Governments should optimize electric vehicle subsidies

Nature Human Behaviour volume 7, pages 470–471 (2023)Cite this article

However, the economically efficient administration of purchase subsidies — a politically, financially and socially advantageous outcome2 — necessitates that three conditions must be met. First, the subsidy should target consumers whose vehicle-purchase decisions change owing to the presence of the subsidy. Second, the subsidized EV should replace a petrol-powered vehicle. Third, the vehicle being replaced should, to the extent possible, be ‘maximally polluting’. The more polluting the replaced vehicle is, the greater the emissions reductions that are potentially realized owing to EV adoption. Emerging evidence raises questions about whether, and to what degree, these conditions are being met.
