The Environmental Audit Committee scrutinises the government's environmental policies, strategies and delivery of environmental protection across departments and agencies. Operating as a House of Commons select committee, it takes oral evidence from government officials, regulators and external witnesses to examine environmental governance and outcomes. Recent inquiries have centred on air quality and its health impacts, with the committee examining nitrogen pollution levels in England and wider air quality policy effects. The committee has scrutinised ancient woodlands policy through evidence panels and investigated peatlands management with testimony from the Department for Environment, Food and Rural Affairs, Natural England and the Environment Agency. It has also examined per- and polyfluoroalkyl substances (PFAS) regulation with input from regulators and DEFRA, and assessed progress on the Environmental Improvement Plan 2025 across farming, ecology and air quality priorities. The committee received evidence from the Office for Environmental Protection on environmental targets and land and sea use objectives as part of its oversight of long-term environmental accountability.

The Committee scrutinised how HM Treasury is pricing climate and nature risk, whether the OBR can reflect adaptation and resilience spending, and how fiscal rules and public investment shape the net zero transition. Witnesses agreed climate damages pose major long-term fiscal risks, but stressed wide uncertainty and the need for transparent scenarios. They also argued Treasury support is uneven: strong on climate mitigation frameworks and market signals such as contracts for difference and the ZEV mandate, but weaker on nature, adaptation, regional delivery and skills. The Transition Finance Council witnesses pressed for government-backed transition finance instruments, a transition finance lab, clearer fiduciary duty, and more capital and mandate support for the National Wealth Fund. The final panel argued Treasury should combine regulation, public co-investment and market design, warning that policy inconsistency and weakened consensus are deterring private capital and raising consumer costs.

The committee scrutinised the Government’s biodiversity national security assessment, its publication status, and how it is shaping cross-government action on climate, food, water, security and international diplomacy ahead of COP17. Ministers defended the assessment as a cross-government publication and said it is already influencing taskforces, international climate finance, forest finance, and nature diplomacy, while also acknowledging limits on public finance and that some nature priorities are still being determined. Members pressed on redactions, access to the full report, DEFRA’s role in security coordination, overseas aid cuts, and whether the UK will commit to major international forest and biodiversity finance mechanisms.

The Committee scrutinised the UK’s push to expand data centres, focusing on whether growth can be compatible with climate, water and local planning constraints. Witnesses broadly supported domestic expansion for AI sovereignty, economic growth and grid flexibility, but repeatedly warned that the sector needs clearer planning, better data, stronger sustainability criteria and more careful siting. Key themes included the risk of gas- and diesel-backed capacity during grid connection delays, the possibility of higher electricity prices and socialised grid reinforcement costs, water stress in south-east England, and the need to capture waste heat through heat networks and zoned planning. Witnesses also pressed for more transparent lifecycle emissions accounting, hourly matching, public mapping of land and grid capacity, and stronger local community involvement in decisions.
17 Jun 2026
The Committee examined how HM Treasury’s spending, tax, appraisal and fiscal rules shape delivery of climate and nature goals. Witnesses from academia, NGOs and think tanks argued that the Treasury has strong tools and some recent improvements, but still undervalues nature, underuses long-term risk/opportunity analysis, and lacks transparency in how environmental considerations affect decisions. They highlighted the need for biodiversity pricing, natural capital accounting, a nature risk assessment, a green taxonomy, stronger public investment and transition planning, and more consistent political leadership to turn existing frameworks into real spending and market signals.

The Committee scrutinised the Government’s Carbon Budget 7 pathway, especially whether the zero-emission vehicle mandate would be weakened, what the main delivery risks are, and how far the Government is relying on technology rather than behaviour change. Ministers defended the review of the ZEV mandate but insisted electrification remains central, said the CB7 plan will be a stand-alone cross-government document published as soon as reasonably practicable after Parliament sets the target, and argued the pathway is credible, modest and investment-led. They also resisted calls for extra risk registers and a cross-government delivery framework, while acknowledging challenges around retrofit, agriculture, grid capacity, local authority delivery, energy price reform, and the role of greenhouse gas removals and aviation credits.
10 Jun 2026
The Committee scrutinised the sustainability of UK data centres, including growth in AI-related demand, grid connection constraints, water use, carbon emissions, waste heat, and local planning impacts. Witnesses from AWS, Crown Hosting, Ada Lovelace, techUK, nLighten and Global Action Plan disagreed sharply on whether demand forecasts are being exaggerated, whether efficiency gains will reduce total impacts, and whether voluntary sustainability commitments are enough. The session surfaced calls for transparent, legally binding community and environmental commitments, better national planning and carbon-budget accounting, and stronger incentives for waste heat reuse and genuinely new clean energy supply.
