First Minister, many cities around the world are striving to become carbon neutral, some by as early as 2025, and this would obviously have a significant impact on air quality. The mayor of Greater Manchester, Andy Burnham, has brought forward their target for carbon neutrality by a decade. We in the Welsh Conservatives have recognised the need for greater ambition here and have called for Cardiff to be the first carbon neutral capital city in the UK. I wonder if you share this type of ambition.
