  1. Greenhouse Gas Emissions

    Slide 1 - Greenhouse Gas Emissions

  2. Types of Greenhouse Gases

    Slide 2 - Types of Greenhouse Gases

    • Carbon dioxide (CO2)
    • Methane (CH4)
    • Nitrous oxide (N2O)
    • Fluorinated gases
    • Hydrofluorocarbons
    • Perfluorocarbons
    • Sulfur hexafluoride
  3. US Greenhouse Gas Emissions in 2012

    Slide 3 - US Greenhouse Gas Emissions in 2012

  4. Carbon dioxide (CO2)

    Slide 4 - Carbon dioxide (CO2)

    • Burning fossil fuels
    • Certain chemical reactions
    • CO2 removal is absorption of plants
  5. Methane (CH4)

    Slide 5 - Methane (CH4)

    • Livestock
    • Agriculture
    • Transport of coal, natural gas, and oil
    • Decay of organic material in landfills
  6. Nitrous oxide (N2O)

    Slide 6 - Nitrous oxide (N2O)

    • Agriculture
    • Industrial activity
    • Combustion of fossil fuels and solid waste
  7. Fluorinated Gases

    Slide 7 - Fluorinated Gases

    • Powerful greenhouse gases
    • Released in smaller quantities, but are very potent
    • AKA High Global Warming Potential gases
    • “High GWP gases”
  8. Concentration or Abundance of Greenhouse Gases

    Slide 8 - Concentration or Abundance of Greenhouse Gases

    • Amount in the air
    • Measured in parts per million, parts per billion, and parts per trillion
    • 1 part per million = one drop diluted in 13 gallons of liquid
  9. How do the Gases Remain in the Atmosphere?

    Slide 9 - How do the Gases Remain in the Atmosphere?

    • Depends on the gas
    • Ranges from a few years to thousands of years
    • Gases mix well
  10. How Strongly do the Gases Impact Global Temperature?

    Slide 10 - How Strongly do the Gases Impact Global Temperature?

    • Some are better at warming than others
    • Global Warming Potential (GWP) has been calculated for each greenhouse gas
