New multilateralism, focused on creating synergies between local, national, regional and global efforts, combined with practical, forward-looking solutions are needed to address the pressing challenges facing cities across the globe, including the coronavirus pandemic, rapid urbanization, and…
With the review of the amended Protocol to Abate Acidification, Eutrophication and Ground-Level Ozone (Gothenburg Protocol) under the UNECE Convention on Long-range Transboundary Air Pollution well underway, experts further discussed the sufficiency and effectiveness of current measures at the 60th…
The transition to a decarbonized energy sector is a critical step for keeping global warming below 2°C. To succeed, countries will need to phase out, or at least substantially limit the use of coal. While the benefits of the green transition are numerous, it will require a deep structural shift…
Cities have the power to accelerate the achievement of the 2030 Agenda Sustainable Development Goals (SDGs) through their work at the local level. Examples of this will be presented and discussed at the H22 +50 Session (31 May 2022), and Dialogue of Eminent Experts on smart, sustainable, and…
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…
In light of the global focus on decarbonization, which is critical to achieve the goal of keeping global warming below 2°C compared to pre-industrial levels, the energy sector must undergo profound modernization, with a focus on phasing down unabated coal extraction and use. However, to meet…
Improving energy efficiency is one of the most cost-effective options for climate action and to meet growing energy demand in most countries. It contributes to energy security, a better environment, improved quality of life, and economic well-being. Out of all sectors of economic activity, the…
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 –…
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…
The commitment to keep global warming to well below 2°C compared to pre-industrial levels requires decarbonization in all economic sectors and reduction of emissions of all potent greenhouse gases. In practice, this means modernization of the energy sector with a focus on phasing out unabated coal…
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…
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…
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…
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 (…
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…
