Small change. Big impact.

Choosing a different way to travel once in a while can make a big difference. The places where we live, work, and socialise get cleaner and quieter. Roads can flow more smoothly for those who need to drive. Travelling sustainably can also help people save money, be more active, be more healthy and enjoy the journey itself.

1dayaweek is a photo competition with monthly prizes. It encourages people to leave the car at home a little more often. Because less traffic benefits everyone.

Whether you are looking to save money, be more active, or reduce your environmental impact, join us. And if you share your sustainable journeys, you’re in for the chance to be rewarded with monthly prizes.
