The implications of scope and boundary choice on the establishment and success of metropolitan greenhouse gas reduction targets in the United States
In recent years, cities across the United States have devoted considerable attention and resources to developing greenhouse gas (GHG) inventories and climate action plans (CAPs). Using integrated metropolitan-level GHG estimates from publicly available national datasets, we explore the implications of inventory scope and boundary choices for 41 metropolitan areas across the United States. We quantify emissions from ‘under-reported’ activities (i.…
Expert assessments on the future of direct current in buildings
Increasing adoption of distributed generation, improving power electronics, and growing electronic loads in buildings have led researchers to propose increased use of direct current (DC) power distribution systems in buildings. As these systems have proven safe and reliable in other applications, they are now being considered for more widespread use in commercial and residential buildings. But nontechnical obstacles remain that have not been addr…
An integrated approach for estimating greenhouse gas emissions from 100 U.S. metropolitan areas
Cities have become key players in climate change mitigation policy. To develop their climate policies, cities need good assessments of their current and future emissions. We use publically available national datasets to develop an integrated approach for estimating GHG emissions at the metropolitan level over time, between multiple locations, and across sectors. We estimate consistent production-based GHG emissions for the 100 most populated metr…
Effect of regional grid mix, driving patterns and climate on the comparative carbon footprint of gasoline and plug-in electric vehicles in the United States
We compare life cycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) across US counties by accounting for regional differences due to marginal grid mix, ambient temperature, patterns of vehicle miles traveled (VMT), and driving conditions (city versus highway). We find that PEVs can have larger or smaller carbon footprints than gasoline vehicles, depending on these regional factors a…
Life cycle greenhouse gas emissions of Marcellus shale gas
This study estimates the life cycle greenhouse gas (GHG) emissions from the production of Marcellus shale natural gas and compares its emissions with national average US natural gas emissions produced in the year 2008, prior to any significant Marcellus shale development. We estimate that the development and completion of a typical Marcellus shale well results in roughly 5500 t of carbon dioxide equivalent emissions or about 1.8 g CO2e/MJ of gas …
Preparing US community greenhouse gas inventories for climate action plans
This study illustrates how alternative and supplemental community-level greenhouse gas (GHG) inventory techniques could improve climate action planning. Eighteen US community GHG inventories are reviewed for current practice. Inventory techniques could be improved by disaggregating the sectors reported, reporting inventory uncertainty and variability, and aligning inventories with local organizations that could facilitate emissions reductions. Th…
Impact of Power Generation Mix on Life Cycle Assessment and Carbon Footprint Greenhouse Gas Results
The mix of electricity consumed in any stage in the life cycle of a product, process, or industrial sector has a significant effect on the associated inventory of emissions and environmental impacts because of large differences in the power generation method used. Fossil‐fuel‐fired or nuclear‐centralized steam generators; large‐scale and small‐scale hydroelectric power; and renewable options, such as geothermal, wind, and solar power, each have a…
Reducing environmental burdens of solid-state lighting through end-of-life design
With 20% of US electricity used for lighting, energy efficient solid-state lighting technology could have significant benefits. While energy efficiency in use is important, the life cycle cost, energy and environmental impacts of light-emitting diode (LED) solid-state lighting could be reduced by reusing, remanufacturing or recycling components of the end products. Design decisions at this time for the nascent technology can reduce material and m…
The Economic and Environmental Implications of Centralized Stock Keeping
Recent changes to the management of inventory and warehousing methods have created significant changes in business processes. These changes have produced economic savings to firms from reduced handling of supplies. The system‐wide impacts of this shift in methods on overall cost and the environment are still unclear, however. Reductions in inventories can provide significant environmental savings. In this article, we analyze the changes in invent…

Peer Reviewed: Economic Input–Output Models for Environmental Life-Cycle Assessment
Process and product models are commonly used for performing life-cycle assessments (LCAs) of the environmental impacts of materials and products through different stages of fabrication, use, and end-of-life options. In this article, we show that these models can be represented as process flow diagrams or as matrices of process interactions. In either representation, the inventory of environmental emissions and resources used is comparable, provid…
Reuse of Electric Motors in Consumer Products: Design and Analysis of an Electronic Data Log
Product takeback calls for sound strategies of product recovery management One such strategy‐is the reuse of the components of a product. There are consumer products such as power tools whose most expensive component, the electric motor; offers potential for reuse. Empirical evidence reveals that the lifetime of a motor often exceeds the life‐time of the product using it. This article focuses on the reuse of electric motors. For this purpose, a n…
Clean Recycling of Lead‐Acid Batteries for Electric Vehicles: A Reply to Socolow and Thomas
This article is stimulated by the analysis of Socolow and Thomas in the first issue of this journal. Our work showed that a lead‐acid battery‐powered electric vehicle (Ev) would result in more lead being discharged into the environment than a comparable car burning leaded gasoline. Five hundred thousand EVs would lead to a 20% increase in lead use in the United States, and presumably a comparable 20% increase in lead discharges. The Socolow‐Thoma…
