• Green building ordinance
• Food waste collection
facilities improvements, bike share
• LED streetlighting project
• PTDM, bike and pedestrian
• MFIP includes EE and RE
• Poor data sources and poor documentation of methods
• Addressed municipal & community emission reductions
• Rough estimate of 1990, 1998 GHG emission
• Many actions completed, or are ongoing
• Discovered we couldn't measure progress very well
• More robust inventories became a priority
Climate Action Planning
• 2002 Climate Action Plan
Vehicle model & year (est. MPG) x annual VMT = estimated gasoline use
Calculating Emissions 101
Formula:
Activity Data (units) x Emission Factor (MT CO, e / unit) = Emissions (MT CO, e)
gasoline use (N/A) x emissions per gallon gasoline (EPA) = (MT CO,e)
Examples:
kWhs used in buildings (Eversource) x emissions per kWh (ISO NE Grid) = (MT CO, e)
