Critical habitat
Definition
In international finance practice, critical habitat refers to areas with high biodiversity importance, defined by IFC Performance Standard 6 criteria including habitat of significant importance to critically endangered or endangered species, endemic or restricted-range species, migratory or congregatory species, highly threatened or unique ecosystems, and key evolutionary processes. Projects in critical habitat must demonstrate no measurable adverse impacts and achieve net gains for the qualifying biodiversity values.

Overview
What it means
A screening concept that escalates requirements for projects touching the most sensitive biodiversity — distinct from legally designated protected areas.
How it is used
Lenders applying the IFC Performance Standards or the Equator Principles require critical-habitat assessments; research suggests roughly a tenth of the terrestrial realm may qualify, making early screening material for project siting.
Why it matters
Critical habitat is the operational test that determines whether finance can flow to projects in biodiverse areas, and under what conditions.
