81% Reduction in GHG Emissions by 2035 (UK NDC)

Commitment: Reduce UK greenhouse gas emissions by at least 81% compared to 1990 levels by 2035. This is the UK’s Nationally Determined Contribution (NDC) submitted to the United Nations Framework Convention on Climate Change (UNFCCC) under the Paris Agreement.

Owner: DESNZ / HMT (cross-government)

Target date: 2035

Legal/international basis: UNFCCC Paris Agreement; submitted as UK NDC.

Metric: UK total GHG emissions (territorial basis) as % reduction vs. 1990 baseline.

Status: active

Context

The 81% NDC was submitted in 2025 and is broadly aligned with the Climate Change Committee’s recommended 6th Carbon Budget pathway. It is more ambitious than the previous UK NDC (68% by 2030 submitted in 2020).

The 2035 NDC functions as the key international accountability milestone between the 95% clean electricity target (2030) and net zero (2050).

The 81% economy-wide target by 2035 requires significant progress in decarbonising:

  • Transport: Accelerating EV transition; public transport investment
  • Buildings: Heat pump deployment; building fabric insulation
  • Industry: CCUS deployment; green hydrogen in heavy industry
  • Agriculture: Methane and nitrous oxide reduction (contested — no agriculture-specific statutory target)
  • Land use: Woodland and peatland restoration contributing negative emissions

Key tension

The CCC has assessed that current policies are not on track to meet the 6th Carbon Budget (which the 81% NDC is aligned with). This creates a gap between international commitment and domestic delivery trajectory.
