The International Working Group on Environmental Technology Verification (IWG-ETV) was founded in 2007 with the intent to develop a common approach to verification so that, in future, participating countries would be able to mutually recognize one another’s verifications.
In 2013, the International Organization for Standardization (ISO) accepted a proposal for a new standard on ETV and drafting of ISO 14034 began. The committee responsible for this important standard is TC 207. The standard was published on November 15, 2016.
Additional details on ISO 14034 can be found on ISO’s website.
