This study demonstrates how three Finnish companies in different business fields construct their relationships with environmental NGOs in their sustainability reports concerning during the studied timeframe, years 2007-2011. The study identifies five different types of relationships constructed in the reports between ENGOs and the corporation: monetary based, management system based, collaborative, dialogue based and conflicting relationships. The study shows that the descriptions of relationships are very neutral, and both the intensive environmental management alliances and conflicting relationships are mainly missing in the reports.
