Carbon footprint

  1. 1. CARBON FOOTPRINT
  2. 2. No, I don’t know anything. I’m not sure. Yes, I do. Do you know anything about Carbon Footprint?
  3. 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. 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. 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. 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. 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. 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. 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. 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. 11. Your carbon footprint Now lets see what your carbon footprint is....
  12. 12. How do you feel about your carbon footprint?
  13. 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. 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. 15. Let’s Go Green!!!
