Can you provide the report this is from?
This is connected to the Task Force for Climate Related Disclosure (TCFD). TCFD defines climate-related risk as either Physical or Transitional.
For physical risk, physical risk can either be defined as acute or chronic. Acute being weather as we know it, but with the increased ferocity of weather events that is expected to be realized as the climate changes. Chronic being connected to rising sea levels, changes in precipitation patterns, etc.
Transitional risk centers around identify those financial investments that may ultimately be stranded as the economy transitions from high- to low-carbon intensive.
TCFD is designed to assist financial institution with also identifying opportunities for sound financial investment in changing economy.
