What are Greenhouse Gasses?

22 October 2013

A lot of times when people talk about being good to the earth and the environment they talk about lowering your greenhouse gas (short name is GHG) emissions or carbon footprint (nickname for greenhouse gas emissions). There are 4 different GHG emissions that come from making many of the things we use, like electricity and food. The more GHG in our air, the worse our environment will be.

Carbon Dioxide the most common GHG and is 84% of all GHG emissions.

Comes from:

  • Burning coal and oil for electricity use (why we need to TOLBY!!)
  • Transportation: Driving cars, trucks and planes.
  • Industry: Making the materials we use to build things-like cement, iron and chemicals

Methane is 20 times more potent (worse) than CO2 and the second most common GHG (9%).

Comes from :

  • Burning coal and oil for electricity use
  • Animal digestion and waste
  • Our trash decomposing in landfills

Nitrous Oxide is 300 times more potent than CO2 and is 5% of GHG.Pie chart that shows different types of gases. 84 percent is from carbon dioxide fossil fuel use, deforestation, decay of biomass, etc.  9 percent is from methane. 5 percent is from nitrous oxide and 2 percent is from fluorinated gases.

Comes from:

  • Fertilizer used to grow plants
  • Transportation: Driving cars, trucks and planes.
  • industry: Making fertilizer and some fabrics

Flourinated Gasses are 2% of the GHG and can be the most potent.

Comes from:

  • Air conditioning: Chemicals used in air conditioning for cars, buildings and refrigerators.
  • Making aluminum (like pop cans!)
  • The transportation of electricity to our homes and schools.
