Language, knowledge, power: The Discursive Construction of Climate Engineering Governance

In addition to mitigation and adaptation as strategies for governing climate futures, a third way of responding to climate change is now emerging: Intentional intervention into the global climate, often termed ‘climate engineering’ (CE). There is a growing awareness that formal governance of some types of CE is going to be needed in the coming years, and that informal governance is already being shaped by the discourses and practices of CE research and assessment. Increased attention is being paid to the types of scientific and societal discourses shaping the emergence of CE governance. Contributing to this literature, this thesis asks how the discursive construction of CE governance is taking place in science, industry, civil society, and politics. The project emphasises that, as discourse is the source code with which contested futures are written, ‘cracking the discursive code’ underpinning the CE governance debate can help critically anticipate the emergence of future governance practices and infrastructures. In this vein, the thesis peruses several interrelated aims: (1) Exploring a framework for shifting the analytical perspective on the role of discourse in (CE) governance development processes; (2) Anticipating and critically reflecting upon how given discursive structures may be making certain types of CE governance more/less thinkable and practicable, (3) emancipating those engaging in the CE governance debate to recognize and expand the bounds of the discursive structures they are reproducing, and (4) informing the design of participatory processes to further “open up” discursive diversity in CE governance development.
