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…
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…
Transboundary waters are a global common good crucial for human life, which require concerted management and protection. The ninth session of the Meeting of the Parties (MOP 9) to the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) has…
Approximately 40% of the world’s population live in transboundary river and lake basins, accounting for an estimated 60% of global freshwater flow. These shared water resources support the livelihoods of more than 3 billion people. In a world increasingly impacted by the effects of climate change,…
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…
The new UNECE Guide on producing CPI under lockdown, published today, helps national statistical offices to produce the Consumer Price index (CPI) under periods of lockdown and other emergencies.
The Consumer Price Index, or CPI, is a key economic indicator in most countries, giving 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…
Improving energy efficiency is a cost-effective means to support economic development while contributing to climate action. On a national scale, energy efficiency helps strengthen energy security, reduce energy expenditure, slow down energy demand growth, reduce investment needs for new generation…
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…
Integrated management of water, energy and land resources, while protecting ecosystems, remains a substantial challenge in the Western Balkans. The Water-Food-Energy-Ecosystems (WEFE) Nexus approach offers solutions that can reconcile potentially conflicting interests as they compete for the same…
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 (…
Water, health, climate change and disaster risk reduction are interlinked and interdependent. For example, with climate change, floods and droughts increase in both intensity and frequency. Floods can damage water and sanitation infrastructure, disrupt essential public service provision, undermine…
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…
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…
Water scarcity and pollution is increasing worldwide, as a result of the rising economic demands for water, population growth and rapid urbanisation, exacerbated by ecosystem losses and climate change. Water-related risks can negatively affect sustainable development, human health and well-being, …
