The Anthropocene, understood from the perspective of the creators of Earth System Science and IPCC, calls for global governance, which tends to be understood as an epistocratic, technocratic affair leaving little room for reflective rationality and politics in the agonistic sense. Using the republican repertoire, I argue that global governance thus understood is actually the last thing we need. I suggest that global environmental institutions ought to be based on ‘constitutional republicanism’. Key elements of this approach are a Machiavellian appreciation (...) of discord, agonism and ‘the political’, combined with a realistic assessment of the very diverse interests at stake in global climate politics, hence very diverse ideas about the benefits and burdens of specific global environmental strategies; and institutions based on ideas uniquely developed by republicans from Machiavelli to Mouffe allowing for human and science’s fallibility on the one hand, irreducible moral and political diversity on the other.

However far we are from either in practice, basic global and intergenerational justice, including climate change mitigation, are taken to be theoretically compatible. If population grows as predicted, this could cease to be the case. This paper asks whether that tragic legacy can now be averted without hard or even tragic choices on population policy. Current generations must navigate between: a high-stakes gamble on undeveloped technology; violating human rights; demanding unbearable sacrifices of the already badly off; institutional unfairness across adults; (...) institutional unfairness across children; failing to protect children’s basic interests; and threatening the autonomy of the family. We are not yet forced to choose between bequeathing a tragic choice and making one, by adopting basically unjust measures. However, even the remaining options present a morally hard choice. The fact we face it is yet another damning indictment on the combined actions and collective failures of the global elite. (shrink)
