The Environmental Tracking Network (ETNNA) is a voluntary association of certificate tracking systems, registries, regulators and interested market participants that are vested in preventing double-counting and promoting harmonization among certificate tracking systems and emissions registries in North America. Such harmonization will encourage trade, create a common currency for certificates, prevent double counting, and support new and emerging markets.
