year emission reduction rate in such dramatic technology turnovers will exceed 5 percent after about 2020, which makes the 70 - percent target infeasible for all practical purposes.»

Requires the EPA Administrator, by 2025 and every five
years thereafter, to review the standards for new covered EGUs and reduce the maximum carbon dioxide
emission rate for new covered EGUs to a
rate that reflects the degree of
emission limitations achievable through the application of the best system of
emission reduction that has been adequately demonstrated.

rate of
reduction varies based on peak
year, adding in the new estimated 2017
emissions.
-- Not later than 2025 and at 5 -
year intervals thereafter, the Administrator shall review the standards for new covered EGUs under this section and shall, by rule, reduce the maximum carbon dioxide
emission rate for new covered EGUs to a
rate which reflects the degree of
emission limitation achievable through the application of the best system of
emission reduction which (taking into account the cost of achieving such
reduction and any nonair quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.
Alarmingly, at current
rates of
reductions in SO2 aerosol
emissions, the «2 degree C limit» will be reached in less than 20

emission reductions using the MSU - EPRI methodology to reduce fertilizer
rate in eligible NCR corn crops is six million metric tons of CO2e per
year.
It could be argued that a society capable of achieving the kind of
rates of
emission reduction in the
year 2100 that are assumed under these pathways would almost certainly be able to convert a static
emissions floor into a decaying one if it were necessary to do so.
The enormous increase in the magnitude of the challenge that has been caused by delay given the limited carbon budget can be seen from a recent statement of Jim Hansen who said that «the required
rate of
emissions reduction would have been about 3.5 % per
year if
reductions had started in 2005 and continued annually thereafter, while the required
rate of
reduction, if commenced in 2020, will be approximately 15 % per
year.
with its highly optimistic assumptions about the future availability of renewables, nuclear, and CCS, the mid-century carbon
emission reduction goal could only be achieved if the annual growth in GDP per capita between now and 2050 were to slow to a
rate of 1 % per
year.
Delaying the peak
year even further to 2020 could necessitate global
emissions reduction rates of up to 9 % per
year — i.e.
reductions on an almost inconceivable scale, entailing technological feats and social sacrifices on a scale comparable to those of the Allied mobilization during the Second World War.26
Even with optimistic assumption about the peak
year for global
emissions and
rates of
emissions reductions thereafter, the best estimate is for warming to reach 4 °C in the 2070s or 2080s, well within the life - spans of children born today.
The entire world will need to peak its ghg
emissions as soon as possible followed by
emissions reductions at extraordinarily ambitious
rates over the next 30
years.
As we have seen above, to stabilize atmospheric concentrations at levels that will avoid dangerous climate change the entire world will need to peak its
emissions in the next few
years followed by
emissions reductions at hard to imagine
rates over the next 30
years.
Would such a solution guarantee a steady
rate of
emissions reductions year after
year?

The difference between Professor Nordhaus's optimal carbon tax policy and a fifty -
year delay policy is insignificant economically or climatologically in view of major uncertainties in (1) future economic growth (including
reductions in carbon
emissions intensity); (2) the physical science (e.g., the climate sensitivity); (3) future positive and negative environmental impacts (e.g., the economic «damage function»); (4) the evaluation of long - term economic costs and benefits (e.g., the discount
rate); and (5) the international political process (e.g., the impact of less than full participation).
