Freddie Mac publishes no emissions data for its operations or its mortgage book, and no reduction targets; its last sustainability report covered 2023 and its ESG web page was removed in 2025. Members of Congress and NGOs have criticised the government-sponsored enterprises' limited climate-risk action, and the Richmond Fed estimates more than 23 million Fannie Mae and Freddie Mac loans sit in ZIP codes at risk of future flooding.
Freddie Mac scores 22/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.

Its three lowest-scoring questions, and what the evidence didn't show.
Freddie Mac's 2023 Sustainability Report marks Scope 1 and 2 GHG emissions as 'Not disclosed' in its TCFD Index.
Freddie Mac publishes no Scope 3 inventory or PCAF-basis financed-emissions figure for its mortgage book.
No year-on-year absolute emissions series exists for operations or financed mortgages, because Freddie Mac has never published Scope 1, 2, or 3 figures.
