Methodologies for quantifying project benefits are a key component of all Verra standard programs. All methodologies undergo a rigorous review and transparent stakeholder consultation process to ensure they meet the rules and requirements of each program.

VCS Program Methodologies

Methodologies are essential to quantifying real and accurate greenhouse gas (GHG) benefits of a project and to generate Verified Carbon Units (VCUs). Methodologies provide requirements and procedures to determine project boundaries, identify the baseline, assess additionality, monitor the relevant parameters, and ultimately quantify the GHG emission reductions or removals.

Methodologies often refer to modules or tools, which include specific methodological tasks and analyses (e.g., additionality) that are used in conjunction with the methodology.

The VCS Program has its own methodologies that have been approved for use.

In addition, projects seeking registration in the VCS Program that comply with all VCS Program rules may use selected methodologies from other approved GHG programs, including Clean Development Mechanism (CDM) methodologies and Climate Action Reserve (CAR) protocols.

The following CDM and CAR methodologies are active in the VCS Program and may be used, if projects comply with all VCS Program rules and requirements. Projects can only be listed on the VCS registry if they are not excluded from the VCS Program in accordance with Table 1 of the latest version of the VCS Standard.

VCS Program – Inactive Methodologies

Verra periodically reviews VCS methodologies to ensure they continue to reflect best practices, scientific consensus, and evolving market conditions and technical developments in a sector. Verra will conduct these reviews at least once every five years or when otherwise needed.

As a result of a review, Verra may revise the methodology. Verra may also set methodology versions previously approved under the VCS Program as inactive until a new revised version is issued.

Inactive CDM Methodologies

Verra has inactivated CDM and CAR methodologies from the VCS Program that have had limited or no use. These are considered inactive under the VCS Program. Project proponents who are interested in using one of these methodologies may send a request to methodologies@verra.org. The request should include:

  • A list of projects (you may consider including similar ongoing projects from other developers)
  • Estimated amount of annual emission reductions
  • A justification that there is no eligible methodology that could be used for your project(s)
  • Status of the implementation of the activity

Per the VCS Standard, v4.7 (PDF), Section 3.22.3(4), Verra has set the grace period for inactivated CDM methodologies to twelve months after the date they were inactivated. Project proponents that have already requested listing on the Verra Registry before the inactivation date may complete validation within twelve months after the inactivation date.

Projects may not use methodologies from other approved GHG programs that overlap with VCS methodologies. The following methodologies are permanently excluded from the VCS Program (see Sections 5.3.6 of VCS Methodology Development and Review Process, v4.4 (PDF):

A number of VCS methodologies are currently under development.

Propose a new or revised VCS methodology, tool or module

Stakeholders can submit a methodology idea note to propose a new or revised VCS methodology, tool or module (refer to the Methodology Development and Review Process).

Preference and priority to proceed with the development process of such ideas are given to ideas that are broadly applicable, have high climate change mitigation potential, support sustainable development, and are not associated with unmitigable social, environmental, legal, or regulatory risks.

Depending on available funding, experience and overlapping ideas, either a third-party or group of third-parties leads the development of the proposed new or revised methodology, tool or module. Verra may also fund the development and hire a consultant to prepare the methodology documentation and manage the assessment process.


SD VISta Program Methodologies

Projects have the option to generate SD VISta assets that represent specific sustainable development benefits. Projects that generate SD VISta assets must use an approved SD VISta asset methodology to quantify the specific social or environmental benefits that will be issued as assets.

SD VISta asset methodologies set out the assumptions, parameters, and procedures for measuring, monitoring, and reporting the specific sustainable development benefits. They also provide detailed procedures for quantifying the real environmental and/or social benefits of the project and provide guidance to help project developers determine project boundaries, set baseline scenarios, monitor the benefits, and ultimately quantify and issue the sustainable development benefits as SD VISta assets.

Project developers can choose to develop their own SD VISta asset methodology through the SD VISta methodology approval process.

The SD VISta Program has methodologies approved for use.

*no current modules exist for SD VISta methodologies

*no current tools exist for SD VISta methodologies

A number of SD VISta methodologies are currently under development.


Plastic Program Methodologies

Methodologies set out detailed procedures for quantifying the plastic waste collected and/or recycled as the result of a project activity and provide guidance to help project developers determine project boundaries, set baselines and assess additionality.

Project proponents must always use the current and valid version of a methodology. Select from the methodologies below based on the nature of your project activity.

To ensure that the Plastic Program remains robust and credible, the Plastic Program periodically reviews approved methodologies to ensure that they conform to current requirements, international best practices, and scientific consensus. Therefore, from time to time, a methodology may be revised, withdrawn or put on hold. In such cases, A grace period will apply for projects currently using the methodology. The status of each methodology is always displayed on the Verra website.
