Are regulators focusing an excessive amount of on EV gross sales and never sufficient on retiring ICE autos?


International EV gross sales are steadily growing with assist from regulators, however that will not matter if current gasoline and diesel autos aren’t retired rapidly, new analysis argues.

“The sluggish pace of fleet turnover presents a considerable barrier to deep decarbonization,” researchers state in a new guide on vitality transition (through Axios).

Researchers in contrast emissions insurance policies, like the UK’s plan to finish gross sales of latest gasoline and diesel automobiles in 2030, with common automobile lifespans. They discovered important “turnover lag” between the beginning of latest rules and the retirement of internal-combustion autos. 

So attaining emissions reductions important sufficient to restrict local weather change would require “each quickly phasing out emitting automobile gross sales and considerably accelerating fleet turnover,” Emil Dimanchev, one of many guide’s authors, defined in a Twitter thread detailing the thesis.

To restrict world warming to 1.5 levels Celsius—a aim in step with the Paris Local weather Accord—gross sales of internal-combustion autos must begin phasing out in 2025, however the lifespan of these autos would additionally must be decreased from 16 years (the present common in the US) to 9 years, Dimanchev argues.

This reiterates that, due to sluggish fleet turnover charges, the shift to EVs will take awhile with out coverage intervention. It additionally raises numerous questions.

Ought to automakers give their present gasoline and diesel automobiles shorter lifespans, making certain they do not final past an anticipated transition to EVs? Whereas that ensures the fleet will flip over extra rapidly, it additionally implies a number of waste. It could virtually be a throwback to the heyday of auto trade deliberate obsolesce within the Fifties, when shoppers had been inspired to commerce of their automobiles yearly in step with styling modifications.

This additionally begs the query of whether or not incentives ought to concentrate on retiring internal-combustion autos moderately than shopping for new EVs. It would not be unprecedented; 2009’s “Money for Clunkers” program pressured the retirement of older automobiles constructed to less-strict emissions guidelines.

A brand new program particularly concentrating on gasoline “superusers” is perhaps a great place to start out. California has had a “gross polluter” retirement program, which maybe could possibly be retooled and expanded. The state needs to finish gross sales of latest internal-combustion autos by 2035. Ought to current gasoline automobiles be coaxed into retirement earlier than that?
