Greenhouse gas emissions are one of the environmental impacts of electricity generation. Measurement of life-cycle greenhouse gas emissions involves calculating the global warming potential (GWP) of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. [1]
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
Nuclear power plants do not burn fossil fuels and so do not directly emit carbon dioxide. The carbon dioxide emitted during mining, enrichment, fabrication and transport of fuel is small when compared with the carbon dioxide emitted by fossil fuels of similar energy yield, however, these plants still produce other environmentally damaging ...
Peters and Hertwich [11] completed a MRIO study to calculate emissions embodied in international trade using data from the 2001 Global Trade Analysis Program (GTAP). After manipulation, although their numbers are slightly more conservative (EU 14%; OECD 3%; BRIC 16%; RoW 6%) than Boitier [ 5 ] the same trend is evident - developed countries are ...
The GREET model is specified in the Inflation Reduction Act of 2022 §45V [2] as the methodology to calculate the life cycle greenhouse gas emissions "through the point of production (well-to-gate)" when determining the level of tax credit for clean Hydrogen production until a successor is approved by the Secretary of the Treasury. The final ...
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]

If emissions are attributed at the point of production, then electricity generators contribute about 25% of global greenhouse gas emissions. [108] If these emissions are attributed to the final consumer then 24% of total emissions arise from manufacturing and construction, 17% from transportation, 11% from domestic consumers, and 7% from ...
