The Environmental Data and Governance Initiative (EDGI) is an international network of academics and nonprofits addressing potential threats to federal environmental and energy policy, and to the scientific research infrastructure built to investigate, inform, and enforce them. EDGI documents, contextualizes, and analyzes current changes to environmental data and governance practices through multidisciplinary and cross-professional collaborative work. EDGI fosters the stewardship and expansion of public knowledge through building participatory civic technologies and infrastructures to make data and decision-making more accessible. EDGI creates new communities of practice to enable government and industry accountability.
