“PRANA” – Portal for Regulation of Air-Pollution in Non-Attainment cities, is a portal for managing and monitoring the implementation of the National Clean Air Programme (NCAP). It supports tracking the physical as well as financial status of city air action plan implementation and disseminates information on air quality management efforts under NCAP to the public.Information related to various ac...

The publication describes the preliminary status of German air quality in 2020. Regarding PM (particulate matter) the reduction of pollution has continued. Consistently to this development, there are hardly any exceedances of the EU annul limit value for nitrogen dioxide (NO2). And there was less ozone pollution than in both previous years. The second part of the reports deals with the influence o...

In 2024, the ecological and environmental quality continued to improve in China with the environmental security situation remaining stable. Rate of public satisfaction with the ecological environment exceeded 90% for four consecutive years. However, the gains in ecological and environmental quality improvement are not yet firmly established, making further improvement increasingly challenging.Ambi...

Due to their small size and ability to penetrate deeply into the respiratory system, ultrafine particles (UFP) pose a significant health risk. Their concentrations and sources are not consistently monitored and regulated in urban areas, including Paris. This study aims at presenting an overview of UFP measurements carried out in Paris from October 2019 to December 2022 using a mobility particle si...

Airparif carried out a first-of-its-kind monitoring campaign for ultrafine particles (UFPs) at several monitoring sites located at and around Paris-Charles de Gaulle Airport in autumn 2022, in partnership with Groupe ADP. These solid particles, suspended in the air, have a diameter of less than 100 nanometres (nm) (smaller than a virus). These air pollutants are not currently regulated, but are th...

Airparif (the independent air quality observatory for the Greater Paris area) has established an open-data portal, which provides downloadable datasets and APIs with raw and validated air quality data, including pollutant concentrations by monitoring station (e.g., NO₂, PM₁₀, PM₂.₅, O₃), emissions, exposure indicators, air quality indexes, pollution episodes, mapped concentrations, and historical ...

The document discusses South Korea's co-creation initiative aimed at combating fine dust pollution through a collaborative approach involving government, civil organizations, and research institutes. The initiative includes the establishment of the PM Center to develop technologies and policies for fine dust reduction, supported by significant funding and a structured partnership among various sta...

Like all industrialised cities, Adelaide and South Australian regional centres are confronted with managing or remediating historical site contamination. The scope of the community engagement plan should be directly proportionate to the size and nature of the extent of the contamination. The South Australian Environment Protection Authority (EPA) expects that the person who has liability for site ...

Air Quality Index (AQI) is information about atmospheric pollutants, which is essential for governments to inform the public about the current air quality and potential health risks. By analyzing the AQIs from 11 countries (regions), authors discovered considerable variations in the design of AQI information, which may open up room for unintended interpretation from the public. Therefore, as an at...

The UNEP Governing Council adopted the Bali Guidelines in 2010 to assist countries in filling gaps in national and sub-national legislation to facilitate broad access to information, public participation and access to justice in environmental matters. In 2012, UNEP and the United Nations Institute for Training and Research (UNITAR) joined hands to promote the Bali Guidelines, including through a p...
