With an economically
optimal carbon price in place, global carbon emissions would actually continue to rise through the rest of this century, increasing about 50 percent from current levels.
The five columns are: Item; Units; «
Optimal carbon price» policy; «Low - cost backstop» policy; Table (reference to the Table number in Nordhaus (2008).
We calculate that the economically
optimal carbon price or carbon tax would be $ 27 per metric ton in 2005 in 2005 prices.
Table 5 - 1)
Optimal carbon price policy 2.61 Low - cost backstop policy 0.9
Table 5 - 3)
Optimal carbon price policy 5.23 Low - cost backstop policy 17.63 ratio 3
The analyses published in Nordhaus (2008)[2] show the «cost competitive alternative to fossil fuels» policy (called «Low - cost backstop policy») is far better than the «
Optimal carbon price» policy.
Not exact matches
Depending on how climate impacts unequally affect the rich or poor within every region, the
optimal policy may involve a lenient or sharp increase in the
price of
carbon over the next decades (lenient when impacts are proportional to income, sharp when impacts are concentrated on the poor).
A higher population leads to a higher
carbon price but a lower
optimal peak temperature; this is because it is even more important to limit temperature rise when there are more future people who will suffer the damages.
The main argument for a
carbon tax rather than a trading scheme is that, if there is a lot of uncertainty about the cost of reducing emissions, and not much uncertainty about the damage caused by climate change, a fixed
price for emissions (that is, a tax) will get closer to the
optimal outcome than a fixed quantity.
Here's how to get rid of black
carbon from electricity generation, cut GHG emissions by 13 Gt CO2 / a by 2050 (same as the Nordhaus «
Optimal»
carbon price policy) and achieve a lot more benefits as well.
«Economic incentives can be shifted certainly by putting the
optimal price on
carbon sequestration of the forests,» she said.
Europe has a $ 40 per ton
price on
carbon dioxide, about five times the
optimal level recommended by the model favored by Manzi, and yet the continent is still set to build 50 new coal plants over the next five years.
Renowned economics professor Robert Pindyck of Massachusetts Institute of Technology has recently canvassed the value of so - called «integrated assessment models», which attempt to calculate the
optimal social
price for emitting a tonne of
carbon given its ultimate impact on the climate and the economy.
And this cost projection assumes
optimal conditions — the immediate implementation of a common global
price or tax on
carbon dioxide emissions, a significant expansion of nuclear power and the advent and wide use of new, low - cost technologies to control emissions and provide cleaner sources of energy.
