Air pollution has fallen significantly since 2010, and our recently published environmental improvement plan sets out the actions that we will continue to take to continue to improve air quality. They include additional measures to tackle domestic burning and agricultural emissions, continued delivery of the £883 million NOx programme and supporting local authorities to improve air quality more quickly with clear guidance and tools.

We want to increase the recycling of packaging material, food and other recyclable material in the ‘non-household’ municipal sector, which includes businesses, public organisations (e.g. schools, universities, hospitals and government buildings) and other organisations. This will help us to increase the amount of material that we recycle and reduce the amount of waste that we send to landfill.

Following support in response to initial consultation, the Environment Act 2021 stipulates that all businesses will be required to arrange for the collection of a core set of materials (glass; paper and card; plastic; metal; and food waste) for recycling in England

In 2021 we published a second consultation on recycling consistency. This consultation sought views on increasing consistency in recycling, including on the materials in scope of collection; exemptions; statutory guidance for waste collectors and cost reduction options for micro firms.

We are finalising our policy positions and analysis for impact assessment – we aim to publish the consultation response soon.

The Government recognises that short-term exposure to elevated levels of PM2.5 can impact health, particularly for vulnerable groups. This is why we provide alerts and advice during air pollution episodes to ensure people can access the information and health advice they need in order to minimise impacts. We are also taking action to increase public awareness about air pollution, including through an expanded £8 million funding pot which will be made available to local authorities through the Air Quality Grant scheme.

Under the Environment Bill, the Government will have a duty to bring forward a target for PM2.5 by October 2022. In setting our air quality targets, we have sought advice from the Committee on the Medical Effects of Air Pollutants (COMEAP) on whether the priority aim should be long-term exposure rather than short-term. COMEAP advised that a focus on long-term average concentrations of PM2.5 is most appropriate to deliver public health benefits. This advice has been published and can be accessed via this link: https://www.gov.uk/government/publications/fine-particulate-air-pollution-pm25-setting-targets.

The two air quality targets that we plan to set will focus on reducing the long-term exposure to PM2.5 and its associated health impacts, actions taken to achieve these targets will contribute to reducing average daily concentrations of PM2.5.

In England, all large incinerators, also known as energy from waste (EfW) plants, are regulated by the Environment Agency (EA) and must comply with strict emission limits set by the Industrial Emissions Directive (as amended under the EU Withdrawal Act 2018). Permits are not issued if the proposed plant will have unacceptable impacts on human health or the environment.

Emission limits within permits are set for total particulate matter (TPM), which includes both PM10 and PM2.5. New permit applications are assessed to ensure that impacts from both types of particulate matter will be acceptable by assuming worst-case scenarios, whereby TPM is made up entirely of either PM10 or PM2.5. This allows the EA to determine the potential impact from each of these pollutants were they to make up the entirety of the TPM emitted. This is a precautionary approach as in practice TPM will be a mixture of sizes, and so the true impact will be less. The EA has not carried out a formal assessment with regards to setting limits for emissions of PM10 and PM2.5 individually because the TPM approach delivers effective control of both PM10 and PM2.5 emissions.

The EA takes into account the existing concentration of particulate matter in the areas surrounding EfW plants when setting TPM emission limits. The EA assesses new EfW plant permit applications using air quality modelling to predict the worst-case scenario for the concentration of particulates arising from the plant for both PM10 and PM2.5. This concentration is then added to the existing (background) concentration to determine the total predicted environmental concentration, which is then compared against the relevant air quality standard. If impacts from the EfW plant could cause an air quality standard to be exceeded, then a lower limit for total particulate matter could be specified in the permit, or the permit may be refused.

Finally, on the potential merits of live emissions data monitoring for EfW plants; all EfW plants in England are already required to continuously monitor emissions of oxides of nitrogen, total particulate matter, carbon monoxide, total organic carbon, sulphur dioxide and hydrogen chloride. Some are also required to continuously monitor ammonia.

Operators are required to report the results from monitoring to the EA every 3 months, and to submit annual reports of their emissions to the EA’s Pollution Inventory. The EA also carries out regular inspections and audits to ensure plants comply with their permits.

Our Clean Air Strategy, published in 2019, set out the comprehensive action required across all parts of Government and society to reduce our emissions of five key pollutants, including particulates, to meet legally binding targets for 2020 and 2030.

We are taking action now to deliver these commitments. For example, we recently passed legislation to phase out the sale of house coal and small volumes of wet wood for domestic burning across England – measures focused on tackling a key source of PM_2.5.

Our landmark Environment Bill delivers key parts of the Strategy. It introduces a duty to set a legally binding target for fine particulate matter, in addition to a further long-term air quality target. In August, Government published a policy paper on environmental targets which outlined our objectives for air quality targets – to reduce the annual mean level of PM_2.5 in ambient air and reduce population exposure to PM_2.5 in the long-term.

Emissions from incinerators in England are regulated by the Environment Agency under environmental permits. Permits contain limits for total particulate matter (TPM) which includes particulates of all sizes, including PM_2.5. All incinerator permits issued since 3 December 2019 have contained a lower daily average TPM limit of 5 mg/Nm³ (compared with permits issued before then for which the limit was 10 mg/Nm³). Permits for incinerators issued before 3 December 2019 will be changed to require compliance with the lower 5 mg/Nm³ limit by 3 December 2023. Operators must continuously monitor their TPM emissions and the Environment Agency carries out regular inspections and audits to ensure that plants are complying with their permits.
