How will disruption and transformation impact you? Build powerful new alliances at Cleantech Forum Europe in Luxembourg on 18-20 May.

Since 2002, we’ve brought together global investors, innovators, corporates and change makers looking for answers to the biggest question: who will lead the transformation we’re all waiting for?

We’ll let our community tell you what makes Cleantech Forum Europe invaluable.

Reasons to attend Cleantech Forum Europe Sandra TrittenCleantech Forum Europe is a conference where you exchange in an interactive way on the latest topics with all different kinds of stakeholders relevant to our ecological and environmental future. It is a unique opportunity you can only get there.”

-Sandra Trittin, Co-Founder and Head of Business Development & Marketing, tiko Energy Solutions



“For me, the Cleantech Forum remains a unique opportunity to meet with the most significant and active investors in clean energy and environmental technologies in Europe, partake in conversations that inform new investment directions and create opportunities to work with peers in supporting new companies together. the Forum’s uniqueness resides in its ability to bring together the whole industry for a couple of days and create the opportunities for co-investment in portfolio companies”                                                             

                                                        -Julien Mialaret, Operating Partner, Idinvest Partners

What to Expect

A wide range of sessions means you can choose the topics and formats that interest you most. Pursue your area or expertise or widen your horizons. Our agenda will cover all six of our industrial sectors.


Our rapidly evolving agenda for the Luxembourg Forum is built around three tracks:

Financing the Transition – how will we balance innovation and investment?

The number of large corporates pledging to pursue carbon neutrality is multiplying. This will favour early-stage companies. Will they lead larger organizations on their journey to carbon neutrality?

Circularity – can we stop the make, use and dispose model?

By breaking away from the consumption of limited resources, circularity across all sectors will develop new industry openings. What is the scope and scale of the opportunities?

Digitization – is data the key to a cleaner future?

Edge devices, artificial intelligence and data platforms provide new tools to collect and analyze data for informed investment and service improvements. But does data have limits and where are its most valuable applications?
