The challenge is huge, but we are Undaunted
Time is running out to halt the climate crisis, and our window of opportunity to create a greener, more sustainable future is closing fast. We need practical solutions on a scale never achieved before. Innovation is crucial.

Unimaginable Unprecedented Undaunted
Our alumni will have real-world impact
We build a bridge from the experimentation and discovery stage of climate technology, nurturing innovation until it is ready to be scaled up. Our activities – including our flagship Greenhouse climate accelerator programme – stimulate the commercial sector to follow and develop a wider ecosystem where green solutions can flourish. We are creating the blueprint for a successful climate innovation ecosystem.
