#CleanAirForAll: How air pollution impacts vegetation


Air pollution can have a negative impact on vegetation. Tropospheric (ground-level) ozone is considered one of the most damaging phytotoxic air pollutants. Ozone is a secondary air pollutant and a greenhouse gas. It is produced from reactions between the primary air pollutants nitrogen oxides (sources: transport and industry) and volatile organic compounds (sources: petrol, natural gas, paints, certain tree species) during warm and sunny weather. Surface ozone concentrations vary around the world. While in recent years, ozone levels have become more stable in Europe and have declined in North America, levels in rapidly developing regions continue to rise. Ozone is a transboundary pollutant, meaning that precursors can travel far from their point of production before ozone is formed. Ozone concentrations can be particularly high in rural areas downwind of cities.

What: Visualise the air quality in India using AiR, an Android-based mobile application. AiR considers the air quality measured by Central Pollution Control Board (CPCB), in a locality that is detected by the users’ GPS or in a locality of users’ choice, and visualizes various air pollutants present in the locality and displays them in the users’ surroundings. AiR also creates awareness in an interactive manner about the different pollutants, sources, and their impacts on health. The app can be used to view air pollutants across 220 stations in India.

Op-ed: Curbing air pollution from ships in the Mediterranean


Under COVID-19 lockdowns, many took to the internet to enthuse about clean air and blue skies. The confined masses shared pictures of wild animals roaming in deserted cities, including a photo purporting to show dolphins in the canals of Venice. Some of those photos may have been inaccurate or outright fake, but the enthusiasm signalled a longing for a healthy environment.

In the search for the pandemic’s silver lining, there may be a temptation to accept that healing the environment comes with plunging millions into joblessness as economies grind to a halt. We must reject this notion because the health of nature and the wellbeing of humans go hand in hand. Over the last few months, UNEP has repeatedly called upon governments to build back greener. UNEP’s Mediterranean Action Plan (UNEP/MAP)—which works to underpin the implementation of the Convention for the Protection of the Marine Environment and the Coastal Region of the Mediterranean (Barcelona Convention) by 21 Mediterranean countries and the European Union—has called for a green renaissance in Mare Nostrum. As the region continues to grapple with a set of intertwined crises, which now includes the coronavirus pandemic, the journey to a green recovery may begin with relatively small steps.

Message from head of the United Nations Economic Commission for Europe ahead of the International Day of Clean Air for blue skies

Olga Algayerova

While COVID-19-related disruptions may have impacted people’s mobility and slowed cross-border movements of people and goods this year, pollution knows no travel restrictions. Air pollutants, travelling through our atmosphere, can harm people and the environment even thousands of kilometres from their point of emissions.

Air pollution has been dubbed the ‘invisible killer’, responsible for a staggering 7 million deaths per year, according to the World Health Organization – more than from Malaria, Tuberculosis and AIDS combined. As we find out more about COVID-19, some scientists also suggest that people who live in polluted areas might be more susceptible to develop severe symptoms.

Read the full Op-ed here.

Olga Algayerova is the United Nations Under-Secretary-General and Executive Secretary of the United Nations Economic Commission for Europe (UNECE). She previously served as Permanent Representative of Slovakia to the International Organizations in Vienna, Austria (2012-2017); President, Slovak Millennium Development Goals (2010-2012); State Secretary, Ministry of Foreign Affairs (2006-2010) and Corporate Export Manager, Zentiva International (2004-2006).
