TCFD). The outputs and conclusions of this Pilot are captured in the following report and aim to enhance the understanding and ease adoption of the TCFD recommendations by the wider investment industry.
