Global Cleantech 100
Welcome to the Global Cleantech 100, an annually-refreshed list of the top 100 private innovation companies in clean technology. Collated by combining proprietary Cleantech Group research data, with over 11,000 nominations and specific input from an expert panel, these companies represent the most innovative and promising ideas in cleantech — the companies that are best positioned to solve tomorrow’s clean technology challenges.
How the List Comes Together
Every year since 2009, we have put together the Global Cleantech 100 list following our Methodology to answer the question: According to the world’s cleantech community, which 100 of today’s private cleantech companies are the most likely to make the most significant market impact over the next 5-10 years?

We incorporate nominations from the general cleantech community as well as input from a global expert panel. Our public nominations are now closed.
Global Cleantech 100 (2009-2017)
We are currently in the process of pulling together the 8th edition of the Global Cleantech 100 list. Meantime, you can check out the previous years’ lists and download the corresponding reports below. Each year’s report is entitled “A barometer of the changing face of global cleantech innovation” because the process allows us to provide a viewpoint on which are the companies and the sub-sectors top of mind today, and why, and how has that been changing over time.
In-depth company profiles can be found on i3 Connect.
You can dive deeper into our Global Cleantech 100 companies, and explore the past five years of the Global Cleantech 100 Reports and the groundbreaking companies celebrated within.
