Welcome to The Green Ration Book
The average UK citizen creates 11 tonnes of Carbon Dioxide equivalent (CO2e)
a year. CO2e includes the effects of other greenhouse gasses as well as
the main greenhouse gas, carbon dioxide.
New UK targets aim to cut this by 80%.
Reducing these 11 tonnes by 80% gives a ration of 2.2 tonnes per year.
This makes a daily ration 1.5kg CO2.
Dividing the ration equally between categories “consumables”, “building”, “transport”
and “government”, allows 1.5kg per day.
The estimates below are for CO2e and amount of a 1.5kg daily ration.
is expressed as a time (e.g. a quarter of a daily ration is given as 6 hours).
Mangoes and Passion fruits smoothie
CO2e: 0.29kg (2 hours)
Innocent Drinks have calculated the carbon footprint of a mangoes and passion fruits smoothie here:
They give it as 0.29kg.
1kg of potatoes from Lincolnshire
CO2e: 0.20 kg (3.5 hours)
Road freight 0.03 kg (147 gm per tonne km * 200 km /1000 = 29.4 gm Co2e)
Agricultural 0.10 kg (guessed)
Cling film wrapping 56gm (8 gm plastic film at 7gm CO2e per gm)
CO2e: 0.075 kg (1.5 hours)
Walkers have calculated the carbon footprint of a bag of crisps here:
They give it as 75g.
200g Corgettes from Kenya
CO2e: 1.79kg CO2e (1 day, 2 hours)
Food Refridgeration 100
Air Freight 1350
20g Plastic packaging(at 7gm Co2e/gm) 140
Road Freight 100
Result: CO2e 1.79kg
