The report also identifies that if the least efficient 500 TWh of power generation in China's national coal fleet were to be upgraded to the same technology used at Zhoushan Unit 4, this could reduce China's CO2 by about 850 million tonnes each year and it would achieve this reduction at a much lower cost than any other equivalent, scalable,
emission reduction strategy currently available in China.
One interesting component of the SJC decision is its treatment of RGGI: although the Massachusetts DEP had argued that RGGI was a
strategy the Commonwealth is
currently employing as a means to meet its legislated
emissions reductions, the SJC found that because RGGI does not guarantee
emission reductions within the borders of Massachusetts, it can not be counted as a
strategy which would directly lead to decreased
emissions.
