Sources of NOx emissions, Southern California, 2020. Mobile - On-Road is the largest source about 2/5ths, with Mobile - Off-road is about 1/5, Locomotives are about 1/8th, and everything else is about 1/4
Happy #CleanAirDay! The Inland Empire has the US's dirtiest air, and LA is not far behind. The top source of ozone precursors is cars and trucks. Let's get dirty cars and trucks off the road by electrifying freight and passenger rail!
A reminder from #LACounty's Chief Sustainabilty Office:
@metrolosangeles.bsky.social is celebrating California #CleanAirDay today by offering FREE RIDES, no ticket required.
Every ride helps reduce traffic and improve Southern California’s air quality!
That’s why CARB follows data—not politics.
This #CleanAirDay we are reminded why we can’t slow down. Even with federal attacks on proven science, CARB is pushing forward with bold strategies to keep CA’s air safe for all.
Take the pledge ➡️ www.cleanairday.org/pledge/
