The Welsh Government has announced a freeze on new road-building while a review of highway schemes across Wales is carried out.  Deputy minister for climate change Lee Waters told the Senedd this week that reaching the goal of net-zero carbon  emissions by 2050 would require a huge effort: ‘In the next 10 years we are going to need to more than double all the cuts we have managed over the last 30 years if we are going to keep temperature rises within safe limits…..Transport makes up some 17 per cent of our total emissions and so must play its part.’  The decision does not appear to favour a Chepstow by-pass unless other measures demonstrably cannot deal with the town’s traffic pollution.
