Scope 3 Community of Practice

Find resources and notes from the CoP, and details on how to join


Many organisations have developed methods to measure their Scope 1 and 2 emissions, but Scope 3 (emissions from things we do not own, or those in our value chain) is much harder. This Community of Practice is for organisations across the South West of the UK, as we work to find opportunities for consistency in how we understand and measure our Scope 3 carbon emissions.



The CoP is both a learning network and an action network. As a learning network, it provides a space for peer-support, the exchange of information, and increased co-ordination around a consistent approach to understanding, communicating and measuring Scope 3 emissions. As an action network, it identifies key actions to take and creates processes for these to be undertaken collaboratively.



The CoP is open to all, but is of most relevance to organisations based in or near the South West of the UK, particularly large academic and public sector institutions. This is due to the potential overlap in carbon accounting methods and supply chains, but organisations from other areas who are keen to join are welcome to get in touch. To request to join, please use the button below, and upcoming meetings can be found on our events calendar.
