Why it's on ClimateTicker

Yorkshire Water is a regulated water and sewerage utility with genuine climate adaptation relevance — operating critical infrastructure under intensifying flood, drought, and heat stress — and a stated 2030 net-zero operational target aligned with the UK water sector pledge. However, the company is simultaneously one of England's worst sewage polluters, rated 'lagging behind' by Ofwat, fined £40m for systematic wastewater failures, and responsible for 68,164 sewage spills in 2024 alone, making its green marketing deeply at odds with its on-the-ground environmental record. Investors should treat sustainability claims with significant scepticism until pollution performance improves materially.

laggardYorkshire Water earns regulated revenue by providing water supply and wastewater/sewerage services to approximately 5.2 million customers and 140,000 businesses in the Yorkshire region, with tariffs and investment levels set by Ofwat every five years under the AMP price-control framework.
