What We Do

Verra catalyzes measurable climate action and sustainable development outcomes by driving large-scale investment to activities that reduce emissions, improve livelihoods, and protect nature.

Verra’s standards and programs:

  • Are trusted by a broad range of stakeholders, including NGOs, the private sector and governments, and are widely recognized and used in voluntary and compliance markets because they deliver credible and transparent assessments of project performance.
  • Provide innovative solutions to environmental and social problems by identifying opportunities where clear and robust measurement and reporting of on-the-ground interventions can help tackle at scale the world’s most pressing challenges.
  • Work for people and the planet by supporting projects and activities that deliver a range of benefits to communities and the environment.

The standards and programs Verra develops and manages are globally applicable and advance action across a wide range of sectors and activities. All of our programs undergo extensive stakeholder consultation and expert review, and draw from four key components: standard,  independent assessment, accounting methodologies, and registry.

How We Do It


  • Guiding principles
  • High-level requirements
  • Processes to follow

Independent Assessment

  • Accreditation of auditors
  • Training of auditors
  • Oversight

Accounting Methodologies

  • Establishing a baseline
  • Monitoring requirements
  • Enabling various interventions


  • Listing of program information
  • Avoid double counting
  • Transparency of results


Standard: Establishes the core rules and requirements that must be met for any project, program or activity to be certified under the framework. Depending on the circumstances, our standards may set out higher-level requirements or, for more complex endeavors, include more detailed rules and procedures.

Independent Assessment: Ensures that projects, programs and activities meet our standards. Where standards require independent auditing or verification, we establish processes for accrediting auditors, overseeing their work, and sanctioning them if they underperform. We provide support and oversight to established accreditation programs to ensure cost-effective and high-quality independent auditing.

Accounting Methodologies: Allow for the determination of baselines (i.e., what would have happened in the absence of the project, policy or program) and set out specific parameters for measuring, accounting, and monitoring impacts.

Registry: Displays the performance of projects, programs or activities to allow tracking of results or, in some cases, tradable units. The final programmatic component of a typical standards framework and essential to functioning certification markets, registries provide tracking services to account holders and transparent project documentation to the public.
