Air Pollution Convention

UNECE Task Force advises caution on use of low-cost sensors to monitor air pollution

The technology associated with low-cost sensors (LCS) to monitor air quality has seen rapid developments over the past few years. While their use becomes more widespread and some are promoting them as silver bullet for air pollution science and control, experts have advised caution.  

It is clear that LCS have a number of benefits, as they render air pollution monitoring less expensive compared to reference instruments thereby allowing their deployment in larger numbers and in remote locations or in places with no other access to monitoring.  

UNECE Air Convention experts to model wildfire impacts on air pollution

As the climate warms, wildfires are becoming more frequent. Parts of Southern Europe, such as Spain and Greece, have already seen their first wildfires of the season, with devastating impacts on local ecosystems and biodiversity. Wildfires, however, also have major impacts on global and regional atmospheric chemistry, climate, and air quality and health. Emissions of air pollutants and greenhouse gases, and their long-distance transport can also impact people and ecosystems further away.

Launch of a partnership for Clean Air in Georgia

Air pollution levels in Georgia are considered unhealthy with annual average of fine particles PM2.5 exceeding the World Health Organization's air quality guideline by at least three times. 

To support Georgia in further improving its air quality management system, a new EU-funded project, entitled ‘Air Quality for Better Citizen’s Health’ was launched on 19 April.  

Air quality modelling advances to support revision of the Gothenburg Protocol

Following the decision of Parties to the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention) to revise the Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone (Gothenburg Protocol), which is expected to further strengthen efforts to reduce air pollution in Europe and North America, technical and scientific work has begun to support the revision process.   

UNECE facilitates air pollutant emission maps to support clean air policies in Georgia

Mapping air pollutant emission sources of a given country can help experts and decision-makers understand which policies are most viable. Spatial allocations of emissions are also important to understand where emissions are coming from on a regional level. 

Spatially allocating – or gridding – emissions is technically complex. It requires applying the gridding matrix to the inventory emissions to transform source-based inventory emissions to gridded emissions.  

UN Environment Assembly highlights rising global role of UNECE Multilateral Environmental Agreements to address triple planetary crisis   

Faced with increasing impacts of climate change, pollution and biodiversity loss, which together constitute the “triple planetary crisis”, no country can act alone. Like nature itself, these challenges know no borders, which makes international cooperation a crucial part of action to address them.  

Executive Secretary to highlight global relevance of UNECE Multilateral Environmental Agreements at UN Environment Assembly

Multilateral Environmental Agreements (MEAs) will be at the forefront of discussions at the sixth session of the United Nations Environment Assembly (UNEA-6) on how to tackle the triple planetary crisis. 

Executive Secretary Tatiana Molcean will lead a UNECE delegation to UNEA-6, the world’s highest decision-making body on the environment, which takes place from 26 February to 1 March at the United Nations Environment Programme (UNEP) headquarters in Nairobi, Kenya. 

Scientists provide recipe to halve Nitrogen pollution from food production

Nitrogen, which is vital for plant growth, is present in animal excreta and synthetic fertilisers that are applied to land to boost crop production. But excessive and inefficient use of this nutrient means up to 80% of it leaks into the environment, mostly in various polluting forms of nitrogen: ammonia and nitrogen oxides, which are harmful air pollutants; nitrous oxide, a potent greenhouse gas; and nitrate, which affects water quality.
