Conceptually, a line drawn to encompass the emissions sources and sinks to be evaluated in an entity- level report. The reporting of greenhouse gas emissions, emission reductions, and carbon sequestration for an entire entity. The techniques, including key assumptions and data sources, used by the reporter to derive the reported emissions, emission reductions, or sequestration. All actions outside of the United States, its territories, and trusts. The entire set of sequential processes or stages involved in the utilization of fuel, including extraction, transformation, transportation, and combustion.
Emissions generally occur at each stage of the fuel cycle.
The substitution of one type of fuel for another. A zone of rubble created when the roof of a coal mine collapses behind the mining operations. A popular term used to describe the roles of water vapor, carbon dioxide, and other trace gases in keeping the Earth's surface warmer than it would otherwise be. These radiatively active gases are relatively transparent to incoming shortwave radiation but are relatively opaque to outgoing long-wave radiation. The latter radiation, which would otherwise escape to space, is trapped by these gases within the lower levels of the atmosphere.
