Book Description
Motivated by the emerging importance of sustainability in transportation infrastructure, this study aims at developing a Life Cycle Assessment (LCA) tool to quantify the energy and environmental impacts of pavements. The general LCA framework is incorporated into a highly customizable Excel-based software tool that can be used to facilitate environmental assessment of pavements at the project-level. The impact assessment focuses on the cumulative energy demand (CED) and greenhouse gas (GHG) emission in the material, construction, and maintenance phases of pavement life-cycle. LCA results are highly dependent on the quality and appropriateness of data in the life cycle inventory. Therefore, different inventory database from major pertinent studies were reviewed and summarized. To implement the LCA framework, case studies regarding runway pavement rehabilitation/reconstruction at the John F. Kennedy (JFK) airport and new runway pavement designs conducted using the Federal Aviation Administration (FAA) pavement design methodology were conducted. Life-cycle inventory data were compiled from literature and field surveys from contractors. The data variations in the material-related energy and emission rates were considered for sensitivity analysis. Both direct energy consumption and GHG emission and their corresponding upstream components related to process fuels were considered in the impact assessment. The results indicate that the expected pavement service life and maintenance treatments significantly affect the comparison between hot-mix asphalt (HMA) and Portland cement concrete (PCC) pavements. The consideration of energy and emissions associated with the production of process fuels and electricity in the upstream process cannot be neglected in the LCA. The analysis findings suggest that there are no general conclusions on pavement type selection for sustainability and the project-level analysis need be conducted for selecting the most appropriate design alternatives.

Book Description
Environmental Life Cycle Assessment (ELCA) that was developed about three decades ago demands a broadening of its scope to include lifecycle costing and social aspects of life cycle assessment as well, drawing on the three-pillar or ‘triple bottom line’ model of sustainability, which is the result of the development of the Life Cycle Sustainability Assessment (LCSA). LCSA refers to the evaluation of all environmental, social and economic negative impacts and benefits in decision-making processes towards more sustainable products throughout their life cycle. Combination of environmental and social life cycle assessments along with life cycle costing leads to life cycle sustainability assessment (LCSA). This book highlights various aspects of life cycle sustainability assessment (LCSA).

Book Description
An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.

Book Description
How can we design more sustainable industrial and urban systems that reduce environmental impacts while supporting a high quality of life for everyone? What progress has been made towards reducing resource use and waste, and what are the prospects for more resilient, material-efficient economies? What are the environmental and social impacts of global supply chains and how can they be measured and improved? Such questions are at the heart of the emerging discipline of industrial ecology, covered in Taking Stock of Industrial Ecology. Leading authors, researchers and practitioners review how far industrial ecology has developed and current issues and concerns, with illustrations of what the industrial ecology paradigm has achieved in public policy, corporate strategy and industrial practice. It provides an introduction for students coming to industrial ecology and for professionals who wish to understand what industrial ecology can offer, a reference for researchers and practitioners and a source of case studies for teachers.

Book Description
This book provides insight into the Life Cycle Management (LCM) concept and the progress in its implementation. LCM is a management concept applied in industrial and service sectors to improve products and services, while enhancing the overall sustainability performance of business and its value chains. In this regard, LCM is an opportunity to differentiate through sustainability performance on the market place, working with all departments of a company such as research and development, procurement and marketing, and to enhance the collaboration with stakeholders along a company’s value chain. LCM is used beyond short-term business success and aims at long-term achievements by minimizing environmental and socio-economic burden, while maximizing economic and social value.
