Cornerstone Climate

Wind turbines

Cornerstone Climate is a cross-disciplinary practice group for environment law, climate change litigation and advice drawing on our award-winning planning, environment, property, commercial, regulatory and public law teams. Our barristers are frequently involved in major climate cases, both in court and at public inquiry.

Cornerstone Barristers has a strong track record of involvement in climate cases and of giving strategic, carbon-literate advice, including to all levels of government. The climate and biodiversity crises have triggered legislative, regulatory and market responses that affect clients across planning, environment, property, commercial and public law. Awareness of, and potentially imaginative solutions to, climate and biodiversity risks are required.

Our aim is to fortify and expand the services we provide clients on climate and biodiversity matters, as well as to act as a hub bringing professionals together from across the construction, development, public policy and commercial worlds to share best practice and insight, hosting regular in person and online events.

In our hub below you’ll be able to learn about our expertise, access useful climate resources and sign up for future Cornerstone Climate events.

  • Legal challenges

    Cornerstone Barristers has some of the most highly regarded barristers involved in environmental legal challenges, frequently instructed in high profile cases at the Supreme Court, High Court and Court of Appeal.

    Recent highlights of our work include:

    • Finch v Surrey County Council (Supreme Court case). A hugely significant case for environmental law and climate change concerning the question of whether, when considering an application for the commercial extraction of oil, Surrey County Council should have required an assessment of the emissions likely to be caused by the use of products manufactured from the extracted crude, and their impact on the climate.
    • The government’s Net Zero Strategy. In this legal challenge, the High Court held that the UK Government did not comply with requirements under the Climate Change Act 2008 to produce policies and proposals that will enable net zero to be met by 2050, and to report on those policies in a transparent way to Parliament when it produced its flagship Net Zero Strategy in advance of COP26.
    • Balcombe hydrocarbon exploration. Tom Cosgrove KC and Ben Du Feu acted for the Secretary of State in dismissing a statutory challenge to the grant of planning permission for exploration and appraisal works with an extended well test for hydrocarbons at an existing well site at Lower Stumble, Balcombe.
    • Challenge to UK government’s oil and gas expansion plans. This challenge by a leading UK climate change non-governmental organisation, Uplift, to the government’s UK Offshore Energy Strategic Environmental Assessment, which concluded that a policy allowing new seaward oil and gas licensing would not have significant environmental impacts.
    • Whitehaven coal mine. The statutory review of the controversial decision by the Secretary of State for Levelling Up, Housing and Communities to approve the first new coal mine in the UK for over 30 years, purportedly the world’s first ‘Net Zero’ coal mine.
    • Solar farm appeals belatedly contended as Nationally Significant Infrastructure Projects (NSIP). A significant challenge brought by two planning authorities against the Planning Inspector’s decision that it had jurisdiction to determine appeals in respect of solar farms under the Town and Country Planning Act 1990. The authorities unsuccessfully contended that the solar farm development was NSIP, which needed to be determined under the Planning Act 2008.
    • HS2 tunnelling in the Chilterns. A judicial review claim brought by local residents in the Chilterns challenging the Environment Agency’s decision to grant consent for a twin tunnel for the purposes of the HS2 project. Planning permission was refused in November 2021.
    • Southampton Airport expansion. A judicial review challenge to a decision made by Eastleigh Borough Council to approve a runway extension at Southampton Airport.
