Hello IMLA/Climate Group, I hope all is well. I'm writing to share with you a draft paper <https://climate.law.columbia.edu/sites/default/files/content/Legal%20Tools%20for%20Achieving%20Low%20Traffic%20Zones%20(LTZs)%20LEZ%20ULEZ%20Congestion%20Pricing%20in%20the%20US%20Law%20Context.pdf> I've written on congestion pricing and low emissions zones (together I'm calling them "Low Traffic Zones" or "LTZs") in the U.S. law context (if you don't want to wade through the whole thing, a summary blog post <http://blogs.law.columbia.edu/climatechange/2020/02/10/legal-tools-for-achieving-low-traffic-zones-ltzs-new-sabin-center-white-paper/> is here). The final version will be published in the Environmental Law Reporter in April. I hope you find it helpful, and I'd be happy to continue the discussion about this sometime soon. Have a great weekend!
