On 9 and 10 October, it's time again for Impact Day in the beautiful old city of Tallinn in Estonia. If you want to try something different, gain inspiration and discover a new city, this is the perfect opportunity.

Talking about the climate and making a personal contribution is no longer the preserve of a small group of people. In the past, they were called tree huggers or climate fanatics.

Organizer Micha van Hoorn and his team are busy with the final preparations to ensure that everything runs smoothly when the Impact Fair in Utrecht starts. Organizing such an event is quite a roller coaster: a two-day trade fair followed by an open day on the Saturday.
