(1) The exceedingly small but fully real effects of my greenhouse gases
(2) A threshold phenomenon?
In the previous posts in this series, I have argued that individual greenhouse gas emissions have an exceedingly small but fully real effect: they are sufficient to increase the risk that vulnerable people suffer from climate change harms and necessarily do so. What follows from this, normatively speaking? In this post, I will argue that it provides a strong reason for a unilateral individual duty to reduce one’s greenhouse gas emissions.
To be more precise about the responsibility and the duties of individuals, I will first differentiate between emissions that are avoidable on the individual level, and those that are not. Subsequently, I will defend the claim that individuals have a duty to reduce their avoidable emissions in order not to increase the risk that vulnerable people suffer from climate change harms. Moreover, I will refute the assertion that unilateral actions to reduce emissions are ineffective, while promotional actions supposedly are effective.
