Christian Berg was fortunate to have worked across sustainability topics in industry and academia, for more than 20 years. He has led corporate teams and consultancies in sustainability research and design and was in charge of the Sustainable Economic Activity and Growth taskforce for German Chancellor Angela Merkel.

As Chief Sustainability Architect in the management consultancy of SAP, he was responsible for the topic of sustainability for many years. He has been Visiting Professor for Corporate Sustainability at Saarland University since 2010 and Honorary Professor of Sustainability and Global Change at Clausthal University of Technology since 2008. Christian Berg has advised the former German Chancellor on the issues of sustainable business, among others. Each experience has contributed to how he conceive of sustainability and the path forward for modern society.

Christian has recently published a book about sustainability transitions: Sustainable Action: Overcoming the Barriers. The book, published by Routledge, takes a transdisciplinary, systems-led approach to understanding the barriers we face in moving towards a sustainable future; barriers to physical reality, the human condition and social reality, and within economy, politics, law and technology. For each of these barriers, the book offers solutions as ‘action principles’; principles that provide actionable solutions for every level from individuals to corporations to governments and supra-national organizations. This is, to his knowledge, the first integrated, comprehensive account of sustainability barriers across borders and disciplines.
