| Abstract: | Current analyses of pathways limiting global warming to well below 2°C, as called for in the Paris Agreement, do not consider the climate impacts already occurring below 2°C. Here we show that accounting for these 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 time that damages persist and in the climate sensitivity. We find that carbon prices in 2030 are higher compared to the case where only the 2°C is considered; the median value is $115 per tonne of CO2. The long-term persistence of damages, while highly uncertain, is a main driver of optimal near-term climate policy. Accounting for damages on economic growth increases the gap between the currently pledged nationally determined contributions and the welfare-optimal 2030 emissions for 2°C by two thirds, compared to pathways considering the 2°C limit only. |

| Abstract: | Negative environmental externalities associated with wind power plants depend on the physical characteristics of turbine installations and associated power lines and the geographical siting. We derive analytically an environmental taxation scheme for achieving the efficient spatial distribution of new wind power production, taking account of both production and environmental costs. Further, we illustrate the analytical results by means of a detailed numerical energy system model for Norway. We show that a given target for wind power production can be achieved at a significantly lower social cost by implementing a tax scheme, compared to the current situation with no environmental taxes. We also show that the environmental costs associated with both turbines and power lines were crucial to the efficient spatial allocation of wind power plants. |
