    Moral obligations of states
    In Applied Ethics Series, Centre For Applied Ethics and Philosophy, Hokkaido University. pp. 86-93. 2011.
    The starting point of the paper is the frequent ascription of moral duties to states, especially in the context of problems of global justice. It is widely assumed that industrialized or wealthy countries in particular have a moral obligation or duties of justice to shoulder burdens of poverty reduction or climate change adaptation and mitigation. But can collectives such as states actually hold moral duties? If answering this affirmatively: what does it actually mean to say that a state has mor…Read more

    Defining Terrorism
    In Terrorism: A Philosophical Enquiry, Palgrave-macmillan. pp. 7-47. 2012.
    Without doubt, terrorism is one of the most vehemently debated subjects in current political affairs as well as in academic discourse. Yet, although it constitutes an issue of general socio-political interest, neither in everyday language nor in professional (political, legal, or academic) contexts does there exist a generally accepted definition of terrorism. The question of how it should be defined has been answered countless times, with as much variety as quantity in the answers. In academic …Read more

    Is there an obligation to reduce one’s individual carbon footprint?
    Critical Review of International Social and Political Philosophy 17 (2): 168-188. 2014.
    Moral duties concerning climate change mitigation are – for good reasons – conventionally construed as duties of institutional agents, usually states. Yet, in both scholarly debate and political discourse, it has occasionally been argued that the moral duties lie not only with states and institutional agents, but also with individual citizens. This argument has been made with regard to mitigation efforts, especially those reducing greenhouse gases. This paper focuses on the question of whether i…Read more

    Rethinking legitimate authority
    In Fritz Allhoff, Nicholas Evans & Adam Henschke (eds.), Routledge Handbook of Ethics and War: Just War Theory in the 21st Century, Routledge. 2013.
    The just war-criterion of legitimate authority – as it is traditionally framed – restricts the right to wage war to state actors. However, agents engaged in violent conflicts are often sub-state or non-state actors. Former liberation movements and their leaders have in the past become internationally recognized as legitimate political forces and legitimate leaders. But what makes it appropriate to consider particular violent non-state actors to legitimate violent agents and others not? This arti…Read more

    Joint Duties and Global Moral Obligations
    Ratio 26 (3): 310-328. 2013.
    In recent decades, concepts of group agency and the morality of groups have increasingly been discussed by philosophers. Notions of collective or joint duties have been invoked especially in the debates on global justice, world poverty and climate change. This paper enquires into the possibility and potential nature of moral duties individuals in unstructured groups may hold together. It distinguishes between group agents and groups of people which – while not constituting a collective agent – a…Read more

    Joint Moral Duties
    Midwest Studies in Philosophy 38 (1): 58-74. 2014.
    There are countless circumstances under which random individuals COULD act together to prevent something morally bad from happening or to remedy a morally bad situation. But when OUGHT individuals to act together in order to bring about a morally important outcome? Building on Philip Pettit’s and David Schweikard’s account of joint action, I will put forward the notion of joint duties: duties to perform an action together that individuals in so-called random or unstructured groups can jointly ho…Read more

    Terrorism: A Philosophical Enquiry
    Palgrave-Macmillan. 2012.
    This book engages with the most urgent philosophical questions pertaining to the problem of terrorism. What is terrorism? Could it ever be justified? Assuming that terrorism is just one of many kinds of political violence, the book denies that it is necessarily wrong and worse than war. In fact, it may be justifiable under certain circumstances.

    This essay investigates the possibilities and limits of interdisciplinary research into terrorism. It is shown that approaches that combine philosophy and international law are necessary, and when such an approach needs to be adopted. However, it is also important not to underestimate how much of a challenge is posed by the absence of agreement concerning the definition of terrorism, and also by the structural differences in the way the two disciplines address the problem and formulate the issue…Read more

    Bridging The Emissions Gap: A Plea For Taking Up The Slack
    Philosophy and Public Issues - Filosofia E Questioni Pubbliche 3 (1): 273-301. 2013.
    With the existing commitments to climate change mitigation, global warming is likely to exceed 2°C and to trigger irreversible and harmful threshold effects. The difference between the reductions necessary to keep the 2°C limit and those reductions countries have currently committed to is called the ‘emissions gap’. I argue that capable states not only have a moral duty to make voluntary contributions to bridge that gap, but that complying states ought to make up for the failures of some other s…Read more

    Polycentric Systems and the Integrity Approach
    In Hugh Breakey, Vesselin Popovski & Rowena Maguire (eds.), Ethical Values and the Integrity of the Climate Change Regime, Routledge. pp. 131-138. 2015.
    The starting point of this chapter is the observation that at the global level the climate system is failing to produce the outcomes it was set up to produce and as such is lacking consistency integrity. That is, it is failing to act in accordance with its public institutional justification and the values embodied in it. However, emerging so-called polycentric systems are increasingly successful at addressing the challenges of global climatic change, according to economist Elinor Ostrom. The aim…Read more
