摘要：	It is easy to argue that the transportation field will see more changes in the next 10 years than we have seen in the past 80 years. The innovations leading these changes include automated and connected vehicle technology and electric vehicles technology. One of the motivating factors behind the adoption of these technologies is that many governments and firms have made pledges to reduce greenhouse gas emissions (GHG) over the next decades (NASEM 2021a). These commitments reflect the scientific consensus that increasing GHG concentrations in the atmosphere are causing climate change, which is characterized by rising average global temperatures and increasing extreme weather events. Economic and social costs from climate change are already apparent with rising sea level and droughts. Net zero GHG emissions is often cited as a goal to halt these climate change effects. Net zero emissions means the amount of greenhouse gas produced and the amount removed from the atmosphere through carbon capture and sequestration are equal. Because carbon dioxide (CO_2) is the largest GHG emission, net zero goals are often termed deep decarbonization. In 2019, the transportation sector was the largest source of GHG emissions in the United States at 29%, with the vast majority CO_2 with much smaller amounts of methane (CH_4), nitrous oxide (N_2), and hydro-fluorocarbons (HFC) (EPA 2022).
