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.
We envision a world with a healthy, global climate innovation ecosystem, where diverse innovators leading businesses of all sizes can deliver significant emissions reductions and climate resilience sustainably and at scale.
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.
