GHG Strategies

How are GHG reductions calculated?


Greenhouse Gas (GHG) emission reductions are calculated based on the California Air Resources Board (ARB) Quantification Methodology.

Applicants will calculate estimated reductions using the AHSC Benefits Calculator Tool and AHSC Quantification Methodology. These resources can be found on the CCI Quantification Benefits, and Reporting Materials webpage.

Top GHG Reduction Strategies

In order*:

1.  Housing

  • Increase the total number of units in a project
  • Increase the dwelling units per acre (over the program requirements)
  • Include mixed use development

2.  Parking

  • Reduce below standard Institute of Transportation Engineers parking rates
  • Unbundle housing and parking costs

3.  New Transit Service

  • Include a vehicle purchase to capture GHG reduction

4.  Active Transportation Infrastructure

  • Add new bike lanes
  • Add new pedestrian paths
  • Include a bike share station

 5.  Transit Subsidies

  • Provide deeper subsidies to increase GHG reduction

6.  Other Sustainable Transportation Infrastructure

  • Include traffic calming measures such as: curb extensions, marked crosswalks, on-street parking, etc.

*Specific GHG reductions depend on your project location and the extent of investment in the above strategies.
