Our tenth edition is dominated by innovations for the future of food and mobility, and a decentralized and digitized future not only for energy, but for the industrial world more generally. This is a far cry from the dominance of hardware, solar and biofuels in the inaugural Global Cleantech 100 in 2009.

Three innovative Ontario companies have made the Global Cleantech 100, a list of the most innovative and promising companies, positioned to solve tomorrow's clean technology challenges.

Nearly 13,000 companies from 90 countries were nominated for the esteemed Global Cleantech 100 list this year. Eligible companies are evaluated through a three-stage process to determine the most likely to make significant market impact over the next five to ten years. The nominations are weighted and scored to create a shortlist, which are then reviewed by CTG's expert panel.
