How to protect the environment?

Environmental protection has been a global priority for many years now, but progress has been slower than it needs to be. That’s in part because environmental solutions have frequently only been considered from an ecological point of view. But to be implemented at the rate and scale required, solutions to environmental degradation and pollution must be profitable.

The Solar Impulse Foundation is committed to selecting 1000 solutions that are not only designed to protect and save the environment, but also afford opportunities for clean economic growth. Today, there exist ways to solve environmental issues that make sense financially and ecologically. Our objective is to bring them to decision-makers, businesses and users across the world.
