Arlington VA, October 2, 2020 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, announces an open public comment period for updates to the ACR Standard v7.0, which details ACR’s requirements and specifications for the quantification, monitoring, reporting, verification, registration and issuance of project-based GHG emissions reductions and removals as carbon credits.

Key updates include the use of 100-year Global Warming Potentials (GWPs) from the IPCC 5th Assessment Report (AR5) to calculate emission reductions, requirements to avoiding double claiming between achievement of NDCs targets and voluntary offsetting, and addition of detailed procedures to avoid double counting in the CORSIA.

Please submit written comments via ACR@winrock.org by December 1, 2020.

ACR Standard v7.0 will go into effect January 1, 2021.

JULY 8, 2020 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, is soliciting public comments on an updated Methodology for Landfill Gas Destruction and Beneficial Use.

Under the existing published methodology, projects that reduce methane emissions as a result of specified combustion or beneficial use activities are eligible for crediting emission reductions.

Version 2.0 of the methodology adds as an eligible project activity the installation of an automated collection system that increases landfill gas collection efficiency above that obtained with standard collection methods with methane destruction, conversion, or enhancement.

Automated collection systems hold tremendous promise to increase the collection of methane from landfills through the use of automatic control and measurement devices that eliminate the need for standard manual wellfield tuning. When combined with cloud- based data collection and analysis tools, automated collection systems result in the ability to continuously optimize wellfield conditions resulting in significant increases in landfill gas collection efficiency.

Stakeholders are invited to review the methodology and submit comments to ACR@Winrock.org by August 7, 2020

APRIL 15, 2019: The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, announces an open public comment period for updates to the ACR Standard v6.0, which details ACR’s requirements and specifications for the quantification, monitoring, reporting, verification, registration and issuance of project-based GHG emissions reductions and removals as carbon offsets.

OCTOBER 17, 2018 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, is soliciting public comments on two methodologies:

• Updates to the Methodology for Avoided Conversion of Grasslands and Shrublands to Cropland Production (ACoGS). Proposed revisions to methodology v2.0 are to simplify use, better align with conservation programs, and reflect the latest trends in conversion.
• A new Methodology for Capturing and Destroying Methane from U.S. Coal and Trona Mines to quantify GHG emission reductions associated with the capture and destruction of methane that would otherwise be vented into the atmosphere as a result of mining operations at active underground and surface coal and trona mines and abandoned underground coal mines. Not only an important GHG mitigation activity, coal mine methane mitigation also contributes to mine safety initiatives and can increase the supply of a clean energy source when methane is recovered and used to produce electricity or heat.

Stakeholders are invited to review the methodologies and submit comments to ACR@Winrock.org by November 18, 2018.

MAY 25, 2018 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, announces the following:

Open public comment period for updates to the ACR Standard v5.0, which details ACR’s requirements and specifications for the quantification, monitoring, reporting, verification, registration and issuance of project-based GHG emissions reductions and removals as carbon offsets.

Publication of ACR’s Guidance for Carbon Project Development on Tribal Lands, which was developed in partnership with the Indian Lands Tenure Foundation to facilitate the validation, verification, and registration on ACR of carbon offset projects located on tribal land, including both lands held by tribal nations and those held by individuals.

FEBRUARY 1, 2018 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, is accepting stakeholder comments on the update of its Methodology for the Quantification, Monitoring, Reporting and Verification of Greenhouse Gas Emissions Reductions and Removals from Advanced Refrigeration Systems.

The Methodology, developed by Dentons US and EOS Climate in cooperation with Susan Wood Consulting and True Manufacturing, is intended to incentivize GHG emissions reductions through the deployment and use of advanced refrigeration systems in large commercial and stand-alone commercial refrigeration.

The Methodology updates including making advanced refrigeration systems a stand-alone methodology and expanding the stand-alone commercial refrigeration sector to include numerous equipment types. Additional changes have been made to clarify, revise, and add context to updates.

Please send comments to ACR@Winrock.org by March 5, 2018.

SACRAMENTO, CA, November 7, 2017 – The American Carbon Registry (ACR), a nonprofit enterprise of Winrock International, is proposing updates to the ACR Standard, which details ACR’s requirements and specifications for the quantification, monitoring, and reporting of project-based GHG emissions reductions and removals, third-party verification, project registration, and issuance of offsets.

Stakeholders are invited to review the proposed changes to the ACR Standard posted on the ACR website and submit comments to ACR@Winrock.org by December 10, 2017.
