SSE plc

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.

SSE operates ~5 GW of renewables and is targeting 9 GW by 2027, plus enables >20 GW of third-party renewable connections via SSEN Transmission—genuine systemic impact—but ~60% of installed generation capacity by MW remains fossil-gas, and a new gas+CCS plant is proposed at Peterhead, materially offsetting the renewable story.

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

SSE holds SBTi-validated near-term targets aligned to the 1.5°C power-sector pathway (80% scope 1 intensity cut and 72.5% absolute scope 1&2 reduction by 2030, both from a 2017/18 base), scope 1&2 net-zero by 2040 and scope 3 by 2050, with an annual shareholder 'say on climate' vote that received 98.2% approval in 2024—among the most robust target frameworks in the UK utility sector.

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

SSE publishes a detailed Just Transition Strategy, ties executive pay to GHG reduction KPIs, is committed to EV100 for its fleet, has begun TNFD-aligned nature disclosures across 125 assets, and maintains a Fairwork guarantee; controversy around forced prepayment meters and fuel-poverty practices moderately depress the social pillar.

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

SSE's sustainability data is subject to independent limited assurance by EY, it discloses to CDP (most recently CDP Climate A- for 2024/25), participates in the UK Transition Plan Taskforce sandbox, and publishes a detailed annual Net Zero Transition Plan with scenario modelling—disclosure quality is among the best in UK utilities, though limited assurance (not reasonable assurance) and a lack of full Scope 3 audit temper the score.

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

SSE faced AGM protests in both 2024 and 2025 over its Peterhead gas-CCS project (Scotland's single largest point-source polluter), was implicated in questionable carbon-credit purchases described by investigators as likely ineffective offsets, and drew criticism for forcing prepayment meters on households in energy debt—none rise to criminal sanction but collectively represent a pattern of reputational and ethical risk that investors must weigh.
