World Ozone Day, 16 September 2025 Ozonaction
One 2019 study found some adults could potentially be consuming between 39,000 to 52,000 microplastics particles a year on average, depending on their location and what they do. “But what we do know for sure is that when they end up in the environment, they also end up pin up board in our food chain. “We’re just beginning to understand how microplastics travel and where they end up,” says Gardner. Research has shown that particles can move through the food web, as well as through soil, water, ice – even the air. However, microplastics find their way into the environment, once they’re there, they get around.
International Ozone Day is celebrated globally to recognize the work being done by stakeholders to include scientists, policy makers, multilateral agencies and technicians in the refrigeration and Air condition sectors. Through art, sports and education, Albanian youth conveyed the message of protecting the ozone layer and the climate, proving that environmental education is an investment for the present and the future, making young people active actors of change. Peduzzi finds there is apathy around climate change as often people don’t realize the massive impact that each degree of warming can have on the planet. There is a dedicated module on climate change, which includes daily updated graphs on the extent of Arctic and Antarctic sea ice.
Phase out of HCFCs – the Montreal Amendment
This year’s theme, ‘From Science to Global Action’, highlights the vital role of research, innovation, and international cooperation in protecting the ozone layer for present and future generations. The event, held under the global theme ‘From Science to Global Action’, focused on technologies and sustainable practices that support ozone layer protection and climate change mitigation. These activities were aimed at strengthening the knowledge of school teachers and school children and future specialists in refrigeration, air-conditioning, and food technology industries – sectors that play a critical role in ozone layer protection and energy efficiency.
Safeguarding the environment for future generations
The recent collapse of a 1,100km2 ice shelf in Antarctica came at a time of record high temperatures and is a symptom of a planet in climate crisis, experts say. Without significant action to lower greenhouse gas emissions, communities will reach these hard limits faster and begin to suffer irreparable damage from climate change, say experts. Some countries and communities can adapt to rising temperatures, lower precipitation and the other impacts of climate change. Climate skeptics have long argued that the computer models used to project climate change are unreliable at best and completely inaccurate at worst. But by ramping up financing and focusing on low-carbon development in key transport, agriculture and forestry, the world can get there. While the situation is dire, there is still a narrow window for humanity to avoid the worst of climate change.
Safeguarding the environment for future generations
With the full and sustained implementation of the Montreal Protocol, the ozone layer is projected to recover by the middle of this century. Such a “smart approach” can achieve the Montreal Protocol’s objective of eliminating HCFCs while at the same time achieving energy efficiency gains and CO2 emissions reduction — a “climate co-benefit.” Countries agreed to add HFCs to the list of controlled substances and approved a timeline for their gradual reduction by per cent by the late 2040s. While these chemicals do not deplete the stratospheric ozone layer, some of them have high GWPs ranging from 12 to 14,000. Another group of substances, hydrofluorocarbons (HFCs), were introduced as non-ozone depleting alternatives to support the timely phase-out of CFCs and HCFCs.
Bhutan Commemorates World Ozone Day 2025 under the Global Theme “From Science to Global Action”Bhutan joined the global community today in celebrating World Ozone Day 2025, celebrating the achievements of the Montreal Protocol and reaffirming the country’s commitment to protecting the ozone layer and addressing climate change. The webpage also highlights temperature anomalies and has a vast amount of data explaining and monitoring climate change. The Paris Agreement on climate change aims to limit average global temperature rise to “well below” 2°C, and preferably to 1.5°C, since pre-industrial times.
In 1985, governments adopted the Vienna Convention for the Protection of the Ozone Layer, which provided the framework for the Montreal Protocol to phase out ozone-depleting substances, including chlorofluorocarbons (CFCs). In the mid-1970s, scientists warned that man-made chemicals in everyday products like aerosols, foams, refrigerators and air-conditioners were harming the ozone layer. About the Montreal Protocol The Montreal Protocol is a global agreement to protect the Earth’s ozone layer by phasing out the chemicals that deplete it. For the first time, the Scientific Assessment Panel examined the potential effects on ozone of the intentional addition of aerosols into the stratosphere, known as stratospheric aerosol injection (SAI).
“With climate change affecting the atmosphere, there is need for concerted action to address climate challenges through the Kigali Amendment, which was adopted to phase down hydrofluorocarbons, substances with high global warming potential,” she said. The CS reiterated that protecting the ozone layer was crucial for safeguarding the health of present and future generations. Kenya reaffirms commitment to Ozone protection, calls for stronger climate action on World Ozone DayNAIROBI, Kenya, Sept 16 — Environment, Climate Change and Forestry Cabinet Secretary Deborah Barasa has called for stronger global and national efforts to protect the ozone layer and tackle climate change. Amman, Sept. 16 (Petra) — Jordan reaffirmed its international commitment to protecting the ozone layer on the occasion of the International Day for the Preservation of the Ozone Layer, highlighting significant progress achieved under the Vienna Convention and the Montreal Protocol.
- This is suitable for outreach to NOU staff, other government agencies and other stakeholders involved in the licensing and quotas process.
- With demand for these chemicals set to rise, experts say it is more urgent than ever for countries to ratify the Amendment.
- “But what we do know for sure is that when they end up in the environment, they also end up in our food chain.
- These are known as secondary microplastics.
World Environment Day on 5 June is the biggest international day for the environment. These funds enable agile, innovative solutions to climate change, nature and biodiversity loss, and pollution and waste. Bolstering waste collection and recycling systems would help prevent plastic products from escaping into the environment, where they break down into microplastics.
Phase down of HFCs – the Kigali Amendment
They were concerned this would cause krill populations to decline and have a knock-on effect to the species that rely on krill as a food source. Concerns raised in the mid-1970s that an increase in krill catches in the Southern Ocean could have a serious effect on populations of krill and other marine life, particularly on birds, seals and fish which depend on krill for food, led to the adoption of the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR)
The Montreal Protocol phases down the consumption and production of the different ODS in a step-wise manner, with different timetables for developed and developing countries (referred to as “Article 5 countries”). The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS). Over time discarded plastic products – like water bottles and cling wrap – can break down into microplastics. NAIROBI, 9 January 2023 – The ozone layer is on track to recover within four decades, with the global phaseout of ozone-depleting chemicals already benefitting efforts to mitigate climate change. It also provides examples of similar equipment databases used in other developed and developing countries. This is suitable for outreach to the general public and the key Montreal Protocol stakeholders.
The celebration highlights the crucial role of the Montreal Protocol in protecting the ozone layer, which acts as a shield for Earth against harmful ultraviolet radiation. With the Montreal Protocol adopted two years later, the world committed to global action to phase out ozone-depleting chlorofluorocarbons. The day is dedicated to raising awareness on issues related to the protection of the ozone layer and promoting activities that support the implementation of ozone treaties. As climate change and environmental challenges grow more severe, countries around the globe are celebrating this milestone, acknowledging the importance of science-based decisions and collective action.
A first step is for companies to stop adding unnecessary microplastics to products, Gardner says. How can you reduce the amount of microplastics in the environment? Another report found microplastics can make soil less fertile, hampering harvests. One study found they can slow the growth of a microscopic marine algae known as phytoplankton, the base of several aquatic food webs. Are microplastics damaging to plants, animals and the wider environment? Microplastics have been found throughout the human body, including in the walls of arteries.
AT A GLANCE: WORLD OZONE DAY ACTIVITIES AND CELEBRATIONS
The initiative aimed to raise awareness among young people about the importance of protecting the ozone layer, global challenges related to climate change, and practical steps that individuals can take to safeguard the environment. The theme underscores the critical role of science in alerting the world to emerging challenges in protecting the ozone layer and addressing climate change. The theme for World Ozone Day 2025 is ‘From science to global action’, emphasizing the power of scientific discovery to assist policy formulation and inspire international cooperation, demonstrating that collective action based on scientific evidence can protect our planet and its future. The Montreal Protocol and the Vienna Convention remain crucial for monitoring ozone and ultraviolet radiation levels, as well as https://chambleehighschoolaviation.com/ phasing out ozone-depleting substances and other harmful chemicals, including hydrofluorocarbons (HFCs), under the Kigali Amendment. The event, held at The George Hotel, brought together key leaders and stakeholders to celebrate the theme “From Science to Global Action.”
Why the global fight to tackle food waste has only just begun
Forty years ago, nations came together to take the first step in protecting the ozone layer — guided by science, united in action. Zimbabwe joins the global community in commemorating World Ozone DayZimbabwe today joins the international community in commemorating World Ozone Day and reaffirming its commitment to protecting the environment through the implementation of global climate agreements. The theme for World Ozone Day 2025, From Science to Global Action, captures the scientific essence of the global ozone protection journey – remembering how the world united to respond after the 1970s to 1980s discovery that human-made chemicals had caused severe thinning of the ozone layer. Crops, forests, and marine ecosystems, including coral reefs that are central to Palau’s environment and economy, are also vulnerable to damage from heightened UV exposure.
Phase down of HFCs – the Kigali Amendment
This is suitable for outreach to NOU staff, other government agencies and other stakeholders The Vienna Convention and Montreal Protocol are the blueprints for how we must address today’s global challenges – especially climate change. It is the only treaty which ever achieved universal ratification—signed by every country on earth and leading to successful global action to reverse the expanding ozone hole and continuing to protect both the ozone layer as well as the climate to this day. With the Montreal Protocol adopted two years later, the world agreed on global action to phase out ozone damaging chlorofluorocarbons. These must be aligned with limiting global temperature rise to 1.5°C and cover all sectors and greenhouse gases, including HFCs.
Safeguarding the environment for future generations
“It’s probably safe to say that microplastics are just about everywhere,” says Gardner, whose division works to counter plastic pollution in lakes, rivers and the ocean. According to one estimate, 2.7 million tonnes of microplastics seeped into the environment in 2020, an estimate expected to double by 2040. These are known as secondary microplastics. These are known as primary microplastics, like the microbeads intentionally added to face washes and other personal care products. One widely used approach defines microplastics as any fragment of plastic that is between 1 nanometer and 5 millimetres wide.

In March 2022, UNEP launched an updated version of its data, information and knowledge platform called the World Environment Situation Room. The United Nations has also released the ActNow campaign, which guides people on the individual choices they can make to limit global warming and reduce climate change. Key to curbing melting sea ice and ice sheets is mitigating climate change and keeping temperature rises in line with the Paris Agreement. But between March 16 and March 20, around the time the ice shelf is believed to have collapsed, the temperature was on average 35°C warmer, hitting a balmy-for-Antarctica -18°C on March 17. “The current concentration of greenhouse gases is higher than at any time in human history. It’s a very worrying signal,” said Pascal Peduzzi, Director of the Global Resource Information Database (GRID) – Geneva.
Improving cold chains to reduce food loss and for safer handling of vaccines are at the heart of the 2021 campaign for World Ozone Day on September 16. With demand for these chemicals set to rise, experts say it is more urgent than ever for countries to ratify the Amendment. Although the adoption of the Montreal Protocol marked a critical turning point, it was not a one-time fix.
The Fund’s objective is to provide financial and technical assistance to developing country parties to the Montreal Protocol whose annual per capita consumption and production of ODS is less than 0.3 kg to comply with the control measures of the Protocol. The treaty evolves over time in light of new scientific, technical, and economic developments, and it continues to be amended and adjusted. Developing and developed countries have equal but differentiated responsibilities, but most importantly, both groups of countries have binding, time-targeted, and measurable commitments. When released into the atmosphere, those chemicals damage the stratospheric ozone layer, Earth’s protective shield that protects humans and the environment from harmful levels of ultraviolet radiation from the sun.
Phase down of HFCs – the Kigali Amendment
That was in line with a widely read study from 2013, which found 97 per cent of peer-reviewed papers that examined the causes of climate change said it was human-caused. A 2021 study revealed that 99 per cent of peer-reviewed scientific literature found that climate change was human-induced. Some experts also believe climate change could lead to longer and more intense cold in some places due to changes in wind patterns and other atmospheric factors. In some areas, crop yields would decrease by more than https://cdinstitute.in/ half, threatening food security.
Substances such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have posed major challenges for developing countries over the years. The Protocol is widely regarded as the most successful environmental agreement in history, bringing countries together to phase out chemicals responsible for damaging the ozone layer. Nation leads in reducing ozone-depleting substancesChina has phased out 628,000 metric tons of ozone-depleting substances, accounting for half of the total reduction by developing countries as of last year, and is expected to phase out another 90,000 tons this year, according to the Ministry of Ecology and Environment. The ministry expressed hope that global warming could be reduced by up to 0.5°C by the end of the century if all nations continue to fully cooperate in protecting the ozone layer. She further encouraged all stakeholders to play their part in ensuring that the ozone layer is protected for future generations. The event saw participation from around 600 people, including government officials, employees, scouts, and girl guides.
HFCs do not directly deplete ozone, but are powerful climate climate change gases. The impact the Montreal Protocol has had on climate change mitigation cannot be overstressed. Examining novel technologies such as geoengineering for the first time, the panel warns of unintended impacts on the ozone layer. OzonAction is part of UN Environment Programme’s Law Division and serves 147 developing countries through the Compliance Assistance Programme. This is suitable for outreach to NOU staff, other government agencies and other stakeholders involved in the licensing and quotas process. The key functions of these systems include facilitating interactions and information sharing among licensing authorities, importers, exporters, and Customs.
Phase down of HFCs – the Kigali Amendment
In Article 5 countries, this HCFC phase-out is in full swing, with support from the Multilateral Fund for the implementation of multi-stage HCFC Phase out Management Plans (HPMPs), investment projects and capacity building activities. In fact, many developing countries have exceeded the reduction targets for phasing out ODS, with the support of the Multilateral Fund. Since its inception, the Multilateral Fund has supported over 8,600 projects including industrial conversion, technical assistance, training and capacity building worth over US$3.9 billion.

This month, delegates will be meeting in Bonn, Germany for a key conference on climate change. MapsofIndia has updated its Terms and Privacy Policy to give Users more transparency into the data this Website collects, how it is processed and the controls Users have on their personal data. What the parties to the Protocol have managed to accomplish since 1987 is unprecedented, and it continues to provide an inspiring example of what international cooperation at its best can achieve. Given all of these factors and more, the Montreal Protocol is considered to be one of the most successful environmental agreements of all time.
The world would also lose twice as many plants and vertebrate species and three times as many insects. While climate change is a natural process human activity is pushing it into overdrive. The Earth is heating up at its fastest rate in at least 2,000 years and is about 1.2°C hotter than it was in pre-industrial times. It is true that the planet’s temperature has long fluctuated, with periods of warming and cooling. “Most of the world rightly acknowledges that climate change is real,” says Dechen Tsering, Acting Director of the Climate Change Division at the United Nations Environment Programme (UNEP). But many believe – or at least say they believe – that climate change is not real, relying on a series of well-trodden myths to make their point.
“This day is an opportunity to reflect on the importance of ozone protection, while also highlighting it as an important key in the fight against climate change as many of the ozone depleting chemicals are potent greenhouse gases,” said Dr Dion George, Minister of Forestry, Fisheries and the Environment. In the 1970s, parties to the Antarctic Treaty raised concerns about a dramatic increase in fishing for krill, which are a key part of the Antarctic food web. We always strive to keep the data available with us updated and fresh all the time, in case you come across an incorrect data field, do let us know for us to take an immediate action. Throughout the implementation of the Montreal Protocol, developing countries have demonstrated that, with the right kind of assistance, they are willing, ready, and able to be full partners in global efforts to protect the environment. Under this treaty, all parties have specific responsibilities related to the phase out of the different groups of ODS, control of ODS trade, annual reporting of data, national licensing systems to control ODS imports and exports, and other matters.
But what exactly are microplastics, why are they concerning and what can the world do about them? If you’ve been following the global conversation around plastic pollution, you’ve probably heard of microplastics.
