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 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.
Randomized Date List for Retention Sampling At the end of each month, the Reserve will post a list of randomized dates for the previous two-month period. Project Developers must retrieve the list for any two-month period during which biochar was produced under the project.

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 include those specified by:

  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

In addition to the methodologies included in the standards listed above, the following methodologies are approved for use by projects for individual analytical targets:

Analytical Target Methodology
Total H, total C, Corg content and H:Corg ISO 16948 CHN,
ISO 18122 Ash generation (to isolate inorganic C),
ISO 18134-1 Moisture content (optional, if subtracting out H from water in the biochar)
Dry Combust-ASTM D 4373
Polycyclic Aromatic Hydrocarbons, total (8 EFSA PAH) US EPA 8270 (2007) using Soxhlet extraction (US EPA 3540) (toluene extraction not required)
Mercury ISO 16968

Cadmium
Chromium
Cobalt
Copper
Lead
Molybdenum
Nickel
Selenium
Zinc
ISO 16968
EPA 3050B/EPA 6020
