  2. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.

  3. Life-cycle greenhouse gas emissions of energy sources

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

    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]

  4. 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 ...

  5. Transient climate response to cumulative carbon emissions

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

    [7] [8] [2] This means that for specific amount of cumulative CO 2 emissions, a known global temperature change (within a range of uncertainty) can be expected, which indicates that holding global temperature change to below specific thresholds is a problem of limiting cumulative CO 2 emissions, leading to the idea of a carbon budget. [2] [9] [3]

  6. Useful conversions and formulas for air dispersion modeling

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

    If a gaseous emission sample is analyzed and found to contain water vapor and a pollutant concentration of say 40 ppmv, then 40 ppmv should be designated as the "wet basis" pollutant concentration. The following equation can be used to correct the measured "wet basis" concentration to a " dry basis " concentration: [ 3 ]

  7. Climate stabilization wedge - Wikipedia

    en.wikipedia.org/wiki/Climate_stabilization_wedge

    The approach presents global warming as a problem which can be attacked using commercially available technologies to reduce CO 2 emissions. Selecting a set of mitigation strategies to create a stabilization triangle is a planning framework for identifying possible interventions for the reduction of emissions. The objective is to stabilize CO

  8. Special Report on Emissions Scenarios - Wikipedia

    en.wikipedia.org/wiki/Special_Report_on...

    Overall global GDP will grow by a factor of between 5–25 in the emissions scenarios. These emissions scenarios are organized into families, which contain scenarios that are similar to each other in some respects. IPCC assessment report projections for the future are often made in the context of a specific scenario family.

  9. Voluntary Emission Reduction - Wikipedia

    en.wikipedia.org/wiki/Voluntary_Emission_Reduction

    Verified Emission Reductions are usually created by projects which have been verified outside of the Kyoto Protocol. One VER is equivalent to 1 tonne of CO 2 emissions. [3] Through these schemes, industries and individuals voluntarily compensate for their emissions or provide an additional contribution to mitigating climate change.
