Global challenge to unearth sustainability innovations

Cambridge University’s Institute for Manufacturing is hosting the finals of the Global Maker Challenge – a competition to find innovators and makers with solutions to some of the world’s most pressing sustainability problems. The June 4 event will feature a panel of sustainability experts from Cambridge.
The panellists from the University of Cambridge include Professor Sir Mike Gregory, former head of the Institute for Manufacturing; Dr Shailaja Fennell from the Centre for Development Studies; and Howard Griffiths from the Department for Plant Sciences.
It also includes Justin Highstead from Gatsby Africa, Belinda Bell from Cambridge Social Ventures and Dr Lara Allen from Cambridge-based Centre for Global Equality.
More than 1,100 entries were submitted from entrepreneurs around the world from over 80 countries including the UK.
Four main categories include sustainable cities, sustainable energy, rural transformation and zero hunger, and digital literacy – seeking innovations which address the global issues identified in the United Nations Sustainable Development Goals.
The Global Maker Challenge is organised by The Mohammed bin Rashid Initiative for Global Prosperity, in partnership with eight United Nations agencies.
The winner of the Global Maker Challenge will be chosen at the Cambridge event and announced in a ceremony in Yekaterinburg in Russia in July. Here are the finalists in categories.
