The World Health Organisation recently revealed that 90% of the world's children are living in areas with illegal air pollution*. I know you have made protecting children from air pollution a priority for your Mayoralty, are your initiatives on track? How will you be monitoring the impact of your air quality improvement schemes, particularly where children are likely to be most affected?

It is not acceptable that children anywhere in the world are exposed to air pollution which damages their lungs, shortens their lives and limits their potential. It is shocking that a new study published in the Lancet has revealed that children in London are exposed to diesel-dominated air pollution which results in them having approximately 5 per cent less lung capacity.

This is why I am determined to act. I have already introduced the Toxicity charge in central London, delivered seven Low Emission Bus Zones and stopped licensing new diesel taxis. But we need to go further which is why I am introducing the Ultra Low Emission Zone in central London in April 2019 and then will expand it up to the North/South circular in October 2021. I will also apply the ULEZ standards to buses, coaches and lorries across the whole of London.

These efforts are already delivering results, with around an 8% reduction in nitrogen dioxide concentrations in central London since October 2017 when the T-charge began.

To further monitor the impact of these measures I will be using the existing London Air Quality monitoring Network (LAQN) and the London Atmospheric Emissions Inventory (LAEI). Working with C40 I am piloting a new innovative hyper-local monitoring sensor system, combining static, mobile and wearable air quality sensors, to increase the number of locations where we directly monitor air quality, including at schools.
