Prof. Toohey has been involved with issues of science policy dating back to his work on ozone-depleting substances in the 1980s and 1990s. He has been a co-author of multiple assessments of stratospheric ozone and impacts of aircraft on air chemistry and climate. In 2011-2012 he served as a Jefferson Science Fellow at the U.S. Department of State in the Bureau of East Asian and Pacific Affairs, working on issues related to energy and green growth for APEC. He organized a high-level meeting on Open Governance and Economic Growth, chaired by the Secretary of State, served as a delegate for the United States at the 10th APEC Energy Ministerial Meeting, and organized an APEC Workshop in Singapore on the use of observations to address resilience and disaster response. Following that year of service, from 2013 to 2015 he helped a group of international scientists develop a sucessful proposal for hosting a hub of the Future Earth Secretariat in the United States and for linking educators and researchers in Colorado and in the United States working in the fields of sustainability and global development. In 2019 he co-authored an article calling for awareness of the role of increased emissions of rockets on stratospheric circulation.
