A group of 138 legal sector organisations including top City firms will publish a report on their climate change performance in a live webcast next week.

The Legal Sector Alliance (LSA) report will show the extent to which members of the group have complied with the six key climate change principles set out by the alliance.

It will reveal whether firms have succeeded in measuring and reducing their carbon footprint, and making themselves accountable by publishing the figures. It will also assess how many of the member firms are advising clients of their obligations in relation to climate change, and engaging in the public debate on the issue.

A spokeswoman for the Law Society, which is a founding member of the group, said the report was a ‘significant sustainability milestone for the legal sector’.

Executive LSA members include national firms Addleshaw Goddard; Eversheds and DLA Piper; Newcastle firm Dickinson Dees and City firms Allen & Overy; Freshfields Bruckhaus Deringer; Herbert Smith; Linklaters; Slaughter and May and Taylor Wessing.The report will be broadcast over the internet on Wednesday.
