Protein vs. Climate: What Functionally Equivalent Protein Actually Costs in Food and Emissions
Protein requirements are fixed by biology, but the climate cost of meeting them is not. Most diet–climate comparisons evaluate foods by calories, servings, or kilograms consumed. This analysis instead normalizes greenhouse gas emissions and food intake to functionally equivalent protein, revealing a set of unavoidable tradeoffs. By comparing food volume, emissions, digestibility, and access constraints…
