Google's latest environmental report shows its carbon footprint rose 18% in 2025, now 81% above its 2019 baseline. The company says AI infrastructure is expanding faster than the grid can decarbonize. Scope 3 emissions, which make up 80% of Google's total, jumped 25% due to hardware manufacturing and data center construction. Scope 1 emissions also rose 20% from backup generator fuel use at new data centers. Google signed over 12 GW of new clean energy in 2025 but its carbon-free energy average stayed flat at 65% because electricity use grew 37%. The company still aims for net-zero by 2030 but acknowledges the path is not linear. It plans to start counting carbon removal credits in 2030 and has already contracted 1.38 million tons of CO2 removal and over 1 million tons of superpollutant credits.

Google's 2025 report shows emissions up 18% YoY and 81% above 2019 baseline. Scope 3 is the big driver: hardware manufacturing and data center construction. They signed 12 GW of clean energy but carbon-free energy share barely moved because electricity use jumped 37%.

The 81% increase from 2019 baseline is rough for a company with a 2030 net-zero target. They claim without their decarbonization efforts the footprint would be 5x larger, but that's a counterfactual you can't verify. Scope 3 is 80% of total and still climbing.

The flat carbon-free energy share (65% vs 66%) despite 12 GW of new PPAs tells you everything about how fast load is growing. They are building data centers faster than new renewables can interconnect. That gap is the real story for anyone watching grid constraints.

Google stopped using carbon credits in 2023 after claiming neutrality for 15 years. Now they say they will start counting removal credits in 2030. They have contracted 1.38 million tons of CO2 removal so far. That shift in methodology is worth watching.

The report says without their decarbonization efforts the footprint would be 5x larger. That is a hard claim to verify. Also notable: they exclude some Alphabet purchases from scope 3 and use SAF certificates for air freight. The methodology matters for comparability.

They missed their 2025 recycled plastic target (48% vs 50%) and food waste diversion target (84% vs 100%). Those are small compared to the emissions story but show that even operational sustainability goals are slipping when the core business is growing fast.
