Can tourism ever be green?

It's one of those double edged swords, tourism brings wealth and changes lives often in some of the poorest parts of the world, yet the effect of tourists can be damaging to the environment.

London is a world tourism hub with more than 2.5 million international visitors last year, let alone the thousands of Brits who visit the Capital from around the UK. One of the must do things is to jump on a sightseeing bus and cruise the streets and one company, Tootbus, aims to make that tourist experience as low carbon as possible.

I joined Gavin Brooking, the MD of Tootbus on a tour of the city aboard an EV bus and explored his desire to retrofit old buses and make them all low emission, watch and listen and don't forget to subscribe.
