It is for this social goal (as well as the free money EPA will give to ignorant consumers who can't calculate fuel savings on their own) that justifies — again, according to EPA's own numbers —
imposing aggregate costs on vehicle buyers of $ 36 billion in the year 2030 alone (to pick just one year's figure).
Apart from the pointless and potentially large time
cost imposed by this refusal, the task of
aggregating PCMDI data with which we are unfamiliar would create the risk of introducing irrelevant collation errors or mismatched averaging steps, leading to superfluous controversy should our results not replicate theirs.
