Norwegian energy company Hafslund, a major provider of renewable energy, wished to further their green credentials while educating a new generation on issues of sustainability. Two of their main communication challenges are that in general, people know little about the company except that they are selling power - and there are few positive emotional associations related to the brand Hafslund. Important parts of building their reputation has therefore been to build knowledge of Hafslund’s commitment to the environment and renewable energy and show more of their commitment within CSR. Some major projects were defined. The most ambitious was a major climate festival for children, held on World Environment Day in June 2010. The goal was to create favorable conditions for environmental engagement, and inspire children to find new solutions. It was supported with a blog initiative, a creative school project and a unique media partnership. Over 35,000 people attended the event, and it was possibly one of the world's largest events on World Environment Day. 37 percent of those with knowledge of Hafslund's association with the event now have a more positive attitude towards them. The project was such a success the the festival will be organized again in 2011.

The reporters were prepared for their task, and trained by the environment foundation Bellona and a copywriter.

The launch of the festival, school competition and Kraftrevyen was held at a primary school. Attending the launch was the Mayor, Hafslund, relevant artists and media. Some 40 stories were published on Kraftrevyen, leading up to the festival. DittOslo.no published many of the articles from Kraftrevyen.Two reporters were hired by Norway's largest weekly to do interviews. Others were interviewed themselves, and one provided regular reports to Norway's largest radio station. During the festival the children were roving reporters, interviewing artists about environmental issues live on stage and producing stories which were broadcasted around the festival area.The winning entries in the competition was exhibited and awarded prizes to allow them to implement their energy-saving plans. Oslo's Mayor also was a juror in the competition.

Polls from TNS Gallup showed nearly 40 percent of visitors to the festival left with a more positive impression of the company. Polls also showed a strong word of mouth effect for the event. 56 percent of Oslo citizens (in addition to those who visited the festival) knew about the event. Nearly 100 percent of the visitors said they were positive to the festival and its message, and all visitors said they knew Hafslund was the event organizer. The average score given by visitors was five out of six, while one in four visitors gave the festival a top score of six. There were some 120 stories in the media from the launch until the end of the festival. The young "environment reporters'" stories come in addition to this. The project was such a success, the festival will be organized again in 2011.
