Evidence Summary
- Meta-analyses and large datasets find plant-forward diets lower GHG footprints.
- Even partial shifts (flexitarian) can yield meaningful reductions. Evidence quality: High Limitations / nuance: Regional contexts matter; some low-income regions need nutrition-sensitive approaches. Bottom line: Climate benefits of plant-forward diets are robust across methods.
