This paper presents estimates of exhaust emissions from a container vessel during its voyages by using current best-practice inventory methodology. Emission estimates are performed for both criteria air pollutants and greenhouse gases. Two approaches, power-based and fuel-based, are applied for emission calculations, where the former involves multiplying power-based emission factors by engine power...
This paper summarizes a modeling framework that characterizes the key underlying technologies and processes that contribute to the supply chain energy use and greenhouse gas (GHG) emissions of a variety of goods and services purchased by U.S. consumers. The framework couples an input-output supply chain modeling approach with ldquobottom-uprdquo fuel end use models for individual IO sectors. This...
The Millenium Ecosystem Assessment (MEA) has highlighted the fast depletion of ecosystem services over the past 50 years and has identified their crucial role in human well-being. This emphasizes the need of accounting for ecosystem goods and services in life cycle of products and processes. Despite the availability of numerous Life Cycle Assessment (LCA) techniques, most methods only account for...
The sustainability impacts of route guidance system under the cooperative vehicle infrastructure environment were examined under the various market penetration rates of equipped vehicles at 0%, 5%, 25%, 50%, 75%, and 100%. To evaluate the impacts, this study used an advanced simulation test-bed enabling car-to-car and car-to-infrastructure communications based on a microscopic traffic simulation model,...
