Scope 3 Emissions Workshop


Tuesday, 29 November 2022, 12:00 – 13:00 GMT

The indirect greenhouse gas (GHG) emissions associated with a typical law firm’s value chain (i.e. its Scope 3 carbon emissions) can often make up 80-95% of the firm’s total carbon footprint, yet Scope 3 is often one of the most difficult areas to get a handle on.

This practical workshop will help you to understand:

  • what activities typically result in Scope 3 GHG emissions for a law firm
  • how to go about getting hold of the information needed to calculate the associated carbon footprint
  • what steps can be taken to reduce this important part of the firm’s total carbon footprint

Limited to 15 places to ensure maximum participation.

Please note that this event is for current 2022 LSA Members only.


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.
