LEAN LAWYERS wanted to understand their carbon footprint in more depth and connect it to their broader B Corp ambitions. They faced three key questions:
How do our activities translate into carbon emissions over time?
What trends can we identify by comparing results across years?
How can we use these insights to strengthen our B Corp assessment and sustainability roadmap?
To answer these questions, Regreener guided LEAN LAWYERS through a two-year carbon footprint assessment:
Calculated the firm’s complete activity-based carbon footprint for both 2023 and 2024
Identified year-on-year differences to highlight trends and opportunities for reduction
Provided hands-on support with data collection and interpretation
Delivered insights that directly contribute to LEAN LAWYERS’ B Corp assessment and broader sustainability strategy
A transparent calculation of LEAN LAWYERS’ carbon footprint for two consecutive years (2023 and 2024)
Clear visibility on emission hotspots and changes year-on-year
Practical recommendations to reduce emissions and further integrate sustainability into daily operations
Direct contribution to LEAN LAWYERS’ B Corp assessment, strengthening their case as a purpose-driven law firm
