Inspiring ambitious transformative action to combat the climate crisis
Our Purpose
Guided by alignment with a 1.5-degree world, Legal Charter 1.5 facilitates the collaboration necessary to enable law firms to tackle complex challenges, to deepen and accelerate their responses to climate change and help them to effectively inform, advise and assist clients.
Our Principles
We have refined our principles and approach to better reflect the complexities and challenges facing the legal sector:
LEADERSHIP
Demonstrating climate leadership internally, with clients, and across the sector
INNOVATION
Commitment to tackling core climate questions for law firms
COLLABORATION
Genuine commitment to work together to deliver systems change across the sector
CLIENT ENGAGEMENT
Working with and supporting clients to respond to climate change
Our Work
Legal Charter 1.5 firms commit to showing leadership and supporting the overall purpose and direction of the Charter, and are encouraged to join at least one workstream, each of which is chaired by a member firm and supported by the secretariat. Not all firms will participate in all workstreams.
Workstreams include: Leadership, Matters and Mandates, Meaningful Offsetting, Education and Upskilling, Governance, Pro Bono and the GC Forum.
