Thank you for contacting me about air quality.

It is encouraging that air pollution has reduced significantly since 2010. Emissions of nitrogen oxides have fallen by 33 per cent and are at their lowest level since records began, however, there is still more to do. 

The Government has put in place a £3.8 billion plan to improve air quality and create cleaner transport. This includes nearly a £1.5 billion investment to support the uptake of ultra-low emissions vehicles; £1.2 billion to increase cycling and walking and make our roads safer for vulnerable users; and £880 million to help local authorities develop and implement local air quality plans and to support those impacted by these plans. This funding is in addition to a further £2.5 billion to support a number of cities improve their local transport systems through the Transforming Cities Fund.

The Chancellor announced at the Budget last March a £304 million investment in capital over the next two years to combat roadside pollution, enabling local authorities to take steps to reduce nitrogen dioxide emissions.

You may be aware that the Government’s Clean Air Strategy aims to cut air pollution and save lives, backed up by new primary legislation. The Strategy details how the UK will go further and faster than the EU in reducing exposure to particulate matter pollution. It sets out a goal to halve the number of people living in locations with concentrations of particulate matter above WHO guidelines and I am encouraged that it has been described by the WHO as 'an example for the rest of the world to follow'.

The Environment Bill builds on this Strategy and sets an ambitious, legally binding target to reduce fine particulate matter, and increase local powers to address sources of air pollution. This target will be among the most ambitious in the world and improve the quality of millions of people’s lives. 

The Government is committed to taking action on PM 2.5, as it is the pollutant that has the most significant impact on health. Ministers are developing a clear evidence-based process for setting the fine particulate matter (PM 2.5) target introduced in the Environment Bill. This process will involve thorough analysis and independent expert advice, considering economic, social and technological factors. It will also involve detailed analysis to assess what additional action would be needed to achieve potential targets. Both Parliament and the public will have the opportunity to provide input to the development of an ambitious and achievable target.

Thank you again for taking the time to contact me.
