The Climate Trust requests project developers use the following conversion metrics for 2005 RFP offset project calculations. Please note that volume of carbon offsets must be converted to metric tons of carbon dioxide on project applications. If an alternative factor is used, clearly state the source.

Other Resources

Electricity: The Climate Trust has created an Electricity Sector Baselines Resources page for data on the quantification of projects that displace grid electricity.
Forest Sequestration: The Climate Trust does not have standard quantification metrics for forestry-based projects. Carbon sequestration levels vary according to site location, tree species, and project activity. The Trust encourages project developers to make use of the best available data.
Industrial Processes and Other Carbon Factors:
- The IPCC's Emission Factor Database is a great resource for industrial carbon factors, as well as most other sectors.
- The GHG Protocol has a variety of spreadsheets/tools and guidance to assist in the quantification of GHG emissions from a variety of sectors.
