Carbon Calculator


The LSA has been leading the way in sustainability for UK based law firms since its inception in 2007. During that time firms have moved from measuring and managing their carbon emissions to committing to Net Zero by putting sustainability at the heart of their businesses. It is now a strategic imperative for all law firms to be working on their transition to a low carbon business model and the LSA is here to help. We aim to inform, equip and empower lawyers to take effective action on the climate and nature crises at home, at work and through their practice.

Our executive board is chaired by Caroline May and Matt Sparkes and includes representatives from 15 leading law firms and The Law Society. If you would like to become a member of the Executive Board please do contact Camilla Haycock on [email protected]
