The London Group on Environmental Accounting is a city group created in 1993 to allow practitioners to share their experience of developing and implementing environmental accounts linked to the System of National Accounts. It convened its first meeting in March 1994 in London, England. The name derives from the city of its first meeting.

The London Group is an informal group of experts primarily from national statistical agencies but also international organizations. Participation by representatives is voluntary. The annual meetings provide a forum for review, comparison and discussion of work underway by participants towards development of environmental accounts.
