GHG Inventory

Greenhouse Gas Inventory support

Project description

Local governments across the U.S. are setting ambitious targets to reduce GHG emissions towards achieving the goals of the Paris Agreement. Developing a baseline of community and municipal emissions is a first step to set and achieve these mitigation targets. An inventory allows local governments to identify the sector-specific activities best positioned to contribute to community-wide GHG reductions. In spite of the importance of an inventory, local governments often lack the technical know-how and resources to conduct this analysis. Local governments with available resources often hire consulting firms to conduct inventories. Others have full-time staff assigned to this task. Unfortunately, this is a very small sub-set of the 39,000 local governments in the United States. Both the well-resourced and under-resourced local governments turn to ICLEI for GHG inventory support.

Measured, quantitative outcomes / project impact

In 2010, ICLEI USA created the protocols by which U.S. local governments account for emissions at both the community and municipal scale and in 2013, developed ClearPath, an emissions inventory and management software application, which is the manifestation of these protocols. In combination, these activities have reduced the financial and administrative burden to measure and manage GHG emissions. 900 U.S. local governments have established ClearPath accounts. ICLEI USA technical advisors support users who developed 336 community inventories and 196 municipal inventories in 2019. Occasionally, local governments outsource the inventory development to ICLEI USA. In 2019, ICLEI USA developed inventories for: Manhattan Beach, San Jose and Carson California; Boulder, Lakewood and Northglenn Colorado; Boca Raton, Oakland Park, and Pinecrest Florida; Beacon, New York; Beaverton Oregon; Denton and Plano Texas; and King County, Washington.
