Transition Check has now moved to an Excel-based implementation. The online tool may be updated in the future to reflect new scenarios, but at present, the Excel-based tool represents the latest scenario data.

Transition Check is a tool that takes a scenario-based approach for assessing transition risk and the potential impact of climate change on corporate lending portfolios within an overall framework consistent with the recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures (TCFD).

Transition Check represents the culmination of two years of collaboration between the UN Environment Programme - Finance Initiative (UNEP FI), Oliver Wyman Consulting, and dozens of UNEP FI member banks within UNEP FI’s TCFD pilot projects. The approach behind Transition Check was developed and validated in the first TCFD pilot project and detailed in the Extending Our Horizons report.

This methodology leverages climate scenarios from the Network for Greening the Financial System (NGFS) produced by globally renowned researchers such as the Potsdam Institute (PIK) and the International Institute for Applied Systems Analysis (IIASA). Scenario variables are then transformed into financially relevant impacts for a broad range of economic sectors and geographies. These financial impacts can then be used to produce portfolio level expected losses (EL), probabilities of defaults (PD), and losses given default (LGD) under each scenario. Transition Check provides financial institutions with a dynamic and user-friendly way to conduct transition risk assessments using this tested approach.

Transition Check is currently only accessible for institutions that are members of UNEP FI.
