The purpose of UK APIENs (Air Pollution Impacts on Ecosystem Networks) is to monitor and report the negative impacts of air pollution (e.g. acidification, eutrophication, ozone damage or changes in biodiversity) on ecosystems that are representative of freshwater, natural and semi-natural habitats and forests in the UK. It was formed in 2018 by integrating UK national air quality and ecosystem monitoring networks and surveys to meet monitoring (Article 9) and reporting (Article 10) obligations under the EU National Emissions Ceilings Directive (NECD 2016/2284)1 by the UK government. Future reporting will be under the transposed UK NEC Regulations Part 5, aligned to the 4-yearly European reporting cycle.
Two UK reports have been submitted to the European Commission:
First UK Report - this was submitted in 2018 on the UK network of 129 sites and indicators used for monitoring air pollution impacts (Annex V).
Second UK Report - A first submission of monitoring data was made in 2019 from 2017 (or most recently available data, where available) in the UK network was submitted in the NECD Article 9 reporting template to the EC in 2019.
Use of data
- Monitor and provide knowledge on the impacts of air pollution on ecosystems (acidification, eutrophication and ground level ozone damage);
- Assess changes and potential recovery in ecosystem responses to emissions reductions of air pollutants3 under the NECD;
- Contribute to review of critical loads and levels4;
- Contribute to the evaluation of the sufficiency and effectiveness of air pollution abatement policies5,6.
EU National Emissions Ceilings Directive (NECD 2016/2284) Articles 9 and 10.4
The National Emissions Ceilings Directive (NECD 2016/2284) requires Member States to monitor (Article 9) and report (Article 10.4) the negative impacts of air pollution on ecosystems (acidification, eutrophication and ozone damage)2 from national networks that are representative of the Member State’s freshwater, natural and semi-natural habitats and forest ecosystem types.
Annex V of the Directive sets out a list of optional parameters the Member States may use in implementing the obligation. The Directive states that ‘Member States shall report the following information referred to in Article 9 to the European Commission and the European Environment Agency (https://rod.eionet.europa.eu/obligations/767).
- To report by 1 July 2018 and every four years thereafter, to the Commission and the European Environment Agency, the location of the monitoring sites and the associated indicators used for monitoring air pollution impacts (Article 10(4)(a));
- To report by 1 July 2019 and every four years thereafter, to the Commission and the European Environment Agency, the monitoring data referred to in Article 9.
