1000+ profitable solutions to protect the environment

To address environmental challenges without compromising economic growth, Bertrand Piccard and the Solar Impulse Foundation have identified 1000+ clean and profitable solutions, and are now committed to going even further. By offering political and economic decision-makers a Guide to Solutions that can be implemented on a large scale, the Foundation will help them establish a roadmap for the adoption of much more ambitious energy and environmental programs and thus achieve their carbon neutrality objectives.

Advocacy Switzerland

When the Climate Changes, so Must the Laws.

The success of the green transition depends less on the development of new technologies, but rather on the creation of favourable conditions to increase the adoption of current solutions and benefit from their widespread implementation.

Prêt à Voter Switzerland

The Solar Impulse Foundation has launched Prêt à Voter Switzerland, 25+ legislative recommendations which take clean technologies as a starting point in guiding the modernisation of the Swiss legal and regulatory framework.

Going Further

This is part of a wider initiative to change laws to accelerate the speed of the ecological transition. To this end, we are collaborating with nine other organizations in Switzerland who advocate for greater cleantech adoption. This summer members of this collective will publish a series of articles that will serve as a practical guide to advancing this cause,  from working with innovative companies, campaigning and mobilising key actors, to identifying the business case for certain laws and navigating the political system. Each article focuses on a specific topic and is contributed by a specialist organisation or actor in that particular field.
