Sustainability is one of the buzzwords of the age, the mantra of right-on eco-warriors, but the Sustainable Futures exhibition, in London’s Design Museum, explores it with a focus on innovation, fleshed out with spectacular images.

The scope and detail is exhaustive – find out which of the world’s cities is the most sustainable, and how architects reduced their carbon footprint by building the California Academy of Sciences partially underground.
