UK commits to 81% emissions cut by 2035

The Rt Hon David Lammy, UK Deputy Prime Minister, announced the UK’s Nationally Determined Contribution to cut greenhouse gas emissions by at least 81% by 2035 versus 1990 levels.

• Main announcement: The UK’s NDC commits to an at least 81% reduction in greenhouse gas emissions by 2035 (baseline 1990); the pledge is economy-wide, covering every single sector, and is stated to be aligned with keeping global warming to 1.5°C. This NDC was first announced by the Prime Minister at COP29.
• Background and implementation details: The speech cites the UK as the first major economy to halve its emissions while growing its economy by over 80%, and notes the UK green economy grew three times faster than the wider economy last year. The UK pledges continued support for developing countries via the NDC Partnership and calls for COP30 in Belém, Brazil to be a turning point that delivers credible pathways to accelerate action; the speech references global pathway estimates (2030 NDCs → 2.6°C; fulfilling Net Zero commitments → 1.9°C).
