  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 ...

    Chart was requested by User:Chidgk1 at the Graphics Lab Illustration Workshop; Uploader created chart manually, using Microsoft Excel to assemble the SVG code. Technical note: SVG code for charts like this can be automatically generated by the "Variable-width bar charts" spreadsheet linked at User:RCraig09/Excel to XML for SVG.

  4. Life-cycle greenhouse gas emissions of energy sources

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

    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 material and fuel mining through construction to operation and waste management.

  5. List of countries by greenhouse gas emissions - Wikipedia

    They are measured in carbon dioxide-equivalents over a 100-year timescale. The Intergovernmental Panel on Climate Change (IPCC) 6th assessment report finds that the "Agriculture, Forestry and Other Land Use (AFOLU)" sector on average, accounted for 13–21% of global total anthropogenic GHG emissions in the period 2010–2019.

    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.

  7. Representative Concentration Pathway - Wikipedia

    en.wikipedia.org/wiki/Representative...

    RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.

  8. List of countries by carbon dioxide emissions per capita

    en.wikipedia.org/wiki/List_of_countries_by...

    The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions. [6]

  9. Second-generation biofuels - Wikipedia

    en.wikipedia.org/wiki/Second-generation_biofuels

    Carbon-based materials can be heated at high temperatures in the absence (pyrolysis) or presence of oxygen, air and/or steam (gasification). These thermochemical processes yield a mixture of gases including hydrogen, carbon monoxide, carbon dioxide, methane and other hydrocarbons, and water. Pyrolysis also produces a solid char.
