This study analyzed the sustainability and environmental impact of indoor recirculating aquaculture systems (RAS) used for raising shrimp in the U.S. A life cycle analysis (LCA) was performed to evalu...

 Temporal and regional variability in the technological characteristics of primary aluminum smelters affect life cycle greenhouse gas (GHG) emissions embodied not only in the production but...

Aurora Organic Dairy (AOD) is the largest provider of private-label organic milk and butter in the U.S. managing over 12000 milking cows and processing over 84 million liters (22 million gallons) of m...

Personal transportation accounts for 17 percent of total greenhouse gas emissions in the United States and must be a major component of any climate change mitigation plan. While technological advancem...

Gasoline and diesel automobiles dominate current personal transportation in the United States. The automotive industry has been developing PHEVs (plug in hybrid electric vehicles) in response to incre...

Pavement preservation (maintenance and rehabilitation) requires large resource investments and generates significant environmental impacts. A project-level pavement asset management system (PAMS) i...

Introduction: Conventionally CO2 abated by generating photovoltaic electricity has been evaluated using average grid fuel mix profiles at various scales. However at low capacity PV installations i...

The electrical consumption from central air conditioners currently accounts for about 14% of residential electrical use in the United States. Utilizing more efficient air conditioning units is one str...

In this paper we consider life cycle emissions paybacks and costs associated with lightweighting (LW) automobiles. Both aluminum and high strength steel (HSS) are considered with LW ranging from 6%...

This paper develops new methods to model and control the aggregated power demand from a population of thermostatically controlled loads, with the goal of delivering services such as regulation and loa...

Organic agriculture has sustained consistent growth in the U.S. over the past decade, but very little systemic environmental impact benchmarking has been performed.  This study is the first life ...

Primary aluminum ingot is a globally traded commodity, and large regional differences in technology and electricity fuel mixes exist among the industry's smelters. A life cycle assessment model is dev...

Vehicle capability is one of the factors that constrain the set of transportation options available for personal transportation. The capacity for carrying passengers and cargo is of particular interes...

A country-level stock and flow model for cement, an important construction material, was developed based on a material flow analysis framework. Using this model, the contemporary cement cycle of the U...

This study uses life-cycle assessment (LCA) methodology to quantify life-cycle energy use, greenhouse gas emissions, solid waste generation and water use for delivering drinking water to consumer h...
