The Voluntary Carbon Standard (VCS) provides quality assurance for the world’s carbon markets through its global program for approval of credible voluntary carbon offsets, or voluntary carbon units (VCUs).

In 2007, VCUs reportedly represented nearly one-third of the global voluntary carbon market, making it the most widely used carbon offset standard.

Edwin Aalders, acting CEO of the VCS Association, said: The VCS Project Database provides a critical central resource for market participants to supply, find, and buy VCUs, and access all related documentation. Through its track record, APX has demonstrated its strong technology and service capabilities, which are required to address the data management and transaction needs of carbon markets and financial markets worldwide.
