  2. 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 ...

  3. Useful conversions and formulas for air dispersion modeling

    en.wikipedia.org/wiki/Useful_conversions_and...

    Correcting to a reference carbon dioxide content [ edit ] The following equation can be used to correct a measured pollutant concentration in an emitted gas (containing a measured CO 2 content) to an equivalent pollutant concentration in an emitted gas containing a specified reference amount of CO 2 : [ 5 ]

  4. Kaya identity - Wikipedia

    en.wikipedia.org/wiki/Kaya_identity

    The Kaya identity is a mathematical identity stating that the total emission level of the greenhouse gas carbon dioxide can be expressed as the product of four factors: human population, GDP per capita, energy intensity (per unit of GDP), and carbon intensity (emissions per unit of energy consumed).

  5. Greenhouse gas inventory - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_inventory

    These tiers indicate which method of emissions calculations is used from the IPCC 1996 Guidelines. [12] Activity GHG IPCC Tier Method used to estimate emissions Public electricity and heat production: CO 2: 2: An emissions factor is applied to fuel consumption data from DUKES. Some data are also collected from individual point sources at ...

  6. 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).

  7. Transient climate response to cumulative carbon emissions

    en.wikipedia.org/wiki/Transient_climate_response...

    [9] [3] [17] A carbon budget is “the maximum amount of cumulative net global anthropogenic carbon dioxide (CO 2) emissions that would result in limiting global warming to a given level with a given probability, taking into account the effect of other anthropogenic climate forcers”.

  8. Idealized greenhouse model - Wikipedia

    en.wikipedia.org/wiki/Idealized_greenhouse_model

    The equilibrium solution with ε=0.82. The increase by Δε=0.04 corresponds to doubling carbon dioxide and the associated positive feedback on water vapor. The equilibrium solution with no greenhouse effect: ε=0. The infrared flux density out of the top of the atmosphere is computed as:

  9. Life-cycle greenhouse gas emissions of energy sources

    en.wikipedia.org/wiki/Life-cycle_greenhouse_gas...

    The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from ...
