Carbon Dioxide & Foreign Holidays

It's common to hear criticism of our foreign holidays, and the global warming they might be causing. It's less common to do a few sums to see if our holidays really are affecting the temperature of the planet.

I had a look at the Boeing website and found out some things about Jumbo Jets.

A 747 typically weighs about 164 tonnes, empty. Its maximum take-off weight is 340 tonnes, so for a really long flight, fuel plus passengers weigh as much as the plane itself - about 180 tonnes.

On a typical flight, with 500 people on board, and a 10 hour journey, 80 tonnes of fuel will be used.

This means each person uses 80/500 tonnes of fuel - about a sixth of a ton.

For kerosene, one tonne of fuel produces about 3 tonnes of carbon dioxide.

So each passenger's fuel produces half a tonne of CO2.

This compares with an annual carbon dioxide "production" of about 4 tonnes for each man, woman and child in Britain.

Another half tonne of CO2 is produced on the way back.

So a person's own "CO2 production" goes from 4 tonnes to 5 tonnes as a result of a foreign holiday.
