Ineffectual things some bands do ...
Ash and others may clap themselves on the back for offsetting their flights, but this is an oft-discredited method of compensating the environment for the damage already done.
KT Tunstall, Bonnie Raitt and others have taken bio-diesel buses on tour, but biofuels are not a viable long-term alternative to carbon-based fuels as they require vast tracts of land.
One of those “greenwash” gestures that some promoters encourage. They may add to a festival’s feel-good factor, but plastic beer cups are a tiny percentage of a rock festival’s carbon footprint.
It hardly makes sense for a band to fly its entourage all over the world when perfectly good expertise is available for hire in each territory. As for Björk’s 40-strong entourage at her last Irish performance – that’s just wrong.
