Yes, scrappage programs are critically important. The reason is that only 6% to 7% of vehicles on the road in a year are new. In fact, 35% are 12 years or older with higher GHG emissions. While it's great to focus on ZEV adoptions through things like incentives, ZEVs right now are only 3.2% of new vehicle purchases, amounting to 0.2% of the total fleet. If the government wants to have an impact on fleet-wide emissions, the only way to do that is to put in place a scrappage program that actually makes the overall fleet of millions of vehicles more efficient. That can include both ZEVs and ICE vehicles.
