Best available techniques (BATs) have emerged as a key policy tool to prevent and control the emission of industrial pollutants, and thereby to ensure the protection of human health and the environment. Applying BATs to different sources is a key requirement for Parties to the latest three…
Sound emission inventories are the first step for designing effective clean air policies as they provide information about the main sources and the most acute air pollution problems in a country.
Under the Convention on Long-range Transboundary Air Pollution (Air Convention), UNECE has therefore…
While nitrogen is vital for plant growth, 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…
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…
Mapping air pollutant emission sources in a country helps experts and decision-makers identify the most effective policies. Understanding the regional distribution of emissions is crucial for effective policy implementation.
Spatially allocating—or gridding—emissions is technically challenging.…
Representatives from countries across Central Asia and experts on the climate and clean air came together in Astana, Kazakhstan this week (11-13 June 2024) for the Sub-Regional Workshop on Integrated Planning for Climate and Air organized by the UNEP-convened Climate and Clean Air Coalition (CCAC)…
In a ground-breaking decision in December 2023, Parties to the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention) agreed to revise the Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone, as amended in 2012 (Gothenburg Protocol), which is expected to…
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…
Ecosystems are highly sensitive to air pollution. To sharpen emissions reductions measures under the UNECE Convention on Long-Range Transboundary Air Pollution, expert groups have started scientific and technical work to support decision-making in the context of the process to revise the Protocol…
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…
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…
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,…
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 –…
The impact of different air pollutants on vegetation and crops has been studied for over 35 years in the framework of the UNECE Convention on Long-range Transboundary Air Pollution, through its International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops (ICP…
Policy solutions for pressing problems like air pollution require sound data. Emission inventories can help in determining the major sources of air pollution in a given country.
As a result of integrated air pollution management strategies developed under the UNECE Convention on Long-range…
Understanding how pollutant emissions will evolve in the future is essential for designing effective clean air policies today while taking into account the available resources in a given country.
While air quality in the UNECE region has improved over the past few decades as a result of…
Sound emission inventories are the first step for designing effective clean air policies as they provide information about the main sources and the most acute air pollution problems in a country.
Under the Convention on Long-range Transboundary Air Pollution (Air Convention), UNECE has therefore…
Taking up some of the main results of the recent review report, which assessed the effectiveness of the amended Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone (Gothenburg Protocol) under the UNECE Convention on Long-range Transboundary Air Pollution, experts discussed…
Breathing clean air is a necessity for everyone and decent air quality is a shared responsibility that can only be achieved if we work together. This is what Member States in the UNECE region realized 45 years ago, when they started negotiating the first multilateral, legally binding treaty to cut…
To address the conclusions of the review of the amended Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone (Gothenburg Protocol), as adopted by the Executive Body to the UNECE Convention on Long-range Transboundary Air Pollution in December 2022, further work is currently being…
Research on and monitoring of the effects of air pollution on different environmental media and health has been carried out for more than four decades under the UNECE Convention on Long-range Transboundary Air Pollution. The data and research that has emerged from these efforts is unique as it…
The massive use of fertilizers and the production and use of manure in agriculture over the past 100 years have led to significant reactive nitrogen emissions to air and releases to water and land. Burning of fossil fuels (in vehicles, power plants and industry) is another source of reactive…
A recent study published in The Lancet found that almost the whole world's population was exposed to unsafe levels of air pollution in 2019, with only a mere 0.001 percent breathing air that contains fine particulate matter (PM2.5) at concentrations lower than what the World Health Organization…
What are emission inventories and what purpose do they serve? Why is it important to develop emission inventories? If you don’t know the answer to these questions, you might be interested in taking the e-learning course on How to report emissions under the Convention on Long-range Transboundary Air…
While the impacts of air pollution on vegetation and crops are sometimes overlooked, they can take a high toll on food production. As the food and energy crises have recently shown the vulnerability of our food systems, the impacts of air pollution on agricultural yields and food production should…
