Description
Vehicles powered by electricity and alternative-fuels are becoming a more popular form of transportation since they have less of an environmental impact than standard gasoline vehicles. Unfortunately, their success is currently inhibited by the sparseness of locations where the vehicles can refuel as well as the fact that many of the vehicles have a range that is less than those powered by gasoline. These factors together create a "range anxiety" in drivers, which causes the drivers to worry about the utility of alternative-fuel and electric vehicles and makes them less likely to purchase these vehicles. For the new vehicle technologies to thrive it is critical that range anxiety is minimized and performance is increased as much as possible through proper routing and scheduling. In the case of long distance trips taken by individual vehicles, the routes must be chosen such that the vehicles take the shortest routes while not running out of fuel on the trip. When many vehicles are to be routed during the day, if the refueling stations have limited capacity then care must be taken to avoid having too many vehicles arrive at the stations at any time. If the vehicles that will need to be routed in the future are unknown then this problem is stochastic. For fleets of vehicles serving scheduled operations, switching to alternative-fuels requires ensuring the schedules do not cause the vehicles to run out of fuel. This is especially problematic since the locations where the vehicles may refuel are limited due to the technology being new. This dissertation covers three related optimization problems: routing a single electric or alternative-fuel vehicle on a long distance trip, routing many electric vehicles in a network where the stations have limited capacity and the arrivals into the system are stochastic, and scheduling fleets of electric or alternative-fuel vehicles with limited locations to refuel. Different algorithms are proposed to solve each of the three problems, of which some are exact and some are heuristic. The algorithms are tested on both random data and data relating to the State of Arizona.

Description
As an important part of the movement for local and sustainable food in our cities, urban farming has the potential to actively involve urban dwellers in environmental, social, and economic issues of a global scale. When assessed according to a three-pillar model of sustainability, it can offer solutions to many of the major problems associated with the industrial food model that currently dominates the United States market. If implemented on a larger scale in the Phoenix metropolitan area, urban farming could improve overall environmental conditions, stimulate the local economy, and help solve food access and inequality issues. Through interviews with both amateur and established local urban farmers, this thesis attempts to identify and analyze some of the main barriers to the widespread participation in and incorporation of urban agriculture in the Phoenix Valley. Problems encountered by newcomers to the practice are compared with the experiences of more successful farmers to assess which barriers may be circumvented with proper knowledge and experience and which barriers specific to the Phoenix region may require greater structural changes.

Description
Although sustainability as a concept and a science has been around for quite some time, it has only recently come into the common vernacular of citizens around the world. While there are a number of arguments that have been and can be made about the role of sustainability in developing countries, it can be said with certainty that sustainability education, especially at the pre-university level, is commonly neglected even in countries that have sustainability initiatives elsewhere in their systems. Education is an important part of development in any country, and sustainability education is critical to raising generations who are more aware of the connections in the world around them. Informal education, or education that takes place outside of a formal classroom, can provide an especially important platform for sustainability ideas. These factors take on unique characteristics within the environment of a small island with noble sustainability goals but limited resources and an economy that includes a significant domestic goat population. After providing basic background on sustainability and the nature of the educational process within the environment of the small island-nation of Grenada, I discuss the importance of informal education and follow my path with a local non-profit in Grenada leading to the development of a locally-relevant sustainability curriculum for implementation in a K-6 school.

Description
Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in upholstery, plastics, clothing, and other products to reduce fire danger, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. By summarizing various metrics of sustainability and the mercury content in consumed species of fish and shellfish, researchers have found that high levels of chemical contamination was linked with lesser fishery sustainability. I conducted a literature review of flame retardant content in seafood to further compare contamination and sustainability in addition to the initial analysis with mercury. My review suggests that the widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are mutually disadvantageous for both human consumers and the environment. Future research should address the need for the collection of data that better represent actual global contaminant concentrations in seafood.

Description
Corporate social responsibility (CSR) is a fascinating and complex topic. There is consensus that companies both make a large impact on the world and have a responsibility beyond profits. The challenge with this responsibility is that determining businesses' responsibility and measuring the impact remains unclear. Scholars most often point to the early to mid 1900s as its starting point and the increased economic growth and workers' unions occurring in the 1950s as one of the reasons for scholars paying more attention to the topic. This thesis project analyzes current examples of CSR from Starbucks and IBM. These companies have reputations for their positive CSR practices. Both companies' availability of information, the vast number of their CSR practices, and efforts to measure the impact set them apart. IBM and Starbucks stand out because of the sheer volume of CSR activities they have, and when examined closely, the mixed, primarily good, impact of these activities is revealed. Having a high number of CSR practices alone does not equate to doing CSR well. Instead, companies' CSR should be examined based on both the number of practices and their impact. Considering both of these metrics will help consumers, as well as other stakeholders, better evaluate the success or failure of CSR in a business.

Description
Over the past two decades, the fashion industry has evolved to both create and respond to the consumer's demand for fast fashion, the industry of inexpensive clothing produced at high rates to respond to changing consumer trends. As fast fashion grew in popularity, the new standard of the industry was to create and manufacture every other week, producing continual new trends for a market designed for continual consumption. As the garments being produced were made for short life-spans, textile waste began to grow and the fashion industry was named the second largest pollutant in the world next to oil. Coming out of a market saturated with clothing, a new trend focused around sustainability and reuse has emerged: the resale market. With increased awareness for sustainability, circular fashion business models have emerged from a more linear and disposable supply chain. By focusing on environmental, social, and financial aspects of a supply chain, otherwise known as the triple bottom line, we discuss how second-hand shopping should be managed to satisfy customer shopping expectations.
The creative project of this thesis showcases various wardrobes that have solely been purchased second-hand. The purpose of the creative presentation is to show that no matter one’s style preference, occupation, or age, second hand shopping can appeal to every type of customer. Second hand shopping is not only for “thrifty” millennials, it it for everyone, and can encompass anyone’s clothing needs.

Description
Sustainability is intrinsically interdisciplinary, but the implementation of nontraditional pedagogy in this area is in its infancy. I aim to show that music can be a model to demonstrate the protean systems that consistently involve each of us. The connection between systems thinking and musical improvisation is evident in musical improvisation ensembles; it is a system unto itself with individual players connected through their musical composition. Musical improvisation allows the players to learn about systems and system behaviors. Such ability to identify and understand the underlying dynamics involved in complex social-ecological systems is fundamental to taking advantage of leverage points and working towards a sustainable future. I use music and musical improvisation to demonstrate the three concept groups of the systems thinking competency: 1) Variables, structures and functions 2) Resilience, self-organization and hierarchy and 3) Scales and domains. These parts constitute complex systems and are made easier with the analogy of music that provides a more representative language for discussing them in an intuitive way. Furthermore, improvisation activities provide a method and space for these future practitioners to rehearse working with systems. From accepting the nature of systems, one is accepting of their role in the system, which enables them to make changes. Musical improvisation is a valuable method to systems thinking because it requires future practitioners to engage in mindfulness, because it demands remaining in an intuitive stance so to be able to respond (not react) thoughtfully. My thesis will explore how the practice of musical improvisation can enhance the understanding of the three systems thinking content groups and to argue that such practice is unique and necessary as it provides opportunities to rehearse being effective change agents.

Description
The purpose of this research was to address the viability of a monoculture to polyculture agricultural land-cover transition within the context of the palm oil industry in Malaysia and Indonesia. A lifecycle assessment was used as a framework in the Cradle-to-Gate methodology used to understand sustainability hotspots, develop four future scenarios, and to measure three chosen indicators for metric changes. The four scenarios included a business-as-usual, perfect world, and two transition scenarios highlighting greenhouse gases, bio-control chemicals, fertilizer-use, and crop yield as indicators. In the four scenarios, a 1000 ha of plantation land with 140,000 palm oil trees created the backdrop for investigating nutrient cycling, cultivation methods, and the economic trade-offs of a transition. Primary literature was the main source of investigation and a wide-variety of current polyculture research helped create tangible data across the four scenarios. However, polyculture failed to address the socioeconomic barriers present in the governance, business-state, and regulations within this industry and region. An institutional analysis was conducted to investigate the political, financial, and regulatory barriers in this industry and recommend changes. It was concluded that while polyculture is an important form of environmental sustainability and can increase crop yield, the socioeconomic structure of the industry is the largest barrier to change and implement polyculture. In order for this social structure to change, it was recommended that the regulatory institutions, such as the Roundtable for Sustainable Palm Oil (RSPO), reframe their pressure points and instead focus on the interconnectedness of logging and palm oil companies with the regional governments.

Description
Brundtland’s definition of sustainability is the ability to “meet the needs of the present without compromising the ability of future generations to meet their needs” (IISD, 2021). But what if there are no future generations? Social sustainability, the sector of sustainability that foregrounds the well-being and livelihoods of people (and thereby continuation of humanity), is included in definitions within the sustainability field, but less developed in sustainability practice. In an effort to bridge this gap of knowledge, 14 U.S. cities and over 100 sustainability policies were analyzed for their social sustainability performance. An eight-item analytical framework that deals with differing areas of social equity guided the analysis. Results found that most cities’ sustainability departments fell short of truly addressing social sustainability concerns. Out of the eight items, the most frequently addressed were housing security and racial and gender equality whereas few, if any, cities addressed the more specific social concerns of immigration, technology and media, or arts/cultural preservation. Future research is recommended to gain a better understanding of the ways existing cities can improve in this area.
