Protocol Supporting Documents

Document/Tool (version) Description
Eligible Biochar Feedstocks List The feedstocks listed herein are eligible for inclusion under a biochar project registering under the Reserve’s U.S. and Canada Biochar Protocol.
Eligible Biochar End Uses List The end uses listed herein are eligible for inclusion under a biochar project registering under the Reserve’s U.S. and Canada Biochar Protocol.
Mean annual soil temperature GIS layer The Reserve provides a standardized spatial layer of mean annual soil temperature to be used by project developers to determine the soil temperature of end use locations associated with the biochar from the project.
Biochar CRT Calculation Tool v1.0 (coming soon) The Reserve has developed a Biochar CRT Calculation Tool to assist with the quantification of projects using the U.S. and Canada Biochar Protocol. The equations in the tool mirror those in the protocol and perform calculations for all required and optional SSRs to conduct protocol-compliant emission reduction estimations. Use of the tool is optional.
Biochar Sample Reporting Tool v1.0 (coming soon) The Reserve provides a Biochar Sample Reporting Tool that helps project developers document how ongoing laboratory results compare to the running averages from prior results and determine if new Initial Parameter Sampling must be performed.
Approved Laboratory Analytical Standards Accepted laboratory analysis methodologies that can be used by projects currently includes:

  1. IBI Standardized Product Definition and Product Testing Guidelines for Biochar that Is Used in Soil
  2. World Biochar Certificate – Guidelines for a Sustainable Production of Biochar
