Chart: Google’s 2025 emissions, year over year. Total up 18 percent; operations down 2 percent; value chain up 25 percent.
Total is Google’s ambition-based footprint, the ≈14.5 Mt CO₂e it counts toward its climate targets. Operations covers Scope 1 plus market-based Scope 2, the categories Google runs directly; value chain is Scope 3 (chips, steel, cement, construction), now about 80% of the total. Secondary coverage citing “+25%” is reporting Scope 3 growth, not the total. Source: Google 2026 Environmental Report (June 30, 2026). Read Searchlight 017 →

Research in progress and program context

HSI Searchlight analysis on hyperscaler net-zero commitments and the definitions underneath them. Forthcoming Research Briefs on energy and compute demand and on long-horizon institutional risk, and a forthcoming Horizon Scan on cascade risk across technology, climate, and governance.

Outputs are in scoping and drafting. See the research agenda for current work under this program.
