Our key recommendation is still important and possible: we need to prioritize reducing emissions in the most overburdened areas at a rate that outpaces the emissions reductions from the overall on-road fleet turnover. I'm excited to keep looking ahead and thinking creatively about how to do this 👩💻

One thing that keeps me optimistic: many of these land use and transportation decisions are made locally. We don't necessarily need to rely on the federal government to design transit-oriented and/or sustainable cities that keep traffic away from people 🌃.

We also discussed the importance of paradigm shifts in how we think about mitigating transportation emissions. Land use or transportation policies that can change the spatial patterns of vehicles may be a really important next step for reducing disparities in exposure (more on this soon! 👀).

In our discussion of our article, we praised some of California's great rules and regulations that drove (ha!) this reduction in pollution from cars and trucks. In the last year, these policies (such as Advanced Clean Trucks) have been under attack by the federal government 😞.

Our major finding: air pollution from California's on-road fleet (🚗 🚚) reduced dramatically, but the relative inequality in exposure for people of color and residents of overburdened communities remained nearly constant. While we want everyone to breathe better air, we also want to close the gap!
