Greenhouse Gas Reporting
Since 2001, our organization has provided companies with professional assistance in filing greenhouse gas (GHG) reports with the U.S. Voluntary Reporting of Greenhouse Gases Program (Section 1605(b) of the Energy Policy Act of 1992). We hope that others of you will also turn to our Center for your GHG reporting needs. Together, we can help you prepare an accurate, complete, consistent, relevant and transparent accounting of your emission and sequestration activities.
