ESG rating
An assessment that scores an entity, security or fund on selected ESG risks, practices or performance using a provider’s methodology.
Key Matters and Considerations in ESG
Ratings can differ substantially because of scope, data, weights and whether they measure risk, impact or both; users should understand the methodology rather than rely on a single score.
