To get the ball rolling, here are my green (some more than others) crowdfunding flutters. Those which are UK companies (the majority) have always been EIS-qualifying when I've invested.
- Energy Generation(4): two tidal energy companies, and one generating energy from rivers without the need for weirs/dams. And one supplying information from satellites to help manage renewable infrastructure.
- Energy Efficiency(2): a company producing devices to capture heat from waste water from showers. And a company producing energy-efficient displays.
- Agriculture(2): two companies using technology to supply information to farmers and help optimise (usually reduce) use of irrigation and chemicals. One using sensors in situ, the other satellites.
- Transport(4): a bicycle maker, a developer of hyperloop train technology, and a company offering finance for commuters' season tickets (the last hit hard by covid but not dead yet). Also Pod Point (charge points for electric vehicles), now progressed from crowdfunded startup to listed company.
- Hygeine(1): a company producing a loo that captures and recycles human waste, and a big improvement on old tech like chemical loos. Primarily for situations where there's no sewage infrastructure.
- Plastics(1): a company recycling waste plastics into an alternative to bitumen for road building.
Hopefully others can contribute further ideas/experience with startups aiming to contribute in one way or another to greening the world?
