Zachariah invented Carbon Hero, a mobile-based application to give users their personal environmental carbon dioxide ‘footprint’ when travelling. With almost no user input, Carbon Hero, with its specialist database and algorithm, determines the environmental impact of different forms of transport. Carbon Hero won the Prague/Czech Republic regional prize in the European Satellite Navigation 2007 Competition, sponsored by ESA’s Technology Transfer Programme.
