Since 1996, APX has been leading both the energy and environmental markets in the United States and internationally. Their focus on continual innovation and intense market awareness has enabled clients to remain at the forefront of rapidly evolving energy markets around the world.  

APX’s core expertise lies in the development and implementation of renewable energy and carbon offset instruments and standards worldwide.  This experience, coupled with the strong cooperation of market participants, has led to the launch of the registry as a best-in-class solution for issuing, tracking, and retiring the environmental attributes associated with renewable energy production. 

APX provides complete coverage for renewable energy certificate (RECs) creation, management, and transactions across North America to facilitate the continued growth of clean energy generation and usage. 

Leveraging 20 years of experience as the leading provider of REC tracking solutions in both the voluntary and compliance markets in every region of the United States, APX created two separates but equally robust REC tracking platforms to offer complete worldwide REC portfolio coverage. Our North American Renewables Registry (NAR) covers REC tracking across all of North America, while the Tradable Instrument for Global Renewables (TIGR) covers the rest of the world. 

APX created the Tradable Instrument for Global Renewables (TIGR) Registry as an online platform for tracking and transferring Renewable energy certificates (RECs), enabling developers to generate, verify, and sell RECs. RECs track all environmental attributes of 1 megawatt hour of renewably generated power allowing you to demonstrate your sustainability achievements in a tangible and verifiable way. 

The global demand for renewable energy is growing by the day, with increasing numbers of corporate and industrial energy consumers who want to buy renewable power using a credible tracking system. The TIGR Registry enables transparent, secure, and reliable tracking of RECs, backed by APX quality standards.
