Libertarianism and Climate Change Olle Torpman Academic dissertation for the Degree of Doctor of Philosophy in Practical Philosophy at Stockholm University to be publicly defended on Thursday 26 May 2016 at 10.00 in hörsal 3, hus B, Universitetsvägen 10 B. Abstract In this dissertation, I investigate the implications of libertarian morality in relation to the problem of climate change. This problem is explicated in the first chapter, where preliminary clarifications are also made. In the second chapter, I briefly explain the characteristics of libertarianism relevant to the subsequent study, including the central non-aggression principle. In chapter three, I examine whether our individual emissions of greenhouse gases, which together give rise to climate change, meet this principle. I do this based on the assumption that we are the legitimate owners of the resources we use in those activities. In the fourth chapter, I question this assumption and scrutinize libertarianism’s restrictions on appropriations of climate-relevant resources, which leads me to distinguish between some different versions of the libertarian view. Toward the end of the chapter, I also examine libertarianism’s answer to the political question regarding how emission rights should be distributed. The fifth chapter investigates libertarianism’s verdicts for mere risks of infringement, as stemming from people’s emissions and acts of appropriations. In chapter six, I investigate the libertarian right to self-defense against both the effects of climate change and other people’s climate-relevant activities. In chapter seven, I discuss two intergenerational issues related to climate change: what libertarianism says concerning future generations and how libertarianism might deal with the problem of historical emissions. The eighth chapter explores the implications of libertarianism regarding collective moral wrongdoing in connection to climate change. In chapter nine, I take a look at the libertarian room for governmental responses for tackling climate change. The tenth and final chapter is a summary. The overall conclusion of the dissertation is that libertarianism recommends that we reduce our emissions and decrease our extraction of natural resources such as forests and fossil fuels. Furthermore, governments are permitted to undertake some quite substantial actions in order to fight the causes of climate change. I end with some bottom-up reflections on what these conclusions might say about the plausibility of libertarianism. I claim that although libertarianism after all manages to explain some of our moral intuitions regarding climate change, it is questionable whether libertarianism’s explanation is better than those offered by alternative moral theories. Keywords: libertarianism, self-ownership, rights, individualism, emissions, climate change, boundary-crossing, infringement, compensation, rectification, appropriation, self-defense, future generations.

It was to be given at Lund University at the end of the month. I decided to join Daniel and successfully applied to the course. At the day of our departure to Lund, however, a technical problem had me stuck in the subway on my way to the train station in Stockholm. And once I arrived there, the train to Lund departed right before my eyes. I tried to get on board, but the doors were locked. Daniel was waving from inside the train, leaving me and Stockholm for Lund and libertarianism. I was upset and decided to cancel my enrollment in the course. Luckily, however, Daniel persuaded me over the phone to give it one more try. If he had not done that, I would most certainly never have written this – or perhaps any – dissertation. In- deed, prior to October 2013, the draft to my dissertation was nothing but a mishmash of notes on topics such as moral uncertainty, ethical subjectivism, environmental pragmatism, the value of humanity’s
