The climate emergency has never felt more pressing nor more urgent. Since 2007 the LSA has been providing support and advice to law firms across the UK helping them to manage and reduce their carbon emissions to become more sustainable.


Relaunched in 2020, the LSA is here to help members make the transition to Net Zero.

About us

The LSA is open to all law firms, schools of law and in house counsel. It is a collaborative network in which members share best practice and work together to ensure law firms play a full part in tackling the climate crisis.

Members can access a range of tools, resources, advice and exclusive benefits to help them on their sustainability journey.

Become a member

Whether it is changing your own practices, advising your clients or supporting your staff, it is vital that the legal sector as a whole reduces its impact on the planet. 

Whether you are just starting to measure your carbon footprint or are already well on your way to setting a Net Zero target, the LSA is here to help you.
