A map of 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 progress of the 2030 Agenda for Sustainable development hinges on the availability of natural resources and a transition to sustainable means of their production and use. Minerals and petroleum provide the raw materials needed for the economy. While a low-carbon economy requires a wide variety …
Realization of the Sustainable Development Goals will require massive inputs of low-carbon energy, critical raw materials, and other natural resources, including land and water. These demands are aggravated by rapid urbanization of the world’s population, which stresses grid-based power,…
Sustainable development depends on optimal and responsible production and use of natural resources. Today's resource patterns are unsustainable in terms of their environmental and societal impact and ensuring resource availability now and in the future. Developments in sustainable resource…
In a joint statement, the Executive Secretaries of the United Nations Regional Commissions have called for enhanced regional cooperation to develop nature-based and technological solutions for capturing CO2 emissions from the atmosphere and ensuring its long-term storage. Version française

With the review of the amended Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone (Gothenburg Protocol) well underway, expert groups under the UNECE Air Convention are now collecting information to assess the effectiveness of measures.
The amended Protocol establishes legally…
With the UN Food Systems Summit taking place next week under the auspices of the UN General Assembly (23 September 2021), we must recognize that the food systems we have built over recent decades are unsustainable. The food choices we make every day as consumers and producers of food are having a…
August is wildfire season in many parts of the Northern Hemisphere. Many areas in the UNECE region, including North America, Siberia, and Mediterranean countries have experienced unusually hot and dry weather this year, and with that some of the biggest wildfires on record. Areas burned in Turkey…
By Ms. Olga Algayerova, UN Under-Secretary-General and Executive Secretary of UNECE, and Ms. Elisabete Quintas da Silva, Head of Department, Sustainable and Efficient Use of Resources Operational Programme, Government of Portugal, and Chair of the UNECE Committee on Environmental Policy.

Four decades of experience under the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention) have demonstrated that ratification and implementation of the Convention and its protocols reduces health and environmental impacts in a more cost-effective way than unilateral action by…
Transport continues to be a significant source of air pollution, especially in cities in the UNECE region. Air pollutants, such as particulate matter (PM) and nitrogen dioxide (NO2), harm human health and the environment. Although air pollution from transport has decreased in the last decade…
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…
Over the past 100 years, humans have massively altered flows of nitrogen on our planet. While this has increased food production, it has led to and multiple threats to our health and risks irreversible and abrupt environmental change if decisive action is not taken.
Driven by intensive animal…
The importance of statistical information to help us cope with disasters has never been clearer than over the past year. As the Covid-19 pandemic has gripped the world, numbers have become our bread and butter. Yet the pandemic has also highlighted the challenges and imperfections in many systems; …
Contrary to what most people think, transport is not the major source of particle pollution in the air. In fact, in Serbia and many other countries, domestic heating is the most important source of harmful particle pollution (PM2.5 and PM 10). In Serbia, pollution is a result of heating, which is…
Black carbon (BC) is an air pollutant with significant impacts on our health and climate. Resulting from incomplete combustion processes, it is part of fine particulate pollution (PM2.5) and estimated to have a warming impact on climate that is 460–1,500 times greater than that of carbon dioxide (…
Mobility is a primary enabler of our economic and social life. However, despite its many benefits, the costs of mobility to societies around the world remain unacceptably high. These include greenhouse gas emissions (transport accounts for some 24% of global CO2 emissions, three quarters of which…
When scientists in the 1960s investigated the causes of the die-back of forests, the so-called ‘Waldsterben’, and acidification of lakes with associated fish loss, they found that air pollution, often emitted thousands of kilometres away, was the culprit. This research formed the basis for the…
Progress in reducing emissions of key air pollutants has been uneven across the UNECE region over the past few decades. To create a level playing field across the region, the Protocol to Abate Acidification, Eutrophication and Ground-level Ozone (Gothenburg Protocol), a unique instrument to reduce…
Air Convention Task Force discusses impacts of COVID-19 lockdowns on air quality in the UNECE region
One year after the first COVID-19 lockdown in many parts of the UNECE region, scientists and experts are studying the effects of lockdown measures on air quality. A study from Germany showed that while levels of nitrogen oxides (NO2) measured at urban stations decreased during the lockdown in…
The extraction of raw materials worldwide has more than doubled since 1990 and could double again by 2060 in the absence of corrective policies. According to the UN International Resources Panel, resource extraction and processing account for 90% of global biodiversity loss and water stress impacts…
UNECE continues to help its member States to respond to COVID-19 crisis. As part of this work, Guidelines and Best Practices for Micro-, Small and Medium Enterprises in Delivering Energy-Efficient Products and in Providing Renewable Energy Equipment developed earlier are being customized for North…
Buildings consume over 70 per cent of the electrical power generated and 40 per cent of primary energy and are responsible for 40 per cent of carbon dioxide emissions from related fuel combustion. At the same time, in 2018, out of 4.5 trillion USD spent on building construction and renovation, the…
Systemic deficiencies with regard to access to information, decision-making or compliance with environmental law can seriously threaten successful implementation of circular and green economy and sustainable development. Taking a case to court to advance a widely shared public interest remains an…
