LSA Spotlight

 What has got us talking this week: 



Climate Impact Partners have developed a series of briefings for COP.  “What Carbon Project Developers Need to Know Ahead of This Year’s Global Stocktake” is 51 minutes long and designed to keep you up with the latest guidance and initiatives.

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.
