2008 Mclaren F1 CarLet’s compare an F1 car to a typical car in the UK which produces about 160 g/km, and over a year (10,000 miles) will produce about 2.56 tonnes of CO2.

According to Wikipedia a typical F1 burns 75 litres of fuel per 100km raced. Based on figures for petrol (which is a reasonable proxy of race fuel), 0.75 litres of fuel burnt per km equates to a CO2 output of 1737 g/km. And over a race season using approx 100,000 litres of the stuff, that’s 231 tonnes of CO2. Per car. And each team has 2. So for fuel alone, before the costs of flying to races, support vehicles and the number of cows required to furnish Max Mosley’s “special” wardrobe, that’s about 463 tonnes per team. I wonder if they carbon offset?

At least they’re becoming hybrids for the 2009 season…

So here in London, Boris Johnson has announced he’s going to create a cycle scheme along the lines of the Velib in Paris. He may look like Worzel Gummidge’s mad cousin, but I Boris, outside a barber's yesterdaysuspect he’s a very smart cookie. Good on him.

Now, if this scheme were to take off, then potentially less buses or tube trains would be needed (as if there are enough already! – ed), and this could have a beneficial impact on the carbon footprint of London. So what’s might that be?

Well, 6,000 cycles are going to be used in zone 1, so let’s assume that roughly:

  • 25% replace tube journeys* @ 65.0 g/km
  • 25% replace bus journeys* @ 81.8 g/km
  • 25% replace cab journeys @ 172 g/km
  • 25% replace walking journeys @ 0 g/km

Assuming that any bike in use is averaging 5km / hr through central London, and that at any one point averaged throughout the day (more during the day and less at night of course), 30% of the cycles are in use. Then we can assume that at any point then we can assume that 1800 of them are being crashed by lost tourists, and 9000 km being cycled every hour. Over a day that’s 216,000 km pedalled, or 17.2 tonnes of carbon offset every day. That’s pretty good Boris.

However, does anyone else have a sneaking suspicion that the majority of Boris’s bikes will disappear by the truckload and end up in Albania ?
