  2. Landfill gas - Wikipedia

    en.wikipedia.org/wiki/Landfill_gas

    Landfill gases have an influence on climate change. The major components are CO 2 and methane , both of which are greenhouse gases . Methane in the atmosphere is a far more potent greenhouse gas, with each molecule having twenty-five times the effect of a molecule of carbon dioxide.

  3. Landfill gas utilization - Wikipedia

    en.wikipedia.org/wiki/Landfill_Gas_Utilization

    Landfill gas is cheaper than natural gas and holds about half the heating value at 16,785 – 20,495 kJ/m3 (450 – 550 Btu/ft3) as compared to 35,406 kJ/m3 (950 Btu/ft3) of natural gas. [13] Boilers, dryers, and kilns are used often because they maximize use of the gas, limited treatment is needed, and the gas can be mixed with other fuels.

    This is an accepted version of this page This is the latest accepted revision, reviewed on 24 January 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 ...

  5. Regulation of greenhouse gases under the Clean Air Act

    The court further ruled that "policy judgments have nothing to do with whether greenhouse gas emissions contribute to climate change and do not amount to a reasoned justification for declining to form a scientific judgment." In EPA's view, this required the agency to make a positive or negative endangerment finding under Section 202(a) of the CAA.

  6. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    This provides a picture of the varying contributions of different types of economic activity to climate change, and helps in understanding the changes required to mitigate climate change. Greenhouse gas emissions can be divided into those that arise from the combustion of fuels to produce energy, and those generated by other processes.

    Therefore, any comprehensive plan of adaptation to the effects of climate change, particularly the present and future effects of climate change on agriculture, must also consider livestock. [85] [86] Livestock activities also contribute disproportionately to land-use effects, since crops such as corn and alfalfa are cultivated to feed the ...

    Therefore, any comprehensive plan of adaptation to the effects of climate change, particularly the present and future effects of climate change on agriculture, must also consider livestock. [33] [34] Livestock activities also contribute disproportionately to land-use effects, since crops such as corn and alfalfa are cultivated to feed the ...

  9. Carbon dioxide removal - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_removal

    Planting trees is a nature-based way to remove carbon dioxide from the atmosphere, however the effect may only be temporary in some cases. [1] [2]Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO 2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products.
