A new paper co-authored by DSI affiliated faculty member James Rising, assistant professor in UD’s School of Marine Science and Policy, looks at a report from the United Nations Intergovernmental Panel on Climate Change (IPCC) that showed global greenhouse gas emissions can be reduced by at least half in 2030 at a cost of less than $100 per ton of CO2 equivalent. This study, however, points out that these estimates do not consider some hidden, underlying frictions that might prevent people from simply adopting a newer, greener technology to replace an older, more familiar one.
