Global Switch reported 182,973 tCO2e on market-based figures across Scopes 1, 2 and 3 in 2025, up 15% on 2024. It says 88% of its purchased electricity is renewable, down from 91%, resting on PPAs and certificates with no split published. Its two published contracts start in 2026 and 2027, so neither supplied 2025. Its verifier could not review the 2025 certificates, so its market-based conclusion is conditional. SBTi lists Scope 1 and 2 down 42% by 2030 from 2023, but they stand at 71,227 t against a 48,533 t baseline. A London council officer recommended against 32 extra generators over air quality; the committee granted permission.
