A greenhouse gas (GHG) inventory is the standard approach to measuring community-wide GHG emissions. Concord's most recent GHG Inventory is for the year 2019. This inventory was completed in March 2021. Two previous GHG inventories were conducted for years 2008 and 2016 using the Global Protocol for Cities.
Concord also completed a wedge analysis in Jan. 2019 to analyze the emissions reduction potential of 5 actions - changes to vehicles standards, electric vehicle incentives, air-source heat pump incentives, energy efficient buildings, and zero carbon electricity.
