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…
An exhibition of urban sketches by Architect Norman Foster is opening today at the Palais des Nations on the occasion of the UNECE Ministerial Meeting on Urban Development, Housing and Land Management (6-8 October).  The sketches present visions of city planning that incorporate concepts of…
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…
A coordinated response is necessary for promoting and implementing the circular economy agenda globally. Concrete commitments from governments, businesses, international organizations, civil society and other stakeholders will be key to building the sustainable, resilient and low-carbon economy…
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.  This…
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…
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 …
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 (…
Decarbonizing transport and mobility remains a critical policy challenge, for which we must seize the recovery from the COVID-19 pandemic as a unique opportunity to accelerate progress. Decarbonization is one example of an issue where transport, health, and environment all meet – an intersection…
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…
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…
