That's a really good question. What we need to do is make it a political priority, because if it is a climate change emergency with this Government, then make it a priority. How much money was spent on the M4, for example? £115 million. I could stand here and list waste after waste after waste. Opportunity lost after opportunity lost. When you don't want to do something, saying there's not the money is always an excuse. What we should be doing is investing in clean transport. If we accept that it is an emergency then we really have to do something now and not just talk about it. Diolch yn fawr.
