Google published its 2026 Environmental Report — its 11th annual report, covering 2025 performance — on 30 June 2026. It is one of the most detailed corporate sustainability disclosures in the technology sector, and this year it tells a candid story: strong progress on clean energy and efficiency, set against rapidly rising demand driven by AI. Here is our review of what has been done well, and where there is room to improve.
Key Numbers at a Glance (2025)
| Indicator | 2025 performance |
|---|---|
| Electricity consumption | Up 37% year-on-year — the largest load growth in Google’s history |
| Total greenhouse gas emissions | Up around 18% year-on-year, driven mainly by the supply chain |
| Operational emissions (Scope 1 + market-based Scope 2) | Down 2% year-on-year |
| Supply chain emissions | Up 25% year-on-year, largely from manufacturing AI hardware |
| Emissions intensity | Emissions per GWh down 47% compared with 2019 |
| Clean energy | Over 12 GW of new clean energy contracts signed in 2025; 100% annual renewable energy match for the ninth year |
| Data centre efficiency | Fleet-wide PUE of 1.09 |
| Water | Consumption of 10.9 billion gallons (up 34%); about 78% replenished against a 120% goal for 2030 |
| Waste and circularity | 88% of data centre operational waste diverted from landfill; over 7.5 million components harvested for reuse |
What Has Been Done Well
- Transparency about difficulty: the report openly acknowledges that reaching its climate goals is “getting harder” and that the path is non-linear — a refreshing contrast to purely promotional reporting.
- Decoupling through efficiency: emissions per unit of electricity have fallen sharply since 2019, and data centre efficiency remains industry-leading.
- Scale of clean energy procurement: a record volume of new clean energy contracts, supporting new capacity on the grid.
- Operational emissions held down: despite a 37% jump in electricity use, Scope 1 and market-based Scope 2 emissions still fell.
- Circularity in hardware: high waste diversion and large-scale reuse of server components.
- Supply chain visibility: the report identifies the main sources of rising emissions — hardware manufacturing, data centre construction and carbon-intensive grids in Asia-Pacific supply chains — rather than hiding them.
What There Is to Improve
- Absolute emissions are rising: efficiency gains are being outpaced by growth. Credible pathways to absolute reductions — not just intensity improvements — will be essential to meet net-zero commitments.
- Scope 3 is the real battleground: with supply chain emissions up 25%, stronger supplier requirements, clean-energy support for manufacturing partners and low-carbon construction materials need to move faster.
- Water replenishment gap: replenishment of about 78% against a 120% goal, while consumption grew 34%, shows water is becoming as material as carbon. More site-level disclosure for water-stressed locations would build trust.
- Annual matching vs. hourly carbon-free energy: a 100% annual renewable match is not the same as running on carbon-free electricity every hour. Clear progress reporting on round-the-clock carbon-free energy is key.
- Reliance on “avoided” and “enabled” emissions: estimates of emissions avoided through efficiency, or enabled by Google’s products for others, are useful context but are based on counterfactuals. They should be clearly separated from, and never offset against, the company’s own inventory.
- AI-specific transparency: as AI drives most of the growth, more granular data on the energy, water and carbon footprint of AI workloads would help stakeholders judge the trade-offs.
Lessons for Organisations in India and the GCC
- Measure Scope 3 early: as BRSR Core and value-chain disclosures expand, supplier emissions data will become essential. ISO 14064-1 provides a sound framework.
- Report honestly: acknowledging challenges builds more credibility than selective reporting.
- Treat water as a material issue: especially in water-stressed regions like Tamil Nadu and the Gulf.
- Use management systems to drive delivery: ISO 14001:2026 (with its life cycle perspective), ISO 50001 for energy and ISO/UNDP 53001 for SDGs turn commitments into objectives, controls and evidence.
- Separate targets from offsets: keep a clear line between your own reductions and claims about avoided emissions or credits.
