A new national policy statement for nuclear energy generation

National policy statements (NPSs) inform decision-making for nationally significant infrastructure projects. The current NPS for nuclear power generation (EN-6) has effect for listed nuclear projects capable of being deployed by the end of 2025. Both the current and previous governments have consulted on a new NPS (EN-7) that would apply to nuclear power stations expected to be deployed after 2025. This briefing gives an overview of NPSs, the proposed new NPS for nuclear power generation and the reaction to it, as well as the current government’s policy on nuclear energy.

Methane emissions: House of Lords Environment and Climate Change Committee report

In December 2024, the House of Lords Environment and Climate Change Committee published a report examining methane emissions in the UK. While acknowledging the UK’s efforts to reduce emissions, the committee expressed concerns about the UK’s international role in addressing the issue. It made several recommendations, including calling on the government to publish a methane action plan detailing how it would meet its global commitment to reducing methane emissions.

Costs of net zero by 2050

The UK’s target of achieving net zero by 2050 was set under then prime minister Theresa May in 2019. To date, there has been political consensus on the target between Conservative and Labour governments. In March 2025, the Leader of the Conservative Party Kemi Badenoch announced that her party no longer supported the target, in part because she did not believe it was affordable. This briefing examines the costs associated with achieving net zero by 2050 and how progress to the target has been legislated for under the Climate Change Act 2008.

    Biodiversity loss and climate change: Interdependent global challenges

    Nature and climate change are considered to be inextricably linked. Climate change is one of the drivers of biodiversity loss, along with factors including unsustainable food production and the overuse of natural resources. Nature is considered a key tool in combating rising global temperatures, for example forests and peatlands can play an important role in absorbing carbon emissions. This briefing summarises biodiversity loss, nature-based solutions to climate change and UK climate and nature policy.

    Long-duration energy storage: House of Lords Committee report and plans for a new scheme

    Renewable energy generation can depend on factors like weather conditions and daylight hours. Long-duration energy storage technologies store excess power for long periods to even out the supply. In March 2024, the House of Lords Science and Technology Committee said increasing the UK’s long-duration energy storage capacity would support the UK’s net zero plans and energy security. The government has announced an investment support scheme, to launch in 2025.

    Renewable energy: Costs

    Labour has committed to decarbonising the UK’s electricity system by 2030, saying this would help the UK achieve its 2050 net zero target. This briefing discusses how much renewable energy contributes to Great Britain’s electricity currently, how much it costs to generate electricity from renewable energy sources and estimates for the total cost of transitioning to a zero-carbon power system, and issues around the need to invest in supporting infrastructure such as storage technologies and grid upgrades.

    ‘Undergrounding’ electrical transmission cables

    There are 4,500 miles of overhead electricity transmission lines in England and Wales. This contrasts with just over 900 miles of underground cables. ‘Undergrounding’, the replacement of overhead cables with underground cables, is used in limited circumstances, such as in nationally designated landscapes. There have been calls for an increase in undergrounding. However, the government has pointed to several issues, including the higher cost of underground cables.
