London Mayor Concedes 2030 Net-Zero Target Unlikely
5/30/2026, 8:04:12 PM
Background: Ambitious 2030 Pledge vs National 2050 Target
Sir Sadiq Khan pledged in 2020 to achieve net-zero carbon emissions for London by 2030, a target that exceeds the UK’s national 2050 deadline. The plan has relied on the Ultra-Low Emission Zone (ULEZ) and bus electrification. The pledge, made six years ago, predates the 2025-2026 Spending Review that later introduced an integrated settlement for London.
Key Figures & Institutional Landscape
Mayor Sir Sadiq Khan leads the Greater London Authority (GLA), overseeing Transport for London (TfL), the London Fire Brigade (LFB), the police and the NHS, all of which he can influence through procurement. Green Party Assembly member Zack Polanski raised concerns about siloed climate actions. The Ministry of Housing, Communities and Local Government was contacted for comment.
Progress Measures and Remaining Barriers
ULEZ and bus electrification have cut emissions, and TfL and LFB remain on track to meet their own targets. The mayor says lack of direct control over the fossil-fuel-dependent electricity grid prevents London from hitting net-zero by 2030. He also stresses that retrofitting buildings is essential. The integrated settlement for 2026-2029 pools funding but does not grant grid authority.
Official Statements & Responses
The mayor argued that public-sector procurement can reshape the energy market and called for a city-wide retrofitting programme to lower bills. Polanski described the mayor’s actions as “siloed” and urged a non-negotiable 2030 target. The ministry offered no comment.
Criticism & Opposition
Polanski criticised the fragmented funding approach, calling the mayor’s criticism “fair” and emphasizing that climate science does not accommodate political delays. He urged the government to support cities with investment to achieve cheaper energy, cooler homes and a non-negotiable 2030 target.
Verbatim Quotes
- “The funding comes from different pots of money, it's frustrating,” — Sir Sadiq Khan, Mayor of London
- “If we had an integrated settlement, monies devolved to London in one pot, we could have some 'joined-upness'.” — Sir Sadiq Khan, Mayor of London
- “his criticism is a fair one” — Sir Sadiq Khan, Mayor of London
- “Polanski later told the Local Democracy Reporting Service (LDRS): “We need to be honest about the scale of the challenge London still faces from the climate crisis.” — Zack Polanski, Green Party Leader, London Assembly
- “The mayor is right to say London isn’t on course for net zero by 2030 – we should be targeting more effort at that now.” — Zack Polanski, Green Party Leader, London Assembly
- “Photograph: London Assembly “There are so many other benefits London could have from the investment we need – cheaper energy, cooler homes and better transport.” — Zack Polanski, Green Party Leader, London Assembly
Implications and Next Steps
The mayor’s demand for devolution highlights the importance of grid control for meeting urban climate goals. While the 2026-2029 integrated settlement may improve funding coordination, without statutory grid authority London’s decarbonisation pace remains constrained. Ongoing talks with central government and the planned retrofitting programme will determine whether the city can narrow the emissions gap before 2030.
