Closed petition Increase the speed limit on the M4 back to 70mph

The reduced limit is causing congestion and has an impact on drive time. It increases the time a car is located in an area producing the same level of carbon emissions a standard same volume per second over time. A faster speed would therefore allow a higher gear producing fewer emissions and spending less time in the area therefore reducing the emissions.
