OVO Energy sustainability score: 42/100

OVO reports Scope 1 and 2 emissions using GHG Protocol methodology. 2023 total: ~3,434 tonnes CO₂e. Fleet is 98% EV. Office energy fully renewable. Detailed basis of preparation document published. Third-party verification status not clearly confirmed.

OVO reports Scope 3 at ~9.78 million tonnes CO₂e (2023), dominated by gas combustion (Category 11). Uses location-based methodology. Multiple categories quantified with stated methods. Scope 3 renewables target is 76.8% per MWh (intensity), not absolute reduction.

OVO claims 38% total footprint reduction and 50% operational emissions cut from 2018 baseline. However, Scope 3 target for sold electricity is intensity-based, not absolute. Dominant 9.8Mt gas supply emissions remain unabated. Scope 1 & 2 location-based emissions increased 7% in one period. Capped due to intensity targets.

OVO offices use 100% renewable electricity; 98% van fleet electric. However, only ~30% of customer energy sourced from renewables in 2023. Company moved away from REGO certificates in 2023 (acknowledging greenwashing) and signed PPAs with Ørsted and Eneco. Renewable sourcing remains minority of supply mix.
