How many hours in the last 12 months on personal air travel to places outside Europe? Help

This shouldn't include work flights, as for the purposes of calculating your footprint, business travel forms part of your employer's footprint not your own.

Did you know:

One return flight to Australia uses as much energy as it takes to heat and power your home for six years.

Cutting down by one long-haul flight a year could reduce your travel footprint by 24%.

Science now clearly suggests that flying has an even greater impact on climate change than was previously thought. Changes to cloud formation and exhaust emissions at high altitudes mean aviation's total impact is likely to be two to four times that of its CO2 alone. Having analysed the latest science, WWF multiplies CO2 emissions on all flights by 2.7. This is a little higher than the government's figure, but we believe it is justified since the government takes no account of the impact of additional cirrus clouds triggered by planes - potentially a large source of warming.
