Protocol Development

The following timeline will be updated, if needed, as the process moves forward.

Workgroup formation June 2014
Protocol drafting June 2014 – February 2015
In-person workgroup meeting October 2014
Public comment period March – April 2015
Protocol adoption July 2015

On May 2, 2014, the Reserve issued a Request for Proposals for a technical contractor to assist with protocol development as well as a call for stakeholder interest in participation in an expert working group. Those documents can be found below (the deadline has passed and submissions are closed).

Technical Contractor

The Reserve selected WSP and Colorado State University as the team to carry out the technical contract work for the Grassland protocol. Staff worked closely with the contractors during 2014 to complete their work, which is the foundation of the quantification methodology within the protocol.


The Reserve is working closely with a multi-stakeholder workgroup to develop the Grassland Project Protocol. The workgroup includes industry representatives, federal agency personnel, environmental organizations, verifiers, and expert consultants. The workgroup includes representatives from:

Colorado State University SES, Inc.
Ducks Unlimited, Inc. The Climate Trust
Environmental Defense Fund The Nature Conservancy
Environmental Services, Inc. USDA – Natural Resources Conservation Service

Workgroup Meetings

Workgroup meetings are open to the public. Interested stakeholders can join the workgroup calls as an “observer” and listen to the workgroup discuss important issues for protocol development. Observers will not have the ability to participate in calls but will be able to stay informed by listening to the conversations as they unfold. If you are planning to participate as an observer and would like to receive workgroup meeting notices, send a message to Workgroup meeting dates will also be posted below, as soon as they are scheduled.

Over the past several years, the Reserve has been evaluating opportunities to develop carbon offset protocols for activities that increase or avoid the loss of organic carbon stored in soils:

  • In 2010, the Reserve commissioned an issue paper evaluating a possible protocol for crediting soil carbon sequestration associated with the application of biochar. Based on the findings of the issue paper, however, we elected not to pursue protocol development.
  • In early 2011, the Reserve convened a workgroup to explore development of a Cropland Management Project Protocol for quantifying soil carbon enhancements due to changes in tillage practices. This effort was suspended after further analysis and consultation with stakeholders.
  • In November 2012, the Reserve adopted the Forest Project Protocol Version 3.3, which includes a methodology to account for net soil carbon emissions and sequestration in forests. This work may help to inform future development of soil carbon protocols for non-forest projects.

Continuing with these investigations, in early 2012 the Reserve commissioned an issue paper related to two types of land-use change activities: avoided conversion of grasslands and conversion of croplands to grasslands.

The background research paper for soil carbon storage in grassland is available below.

Based on the completed issue paper and internal scoping and research activities, the Reserve has decided to move forward with the development of a protocol to address grassland projects in the United States.

Soil Carbon Scoping Meetings
