Climate change and air pollution

Start a climate change claim and help us fight air pollution in the UK today

We are at the forefront of the fight against climate change in the courts, pushing the Government to take into account the more ambitious CO2 reduction targets under the Paris Agreement and as advised by the IPCC, as well as applying pressure on local authorities to have regard to the climate change impact of the decisions they make about everyday services.

In doing so, we tailor our litigation approach to the wider campaigning priorities of our clients to use litigation as a stimulus for faster adaptation to, and mitigation of, climate change. For example, we are involved in legal challenges opposing the Heathrow airport expansion and the Government’s national planning policy framework in respect of the carbon impact of fracking.

As the scale of the public health danger presented by air pollution continues to grow, we are seeking to persuade the Courts that the Government can go further in using its powers to properly tackle air pollution, both at a local and national level. This has involved detailed knowledge of the EU’s Air Quality Directive and UK environmental protection laws.

What is climate change law?

Climate change law consists of policies and legislation that are designed to reduce greenhouse gas emission levels. A reduction in these figures can fight climate change and reduce our negative impact on the environment.

Businesses, government projects and local operations must therefore comply with climate change law. In instances where it is not followed, individuals and NGOs can use it to bring legal challenges.

The Climate Change Act was introduced in the UK in 2008, implementing legally binding carbon emissions targets. Crucially, it introduces a legal binding target on the Government to achieve Net Zero by 2050. As part of that, there is a duty to set interim carbon budgets every 5 years and prepare policies on a continuing basis to enable those budgets to be met. It also sets a framework for climate change action across the country, including a carbon emissions trading scheme.

How Leigh Day can support using climate change law

Our team has built up a wealth of knowledge surrounding climate change policies and the Government’s framework, through advice given by the Climate Change Committee and research undertaken by the Intergovernmental Panel on Climate Change. We utilise this knowledge to tailor our litigation approach to the wider campaigning priorities of our clients, and to use climate change law to help tackle the urgent climate crisis facing the planet.

Most notably, we have led legal challenges opposing the Heathrow airport expansion, the Government’s Net Zero Strategy and HS2, placing us as leaders in major infrastructure projects litigation. We are teaming up with environmental campaigners to oppose greater fossil fuel extraction (both onshore and offshore) and to dissuade public bodies from funding such projects.

We also act for campaigners challenging the UK’s emissions trading scheme for excluding municipal waste incineration. Additionally, we have responded to Government policies that restrict renewable energy and promote shale gas as a positive contribution to a low-carbon economy.

Air pollution law

Air pollution in the UK is costing the economy over £20 billion a year by causing poor health and early deaths. Existing air pollution law is in place to reduce this negative impact, including: the 2021 Environment Act, which sets targets for air quality; the 2010 Air Quality Standard Regulations, which imposes a duty to ensure the levels of toxic pollutants do not exceed limit values and, where they do, to bring those levels into compliance within the shortest possible time; and the 1995 Environment Act, which requires local authorities to review air quality in their area and prepare plans to reduce pollution where improvements are necessary.

As air pollution continues to pose an increased danger to public health, we aim to persuade the Courts that the Government can go further in tackling air pollution at both a local and national level. Leigh Day has been, and is currently, instructed on several challenges to planning developments and policy on air quality grounds.
