Study: Cash-for-Clunkers Programs Should Use Fuel Economy Rather Than Age to Maximize GHG Reductions

Green Car Congress

A study by researchers at UC Davis suggests that a properly designed vehicle scrappage (i.e., Cash for Clunkers”) program could maximize greenhouse gas emissions savings by using fuel-economy based eligibility requirements rather than age-based requirements. Allan et al.

We Need A Cash For Stinkers Program 

CleanTechnica EVs

Just like the Cash for Clunkers program during the financial crisis, a “Cash for Stinkers” program is needed to battle the climate crisis. Cash for Clunkers was designed to increase new car sales and, in the meantime, put more fuel-efficient vehicles on the road.

The data revealed multiple trends that correlate with a decrease in overall fuel economy and efficiency. It’s not likely that people are actually thinking about fuel economy that way, that they can splurge on a less fuel efficient vehicle. It is more likely utility-based in some way, but it is correlated with fuel economy nonetheless.

Proposed scrappage scheme meets criticism

Green Cars News

An article in the New York Times criticised the so-called “cash for clunkers&# legislation that would give people vouchers worth as much as $4,500 to replace old cars with new ones. It suggests that the House’s programme seems as though it is designed to undercut both its economic and environmental value.

Empirical results also revealed that even if the fuel economy of less fuel-efficient ordinary passenger vehicles were improved to levels comparable with those of the best available technology, i.e. hybrid passenger cars currently being produced in Japan, total CO 2 emissions would decrease by only 0.2%.
