RSI Logo

The Resnick Sustainability Institute (RSI) advances global sustainability through transformational science, engineering, and education. We prioritize research across campus that addresses challenges and opportunities associated with climate change and the stewardship of natural resources. The fundamental insights gained are directed towards implementation and scale-up for real-world impact.


RSI research is broadly focused on four interconnected initiatives, where Caltech researchers are poised to provide uniquely impactful science and technology solutions.
