The 2022 Cleantech 50 to Watch is the fourth annual list of early-stage innovators taking action on the climate crisis. The entrepreneurs on the list are creating new technologies and business models that could solve the plastics crisis, regenerate soils, recycle building materials, automate food waste, and promote environmental and economic stewardship.

To create the list, we put together a diverse panel of over 31 early-stage innovation and investment experts. We asked them to nominate and review the companies that most impressed them and combined that information with our own nominations and research on early-stage awards. Get the complete report.

Ready to meet the innovators on the 2022 Cleantech 50 to Watch list and gain insight into the technologies and business models they’re using to take action on the climate crisis? Join us for Cleantech Forum Europe on 8-10 November 2022.
