The Deputy Prime Minister will launch the contest before leaving the Rio+20 summit in Brazil, where he has argued for the importance of using natural resources sustainably for long-term prosperity. Under current projections, by 2030 the world will need at least 50% more food, 45% more energy, and 30% more water, and this will need to be produced without further damaging the environment. Deputy Prime Minister Nick Clegg said: "When it comes to green innovation, Britain is a world leader. The 'green' sector is worth 8 per cent of UK GDP — the largest proportion of any of the leading industrial G20 nations — and employs almost 940,000 people - up 2.8% from last year. Sales in the green economy are also growing at a rate of 4.7%. "Now we want the very best of Britain's green talent to set their minds to some of the toughest challenges facing the country today — how to keep bills down for households and businesses and ensure we manage our food, water and energy supplies more sustainably."
