abstract = {This thesis explores the ethical challenges that a potential research program for solar climate engineering via Stratospheric Aerosol Injection (SAI) could incur. These ethical challenges are comprised of epistemic hurdles in relation to the research process, as well as societal questions of justice and the value of nature. The thesis proposes a variety of tools and approaches to assess and possibly govern the risks and uncertainties invoked by the research of SAI and its societal implications. The methodological approach is based mainly on ethical and philosophical analysis and reflection and the main findings take the form of discursive argumentation and normative reflection.



SAI is a form of climate engineering that seeks to reduce global warming by increasing the planet’s reflection levels through the injection of reflective agents (aerosols) into the stratosphere. The mere potential of researching a technology that would actively intervene in the global climate is highly contentious and has led to passionate debates throughout the expert community. Designing a research process for such a polarizing technology such as SAI inevitably raises fundamental moral questions, wherein issues of global justice, democracy, the value of and humanity’s relationship with nature, and the societal impacts of technological innovation all intersect. Given these far-reaching consequences, the thesis operates under the assumption that SAI is a highly disruptive idea and technology, that has the potential to challenge and undermine existing societal values and institutions. Accordingly, this work presents a range of philosophical modes of inquiry and assessments, in order to supply any proposed SAI research governance program with the necessary ethical considerations and frameworks.



The thesis is structured along four major inflection points, which form the individual chapters tied together through differing but interrelated research questions. What follows is an overview of the research questions, along with a brief description of how those questions were answered…},
