US EPA has published Fundamentals of Successful Monitoring, Reporting, and Verification under a Cap-and-Trade Program (pdf 8 pp, 100 kB). The paper discusses several elements that were fundamental to the success of two USEPA cap-and-trade programs—the Acid Rain Program (ARP) and the NOx Budget Trading Programs (NBTP). The authors believe these elements may be useful to the design and implementation of other cap-and-trade programs both within and outside of the United States. (ISSN 1047-3289, J. Air & Waste Manage.
