Reaching Zero: how legal services can accelerate the transition




Let’s Talk Voluntary Carbon Markets


Slide 1

The LSA Carbon Calculator is a free to use online platform that members can use to measure all your emissions – across scopes 1 2 and 3. Compliant with SECR and SBTi this online tool has been designed especially for law firms. Use it as many times as you want for as many locations as you want.

Slide 1

Simply collect your emissions data for energy, water, waste, travel, procurement and scope 3 supply chain – and the tool does the rest. Using the latest DEFRA emissions factors the Carbon Calculator gives you an accurate picture of your annual CO2e emissions.

Slide 1

Set targets for reduction. Your carbon footprint is the starting point to set targets for emissions reduction. You don’t have to be an SBTi firm to be on a net zero journey – set a target to reduce year on year and start your journey today.

LSA members leading the way in the transition to Net Zero

"Transparent target setting helps us integrate sustainability so that it becomes part of our everyday culture and how we do business. This approach benefits clients too. It means our lawyers increasingly look at the world through a sustainability lens making them more effective at advising clients on their own transition journeys and able to spot opportunities for collaboration."

Jeff Twentyman, Partner and Head of Sustainability at Slaughter and May
