Looking at the environmental impact assessment of the combustion engine, both diesel and petrol, I wonder what environmental impact assessment has been done on the air quality in school playgrounds, because I had a visit today from St Teilo’s Church in Wales High School, where I’m also a governor, and that is one of the schools identified by ClientEarth as one of 1,000 schools across the UK that is suffering from really damaging levels of air pollution because of their proximity to roads. I just wondered how many of these nearly 1,000 schools are in Wales.
