According to the BBC, the House of Commons Environmental Audit Committee here in the UK has just recommended that taxes on air travel be increased to help fight our ever-increasing CO2 emissions. They also suggested that vehicle excise duty for vehicles which polute the most be increased even more than they have been already.
Interestingly, the Transport Minister, Stephen Ladyman, appeared to be comfortable with suggestions about increasing excise duty for high-polluting cars but expressed concern about further taxes on air travel – citing the fact that this would penalise poor people and prevent them from taking holidays abroad.
If aircraft are one of the major causes of emissions then it would appear that a reduction in flights (and passengers) is necessary. Historically, aviation fuel has not been taxed – however, it looks like that may be about to change.
