Proposing solutions to help decision makers harness the economic opportunities of the ecological transition whilst reducing their environmental footprint.
Since May 2022, the Solar Impulse Foundation has launched various efforts to advance the adoption of climate solutions in cities. Having already identified over 1400 efficient Solutions that are both environmentally and economically beneficial, the next step is to apply the most appropriate ones to a city context, recognizing the outsize importance and decision-making power that they have on the mitigation of climate change. A cornerstone of the Solutions Guide for Cities (below) which is complemented by our Solutions City digital platform to navigate key sections of the Guide in an interactive format.
