Time interview

Branson answers questions from Time readers, including one on running an airline while promoting environmental causes:

I think it’s because I own an airline and I’m running a dirty business that I decided to do something about it. I could either sell the airline to somebody else and those planes would keep on flying, and emitting, damaging the environment, or I could pledge 100% of the profit of the airlines, which I have done, and which will amount to about $3 billion over the next few years, into developing new, clean fuels.
