  2. Emission - Wikipedia

    en.wikipedia.org/wiki/Emission

    Emission of air pollutants, notably: Flue gas, gas exiting to the atmosphere via a flue; Exhaust gas, flue gas generated by fuel combustion; Emission of greenhouse gases, which absorb and emit radiant energy within the thermal infrared range; Emission standards, limits on pollutants that can be released into the environment

  3. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Emission intensity is a ratio between greenhouse gas emissions and another metric, e.g., gross domestic product (GDP) or energy use. The terms "carbon intensity" and "emissions intensity" are also sometimes used. [63] Emission intensities may be calculated using market exchange rates (MER) or purchasing power parity (PPP).

    This is an accepted version of this page This is the latest accepted revision, reviewed on 13 February 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...

  6. Carbon footprint - Wikipedia

    en.wikipedia.org/wiki/Carbon_footprint

    The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...

    World map of emission intensity (kg of CO 2 per Intl$), 2018. The following list of countries by carbon intensity of GDP sorts countries by their emission intensity.Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO 2) emissions produced per unit of GDP.

  8. Net-zero emissions - Wikipedia

    en.wikipedia.org/wiki/Net-zero_emissions

    It will be quicker to reach net-zero emissions for CO 2 alone rather than CO 2 plus other greenhouse gases like methane, nitrous oxide and fluorinated gases. [22] The net-zero target date for non-CO 2 emissions is later partly because modellers assume that some of these emissions such as methane from farming are harder to phase out. [22]

  9. 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]
