The government’s clean air strategy aims to halve harmful emissions by 2025. It plans to ban wood burning stoves and ammonia from farm fertilisers, but abdicates responsibility for vehicle emissions to Local Traffic Authorities. Equality on the roads is the solution. It transforms road safety and efficiency (as I’ve explained to numerous LTAs), it can save the public purse tens of billions, and it more than halves emissions, more or less immediately. How? By eliminating the wasteful stop-idle-restart drive cycle produced by traffic control.
