Advocacy, entrepreneurship, and activism to make the climate transition work today, for all.
Why I do what I do
I believe the climate transition isn’t just about avoiding disaster; it’s an opportunity to improve our current economy and society.
The shift away from fossil fuels delivers immediate benefits, from creating local jobs to reducing energy poverty, healthier homes, and vibrant communities.
What I’ve done so far
Over the past two decades, I’ve focused on systemic change through three interconnected roles: advocacy, entrepreneurship and activism.

Advocacy — public speaking
As one of Al Gore's first climate ambassadors, I have delivered hundreds of talks across Europe, highlighting the benefits of a fossil-free economy. I also contribute to the dialogue through media appearances, opinion pieces, and climate, sustainability, and systemic change articles.

Activism — Klimaatzaak
I initiated and lead Belgium’s Klimaatzaak, the world’s largest climate lawsuit. Mobilizing 70,000 citizens, we achieved a court-mandated 55% emissions reduction target by 2030, setting a legal precedent across Europe. Watch my TEDx talk on ‘Beyond activism — law as a climate tool’.

Advisory — Helios Foundation
As part of a three-person advisory board, I’m helping guide the Helios Foundation in its mission to decarbonize Belgium’s economy. Helios strategically funds innovative solutions and bridges financing gaps by fostering collaboration between academia, industry, and policymakers. Its twin focus on mental health and carbon neutrality reflects the interconnected challenges of creating a sustainable future.
Up next
A year to pause, reflect, and imagine what’s next.
2025 is a deliberate pause—a year to reflect, recharge, and think deeply about the future. After more than two decades of advocacy, entrepreneurship, and activism, I'm taking this time to reconnect with my passions and consider where I can make the greatest contribution.
This year is about:
Learning: exploring new ideas, reading and connecting widely, and diving into the complexities of systemic change.
Recalibration: identifying where my skills and experience can best address pressing challenges.
Enjoyment: embracing life through music, culture, kitesurfing, running, snowboarding, biking, travel, and time with loved ones.
It's not just a break—it's a step back to prepare for whatever comes next.
