Description
This paper will explore the existing relationship between direct air capture (DAC)technology and energy justice (EJ) principles. As DAC is a nascent technology that is
transitioning from the R&D phase to the deployment phase, a standard for typical scaling
practices has not yet been established. Additionally, since the industry of DAC aims to
capture at least 10 gigatonnes of carbon dioxide per year by 2050, and at least 20 Gt/yr by
2100, the scaling practices of this technology will have a significant impact on
communities around the world. Therefore, in this thesis I argue that if DAC is not scaled
equitably, it will negatively impact the communities hosting the technology, and would
develop a negative reputation which could slow down the overall scaling process. On the
flip side, if DAC is scaled equitably, then it could create a positive effect by being
deployed in underserved and marginalized communities and providing an economic
benefit. This could result in DAC having a positive reputation and scaling more rapidly.
In order to understand how the field viewed the integration of EJ principles into the
scaling process, I interviewed representatives from DAC companies, experts in energy
justice from NGOs and academia, and local government officials. These interviews were
semi-structured, open-ended and conducted anonymously. Through these interviews I
was able to refine my arguments and put forward a set of guidelines that the industry
could use to scale DAC with equity and justice as core principles.

Description
Research confirms that climate change is primarily due to the influx of greenhouse gases from the anthropogenic burning of fossil fuels for energy. Carbon dioxide (CO2) is the dominant greenhouse gas contributing to climate change. Although research also confirms that negative emission technologies (NETs) are necessary to stay within 1.5-2°C of global warming, this dissertation proposes that the climate change problem has been ineffectively communicated to suggest that CO2 emissions reduction is the only solution to climate change. Chapter 1 explains that current United States (US) policies focus heavily on reducing CO2 emissions, but ignore the concentrations of previous CO2 emissions accumulating in the atmosphere. Through political, technological, and ethical lenses, this dissertation evaluates whether the management process of CO2 emissions and concentrations in the US today can effectively combat climate change.
Chapter 2 discusses the historical management of US air pollution, why CO2 is regulated as an air pollutant, and how the current political framing of climate change as an air pollution problem promotes the use of market-based solutions to reduce emissions but ignores CO2 concentrations. Chapter 3 argues for the need to reframe climate change solutions to include reducing CO2 concentrations along with emissions. It presents the scientific reasoning and technological needs for reducing CO2 concentrations, why direct air capture (DAC) is the most effective NET to do so, and existing regulatory systems that can inform future CO2 removal policy. Chapter 4 explores whether Responsible Innovation (RI), a framework that includes society in the innovation process of emerging technologies, is effective for the ethical research and deployment of DAC; reveals the need for increased DAC governance strategies, and suggests how RI can be expanded to allow continued research of controversial emerging technologies in case of a climate change emergency. Overall, this dissertation argues that climate change must be reframed as a two-part problem: preventing new CO2 emissions and reducing concentrations, which demands increased investment in DAC research, development, and deployment. However, without a national or global governance strategy for DAC, it will remain difficult to include CO2 concentration reduction as an essential piece to the climate change solution.
