Yeah, I'm aware of his company, Copenhagenize Design. Seems to be primarily involved in communications, media, and advocacy. Nothing wrong with that of course, and it fits with Colville-Andersen's expertise and background in media and communications. How he can then claim to be an "Urban Design Expert", or even an "Urban mobility expert" is something of a mystery.
On this basis, you, paulmilne, can claim to be an "Urban mobility expert" as you happen to ride a bike in a city, and you presumably advocate for more bicycle friendly urban space. You may not, of course, be "an influential and much sought after keynote speaker:, which Colville-Andersen is, it would appear. Which is fine.
He's good at marketing, at spreading ideas from his home city Copenhagen internationally, and is media savvy. Which is all good, we need people like that. If his company can do some good while making some nice consultancy fees that's great. It's the self-aggrandising claims about his "expertise" I take issue with.
