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.

This project is creating a non-profit green building organization called AZ Build Green Coalition. There is currently no statewide neutral organization for knowledge sharing about various green building initiatives throughout Arizona. Multiple municipalities in the state are now interested in and starting to execute green building initiatives through varied processes. Yet, each municipality is remaking the wheel and select green building champions in each city usually lead these efforts without a lot of funding or capacity. A central source for knowledge sharing and education would be instrumental in facilitating faster and more efficient movements with green building initiatives and codes. For example, the city of Scottsdale is in the process of being the first municipality in the nation to adopt the newest version of the International Green Construction Code (IgCC). This project has been involved in and aided in that initiative. The city of Tempe has initiated three IgCC 2018 pilot projects. Other municipalities in the state are interested in the IgCC and several have previously adopted it on a voluntary basis. Sharing resources and code approval barriers through a central forum would be beneficial for faster progress and also navigating the political barriers more effectively. The non-profit aims to assist with this collaboration and future high performance building initiatives through tools such as: public presentations, a central sharable document repository, an online presence, and other collaborative tools.

Underserved communities are disproportionately impacted by climate change, and current inequities present in our emissions-heavy transportation system only exacerbate these burdens. As of 2019, transportation accounted for 29% of total GHG emissions in the United States. Electric Vehicles (EVs) present an opportunity to lower emissions associated with transportation, as EVs emit zero tailpipe emissions. We define electric vehicles as cars, bikes, scooters, buses, and rail systems. As transitions to EVs occur, action can be taken to adopt more equitable practices within the transportation space, specifically in historically underserved communities.

In partnership with The City of Phoenix’s EV Department, and with additional support from the Housing Department, the EV Changers team developed a transportation-oriented survey to be distributed to the Edison-Eastlake Community (EEC) in Phoenix. Efforts to understand the EEC’s needs will lend to more efficient, connected, and accessible transportation in the upcoming transportation electrification movement.
