UK emissions reductions 2026: what the latest figures actually show

The latest provisional government figures put UK net territorial greenhouse gas emissions at 367 million tonnes of carbon dioxide equivalent in 2025, down 2% from 2024 and 54% from 1990. Most of the long-term fall came from electricity, leaving transport, buildings and industry to carry more of the next reduction.

Department for Energy Security and Net Zero (DESNZ) data records a substantial fall over three decades. Coal has left the power system, renewable electricity has grown, industrial output and fuel use have changed, and energy demand is lower than it was in 1990.

The national total also hides sharp differences between sectors. Domestic transport, now the largest source of UK territorial emissions, rose in 2025. Buildings remain heavily affected by weather and gas heating, while agriculture, land use and aviation are harder to move quickly.

UK emissions fell another 2% in 2025

The long-term fall dwarfs the latest annual drop

The UK has cut more than half of its territorial emissions since 1990, but the latest annual fall was modest. Remaining emissions are concentrated in sectors where reductions are less straightforward than closing coal plants.

Transport rose in 2025 while industry and fuel supply fell

Further reductions now have to come from several sectors at once. The power system must preserve its gains while petrol and diesel use, building heat, industrial production, agriculture and land use all move in the same direction.

Most of the long-term fall came from electricity

A 54% reduction from 1990 is not a marginal accounting change. It reflects major changes in the electricity system, energy demand, industrial structure and fuel use.

The UK low-carbon economy figures show rising turnover in low-carbon and renewable energy activity. The emissions series shows whether that activity is accompanied by lower territorial emissions.

DESNZ says the long-term fall since 1990 was driven heavily by electricity generation moving away from coal, first toward gas and later toward renewables, alongside lower electricity demand and changes in energy-intensive industry.

The UK electricity generation mix in 2026 puts that change in context: renewables supplied more than half of generation in the first quarter and coal was absent, while other sectors remained dependent on fossil fuels.

Territorial emissions leave part of the UK footprint outside the count

A falling territorial total does not mean the UK is comfortably on track for net zero.

The figures count emissions produced within UK borders. They exclude emissions embedded in imported goods and services, and they do not treat international aviation and shipping in the same way as domestic sectors. Carbon budgets use this territorial boundary, but it is not the same as the UK's full consumption footprint.

Second, some of the latest reductions may not be easily repeatable. A fall caused by lower blast furnace use is different from a fall caused by durable low-carbon industrial production. Lower heating demand in a warmer period is different from millions of homes becoming easier to heat cleanly.

Third, the largest sector, domestic transport, increased in 2025. The Climate Change Committee keeps pointing to electric vehicle (EV) uptake, charging, buildings and wider electrification as central delivery tests. For the infrastructure side, read the Progress check on UK public EV charging in 2026. For the buildings side, use the Progress checks on UK heat pump rollout in 2026 and school and NHS solar installations.

Current policy still falls short of the 2030 target

The Climate Change Committee (CCC) reaches beyond the latest annual total in its 2026 progress report. It says the pace of UK emissions reduction needs to almost double to keep the 2030 target within reach.

The key gap is the UK's 2030 Nationally Determined Contribution (NDC), its international target under the Paris Agreement. The CCC says the government's current pathway falls short of that target, even though it may be more credible against some earlier carbon budgets that were set before the UK adopted net zero.

A country can be ahead of an older budget and still fall behind a stronger net-zero-aligned milestone. The Climate Change Committee's assessment is therefore more demanding than a comparison with 1990 alone.

For the legal pathway behind the target, read the Seventh Carbon Budget guide. For the broader definition, read what net zero means.

Further cuts now depend on transport, buildings and industry

Transport needs petrol and diesel demand to fall in absolute terms. Buildings need heat-pump deployment, insulation, electricity pricing and public-sector retrofit, including public-building solar, to move fast enough to show up in emissions data. The Carbon Budget and Growth Delivery Plan heat and buildings factsheet shows where government wants private capital to look, but the emissions data still decides whether that market story becomes delivery. Industry needs lower-carbon production rather than only lower production. Agriculture and land use need evidence that emissions and removals are changing in ways that can be measured credibly.

The 2025 estimate continues the decline, but future reductions will have to arrive after many of the largest power-sector gains have already been secured.

The next reductions need to appear beyond the power sector

• Whether final 2025 emissions, due in 2027, confirm the provisional 367 million tonne estimate.
• Whether domestic transport emissions start falling again in absolute terms.
• Whether buildings emissions fall in a way that cannot be explained mainly by warmer weather, including whether heat-pump redemptions and retrofit activity keep rising.
• Whether industry emissions fall through cleaner production rather than reduced output alone.
• Whether agriculture, land use and waste data become clearer in final emissions statistics.
• Whether government delivery plans close the gap to the UK's 2030 international target.
