Every year, international think tank Sustainia identifies innovative and groundbreaking solutions from around the world within 10 sectors. These projects and technologies are pushing the envelope of sustainable transformation.

This year, Sustainia investigated and vetted more than 1,200 innovative projects and solutions from 79 countries to create the Sustania100, a list of the 100 most inspiring solutions from this vast pool of data.

At Convergence Paris 2013, Sustainia's Christopher Sveen presented the results for the city sector, which included intelligent streetlight systems, self-sufficient buildings and wireless electric vehicle charging.
