Book Description
Product life-cycle optimization addresses the reduction ofenvironmental burdens associated with the production, use, andend-of-life stages of a product s life cycle. In this paper, we offer anevaluation of the opportunities related to product life-cycleoptimization in California for two key products: personal computers (PCs)and concrete. For each product, we present the results of an explorativecase study to identify specific opportunities for greenhouse gas (GHG)emissions reductions at each stage of the product life cycle. We thenoffer a discussion of the practical policy options that may exist forrealizing the identified GHG reduction opportunities. The case studiesdemonstrate that there may be significant GHG mitigation options as wellas a number of policy options that could lead to life-cycle GHG emissionsreductions for PCs and concrete in California.

Book Description
Low-carbon design is a sustainable method, which coordinates the carbon footprint, cost and performance of each stage in product lifecycle from the design source to satisfying low-carbon demand. It is also a significant technology to reduce the carbon emission before manufacturing. To effectively and efficiently reduce the carbon emission, a low carbon-oriented design method is studied in product lifecycle.

Book Description
The manufacturing sector is a significant contributor to environmental damage and resource use, which has potential long-term implications if resources are overused and our air, water, and soil are altered irreversibly. To alleviate these impacts, the manufacturing research community has primarily focused on reducing the environmental impacts of specific manufacturing processes and systems within a factory; however there are opportunities for environmental impact reductions that emerge from a supply chain perspective. For example, researchers have recognized that by taking advantage of regional differences when locating facilities there is the opportunity to alleviate global water scarcity and reduce the human health effects of pollution. We add to this body of work by focusing on the opportunity to take advantage of regional variability to reduce supply chain GHG emissions. Through the development of targeted environmental return-on-investment (ROI) metrics and hybrid life-cycle assessment techniques, we enable the minimization of global greenhouse gas emissions through informed supply chain design. Founded on the premise that GHG emissions are a global problem that can benefit from global optimization, we focus on the tradeoffs between transportation emissions and electricity emissions. A three-pronged approach to management and reduction of GHG emissions in manufacturing is presented: (1) metric design for environmental decision-making (2) comprehensive, repeatable, and efficient life-cycle assessment using a hybrid approach (3) optimization of the system to take advantage of regional tradeoffs. This approach is demonstrated through a generic case study of automotive manufacturing and a case study of SolFocus Inc. concentrated solar photovoltaic panels. The case-studies show that 30-40% of GHG emissions in the supply chain are from electricity and transportation and can be reduced by up to 50% through changes in supplier location. Furthermore, regional variability in electricity emissions means that local manufacturing is not always optimal. Finally, the incorporation of ROI metrics for the SolFocus system presented the most rapid path to global reductions in GHG emissions. Installation of solar technology in Australia results in a savings of nearly 20 kg-CO2eq for every kg-CO2eq emitted during production; whereas the savings from installation in Spain, Northern California, or Arizona is 7-8 kg-CO2eq. This dissertation presents the following new contributions to the field (1) a method for global GHG reductions, separate from product re-design, through optimization of supply chain layout based on transportation and electricity GHG emissions tradeoffs; (2) development of effective and targeted ROI environmental metrics to guide decisions that promote the fastest route to reduce environmental impacts in manufacturing; (3) validation of the feasibility of using of iterative financial hybrid LCA to ensure a comprehensive LCA and guide regional input-output electricity estimates and tradeoffs in key areas; (4) demonstration and development of the greenhouse gas ROI metric, iterative hybrid LCA methodology, and supply chain layout decision-making for concentrator solar PV We note that these supply chain efforts must occur in conjunction with efforts on sustainable product design such as design for remanufacture, improved use-phase efficiencies, or utilization of new materials.

Book Description
Most people are unaware that environmental problems such as climate change can be easily avoided, at a profit, through the intelligent application of appropriate technology. The Carbon Buster's Handbook describes how to achieve this goal in the residential field. The first book in North America to provide a detailed carbon accounting of a family's carbon emissions and how to reduce them, it systematically analyzes energy costs and evaluates which measures yield the highest returns for the environment and the pocketbook. It provides answers to questions such as: Which measure is more effective: putting solar panels on your roof, or buying a hybrid car? Where do I need to invest first: in high-efficiency shower-heads, or solar tubes? Is a $500 fridge that uses 800 kWh of power per year a good buy? The book allows individuals to quickly and accurately assess which products are a good deal and which aren't. It systematically analyzes residential carbon emissions and energy costs and prioritizes solutions based on highest carbon reductions and monetary returns, yielding results that are often surprising. The book enables readers to dramatically reduce their carbon emissions - far below the levels targeted under the Kyoto Protocol. At the same time, readers implementing the recommendations will save an average of US$15,000 in energy costs over the next five years.

Book Description
Globalization and increased competition are forcing companies to review and improve their production processes to be more sustainable. However, a clear vision and environmental culture are lacking because, even today, companies are motivated to act to improve the environment essentially by compliance with government regulations and the opportunity to achieve profit growth. This book presents practices, challenges, and opportunities for the digital and sustainable transformation of business as we know it.

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
Global warming, which is caused by increasing concentrations of carbon emissions, mainly results from human activities, such as fossil fuel burning and deforestation. In order to alleviate global warming and its adverse effects, many countries including the United States and the European Union members have attempted to enact legislation or design market-based carbon trading mechanisms to control carbon emissions. Analyzing the impact of such governmental legislation on developing products has been studied, both in theory and practice. Firms need to incorporate governmental regulations and consider environmental issues and reduced carbon emission in their product development processes, this thesis presents three models for sustainable product development. All models consider environmental issues and cost for the whole life cycle of the product, from the extraction of raw materials to the end of life of the product. Three group of customer requirements are defined as cost, quality and sustainability. The objective of the models is to maximize utility to the customers for these groups of customer requirements. In all three models, three groups of customer requirements are translated to design specifications and the utility of each group is evaluated. The first model is a scoring model to compare between different designs and select the best one; the second model is an optimization model, which provides optimum value for design specifications while maximizing the total utility to the customers for the final design. And finally, the third model is a two-stage stochastic optimization model in which the weights of customer requirements are considered as uncertain parameters. This model also provides the optimum value for design specifications while modeling the weight of customer requirements as an uncertain parameter. The last two models are non-linear, non-convex models with certain conditions and are solved using the Branch-and-Reduce Optimization Navigator methodology. In all three models, Quality Function Deployment is applied to make trade-offs within each group of customer requirements and multi-attribute utility theory is used to make trade-offs between three groups of customer requirements. All three models are applied to a case study, and results show that introducing uncertainty in the parameters increases the total utility by 9.41%, and the optimization model also has the potential to help designers find an optimum design yielding higher customer satisfaction, reducing the time of product development process and making the final design more reliable based on stakeholder's opinions.
