  2. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    The final two columns deal with the carbon footprint of the fuel. The fourth column contains the proportion of CO 2 released when the fuel is converted for energy, with respect to its starting mass, and the fifth column lists the energy produced per kilogram of CO 2 produced. As a guideline, a higher number in this column is better for the ...

    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 ]

  5. Biodiesel - Wikipedia

    en.wikipedia.org/wiki/Biodiesel

    The amount of greenhouse gas emissions from deforestation is so large that the benefits from lower emissions (caused by biodiesel use alone) would be negligible for hundreds of years. [136] [138] Biofuel produced from feedstock such as palm oil could therefore cause much higher carbon dioxide emissions than some types of fossil fuels. [143]

  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. 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).

  8. Emissions & Generation Resource Integrated Database

    en.wikipedia.org/wiki/Emissions_&_Generation...

    The emissions information in eGRID include carbon dioxide (CO 2), nitrogen oxides (NO x), sulfur dioxide (SO 2), mercury (Hg), methane (CH 4), nitrous oxide (N 2 O), and carbon dioxide equivalent (CO 2 e). CO 2, CH 4, and N 2 O are greenhouse gases (GHG) that contribute to global warming or climate change.

    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 : [ 8 ]
