It's been a busy week at the UNGA! We signed The Climate Pledge with Jeff Bezos from Amazon, saw world leaders stepping up their climate ambition, heard Greta Thunberg's scathing speech, and even had time to fire up the ol' anti-echo machine. Later in the episode we catch a few minutes with Sir Richard Branson, the man behind Virgin. We get into the green innovations he is working on, and discuss his bigger vision on how airline travel becomes sustainable.
