This year is YEE's 30th birthday and we are celebrating with the campaign 30 years of volunteering for environment. Workshops are taking place across six countries to distribute the campaign's materials and promote volunteering for the environment.

On 7 September 2013 the YEE office traveled to Castle Lukov in the Czech Republic for a special festival hosted by Hnutí Brontosaurus. The festival brought young people together to volunteer on maintenance projects around the castle and in the local environment. There was also a workshop space for volunteers to share music, food and skills.

YEE used this opportunity to promote new ways to volunteer for the environment. Upcycling workshops were offered to inspire young people to rethink the concept of 'waste'. The team spoke with festival goers about how they can volunteer for the environment through YEE and invited people to take the free campaign materials. Joining the network allows members to participate in educational youth exchanges, trainings and campaigns that work towards a more sustainable world.
