CleanTech Challenge 2025

Rewarding the next student led innovative clean technology ideas

Applications for the 2025 CleanTech Challenge are now OPEN

 
The competition

The CleanTech Challenge is a global business plan competition for students with innovative clean technology ideas. Hosted by London Business School in conjunction with University College London, the challenge is powered by our sponsor, Gore Street Capital. Since 2011, the CTC has been run successfully for the past 13 years and brings in applications from students in more than 25 countries annually. 

The objective

Great Cleantech technologies emerging from research often flounder through lack of good commercial input early on. Meanwhile, management schools have many entrepreneurial students who are worried about the environment but who lack impactful ideas to work on. To bridge this gap, the interdisciplinary competition was created, to promote CleanTech thoughts in today’s educational institutions.

Who can enter

The Challenge is open to all current university students (undergraduate, postgraduate and phd) enrolled in a degree programme at a recognised Higher Education Institution anywhere in the world as of 1 January 2025.
