Scott Matthews is a professor in the Departments of Civil and Environmental Engineering, and Engineering and Public Policy.

His work intends to facilitate infrastructure and policy decision making under uncertainty via large and innovative datasets, computation, and visualization methods. His primary current interests are in the areas of transportation and society. He has previously contributed to the development of research and education tools for environmental and energy life-cycle assessment of products and processes (such as the EIO-LCA model), estimating and tracking environmental effects across global supply chains (such as carbon footprinting), and the sustainability of infrastructure systems.

At Carnegie Mellon, he has taught graduate and undergraduate courses in the Departments of Economics, Civil and Environmental Engineering, Engineering and Public Policy, and Computer Science. Matthews has served as chair of the Committee on Sustainable Systems and Technology with the Institute of Electrical and Electronic Engineers and on the Executive Committee for the American Center for Life Cycle Assessment. He participated in the National Research Council (NRC) study on the Hidden Costs of Energy and is a member of the NRC Board on Environmental Studies and Toxicology.

Cutting vehicle emissions and inspections via IoT

A new system using remote data transfers and machine learning could cut vehicle emissions, lower testing costs, and drastically reduce the need for in-person emissions testing.


Matthews’ research adds to conversation on green online shopping

Amazon is facing increasing pressure to make their online shopping more environmentally friendly. This goal should be possible, since a study by CEE/EPP’s H. Scott Matthews found that delivering an online purchase usually has about half the carbon impact of traditional shopping. However, the advantage disappears when customers choose faster shipping, one of the main appeals of Amazon’s Prime program.
