Seeberg, Fredrik & Zetterlund, Philip, 2017, Green energy, can it ever be wrong? - A qualitative study about how electricity supply companies uses CSR communications. (Grön el är aldrig fel? - En kvalitativ studie om hur elhandelsbolag i Sverige använder sig av CSR-Kommunikation) Environmental climate changes are a hot topic in the world today. Producing and delivering energy makes a big impact to that change and energy corporations are therefore inclined to use positive results and methods to claim a “Green” image. One common method to prove a corporation’s effort is Corporate Social Responsibility (CSR). This study compares the usage of CSR as a communication tool by two Swedish energy corporations of very different sizes, Mälarkraft, a local corporation with about 150,000 customers, and E.ON Sverige, Sweden’s second largest energy supplier with over a million customers. Our study shows, that despite the difference in sizes, that both corporations uses CSR to achieve the same notion, a more favourable reputation. Their means to achieve this however, is clearly different. By studying the corporations strategies with interviews and context analysis of internet web pages, we show that the difference in sizes and local connection help differentiate the strategies.
