Clean Development Mechanism validation is the independent evaluation of a project activity against the requirements of CDM. It is based on the project's design documentation, in particular the project's baseline, monitoring plan and compliance with relevant UNFCCC and host party criteria, to establish whether tradable credits are generated. In order to register for this scheme, all CDM projects must undergo a validation.
The Gold Standard (GS) is an independent certification standard for carbon credits generated from Clean Development Mechanism (CDM) projects or Voluntary Emissions Reduction (VER) projects.
Increasing numbers of organisations are voluntarily monitoring their greenhouse gas emissions. ISO 14064 is an international standard that provides a framework for greenhouse gas accounting and verification.
