We make sustainability work for you.

About Act by Choice

We all want to do better we just need it to make sense and be easy to act on.

That’s where Act by Choice comes in.

We turn sustainability complexity into practical actions that work in real life and drive both business results and genuine impact.

We believe change only happens when it feels possible, practical, and rewarding.

Easy. Simple. Meaningful.

Sustainability change makers.

Act by Choice is a team of passionate changemakers dedicated to turning sustainability into an opportunity, not an obstacle. 

We enable organisations and travelers to bridge the gap between good intentions and meaningful action making sustainable choices simple, accessible, and rewarding.

Our founder, Josephine, has spent over 25 years in the travel industry, seeing firsthand how both travelers and businesses want to do better. But there’s a challenge: while the willingness to act is there, the path forward isn’t always clear. Many believe that consumers simply aren’t interested in sustainability.

We see things differently!

The real problem isn’t motivation – it’s complexity. Sustainability needs to be straightforward and actionable.

At Act by Choice, we cut through the noise and turn sustainability into practical, everyday actions that make sense. 


We work with travel and tourism industry organizations to create real impact helping them integrate sustainability in ways that attract customers, enhance experiences, and contribute to a better world.

Our vision

A world where choosing more sustainably is effortless for all.

Our mission

Our mission is to make sustainability the new normal by making it easy to get started, simple to act, and powerful to communicate.
