Greenhouse Gas Emission Verifiers

Different mechanisms have been put in place in the fight against climate change to reduce emissions of greenhouse gases (GHGs). To function correctly, many of these mechanisms require a reliable, internationally comparable process to quantify emissions. This activity is carried out by verifiers who must be competent in the performance of this task. The international standard established for accreditation bodies to evaluate this competence is UNE EN/ISO 14065 Requirements for greenhouse gas validation and verification bodies for use in accreditation or other forms of recognition.

One system intended to reduce GHG emissions is the European Union Emissions Trading System, which is a key element of Europe's climate change strategy and a basic instrument for achieving the aims of reducing emissions at the lowest possible cost.

Proof of the confidence that accreditation brings can be seen in the fact that the European Commission has made a clear bid for accreditation in GHG verification activities, establishing regulations whereby only verifiers accredited by a National Accreditation Body can operate both in the European Union Emissions Trading System set up a few years ago and in Verifications of Monitoring Plans and Reporting on Carbon Dioxide Emissions from maritime transport (Reg. (EU) 2015/757 to be introduced shortly).

A list of verifiers of greenhouse gases accredited by ENAC can be found in the accredited bodies section, together with all ENAC documentation relative to accreditation criteria and procedures for Verifier Accreditation in the DOCUMENTS section.
