Abstract

Effects of climate emergency declarations (CEDs) have been reported in multiple cases; this is the first paper to test their potential economic impacts on the market share of electric vehicles (EVs). We use panel data on German CEDs at the district level from 2015 to 2023, employ a difference-in-differences (DiD) approach, and find that compared with districts lacking CEDs, districts with CEDs do not demonstrate significant disparities in EV registrations. We do not find evidence that climate emergencies motivate more environmentally friendly consumption.
