  • 2. No, I don’t know anything. I’m not sure. Yes, I do. Do you know anything about Carbon Footprint?
  • 3. Carbon Footprint Carbon Footprint is the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of CO2.
  • 4. What is Greenhouse Gas? Gases that trap heat in the atmosphere. Some occur from nature and others from human activities. Principal greenhouse gases entering the atmosphere from human activities are: oCarbon dioxide (CO2) oMethane (CH4) oNitrous Oxides (N2O) oFluorinated gases (HFCs & PFCs)
  • 5. Direct vs. indirect emissions • Direct emissions of an item – Manufacturing process – Transportation of item to retailer • Indirect emissions – Everything else – Example: offices in the factory use paper clips made of steel that were mined and have their own carbon footprint
  • 6. Context for numbers • The average American has a carbon footprint of 28 tons CO2e / year 313,914,040 x 28= 8’789’593,120 (1.5 Gt) • World GHG emissions are 34 Gt* CO2e / year • The global average carbon footprint is ~6 tons CO2e / year / person Peru: 1.6 tons CO2e/year / person *Gt: Gigatonnes (5.9 billion tonnes)
  • 7. Let’s try… The carbon footprint of manufacturing a new car is ____ compared to the carbon footprint of driving that car over its lifetime 1. Very small 2. Roughly equivalent 3. Very large
  • 8. A new car • Citroen C1 – 6 tons CO2e • Ford Mondeo – 17 tons CO2e • Land Rover Discovery, top of the range – 35 tons CO2e • The CO2e emissions associated with producing the car are comparable to the CO2e emissions out of that car’s tailpipe over its lifetime
  • 9. Using a cell phone • Depends on how often you use it • Components of footprint – Manufacturing of phone • 16 kg (35 lbs) CO2e – Power over 2 years • 6 kg (13 lbs) CO2e – Energy required to transmit calls across network • 66 kg (146 lbs)
  • 10. Using a cell phone • 1 minute cell-to-cell phone call has the same carbon footprint as an apple = * Texting is a much lower carbon option.
  • 11. Your carbon footprint Now lets see what your carbon footprint is....
  • 12. How do you feel about your carbon footprint?
  • 13. Let’s look at our carbon footprint and the ways we can try and reduce it. Ok so we know what our carbon footprint is... What can we do about it?
  • 14. My Carbon footprint Reduce the amount we use our car, turn off the lights, buy locally produced goods , recycle your waste, try solar panels. Reduce our CO2 emissions This will reduce the amount of greenhouse gasses, which in turn reduces global warming.
  • 15. Let’s Go Green!!!
