Søren E. Lütken, PhD and senior economist at UNEP DTU, combines an MBA background and a PhD in climate finance with experience from ten years of service in the Danish Ministry of Foreign Affairs, of which two years posted in India and three in China to implement the Danish bilateral climate change assistance. Before these postings, he brought together the team that established EBRDs first ESCO in Eastern Europe in 1997 and since then has been working on climate change related project development and financing with a prime focus on energy efficiency and renewable energy sources. Since his posting in Beijing, he worked another two years in private business in China, developing a concept for ESCOs in the iron and steel sector before taking up his current position with UNEP DTU and later its Copenhagen Centre on Energy Efficiency. Here, he coined the idea of setting up the Global ESCO Network as a specific initiative to place ESCOs centrally to achieving the climate change objectives of the Paris Agreement. He is the author of several working papers on finance issues as well two internationally published books: ‘Corporate Strategies and the CDM – developing country financing for developed country commitments?’ (2008) and 'Financial Engineering of climate investment in Developing Countries' (2014).
