Scope 1 emissions 2,700 tonnes CO₂e; Scope 2 market-based ~900 tonnes CO₂e (FY25). 82% cumulative reduction from 2019 baseline. Methodology documented in GHG Protocol-aligned Carbon Reporting Principles. Multi-year tracking covers all offices and owned data centres. SECR disclosure included. No external assurance statement confirmed.

Scope 3: 219,100 tonnes CO₂e (FY25), 98% of total. Methodology upgraded in 2023 from spend-based to include actual supplier emissions. Seven categories quantified. Cloud data centres captured. Supplier target: 78% of spend-weighted suppliers to hold SBTi-validated targets by 2029; 32% already set targets (FY25). Not externally assured.

Scope 1+2 market-based fell 82% absolute since 2019, including 30% in FY25 alone. Scope 3 increased from ~180,600 tonnes (FY23 restated) to 219,100 tonnes (FY25) due to methodology upgrades and acquisitions, but also real growth in cloud and travel. Mixed trajectory capped at 5.

87% of electricity consumption backed by renewable energy or RECs (FY25, up from 75% in FY24). Data centres in North America, UK, Ireland have REC-backed electricity since 2022. On-site solar at Brazil and India sites. Reliance on unbundled RECs rather than PPAs or new-build additionality caps score at 6.

TNFD LEAP assessment completed. One small South Africa office in biodiversity risk area. Company assessed as not dependent on biodiversity and not materially at risk. No quantified nature footprint or restoration commitments beyond screening. Environmental policy published.

Service business with limited physical consumption. FY25 waste assumptions: 55% recycled, 24% landfilled, 21% incinerated (where site data unavailable). Single-use plastics reduction mentioned. Supply chain includes sustainability clauses. No closed-loop or circular economy programme with measurable targets.

Two owned data centres use water for closed-loop cooling systems. Other data centres use no water. Water data available only since 2023. No emissions to water reported (assessed not material). WRI Water Risk Atlas used to assess operational sites. No reduction targets or watershed engagement.

SBTi-validated near-term target: 50% absolute Scope 1+2 reduction by 2030 (2019 baseline, 1.5°C aligned). SBTi-validated Scope 3 supplier target: 78% spend-weighted targets by 2029 (well-below-2°C). Net Zero Transition Plan aligned with UK TPT framework. FY25 cumulative S1+2 reduction 82% exceeds 50% target. No validated long-term net-zero SBTi target.

Annual Sustainability Performance Data document, TCFD index, CDP A- score (2024), SASB alignment. Board oversight via Audit and Group Operating Committees. Dedicated sustainability function. SECR reporter. Supplier Engagement Rating A (Leaders Board). No executive compensation linkage to sustainability confirmed; no mission-lock structure.

No environmental controversies or greenwashing rulings identified. No fossil fuel exposure. However: (1) Dutch DPA fine €2.7M (2025) for GDPR violations—unlawful collection and use of personal data from Dutch residents; Experian acknowledged, did not appeal. (2) UK ICO enforcement notice following two-year investigation into data broking practices. Pattern across two jurisdictions on data governance.
