In the face of climate change, we are

Undaunted is a hub for the UK’s climate innovation community, creating new routes into green entrepreneurship and supporting the acceleration of startups and SMEs tackling climate change.

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.

Undaunted – a partnership between Imperial College London and the Royal Institution – is fostering a thriving innovation ecosystem that aims to make London and the UK a great place to start and scale intelligent, sustainable solutions to the climate challenge at pace.

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.
