The Zero Emission Zone proposals would see:

• From 2020: Non-zero emission taxis, cars, light commercial vehicles and buses excluded from Queen Street, Cornmarket Street, New Inn Hall Street, Market Street, Ship Street and St Michaels Street
• From 2025: Non-zero emission taxis, cars, light commercial vehicles and buses excluded from roads including New Road, the southern part of Worcester Street, George Street, Magdalen Street, Magdalen Street East, Pembroke Street, Speedwell Street, Norfolk Street and Castle Street
• From 2030: Non-zero emission taxis, cars, light commercial vehicles and buses excluded from all roads within Hollybush Row, Hythe Bridge Street, Worcester Street, Beaumont Street, St Giles, part of Parks Road, South Parks Road, St Cross Road, Longwall Street, Merton Street, Blue Boar Street, St Aldates and Thames Street
• From 2035: All non-zero-emission vehicles, including HGVs, excluded from within the above area

This is a brave proposal. If it goes ahead lets hope others will follow.
