The popularity of sports utility vehicles (SUVs) has hindered the emission benefits of transitioning to battery electric vehicles. This study by Dearman et al. explores the emissions from SUVs, their potential effects on public health and climate goals, and possible solutions. The research employs various scenarios, modeling different rates of SUV sales and electrification. By analyzing carbon dioxide (CO2) and nitrogen oxide (NOx) emissions, as one might expect, the study finds that larger SUVs emit more CO2 and NOx compared to smaller ones. Thus, replacing larger SUVs with smaller ones leads to substantial advantages, including a reduction of 702 million tons of CO2 by 2050 and, at least theoretically, the preservation of 1.8 million life years by cutting down NOx emissions.
