The Caucasus and Central Asia accounts for over 30 million hectares of forests and wooded lands, an area approximately the size of Italy Forest landscape restoration in this area is critical for supporting livelihoods and local economies, preventing soil erosion and desertification, enhancing…
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…
The COVID-19 pandemic has brought about immense changes in how people move around the world. International travel ground almost to a halt at the onset of the crisis, as restrictions were imposed and borders closed. Internal migration, too, was restricted in many countries as lockdowns were declared…
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 –…
The COVID-19 pandemic has exposed the world’s fragilities, including the weaknesses of our food systems which exacerbate hunger, obesity, poverty, political instabilities and economic crises. To overcome common and regional challenges, the five UN regional commissions have been working jointly on…
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…
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…
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 (…
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…
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…
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 transboundary rivers, lakes and aquifers, accounting for 60 per cent of global freshwater flows, are of crucial importance for the sustainable development and political stability of riparian States, the financial means for their management, development and protection are insufficient in most…
Knowing where exactly air pollutant emissions are coming from in a given country is important to make viable policy decisions.
As a result of integrated air pollution management strategies developed under the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention…
Risk is a part of our everyday lives. When we wear a helmet to ride a bike, for example, we accept a small inconvenience to reduce the risk of a fall or an accident. When a homeowner decides to retrofit their house, they incur a cost to shield against an earthquake or a flood. Faced with the COVID…
Every year we lose about 14% of the food produced before it is sold, and this does not even include the food never harvested. Even more is wasted at retail and consumer levels. At the same time, over 800 million people worldwide suffer from hunger, while food loss is a major contributor to CO2…
