Do you invest in clean and profitable technologies?


Why investors join us

For us, as investors, the Solar Impulse Label was a very positive sign during the due diligence, as it validated the technological part of the company, while we were more focused on the financial side,

It’s very likely that your portfolio is full of solutions that can protect the environment in a profitable way. What better way to offer added visibility and opportunities to these companies than to have them labelled as efficient solutions? You can encourage your portfolio companies to apply for the Solar Impulse label, but if you are keen to setup a more extensive collaboration to incoporate your investments into the 1000 solutions portfolio, don’t hesitate to reach out to Willem van Hasselt

The European Investment Bank is the EU’s Climate Bank and financing new technologies and innovative firms that help to fight climate change is at the very heart of what we do. With the Solar Impulse Foundation, Mr. Piccard fosters cutting-edge technologies and solutions for a greener society. That is why we are particularly happy to support this endeavour.
