The UK Climate Change Committee’s 2026 Progress in Reducing Emissions report to Parliament, published on 24 June 2026, concludes that the UK has made substantial long-term progress in reducing greenhouse gas emissions but is not acting quickly enough to meet its future climate targets. UK emissions fell by 1.8% in 2025 to 407 million tonnes of CO₂ equivalent, around 50% below 1990 levels, and the country is on track to meet its fourth carbon budget (2023–2027). However, the Government’s current policies leave a significant gap in meeting its 2030 Nationally Determined Contribution (NDC) under the Paris Agreement, which commits the UK to reducing emissions by at least 68% below 1990 levels. The Committee identifies the slow pace of electrification as a central concern, particularly in transport, buildings and industry, alongside insufficient progress in agriculture, land use and aviation. It calls for a more ambitious strategy to accelerate electric vehicle uptake, heat pump installation, industrial electrification and renewable electricity deployment, supported by lower electricity costs, improved charging infrastructure, stronger incentives and targeted support for lower-income households.
The report also highlights the implications for household finances and national energy security. The Committee argues that reducing reliance on imported oil and gas would help protect households and businesses from international price shocks, while potentially lowering energy and transport costs. Its analysis suggests that a typical household with a petrol car and gas boiler could save around £1,210 annually by switching to an electric vehicle, heat pump, solar panels and a time-of-use electricity tariff, although savings depend on the home and access to affordable charging. Overall, the Committee stresses that the UK must nearly double the pace of emissions reductions to keep its 2030 target within reach. It warns that relying on future engineered carbon removals without a credible delivery strategy creates additional risks for longer-term carbon budgets. The report calls for stronger, more consistent policies across all sectors, alongside investment in infrastructure and support for households and businesses, arguing that meeting climate targets would also strengthen energy security, improve air quality and reduce exposure to volatile fossil fuel prices.
