Forests burn, glaciers melt and one million species face extinction. Can we humans save the planet from ourselves? In a new film, alumni Sir David Attenborough and Dr Jane Goodall DBE, and leading Cambridge University researchers, talk about the urgency of the climate crisis – and some of the solutions that will take us towards zero carbon. If we are to avoid climate disaster we must sharply reduce our carbon dioxide emissions starting today – but how? Cambridge researchers describe their work on generating and storing renewable energy, reducing energy consumption, understanding the impact of climate policies, and probing how we can each reduce our environmental impact. We hear how the ambitious new programme Cambridge Zero is bringing together ideas and innovations to tackle the global challenge of climate catastrophe – and inspiring a generation of future leaders – and how the University is looking at its own operations to develop a zero carbon pathway for the future.
