Abstract
Without risking hyperbole, climate change is the greatest political challenge humanity has ever faced. The world must achieve net-zero emissions by mid-century if the most catastrophic damage is to be avoided. The prospect of environmental transformation is most remote for major fossil fuel-exporting countries. Yet amongst the world’s largest exporters of carbon, three countries are more likely to make a transition: Australia, Canada and Norway. Across these three countries, significant climate policy variation exists. Norway developed an early, broad, diverse and durable suite of climate policies compared to Australia and Canada. In this dissertation, I explain the climate policy variation of these three countries and why responses from sympathetic governments were able to make headway and entrench policies in some cases but not others. A novel analytical framework is created to explain these outcomes using within-case process tracing and a comparative case study. Data is obtained largely through interviews with 124 informants and primary document analysis.
My central finding is that the governance foundations of climate policy are critical in explaining climate policy. State strength matters. A strong and democratic state has the potential to assuage the political risk facing economic and regime elites from climate policy. It can restructure policy networks to empower civil society so that transformative climate policy is more likely to be announced and implemented. State strength can explain why switching governments in Australia and to some degree in Canada, as opposed to Norway, meant slow shifts and easy reversal.
This dissertation contributes in several ways to the scholarship on comparative environmental politics and green state political theory. First, it foregrounds the role of the state in comparative environmental politics by emphasizing the unique and critical role that states play in providing the governance foundations needed to domestically decarbonize. Second, it theorizes linkages that can reconcile the green state literature with the economic growth imperative and the biogeochemical limits of the planet. Lastly, it provides theoretical insights into the transformative and democratic role of the strong state in addressing climate change by stressing inclusivity throughout the policymaking process.
