The government’s climate change advisers have recommended banning air miles reward schemes because they “stimulate demand” for excessive flying, according to The Daily Mail (14 October).

My limited experience of air miles is that only a small percentage are allowed per flight, meaning that most passengers would be fare paying. Would a whole flight be cancelled due to a handful of air miles passengers?

Although we should not be complacent, the current reaction is out of proportion. China has 870 coal fired power stations and India has 139; surely this puts the whole carbon emission problem into perspective?
