Re “More ambitious rules needed to put zero-emission vehicles on the road“; Commentary, March 8, 2022

Remember high school calculus? The integral of a function represents the area under a curve, which is defined by the integrand, or objective function. In California’s clean car rules, the curve is defined by zero-emission vehicle sales requirements in 2026-35, and the objective is to maximize those sales, minimizing oil use and emissions. 

The California Air Resources Board has proposed requirements that end at 100% ZEV sales in 2035, but start unnecessarily low in 2026 through 2030. David Reichmuth gets it part right in his commentary, calling on the Air Resources Board to increase ZEV sales requirements in 2030, but he and Air Resources Board need to apply their calculus lessons – the optimal solution requires maximizing the area under the curve, which means increasing ZEV sales requirements in 2026 and every year in between.
