The Energy Policy Act of 1992, among other provisions, created a voluntary program whereby U.S. companies and other organizations may report the results of their efforts to reduce, avoid, or sequester emissions of greenhouse gases, including carbon dioxide, methane, and several engineered gases. The Energy Information Administration (EIA) is mandated to gather and publish data on such efforts since 1994 and has just released the latest available data in Voluntary Reporting of Greenhouse Gases 2000.
In 2000, 222 U.S. companies and other organizations (hereafter "reporters") reported that they undertook 1,882 projects to reduce or sequester greenhouse gases. These efforts produced reported results that are grouped in four general categories:
- Direct reductions (emissions reductions from any sources owned wholly or in part, or leased, by the reporting company), which produced reported reductions of 187 million metric tons carbon dioxide equivalent (MMTCO2E) (see table);
- Indirect reductions, which are from sources not owned or leased by the reporter but which occur wholly or in part because of the reporter's activities (61 MMTCO2E);
- Sequestration, the fixation of atmospheric carbon dioxide in a carbon sink through biological or physical processes such as photosynthesis (9 MMTCO2E); and
- Unspecified reductions, reported reductions not categorized as either direct or indirect (12 MMTCO2E).
Direct and indirect reductions can be further broken down according to which of two baselines was used to calculate them, either emission levels in a particular prior year or hypothetical projected emission levels in the absence of reduction efforts. In 2000 over 80 percent of the 187 MMTCO2E total direct reductions, and 92 percent of the indirect reductions, were reported using the latter baseline.

Source: Energy Information Administration.Electric power sector reporters accounted for 1,287 (68 percent) of the reported projects in 2000; 462 of the projects (nearly all originating in the electric power sector) were related to the generation, transmission, or distribution of electricity while another 424 were related to energy end use. Industrial reporters accounted for 206 projects, agricultural and forestry organizations for 174, and alternative energy providers for 203.
Electric power sector projects accounted for 133 MMTCO2E in direct reductions. Energy end-use projects totaled about 20 MMTCO2E in direct reductions. Carbon sequestration projects accounted for 9 MMTCO2E, and methane abatement projects 29 MMTCO2E, of direct reductions. EIA no longer calculates the total of direct and indirect reductions because of the potential for double-reporting.
