Innovation Zero - Climate & Cleantech Congress

Innovation Zero is a two-day climate and clean tech congress taking place in London on 24 and 25 May 2023

Innovation Zero will accelerate partnerships, deal-making and collaborations between those developing and producing low carbon solutions and those who need to deploy or want to fund them. An annual meeting place for connections, announcements and trade that accelerates the transition to a low carbon economy.

Some 200 providers exhibiting their low carbon solutions and 200+ speakers sharing their expertise to over 7,000 attendees will fill the show floor at the historic Olympia, London venue.

This key event will accelerate the commercialisation of solutions for the essential and urgent decarbonisation of our economy and society, bringing together impactful international investors with the unicorns of the near future. It will connect firms creating forward-thinking low carbon solutions with the expertise, funding and customers to enable rapid growth.

The event will feature presentations, announcements, briefings and case studies from policymakers, finance and business, an opportunity to showcase and see the latest green tech innovations across a range of key sectors including energy, transport, built environment and many more.



We are motivated by the creativity and ingenuity of private enterprise and the free market solutions to develop the products and services that will deliver decarbonisation for our society and economy.

The senior team at Clean Tech Events contributes around 60 years of organising world class events including Mobile World Congress and BETT. Our approach to organising events is based on delivering value, relevance and opportunity for our visitors, speakers, exhibitors, partners and sponsors.

We will take every opportunity to use low carbon solutions to build the event and will improve upon this each year. We have partnered with Olympia London, which is the most sustainable venue in the UK. Ultimately, the mission of the event is to connect people to do good business faster.

Innovation in technology is essential to meet the critical targets needed to solve the climate crisis and preserve a liveable planet for future generations. It’s the defining challenge of our lifetimes and with it the greatest business opportunity. We exist to champion the opportunity and encourage all businesses who are investing and researching low and no carbon solutions to now consider themselves clean tech companies.
