This week on Talking Headways we're joined by Member of the Welsh Senedd (Parliament) Lee Waters and Dr. Jennifer Kent of The University of Sydney. They talk about how Wales set climate targets, did a roads review, got to a 20 mile per hour speed limit across the country, and what it might take for other places to do the same. They share the importance of leadership, the data around benefits related to 20mph, and how waiting to long for change might doom it.
