VCS Verified Carbon Standard

​​​​​​Validation and Verification of projects under the Verified Carbon Standard​​ programme

Under VCS, projects are issued unique carbon credits known as verified carbon units or VCU. Each VCU represents a reduction or elimination of one tonne of carbon dioxide equivalent CO2e  achieved by a project. lograda por un proyecto.

AENOR, as a validation and verification entity, evaluates projects according to the VCS Programme rules and the requirements of the applied methodology. AENOR conducts an independent assessment, which is essential to guaranteeing the integrity of the projects registered in the VCS Programme. All VCS projects complete a rigorous development and assessment process before registering in the VCS Programme.


VCS validation or verification can be integrated with CCBS validation or verification (Climate, Community & Biodiversity Standards). These standards identify projects that simultaneously tackle climate change while supporting local communities, small farms and measures that protect biodiversity. They can be applied to any land management project, including projects that are also certified under the VCS Programme
