Economic damages from on-going climate change imply deeper near-term emission cuts
Pathways toward limiting global warming to well below 2 ^∘ C, as used by the IPCC in the Fifth Assessment Report, do not consider the climate impacts already occurring below 2 ^∘ C. Here we show that accounting for such damages significantly increases the near-term ambition of transformation pathways. We use econometric estimates of climate damages on GDP growth and explicitly model the uncertainty in the persistence time of damages. The Integrated Assessment Model we use includes the climate system and mitigation technology detail required to derive near-term policies. We find an optimal carbon price of $115 per tonne of CO _2 in 2030. The long-term persistence of damages, while highly uncertain, is a main driver of the near-term carbon price. Accounting for damages on economic growth increases the gap between the currently pledged nationally determined contributions and the welfare-optimal 2030 emissions by two thirds, compared to pathways considering the 2 ^∘ C limit only.
