CFI/ Saving The Earth
The following activities affect the carbon footprint of individuals, according to the various calculators available:
* Car travel: depends on distance driven, fuel efficiency, and number of passengers per vehicle.
* Air travel: depends on distance and number of flights. Take-off and landing use large amounts of fuel, so two short flights produce more carbon than one long flight of comparative distance.
* Other motorised transport such as bus or train: normally counts for less per person than either car or air travel.
* Electricity use, if provided by non-renewable resources. Some calculators ask for figures from utility bills, while others estimate the amount from size of household and usage patterns (such as whether you leave equipment on standby overnight).
* Home heating: depends on fuel source and amount used.
* Food miles: how much food you buy from non-local sources.
* Diet: meat-eater, vegetarian or vegan, conventionally farmed foods or organic produce.
