One of the most provocative claims in current climate ethics is that we ought to have fewer children, because procreation brings new people into existence and thereby causes large amounts of additional greenhouse gas emissions. The public debate about procreation and climate change is frequently framed in terms of the question of whether people may still have any children at all. Yet in the academic debate it is a common position that, despite the large carbon impact of procreation, it is (...) still permissible to have one or two children per couple, if having children is needed for the parents' lives to go well. In this article, we propose a defence and a principled formulation of this procreative prerogative: agents are permitted to procreate if the goods that procreation provides are essential to their lives going well and cannot be replaced by other goods, nor be realized by lower‐emissions alternatives. This principle implies that procreative decisions require case‐by‐case assessment in which agents' self‐reflection, individual circumstances, and social context play a significant role. (shrink)

Several climate ethicists have recently argued that having children is morally equivalent to over-consumption, and contributes greatly to parents’ personal carbon footprints. We show that these claims are mistaken, for two reasons. First, including procreation in parents’ carbon footprints double-counts children’s consumption emissions, once towards their own, and once towards their parents’ footprints. We show that such double-counting defeats the chief purpose of the concept of carbon footprint, namely to measure the sustainability and equitability of one’s activities and choices. Furthermore, (...) we show that proposals to avoid double-counting have other unacceptable implications. Second, we show that the key arguments for a supposed moral equivalence of procreation and consumption overgenerate and lead to unacceptable consequences in many cases, such as for the work of doctors who save lives or enable procreation. Finally, we propose that rather than counting children’s emissions towards their parents’ carbon footprints, we should consider these emissions as part of the parents’ carbon impact, i.e. the difference that their choices make to the overall global carbon emissions. It is from the perspective of impact that we should think about the ethics of procreation in an age of climate change. (shrink)

In this article, I challenge the widespread presumption that a child should have exactly two parents. I consider the pros and cons of various numbers of parents for the people most directly affected – the children themselves and their parents. The number of parents, as well as the ratio of parents to children, may have an impact on what resources are available, what relationships can develop between parents and children, what level of conflict can be expected in the family, as (...) well as the costs involved in parenting and the experience of parenting a child. Indirectly, there is also an effect on who will have the opportunity to be a parent, as well as on wider social issues that I mention but do not discuss. Having considered all these factors, I conclude that there is some reason to believe that three or more parents is usually better than one or two, especially if children are to have siblings, which is typically beneficial. However, these reasons are not strong enough to support a general presumption in favor of any particular number. We should therefore jettison the two‐parent presumption and make different numbers of parents more socially accepted as well as legally possible. (shrink)

This paper examines the legitimacy of retrospective parental rights-claims through the lens of so-called ‘thwarted father’ cases: men who are unaware of their progeny’s existence until the window for establishing legal parentage (and associated rights) has passed. In some famous cases of thwarted fathers, courts have found that an injustice has been done which must be rectified by awarding retrospective parental rights and custody to those men, even when their genetic child has already lived for some extended period with their (...) adoptive parents. In this paper, I critically examine Norvin Richards’ liberty-based defence of the parental rights of these fathers. He argues that the decision to overturn an adoption in a thwarted father case is justified if we agree that a man’s contribution of sperm was indeed the first act of a parenthood project that he should have had the liberty right to continue. Although Richards’ account might allow us to say that a thwarted father has been wronged, justice cannot demand that the situation be rectified through specific performance (as in cases when property is stolen and justice requires that it be returned).
