One solution to the problems of poor air quality in Phoenix, Arizona and global climate change is to alter the way the population uses transportation. In the US, around one-fifth of all carbon dioxide (CO2) emissions are due to cars and trucks used for transportation and the increasing level of CO2 emissions is exacerbating our impact on the climate and is causing a shift in climate. By switching from combustion engine vehicles to public transportation, electric vehicles, or going entirely vehicle-less, the amount of CO2 being released into the atmosphere every day will be decreased and overall air quality within cities will improve. If public transportation, riding a bicycle or walking is not an option, electric vehicles (EVs) are ideal as a lower-carbon emitting option over traditional combustion engines when they are recharged using renewable energy sources, like solar.
To encourage the adoption of EVs, this project pushed to overcome a few of the traditional barriers to adoption – initial cost, charging station infrastructure, and education about EVs. First, charging infrastructure was installed on all four ASU campuses. Then, to discover the biggest barriers to EV adoption, a literature review was conducted to develop a general understanding of barriers which guided the creation of survey questions. This survey was distributed to all staff and faculty at ASU (over 9,500 individuals) and received over 1,400 responses. To begin building the EV program at ASU, other universities with EV programs were interviewed to learn best practices and to understand what is most effective in encouraging EV adoption on campus. The responses determined that ASU needs to:
1. Install more charging stations on campus.
2. Offer premium parking for EV/hybrid users or a discounted parking pass or free charging.
3. Add charging stations to ASU interactive map.
4. Develop an incentive program with EV dealerships.
The project built partnerships with EV dealerships to lower the initial costs associated with buying and leasing EVs. Finally, to increase awareness of EVs, the dealership partners brought EVs to campus for a demonstration day paired with Earth Day. The ASU EV program will reduce barriers to EV adoption to help reduce CO2 emissions related to transportation at the ASU campuses and improve city air quality.
The American food system creates a significant amount of waste and relies on significant energy, land, and freshwater inputs, accounting for a large amount of the United States GHG emissions (US EPA, 2009). Across the supply chain, a total of 40-50% of all food is not consumed. Reducing food waste is a way to decrease the impacts of the food system across the supply chain. At present, restaurants do not know of options available to them to mitigate their food waste and decrease their impact on climate change. For this project I partnered with Local First Arizona to use food recovery, or donating unused food to organizations that serve food insecure people, as an attempt to close the loop between the food that is being wasted and those who struggle to meet their caloric needs. The restaurants at Devour Culinary Classic, a weekend long food festival in Phoenix, AZ, received information about food donation and were prompted to donate at the end of the event. In total, 24 restaurants donated food, diverting 500 pounds of food, or 7% of all diverted waste, from the event’s waste stream. Donations were given to refugees recently released from ICE custody through a partnership with Arizona Jews for Justice. Following the event, recommendations on how to improve the project in future years were given to Local First Arizona in the categories of organization & logistics, marketing, communication, financial, and sustainability. A diffusion of innovation framework was used to identify the barriers faced by restaurants and analyzed how food festivals are a way to overcome those barriers.
Domestic energy is an important component of our day to day lives and is something we cannot live without. Imagine how life would be without a means to cook our food, to warm our house, life would be unbearable. As we enjoy these comforts rarely do we stop to think what the opportunity cost is. For those using renewable sources, it is not a big issue, but for those who rely on wood fuel, they have to strike a delicate balance between need for fuel and the need to conserve the greatest support systems of their livelihoods, the forests. The main source of energy for households in many developing countries is biomass, mainly from forests and woodlands. The continued use of firewood and charcoal fuel puts a strain on forests, resulting in adverse effects on the environment such as prolonged droughts, loss of biodiversity, dwindling water resources, changing weather patterns among other sustainability challenges. An alternative to firewood to charcoal lies in biochar briquettes. This paper discusses the role of biochar briquettes in mitigating climate change and serves as a step by step guide on how biochar briquettes may be produced.
Cities with a car-oriented mobility system are significant consumers of energy and require drastic transformations in their structure and function to minimize their harmful impacts on environment and people and to achieve sustainability goals. To promote such sustainable transformations, municipal administrators need to act as change-agents. Because municipal governments are often not agile organizations, they tend toward incrementalism even in the pursuit of transformational goals. Therefore, there is a need in municipal governments to build individual transformative capacity so that municipal administrators can design, test, and implement plans, projects, and policies that are capable of transforming cities toward sustainability. This research presents a game-based workshop, “Stadt-liche Ziele” (AudaCity), that uses a backcasting approach to make municipal administrators build a sustainability strategy. I conducted a pilot study to test the effects of the game on municipal administrators’ confidence in their own ability and power to implement sustainability actions, a key determinant of transformative capacity. Five municipal administrators from Lüneburg, Germany, working on mobility issues, participated in a three-hour-workshop playing the game. Interviews and questionnaires were used before and after the workshop and participants’ contributions during the event were recorded to explore collective changes in confidence. Results indicate that the game increased participant confidence by rewarding collective success, breaking down an ambitious goal into achievable tasks, and acknowledging how administrators’ current actions already contribute to the goal.
The photographs focused on aspects of life and behaviors that have contributed to happiness in local communities. A website was created and a gallery event was mounted for public review and discussion. Gallery attendees and website visitors were asked to complete a survey to assess (1) gained knowledge of sustainability solutions, and (2) how effective a tool photography is as a means of sustainability solutions communication.
This visual medium allowed people think about how to incorporate sustainable community solutions into their own lives and may have changed people’s interest in, and thoughts about, overall sustainability and sustainable solutions. The survey results demonstrated that photographs can successfully communicate sustainability ideas. Specifically, viewers gained an increased awareness of how community and urban gardening can increase happiness, well-being, and sense of community. This visual approach can continue to be used to more successfully communicate additional sustainability solutions ideas and methods to the public.
