I'm not in London this week, but I've been following the Extinction Rebellion with interest, especially having spent most of my career playing a small part in helping corporations reduce their energy consumption and improve environmental impact. There's a lot that needs to be done, but in my opinion, the priority is not in the UK but elsewhere - and that should be a clarion call for startup businesses that are developing solutions to move immediately to international expansion. I've made a video with my thoughts - what are yours?
