These credits were pruchased though the Chicago Climate Exchange (CCX). The CCX has strict requirements for offset projects which are intended to meet or exceed the requirements of international Clean Development Mechanism (CDM) projects. After being reviewed by the CCX committee, the issuances are also reviewed by the National Association of Securities Dealers (NASD) for assurance as a valid financial instrument. With this many checks including the requirement that an independent third-party verifier attest to and visit the project, make the credits we choose very high quality. Although, the issue goes deeper than simple verification and credibility. The real question is whether the offset being offered represents a real greenhouse gas reduction that is influenced by the availability of carbon credit money and a concern for the related issues, rather than a "business as usual" project as you put it. The offset providers and the CCX spend a great deal of time examining the "base case". Providers also examine whether typical business practices or government regulation could possibly have played a part in the project decisions.
