Analysis Of The Benefits Of Green Streets, Christopher E. Ferrell, John M. Eells, Richard W. Lee, Reyhane Hosseinzade

Mineta Transportation Institute

Green streets offer many potential benefits that include improving water quality, absorbing carbon (sequestration), and reducing urban heat island effects. This report summarizes: (1) the research team’s analysis of 14 tools calculating green streets benefits; and (2) the results of applying the most promising calculators to a select group of green streets case studies. The researchers are affiliated with the Mineta Transportation Institute, which serves the California Department of Transportation (“Caltrans”). The report presents the results of the case study analyses, with an emphasis on carbon sequestration benefits and improvements to pedestrian levels of service (PLOS).

Research Gaps In Environmental Life Cycle Assessments Of Lithium Ion Batteries For Grid-Scale Stationary Energy Storage Systems: End-Of-Life Options And Other Issues, Matthew Pellow, Hanjiro Ambrose, Dustin Mulvaney, Rick Betita, Stephanie Shaw

Faculty Publications, Environmental Studies

Although deployments of grid-scale stationary lithium ion battery energy storage systems are accelerating, the environmental impacts of this new infrastructure class are not well studied. To date, a small literature of environmental life cycle assessments (LCAs) and related studies has examined associated environmental impacts, but they rely on a variety of methods and system boundaries rather than a consistent approach. The large LCA literature of transportation applications of LIB contains selected life-cycle inventory data relevant for stationary ESSs, but does not incorporate characteristics unique to stationary systems, such as balance of system materials; operational profiles; and perhaps even different end-of-life …
