About us

Every trip, leisure or business, can be a driver of positive change. Together with our partners, we co-create new ways of travelling and getting around, accelerating the shift towards responsible mobility and regenerative tourism.

Our story

Greentripper

Greentripper was founded in December 2018 with a mission to preserve our ability to travel while taking action on the carbon footprint of travel. Since then, we have raised awareness among thousands of travellers who have calculated and compared their impact and contributed to climate projects. Together, we have already funded over 100.000 tonnes of CO₂e : emissions avoided, captured, or reduced through the projects we support.

We are active members of several tourism networks, including UPAV, VVR, ATR, ATD, and ETOA. We have signed the Glasgow Declaration and participate in European initiatives for sustainable tourism such as ATR-E, Together for EU Tourism, Future of Tourism, and Travel4Impact.

Based in Brussels and active worldwide, we collaborate with tourism professionals to measure and reduce the environmental impact of their trips, contribute for unavoidable emissions, and communicate their impact more transparently.

What we do

Empowering climate action

At Greentripper, we help travellers and businesses understand their impact and give something back to nature through concrete actions.

We provide digital tools and consultancy to calculate your carbon footprint, compare it with more sustainable alternatives, and reduce it as much as possible. For emissions that cannot be avoided, you can support climate projects. We also help you share your efforts and communicate about your impact in a transparent way.

When we all take responsibility for our emissions, we can collectively tackle the climate crisis. Climate change is a global challenge that demands global collaboration. That’s why we continuously co-create solutions with our clients and partners while spreading awareness and inspiring action.

Our community

The industry of dreams & memories

The travel industry brings people together, creates opportunities for personal and cultural growth, supports economies around the world, and allows us to experience the beauty of our planet.

To keep exploring the world, we need to protect these treasures, take our footprint seriously, and act.

Our values

Inspire to change

We encourage travellers to rethink the way they travel, choosing journeys that not only minimise their negative impact but also create positive change, showing that every action - no matter how small - supports the transition.

Dream beyond

We believe in driving change through passion and showing real solutions that inspire a sustainable movement. It’s about rethinking the way we travel: shifting from “Why bother travelling sustainably?” to “What if we travelled differently?”

Community-driven innovation

We see our community as true partners, bringing their insights and needs into everything we build. Every travel company has its own reality. We work side by side to find the right solution for each partner.

Purpose in action

Protecting our planet goes hand in hand with caring for its people. We work with travellers, businesses, and organizations to co-create solutions that benefit everyone.
