Peter Coates analyzes the UK universities’ “impact” criterion, which emphasizes measurable contributions to public policy and the economy, and uses it to highlight the distinctive relevance of environmental history. He shows how the field has gained traction in the UK through high-profile conferences and funding initiatives that connect the humanities with ecological sciences. Coates also notes that nonacademic partners value environmental historians’ ability to provide cultural perspectives on ecological change and to link local issues with broader historical and geographical contexts.
