Pär Holmgren, Sweden

His commitment to his cause has seen him taking part in public debates, appearing on children's television and using music to attract a younger audience.
Holmgren's lectures and his website are used to influence both public opinion and decision-makers.
His 'Climate Change and the Baltic Sea' lecture and the pamphlet 'Climate Change and the Baltic Sea – What Can I Do?' also attracted attention during 'Baltic Sea Day', which was organised by the nominator.
