Grantham: 7 of 9 Reform councils cut climate

The LSE Grantham Research Institute found seven of nine 2025 Reform-led councils scrapped climate targets, three rescinded Climate Emergency Declarations, and five put climate-change-denial language into formal documents; eight 2026 councils already softened climate language in week one.

Key takeaway

Rescinding climate declarations without a written replacement policy opens a second administrative-law front behind the LGR judicial reviews.

The LSE Grantham Research Institute published a study finding seven of nine 2025 Reform-led councils scrapped climate targets after May 2025, with three rescinding Climate Emergency Declarations entirely and five putting climate-change-denial language into formal documents 1. The 2026 cohort's first-week softening of climate language at eight Reform-controlled councils follows the 2025 pattern with near-perfect fidelity. Grantham's authors predict "the majority" of the 14 new Reform-led authorities will replicate the rescission pattern.

The administrative-law question sits inside this fact. Councils that strip climate targets without publishing a written replacement policy framework leave themselves open under the policy-framework-consistency tests in the Local Government Act 1972 and the Public Sector Equality Duty. A council that has formally declared a Climate Emergency and then rescinded that declaration without producing a successor policy carries the burden of demonstrating it had "due regard" to the equality impacts of the reversal, the same Public Sector Equality Duty test that anchors the Essex LGR challenge. The LGR judicial reviews will land in the Administrative Court first; climate-policy challenges, if they come, will follow later in the year.

Most peer-reviewed climate-policy research runs at national-government level; comparable subnational data reaches print through case studies rather than systematic samples. Grantham's five-of-nine climate-denial finding is therefore the first quantitative evidence of language drift in formal council documents, which courts can weigh under the reasonableness tests of judicial review. The 2025 baseline plus the 2026 first-week replication makes the prediction quantitatively grounded rather than rhetorically asserted.

Deep Analysis

In plain English

Many councils across England declared a Climate Emergency in 2018 and 2019, officially committing to reduce carbon emissions and factor climate into council decisions. The LSE's Grantham Research Institute studied what happened when Reform UK took control of nine councils in 2025: seven of them scrapped their climate targets. Three formally cancelled their Climate Emergency Declarations. Five put language into official documents suggesting they do not accept that climate change is a serious problem. Now that Reform has won around 14 more councils in 2026, Grantham researchers predict the same pattern will repeat. Eight of those 14 new councils have already softened their climate language in the first week. There is a legal question here: councils that cancel their climate commitments without explaining what replaces them may be open to legal challenges. Courts have previously found that councils must think carefully about the impact of policy changes on vulnerable groups, and that applies to environmental commitments too.

Deep Analysis
Root Causes

Grantham's 7-of-9 finding captures a governing-party dynamic the briefing body's administrative-law framing does not fully explain. Reform's local council platforms in 2025 and 2026 explicitly promised to reverse 'climate alarmism' and cut spending on sustainability officers and environmental commitments. Elected Reform councillors arrive with a mandate to rescind.

The problem is that most Council Executives have integrated climate commitments into procurement frameworks, asset management plans, and capital programme appraisals over the previous three to five years. Reversing the declaration is quick; unwinding the downstream commitments in those documents requires either the officers' cooperation or a formal decision on each document, each of which could be challenged individually.

The five councils that put denial language into formal documents crossed a distinct line. Formal council documents that list 'climate change is not proven' as a policy rationale become part of the documentary record a planning inspector or Administrative Court judge reviews when assessing whether a council had due regard to environmental considerations in a planning or service decision.

That language does not need to trigger a standalone climate challenge to damage the council in an unrelated planning judicial review.

What could happen next?
  • Risk

    Councils that placed climate-denial language into formal documents face a more defensible litigation target than rescission-only councils, because formal documents carry legal weight in planning and procurement judicial reviews regardless of whether a standalone climate challenge is brought.

    Medium term · Assessed
  • Consequence

    Grantham's 78% rescission rate for the 2025 cohort, replicated at eight of 14 in the first week of the 2026 cohort, gives claimants a documented pattern of systematic policy reversal rather than individual council decisions, which provides a stronger framing for any future group litigation.

    Medium term · Assessed
  • Precedent

    If a successful climate-policy judicial review against any single Reform council establishes that Climate Emergency Declarations require a written successor framework on rescission, a procedural requirement would apply to all 20-plus Reform councils that have rescinded or plan to rescind.

Causes and effects
This Event
Grantham: 7 of 9 Reform councils cut climate
Councils that strip targets without a written replacement policy framework risk administrative-law challenge under the policy-consistency tests.
Different Perspectives
Welsh Government (Plaid Cymru under Rhun ap Iorwerth)
Welsh Government (Plaid Cymru under Rhun ap Iorwerth)
Plaid's Cardiff minority government relies on Green confidence-and-supply with no written agreement, the same arrangement that collapsed in Scotland in 2023. Green Westminster polling fell from 17% to 15% in two weeks as Greens took governing responsibility; whether that deflation reaches Cardiff is the near-term test for ap Iorwerth's majority.
Reform-run English county councils (Essex, Suffolk, Norfolk)
Reform-run English county councils (Essex, Suffolk, Norfolk)
Essex named a City-trained efficiency lead over a budget where statute has already committed roughly 98% of spend; Suffolk simultaneously issued a pre-action letter against the reorganisation that will dissolve it. Reform-controlled authorities are spending public money on litigation their own sector lawyers expect to fail while their DOGE units face statutory constraints they cannot override.
Scottish Government (SNP under John Swinney)
Scottish Government (SNP under John Swinney)
Swinney rested the 72-55 Holyrood mandate on the combined SNP-Green bloc rather than his own party's 58 seats, seven short of the trigger he named; he has publicly conceded he has no plan if Westminster holds its veto. The constitutional argument is made; the enforcement route does not exist.
UK Government (MHCLG and Downing Street)
UK Government (MHCLG and Downing Street)
MHCLG has until 12 June to respond to Suffolk's pre-action letter and faces three further counties at the same stage; Downing Street rejected Holyrood's Section 30 demand as a spokesperson lobby line rather than a written statement, declining to open formal inter-governmental correspondence. Both decisions compress Reform's two main legal challenges into the same two-week window.
UK Government (Labour)
UK Government (Labour)
Westminster framed the youth justice transfer as a culmination of prior work rather than a precedent, refused a Section 30 order before the request arrived, and omitted both the Representation of the People Bill and any Wales Bill from the 13 May King's Speech. Starmer is described as open to a devolved-leaders summit in June.
Reform UK
Reform UK
Essex, Norfolk and Suffolk filed pre-action protocol letters framing their LGR challenge as mandate-consistent, while 22 Reform councillors departed in 14 days at an annualised rate nearly three times the 10 percent projection. Richard Tice defended the Harborne 5 million pound gift as unconditional, with no acknowledgement of Farage's two contradictory accounts on record.
