    Life cycle CO 2 equivalent (including albedo effect) from selected electricity supply technologies according to IPCC 2014. [3] [4] Arranged by decreasing median (g/kWh CO 2 eq) values. Technology Min. Median Max. Currently commercially available technologies Coal – PC: 740: 820: 910 Gas – combined cycle: 410: 490: 650 Biomass – Dedicated ...

  3. Greenhouse gas inventory - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_inventory

    It hence offers a description of the global supply chains of products consumed". [15] From this, assuming regional- and industry-specific data for CO 2 emissions per unit of output are available, the total amount of emissions for the product can be calculated, and therefore the amount of emissions the final consumer is allocated responsibility ...

  4. Emission intensity - Wikipedia

    en.wikipedia.org/wiki/Emission_intensity

    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).

  5. Carbon accounting - Wikipedia

    en.wikipedia.org/wiki/Carbon_accounting

    In the context of GHG accounting, RECs are often used to adjust estimated Scope 2 emissions. In a typical case, a company would calculate its Scope 2 emissions using its electricity consumption and a grid emissions factor. Companies that purchase RECs can use them to lower the average emissions factors included in their inventories.

    Other tools such as labeling/environmental disclosure, Renewable Portfolio Standards (RPS) and Renewable Energy Credits (RECs) attributes are supported by eGRID data. States also rely on eGRID data for electricity labeling (environmental disclosure programs), emissions inventories, and for policy decisions such as output based standards.

  7. GREET Model - Wikipedia

    en.wikipedia.org/wiki/GREET_Model

    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 ...
