Presentation Transcript

  1. Food and Greenhouse Gas emissions Using information taken from...

  2. Carbon Dioxide and Climate Change • CO2 is a greenhouse gas. • Some gases are lighter than air e.g. Helium. • CO2 is heavier than air. • How big do you think a kg of CO2 is?

  3. Greenhouse gases Carbon Dioxide CO2 Methane CH4 Nitrous Oxide N2O 1kg CO2=1 kg CO2e 1kg CH4 =25 kg CO2e 1Kg N20 =300 kg CO2e

  4. Work with a partner • Order food and drink cards by ‘carbon intensity’, with the item that emits the most CO2e at the top and the least at the bottom. • Now take a pile of footprint cards and match the food and drink with the amount of CO2e you and your partner think it produces.

  5. Additional information to help you, • Remember that Methane is a 25 times more potent green house gas than CO2, Methane is produced by cows in the production of meat and milk based products. • Assume the cup of tea is made with milk and the normal practice of boiling around double the water needed. • Assume the carrots are average- grown in UK, non organic, supermarket bought. • You bought the tomatoes in March (this makes a big difference as they are grown in a heated greenhouse).

  6. A banana

  7. 80g CO2e How many grams of CO2 e for a bunch of 6 bananas?

  8. A mug of tea

  9. A large Latte 340g CO2e 71g CO2e No milk and boil only 1 mug of water 20g CO2e

  10. 1kg of carrots

  11. 300g CO2e Estimate how much for 1 carrot.

  12. A 500ml bottle of Water

  13. 160g CO2e What if you had a bottle of water every day for a year?

  14. An Ice cream (from an ice cream van)

  15. What if you had an ice cream every week for a year? 500g CO2e

  16. A cheeseburger

  17. 2.5kg CO2e How many bananas have the equivalent emissions?

  18. 1kg of organic vine tomatoes (UK grown)

  19. 50kg CO2e

  20. Talk with your partner... • How can we trust this information? • What have you learnt? • What might you think about in the future? • What will you tell others about what you’ve learnt?
