It has been argued that the most impactful choice an individual could make, with respect to mitigating greenhouse gas emissions, is to have fewer children. This paper brings up a related aspect of individuals’ reproductive choices that has been neglected in the climate ethics literature: the timing aspect. It is argued that, from a climate change perspective, it does not matter only how many children people bring into existence, but also when they are brought into existence. The reason is that (...) the age at which parents choose to procreate affects the number of people that will live simultaneously on the planet, which is in turn relevant for climate change. This provides individuals another means by which they can decrease their emissions. (shrink)

In this paper I analyse how procreative freedom poses a challenge for rule-consequentialism. First, I reconstruct the rule-consequentialist case for procreative freedom. Second, I argue that population scenarios resulting from very low fertility pose a problem for rule-consequentialism since such scenarios cannot secure population growth or even avoid human extinction in the long run. Third, I argue that population scenarios resulting from excessive procreation also pose a problem for rule-consequentialism since they are incompatible with the promotion of optimific consequences in (...) various ways. Were the rule-consequentialist to avoid these types of scenarios, the challenge would consist in doing so while retaining the liberal approach to individual rights and freedoms that made rule-consequentialism an advantageous competitor against moral theories like act-consequentialism. These population scenarios raise more general questions about how rule-consequentialism ought to conceptualise the application of universal rules in the long-term, intergenerational context. This is an important place for inquiry given that rule-consequentialism is originally conceived as a forward-looking theory. (shrink)
