Addressing these challenges will be critical to ensuring that ride-hailing contributes to a more sustainable, equitable, and low-carbon transportation system that is so critically needed. In this blog series, I will tackle just one these challenges – pollution from ride-hailing – and focus on one critical strategy for getting ride-hailing on a lower carbon path – electrified rides.
