The Earth System Governance Project (or ESG Project in short) is a research network that builds on the work from about a dozen research centers and hundreds of researchers studying earth system governance. It is a long-term, interdisciplinary social science research alliance. Its origins are an international program called the International Human Dimensions Programme on Global Environmental Change. The ESG Project started in January 2009. Over time, it has evolved into a broader research alliance that builds on an international network of research centers, lead faculty and research fellows. It is now the largest social science research network in the area of governance and global environmental change.
Utrecht University in the Netherlands has hosted the secretariat, called International Project Office, from 2019 to 2024. Previously the secretariat was at United Nations University in Bonn, Germany (from 2009 to 2012) and at Lund University, Sweden (from 2012 to 2018).
