PHIL2116 Lecture Notes - Lecture 10: Climate Change Mitigation, Distributive Justice, Pareto Efficiency
Document Summary
L10 should a climat e t reat y make all cou nt ri es bett er off: climate trajectories and targets. What is bad about climate change: to do with rapid and thus disruptive changes in natural systems, ultimately detrimental to human well-being. Ideally we would like to know exactly how the distribution of well-being going into the future would look under various alternative global trajectories. While there have been efforts to calculate optimal climate policy based on time-discounted average utilitarian total over time (cid:894)see, e. g. , dispute (cid:271)et(cid:449)ee(cid:374) no(cid:396)dhaus a(cid:374)d ste(cid:396)(cid:374) assess(cid:373)e(cid:374)ts(cid:895) . So what are the costs of climate change: costs of adaptation, costs of failures to adapt, costs of mitigation. Implicit baseline: a world with no climate change (first two, business as usual (third) Either way, we get the result, roughly speaking: rich, developed countries should pay the bulk of the costs of climate change, huge distributions in terms of global comparative wealth, ente (cid:858)inte national pa etianism(cid:859)
