Description
This study investigates how well prominent behavioral theories from social psychology explain green purchasing behavior (GPB). I assess three prominent theories in terms of their suitability for GPB research, their attractiveness to GPB empiricists, and the strength of their empirical evidence when applied to GPB. First, a qualitative assessment of the Theory of Planned Behavior (TPB), Norm Activation Theory (NAT), and Value-Belief-Norm Theory (VBN) is conducted to evaluate a) how well the phenomenon and concepts in each theory match the characteristics of pro-environmental behavior and b) how well the assumptions made in each theory match common assumptions made in purchasing theory. Second, a quantitative assessment of these three theories is conducted in which r2 values and methodological parameters (e.g., sample size) are collected from a sample of 21 empirical studies on GPB to evaluate the accuracy and generalize-ability of empirical evidence. In the qualitative assessment, the results show each theory has its advantages and disadvantages. The results also provide a theoretically-grounded roadmap for modifying each theory to be more suitable for GPB research. In the quantitative assessment, the TPB outperforms the other two theories in every aspect taken into consideration. It proves to 1) create the most accurate models 2) be supported by the most generalize-able empirical evidence and 3) be the most attractive theory to empiricists. Although the TPB establishes itself as the best foundational theory for an empiricist to start from, it's clear that a more comprehensive model is needed to achieve consistent results and improve our understanding of GPB. NAT and the Theory of Interpersonal Behavior (TIB) offer pathways to extend the TPB. The TIB seems particularly apt for this endeavor, while VBN does not appear to have much to offer. Overall, the TPB has already proven to hold a relatively high predictive value. But with the state of ecosystem services continuing to decline on a global scale, it's important for models of GPB to become more accurate and reliable. Better models have the capacity to help marketing professionals, product developers, and policy makers develop strategies for encouraging consumers to buy green products.

Life Cycle Assessment (LCA) quantifies environmental impacts of products in raw material extraction, processing, manufacturing, distribution, use and final disposal. The findings of an LCA can be used to improve industry practices, to aid in product development, and guide public policy. Unfortunately, existing approaches to LCA are unreliable in the cases of emerging technologies, where data is unavailable and rapid technological advances outstrip environmental knowledge. Previous studies have demonstrated several shortcomings to existing practices, including the masking of environmental impacts, the difficulty of selecting appropriate weight sets for multi-stakeholder problems, and difficulties in exploration of variability and uncertainty. In particular, there is an acute need for decision-driven interpretation methods that can guide decision makers towards making balanced, environmentally sound decisions in instances of high uncertainty. We propose the first major methodological innovation in LCA since early establishment of LCA as the analytical perspective of choice in problems of environmental management. We propose to couple stochastic multi-criteria decision analytic tools with existing approaches to inventory building and characterization to create a robust approach to comparative technology assessment in the context of high uncertainty, rapid technological change, and evolving stakeholder values. Namely, this study introduces a novel method known as Stochastic Multi-attribute Analysis for Life Cycle Impact Assessment (SMAA-LCIA) that uses internal normalization by means of outranking and exploration of feasible weight spaces.

Description
The consumption of feedstocks from agriculture and forestry by current biofuel production has raised concerns about food security and land availability. In the meantime, intensive human activities have created a large amount of marginal lands that require management. This study investigated the viability of aligning land management with biofuel production on marginal lands. Biofuel crop production on two types of marginal lands, namely urban vacant lots and abandoned mine lands (AMLs), were assessed. The investigation of biofuel production on urban marginal land was carried out in Pittsburgh between 2008 and 2011, using the sunflower gardens developed by a Pittsburgh non-profit as an example. Results showed that the crops from urban marginal lands were safe for biofuel. The crop yield was 20% of that on agricultural land while the low input agriculture was used in crop cultivation. The energy balance analysis demonstrated that the sunflower gardens could produce a net energy return even at the current low yield. Biofuel production on AML was assessed from experiments conducted in a greenhouse for sunflower, soybean, corn, canola and camelina. The research successfully created an industrial symbiosis by using bauxite as soil amendment to enable plant growth on very acidic mine refuse. Phytoremediation and soil amendments were found to be able to effectively reduce contamination in the AML and its runoff. Results from this research supported that biofuel production on marginal lands could be a unique and feasible option for cultivating biofuel feedstocks.

Description
Ecolabels are the main driving force of consumer knowledge in the realm of sustainable product purchasing. While ecolabels strive to improve consumer's purchasing decisions, they have overwhelmed the market, leaving consumers confused and distrustful of what each label means. This study attempts to validate and understand environmental concerns commonly found in ecolabel criteria and the implications they have within the life cycle of a product. A life cycle assessment (LCA) case study of cosmetic products is used in comparison with current ecolabel program criteria to assess whether or not ecolabels are effectively driving environmental improvements in high impact areas throughout the life cycle of a product. Focus is placed on determining the general issues addressed by ecolabelling criteria and how these issues relate to hotspots derived through a practiced scientific methodology. Through this analysis, it was determined that a majority the top performing supply chain environmental impacts are covered, in some fashion, within ecolabelling criteria, but some, such as agricultural land occupation, are covered to a lesser extent or not at all. Additional criteria are suggested to fill the gaps found in ecolabelling programs and better address the environmental impacts most pertinent to the supply chain. Ecolabels have also been found to have a broader coverage then what can currently be addressed using LCA. The results of this analysis have led to a set of recommendations for furthering the integration between ecolabels and life cycle tools.

Description
I present a new framework for qualitative assessment of the current green purchasing practices of U.S. state governments. Increasing demand from citizens for green public purchasing has prompted state governments to adopt new, and improve existing, practices. Yet there has been little assessment of public green purchasing in academic research; what has been done has not provided the conceptual support necessary to assess green purchasing practices as a single component of the procurement process. My research aims to fill that gap by developing a conceptual framework with which to assess the status of green purchasing practices and by applying this framework to determine and describe the status of green purchasing in the five most populous U.S. states. The framework looks at state purchasing practices through the lenses of policy, policy implementation, and transparency.

Description
Carbon capture and sequestration (CCS) is one of the important mitigation options for climate change. Numerous technologies to capture carbon dioxide (CO2) are in development but currently, capture using amines is the predominant technology. When the flue gas reacts with amines (Monoethanaloamine) the CO2 is absorbed into the solution and forms an intermediate product which then releases CO2 at higher temperature. The high temperature necessary to strip CO2 is provided by steam extracted from the powerplant thus reducing the net output of the powerplant by 25% to 35%. The reduction in electricity output for the same input of coal increases the emissions factor of Nitrogen Oxides, Mercury, Particulate matter, Ammonia, Volatile organic compounds for the same unit of electricity produced. The thesis questions if this tradeoff between CO2 and other emissions is beneficial or not. Three different methodologies, Life Cycle Assessment, Valuation models and cost benefit analysis are used to identify if there is a net benefit to the society on implementation of CCS to a Pulverized coal powerplant. These methodologies include the benefits due to reduction of CO2 and the disbenefits due to the increase of other emissions. The life cycle assessment using ecoindicator'99 methodology shows the CCS is not beneficial under Hierarchical and Egalitarian perspective. The valuation model shows that the inclusion of the other emissions reduces the benefit associated with CCS. For a lower CO2 price the valuation model shows that CCS is detrimental to the environment. The cost benefit analysis shows that a CO2 price of at least $80/tCO2 is required for the cost benefit ratio to be 1. The methodology integrates Montecarlo simulation to characterize the uncertainties associated with the valuation models.

Description
The goal of this project is to gain and use knowledge of sustainability topics as a value-adding function for a business in the Tempe, AZ area and to develop the skills to approach and consult with business owners and staff about sustainable business options. Sustainability searches for a balance between society, economy and the environment where all three can thrive; therefore, the ideal project partner was a business that values the wellbeing of mankind, is locally owned and operated and promotes environmental stewardship. The Original Chop Shop Co in Tempe Arizona was appropriately selected. Throughout the duration of our partnership, I observed their daily routine, interviewed employees and managers and used the collected information to identify three areas of focus that have the largest potential to reduce The Original Chop Shop Company's impact on the environment. Information on the areas of recycling, composting, and food sourcing was researched and synthesized to make suggestions for ecofriendly changes to business practices. The scope of the project includes small changes in daily practices such as implementing a recycling and composting program and employee training sessions and minor investments such as purchasing a micro washer and silverware in order to eliminate nonrenewable plastic utensils. The scope does not include major renovations or investments in technology. The suggestions offered position The Original Chop Shop to conduct business in a way that does not compromise the health of the environment, society, or economy.

Description
This thesis conducts research into the emissions from ocean going vessels and the ports that they dock at and current methods that are being pursued to help reduce the environmental impact of the ocean shipping industry. The main emissions from the industry analyzed are particulate matter, oxides of nitrogen, oxides of sulfur and greenhouse gases. One method of reducing the environmental impact of the industry is through the improvement of the vessels. The vessels are currently being improved through the exploration of using liquefied natural gas (LNG) instead of bunker fuel. It has been found that LNG takes up less space, costs less, and has fewer emissions compared to bunker fuel, making it an ideal replacement as a fuel source. In addition to changing fuel sources, the International Maritime Organization (IMO) has created emission control areas around the United States and its territories mandating the use of ultra-low sulfur diesel within a certain range of land. There are two emission control areas with one being for the United States, Canada, and the French Territories of North America and the other for Puerto Rico and the U.S. Virgin Islands. For the North American nations it is 200 nautical miles, while for Puerto Rico and the U.S. Virgin Islands it is 50 nautical miles. This is an external pressure encouraging current shipping companies to switch to LNG as a fuel source. A second method of reducing the environmental impact of the ocean shipping industry is to improve the ports. The ports are being improved by utilizing alternative maritime power, reducing the emissions of vehicles at the ports, and engaging all of the stakeholders of a port. Alternative maritime power (AMP) is the use of shore-side power sources to power the auxiliary engines of vessels while they are hotelling, at dock. AMP is also referred to as cold-ironing and is effective in reducing emissions from vessels because the auxiliary engines are powered by electricity as opposed to fuel. This is an expensive option to pursue because of the high investment costs, but the Carl Moyer Program provides analysis for the cost-effectiveness of projects to justify the high costs. The second facet of port improvements is decreasing the emissions from all vehicles at the ports. The Port of Los Angeles has gradually been phasing out trucks with old engines and even banning them from entering the port. Cargo handling equipment has seen similar restrictions to reduce emissions. Finally locomotives have seen requirements implemented causing them to improve their engines while implementing idling restriction technologies as well. These improvements have yielded tangible and effective results for the Port of Los Angeles. These initiatives have resulted in a decrease in emissions from the port since their inception in 2005 to 2011 (2011 being the last year that data is available). In that time frame diesel particulate matter has been reduced by 71% at 634 tons, NOx has been reduced by 51% at 8,392 tons and SOx has been reduced by 76% at a total of 4,038 tons. The final part of port improvements this paper looks into is the integration and engagement of all stakeholders. The Port of Los Angeles has all but approved the Southern California International Gateway Project (SCIG) by Burlington Northern Santa Fe (BNSF) Railway. This project included the cooperation of BNSF, local unions, and local politicians to create a new rail yard that contains the highest sustainability standards for any rail yard. SCIG will employ numerous local people, require trucks to take alternative routes, reduce the amount of trucks on the highway, and help get products to consumers more competitively and efficiently. This will result in reduced emissions, decreased noise pollution, and less traffic congestion on Los Angeles highways. In conclusion it was found that real, effective, and cost-effective projects are being undertaken to improve the environmental impacts of the ocean shipping industry.
