New runway for Brisbane airport

Andrew Bartlett talks about CO2 emissions implications of an extended runway at Brisbane airport.

I am a lifelong resident of inner Brisbane, and I can understand why people living in the vicinity of the airport may be concerned about the possible noise impacts of an extra runway. … However, I think a much bigger issue with the airport expansion, which has the potential to affect absolutely everybody, is what the predicted huge increase in the number of flights will mean for greenhouse emissions.

… According to the calculator on this site, every time I fly from Brisbane to Canberra I am responsible for the equivalent of 0.67 tonnes of emissions, which I can purportedly ‘neutralise’ by paying $14.16 towards funding climate friendly projects. I am not sure of how scientific sites like this are, but offsetting emissions is the main way at the moment to reduce the overall impact of air travel.
