As businesses consider the impacts of climate change on their long-term sustainability, it has remained difficult to measure such risks - until now. Future activities must consider physical impacts of climate change and the transition to a low-carbon economy. Transition Check allows corporate lenders and other financial institutions to quantify the impact of transition risk on their customers and corporate lending portfolios across a wide variety of climate scenarios. Transition Check applies the risk assessment methodology collaboratively developed by Oliver Wyman, the UNEP Finance Initiative (UNEP FI) and thirty-nine global financial institutions as part of UNEP FI’s Task-Force on Climate Related Financial Disclosures (TCFD) pilot program. That methodology is detailed in Extending Our Horizons, UNEP FI and Oliver Wyman’s joint whitepaper.
