Northern Ireland Water

Does the core business genuinely avoid or reduce emissions, or build climate resilience? Share of revenue that is actually 'green'. Fossil-dependent models score low.

NI Water is the largest electricity consumer in Northern Ireland (~3% of total NI demand) and operates 2,398 sewage overflows without real-time discharge monitoring; while it is investing in renewable energy (solar at Dunore) and nature-based treatment, its wastewater leakage into waterways including Lough Neagh is a net-negative climate-resilience outcome, and 100% of NI river stretches fail 'good' ecological status partly due to sewage.

Credible, science-based targets (SBTi), a real net-zero plan with progress to date, and CDP disclosure — not just a dated press release.

NI Water has set a self-declared net-zero target for energy by 2030 and all emissions by 2040 against a 2020/21 baseline, but there is no evidence of SBTi validation, no CDP disclosure found in public records, and no independently verified interim progress reporting; the targets therefore score as aspirational pledges rather than credible science-based commitments.

Operational footprint, labour and social practices, and governance quality across the company's own operations and supply chain.

NI Water publicly acknowledges capital funding is insufficient to meet regulatory standards, its 2,398 sewage overflows lack real-time monitoring, wastewater treatment compliance was found significantly lower in unannounced inspections than in pre-announced tests, and an independent panel recommended ending the company's existing protections from pollution fines — all pointing to material ESG governance gaps.

Quality of disclosure, independent third-party verification, and how much hard data backs the company's claims.

Unlike privatised English water companies, NI Water publishes limited public data on sewage discharge volumes or environmental fines; there is no CDP submission found, no SBTi-registered commitment, and Surfers Against Sewage notes that despite mapping overflow locations, NI Water provides no data on discharge frequency due to lack of monitoring infrastructure.

Controversies, litigation, pollution, fossil-fuel lobbying, conflict-zone involvement and governance scandals. Higher means cleaner.

NI Water was responsible for 480 confirmed water pollution incidents between 2020 and 2024 (over 11% of all NI incidents), contributing to the Lough Neagh ecological crisis that drew international attention in 2023 when algae blooms were visible from space; judicial review proceedings are ongoing against the regulator over wastewater governance failures, and an independent environmental panel has called for the company's fine protections to end.
