City and County of Honolulu
Greenhouse Gas Emissions Inventory

As part of the City’s commitment to the Paris Climate Agreement, the City completed its first GHG inventory for calendar years 2005, 2015, and 2016 in the fall of 2018. The GHG inventory accounts the annual total amount of carbon pollution emissions by sector and source in our island economy, and serves as a benchmark to reduce our emissions each year moving forward.
