UK Sets Ambitious 2035 Emissions Target in Law: Accelerating Toward Net Zero
The UK enacts the world's most ambitious climate target, pledging over 80% emissions reduction by 2035 and advancing net zero leadership.
UK Sets World-Leading Emissions Target: A Turning Point in Climate Action
The United Kingdom has taken a historic step by enshrining an ambitious target in law to slash greenhouse gas emissions by 81% by 2035 compared to 1990 levels. This commitment puts the UK at the forefront of international climate ambition and defines the nation’s trajectory toward net zero emissions by 2050.
Why the 2035 Emissions Target Matters
- Ambition: The new goal surpasses previous major-economy commitments and sets a global benchmark for rapid decarbonization.
- Legal Clarity: Enshrined through the Climate Change Act, this target forms the UK’s sixth Carbon Budget, providing transparency and accountability for policymakers and the public.
- Inclusive Scope: For the first time, it incorporates emissions from international aviation and shipping, ensuring the full carbon footprint is addressed.
- Paris Aligned: The target represents a credible, science-based pathway to limit global warming to 1.5°C, consistent with the Paris Agreement.
Building on Past Climate Leadership
The UK’s emissions trajectory has sharpened in the past decade:
- 2015: The Paris Agreement established a framework for nations to submit Nationally Determined Contributions (NDCs) for emissions cuts.
- 2020: The UK’s 68% reduction target by 2030 was the most ambitious of any major economy and formed a key part of international climate negotiations.
- 2025: The nation submitted its updated 2035 NDC, targeting an 81% reduction, cementing its leadership and rapid acceleration.
- 2050: The legally binding goal remains to achieve net zero emissions.
Understanding the UK’s Sixth Carbon Budget (CB6)
The sixth Carbon Budget—the framework governing UK emissions between 2033 and 2037—goes further by including sectors and categories previously omitted:
- Greenhouse Gases: Covers all major GHGs—CO2, methane, nitrous oxide, and F-gases.
- Sectors: Encompasses energy, transport, buildings, land use, agriculture, international aviation, and shipping.
- Legal Enforcement: Introduced in Parliament and binding under the Climate Change Act.
The CB6 sets the UK more than three-quarters of the way toward net zero and ensures continued progress under Paris Agreement obligations.
Comparative Climate Action: How Does the UK Stand Globally?
| Country | 2030 Target (% from 1990) | 2035 Target (% from 1990) | Net Zero Year | Includes Aviation/Shipping |
|---|---|---|---|---|
| United Kingdom | 68% | 81% | 2050 | Yes |
| European Union | 55% | — | 2050 | No |
| United States | 50–52% (from 2005) | — | 2050 | No |
| China | Peaks by 2030 | — | 2060 | No |
The UK’s target remains the most ambitious among leading economies, widely credited as a “shining example of climate leadership” by international organizations.
Importance of Sector-Specific Decarbonization Goals
- Energy: A transition to renewables and advanced technologies is crucial to achieve rapid decarbonization.
- Transport: Accelerated rollout of electric vehicles and enhanced public transport infrastructure.
- Buildings: Upgrades to energy efficiency, low-carbon heating, and retrofitting will reduce residential and commercial emissions.
- Agriculture and Land Use: Supporting farmers to adopt regenerative, climate-safe practices; rewetting and restoring peatlands for carbon sequestration.
- Industry: Investment in cleaner processes and materials, including decarbonizing steel, cement, and chemicals.
Experts emphasize that achieving the 2035 target requires strong policies, regulation, and targeted investment across all sectors.
Role of Nationally Determined Contributions (NDCs)
Under the Paris Agreement, countries periodically submit updated NDCs—outlining their ambitions for emissions reductions and resilience-building. The UK’s new submission:
- Represents an economy-wide approach.
- Was submitted ahead of the 2025 deadline and COP30 summit in Brazil, signaling climate leadership.
- Complies with latest scientific advice and aligns with international obligations.
- Reflects lessons and recommendations from the COP28 Global Stocktake, which urged increased ambition globally.

Key Challenges Ahead: Turning Targets into Action
- Policy Implementation: Delivering on the legally binding target requires robust new policies, sector targets, and effective regulatory frameworks.
- Green Investment: Scaling investment in clean technologies and infrastructure—from wind farms to heat pumps—is essential for decarbonization.
- Societal Transformation: Public engagement and support for behavioral change will be needed—from transport choices to heating systems and diets.
- Job Creation: The transition offers new opportunities in green industries, but planning and support are necessary for displaced workers.
- Global Influence: The UK’s leadership can set a precedent, encouraging other G20 economies to increase their own ambition.
The Government’s Vision: Raising the Bar and Securing the Future
Prime Minister statements and government announcements have framed the new 2035 target as a watershed moment for climate ambition:
- Commitment to align domestic action with global goals, limiting temperature rise to well below 2°C and preferably 1.5°C.
- Legal certainty and international accountability—positioning the UK as a global leader in climate governance.
- Integration of new sectors and the entire carbon footprint in policy planning.

The UK has pledged to cut greenhouse gas emissions by 81% below 1990 levels by 2035.
How does this compare to previous UK targets?
The previous target was a 68% reduction by 2030. The new target represents significant acceleration and includes all greenhouse gases and additional sectors.
Will the target be legally binding?
Yes, the target is enshrined in law as part of the UK’s sixth Carbon Budget under the Climate Change Act.
What sectors does the 2035 target include?
It covers the whole economy, including energy, transport, land use, buildings, agriculture, international aviation, and shipping.
What needs to happen next?
The government must back its ambition with strong policy, funding, and a roadmap for implementation, ensuring society and industry transition rapidly and equitably toward net zero.
Conclusion: A National Commitment With Global Consequences
The United Kingdom’s decision to enshrine its 81% 2035 emissions reduction target marks a pivotal point in global climate governance and domestic transformation. With a far-reaching, law-backed commitment, the UK aims not only to end its contribution to climate change but also to inspire a global race toward net zero. The challenge now lies in implementation—translating vision into action and ensuring the economic, social, and technological transitions are bold, fair, and sustainable.
