["Journal of Social Philosophy, Volume 57, Issue 2, Page 219-229, Summer 2026. ", "\nABSTRACT\nWe claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts. By understanding these mechanisms, we can better articulate the obligation for climate leadership across various sectors, from government to individual actors, in the fight against climate change.\n"]
