I’ve been in the world of sustainability for a very long time – but it’s hard to recall a time when things have felt quite so urgent.

Top of my mind right now is my new book, The World We Made (Alex Mckay's Story from 2050), which launched in late 2013.

The World We Made presents a credible vision of the world in 2050 - a world that is connected, collaborative and genuinely sustainable. This is the biggest thing I’m working on at the moment. We simply have to change the ‘mood music’ in terms of the way people feel about sustainability, and that means that everything we do in Forum for the Future is about positive solutions to today’s converging sustainability challenges.
