Our mission is to bring sustainable innovation to the people most at risk from climate impacts.

The best way to predict the future is to invent it. - Theodore Hook

Without access to reliable power and clean water, communities cannot have security, health, and autonomy. Clean, sustainable resources are necessary for the billion people who live in poverty to build a path to prosperity.

The Last Kilometer works to bridge the gap between innovation and the adoption of sustainable technology.  Our programs show how clean energy, water, food, and shelter technologies can be used by organizations to grow sustainably and become more resilient.

Introducing new technology to the world beyond the grid comes with unique risks and challenges. As a non-profit, The Last Kilometer helps pilot and study the impact of new climate solutions and help ready them for deployment at a scale needed to address our global resource challenges.
