ICLEI is the lead author, supported by groups of city and carbon accounting experts from various fields, in the development of industry standards for local government GHG emissions accounting in the US. The development of the U.S. Community Protocol, the Local Government Operations Protocol, and the Recycling and Composting Protocol positioned ICLEI as exclusive experts in local government carbon accounting. Recognizing this expertise, ICLEI was asked to contribute to the development of the Global Protocol for Community Scale GHG emissions (GPC) and is currently working on an update to the U.S. Community Protocol to better account for forestry and land use changes. ICLEI continues to provide technical guidance for the application of the protocols to cities and practitioners around the world.
