This is the final week for the public to vote for the winner of innovation competition FT Climate Change Challenge, organised by the sustainable development organisation Forum for the Future.
The competition has garnered interest from around the globe, with more than 300 entries.
The winning entry, which will be announced on 3 April, will receive $75 000 (£51 000) and commercial support in bringing it to market.
The five shortlisted entries that aim to tackle climate change include a solar-powered cardboard stove for use in rural Africa, created by Kenya’s Kyoto Energy, and evaporating tiles that provide a low-carbon alternative to air-conditioning systems, designed by the UK’s Loughborough University.
A lightweight aerodynamic cover for lorry wheels that reduces drag, and a feed-additive given to livestock to control flatulence and so reduce methane production, as well as a giant industrial microwave that turns carbon produced by trees into charcoal, complete the shortlist.
Business and sustainability leaders Jonathon Porritt, Leon Sandler, Eileen Claussen, Mark Hurd, Sir Terry Leahy, Dr Rajendra K Pachauri, Sir Richard Branson and Lionel Barber comprise the judging panel who will select the overall winner.
