The need for easily understandable information regarding sustainability issues is constantly increasing. By creating the ‘Sustainability Unfolded’ platform, Metsä Board, part of Metsä Group, aims to provide a consumer-oriented and fresh way to open up and address sustainability topics, especially in the context of packaging sustainability. The targets are clear: increase understanding, challenge myths, and help make the right everyday choices. When talking about sustainability, themes like deforestation, climate change, recycling and greenwashing are crucial topics that deserve attention. In the era of information overload, corporations have to find ways to democratise sustainability information and make it more accessible and understandable. Metsä Board decided to tackle this in a new way. “The way ‘Sustainability Unfolded’ talks about these complex issues is somewhat unconventional for the industrial B2B-sector. The goal is to stimulate and engage the reader, and encourage everyone to look at the topics from a wider viewpoint. We built an editorial platform to make the subject matter more engaging to consume, with intriguing headlines and content that people will want to explore further,” states Marjo Halonen, VP Communications at Metsä Board.
