Cheeseburger

CO3e: 4.85 kg (3 days 5 hours)

Jamais Cascio has calculated the carbon footprint of a cheeseburger here:

http://www.openthefuture.com/cheeseburger_CF.html

“That’s a total of 3.6-6.1 kg of CO2-equivalent per burger”

He shows his calculations and gives some references.

Should we average his figure to 4.85 kg?

Bottle of Bubbly

CO2e: 1.31 kg (16 hours)

Initially estimated as 9.41 kg

1.1 kg Glass bottle 9.20 kg Co2
Freight London 0.21 kg Co2 (1.1Kg * 0.19 / 10)
No figure for the production of the wine was included.

The available data on the carbon footprint of glass iscontradictory.
More research needed.

Revised to 1.31kg on changes to “Carbon footprint of 1kg General Glass”

Newspaper

CO2e: 0.17kg (3 hours)

Innocent Drinks mention the carbon footprint of a copy of the Daily Mirror here:

http://innocentdrinks.typepad.com/innocent_drinks/2007/03/sustainability.html

They give it as 0.17kg.

Where do they get their data?

Result : “CO2e 0.17kg”

4 apples

CO2e: 0.12kg (2 hours)

Innocent Drinks mention the carbon footprint of an average apple here:

http://innocentdrinks.typepad.com/innocent_drinks/2007/03/sustainability.html

They give it as 0.03kg. So 4 apples 0.12kg CO2e

Where do they get their data?

Result: “CO2e  0.12kg”
