As guests of the planet, we human beings can thrive only if our host environment is thriving. We are strongly connected to it, more than we probably understand and more than we probably dare to admit.
Conversely, the ways humans treat the environment has clear negative effects on our health and…
Millions of people are experiencing the severe impacts of climate change, through unprecedented extreme weather episodes and more frequent disasters. According to the Chair of the Intergovernmental Panel on Climate Change, Hoesung Lee, its latest report, released last week, “is a dire warning about…
Minerals such as lithium, cobalt, and copper are essential for digitalization, for renewable energy technologies, and for the further deployment of electric vehicles. Demand for these and other minerals – known as “critical raw materials” (CRMs) – is growing fast as governments and businesses act…
Today marks the holding of the first meeting of the Working Group on Tailings Safety and the Prevention of Accidental Water Pollution (IIWG) in Kazakhstan – the first comprehensive dialogue on these issues between all relevant stakeholders and national authorities in the country.
After being…
“Countries need to take concrete actions to prevent, prepare for and respond to industrial accidents and reduce the risks of related technological disasters. The UNECE Convention on the Transboundary Effects of Industrial Accidents and the tools developed for its implementation provide a means to…
The COVID-19 pandemic and the lockdowns it triggered have affected mobility patterns in most countries and brought to the fore many issues that had not received enough policy attention until now.
For instance, the fear of the virus and the search for social distancing led to a historic decline in…
From the Sandoz chemical spill of 1986 in Schweizerhalle, Switzerland, to the rupture of a dam storing mine tailings containing cyanide in Baia Mare, Romania, 2000; and last year in Beirut, the explosion of ammonium nitrate stored in warehouse near residential areas, what these chemical and…
COP26 was a positive step forward in the fight against climate change, but as the UN Secretary General pointed out in his comments: “it is not enough. We must accelerate climate action to keep alive the goal of limiting the global temperature rise to 1.5 degrees.” The compromise deal reflects the…
Over the last two weeks at COP 26, governments, the private sector and a wide range of actors have unveiled plans for climate action in crucial areas ranging from methane, to forests, finance, fashion, transport and far beyond. As US Special Presidential Envoy for Climate John Kerry put it in our…
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 –…
This year, the UNECE region has seen devastating impacts of climate change and multiple natural disasters, such as the floods in Belgium, the Netherlands and Germany. Disasters caused by natural hazards, on the rise due to climate change, can also trigger technological accidents.
On today’s…
Policymakers looking for innovative solutions to global problems are increasingly recognizing that the answers have been around for a long time even before the earth got populated by humans. Trees can help achieve pressing global objectives for sustainable development, biodiversity conservation,…
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…

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…
