Thank you, Minister. Earlier in the year, Cardiff Bus and Stagecoach announced that it was retrofitting 49 of its most polluting buses with exhaust clean-up technology, to reduce their nitrogen oxide emissions by 97 per cent, thanks to funding from the Welsh Government. However, in England, they are now one step ahead and have started to introduce air-filtering devices, which can remove as much as 65g of pollutants from the air over a 100-day period, which equates to the cleaning of 3.5 million cubic litres of air—enough to fill 1,288 Olympic-sized swimming pools, I'm led to believe. This has been rolled out in cities such as Manchester, Newcastle and Southampton, and I'm keen to know if the Welsh Government will commit to funding similar initiatives in Wales.
