The Montreal Protocol shows what is possible when science, diplomacy, and business cooperate to implement international environmental agreements. When the people became aware of a hole in the ozone layer over Antarctica—and damage to the protective layer of atmosphere around the world—leaders around the world coordinated action on ozone depleting …
The amount of greenhouse gases in the atmosphere reached yet another new record high in 2014, continuing a relentless rise which is fuelling climate change and will make the planet more dangerous and inhospitable for future generations. The World Meteorological Organization’s Greenhouse Gas Bulletin says that between 1990 and 2014 …
Research published at a meeting of the Montreal Protocol in Dubai reveals the serious human health and economic consequences averted by concerted and coordinated global action on the protecting the ozone layer. Synthesis of the 2014 Reports of the Scientific, Environmental Effects, and Technology & Economic Assessment Panels of the …
The U.N.'s weather and climate agency said on Thursday there was no cause for alarm about a record-size hole this month in the ozone layer, that shields life on earth from the sun, as it should shrink again. The ozone hole that appears over Antarctica fluctuates in size, normally reaching …
Europe continues to make progress in phasing out chemicals which damage the ozone layer according to a new report from the European Environment Agency (EEA). The report considers the use of more than 200 chemicals controlled by the Montreal Protocol and EU legislation.
The Antarctic ozone hole would have been 40% bigger by now if ozone-depleting chemicals had not been banned in the 1980s, according to research. Models also show that at certain times, a large hole would have opened up at the other end of the globe. The Arctic hole would have …
At the rate things are going, the Earth in the coming decades could cease to be a "safe operating space" for human beings. That is the conclusion of a new paper published in the journal Science by 18 researchers trying to gauge the breaking points in the natural world. The …
Scientific Assessment of Ozone Depletion: 2014 is the quadrennial report of the Scientific Assessment Panel (SAP) of the Montreal Protocol on Substances that Deplete the Ozone Layer. The SAP assesses the state of the depletion of the ozone layer and relevant atmospheric science issues every four years and provides Parties …
In 1987, the Montreal Protocol phased out the use of chlorofluorocarbons (CFCs), an ozone-depleting substance (ODS) used as coolants in refrigeration and air conditioning. Unfortunately, the chemicals increasingly being deployed in their place, hydrofluorocarbons (HFCs) are themselves exceptionally potent greenhouse gases. They are often called super greenhouse gases because their …
On SEPTEMBER 23rd 120-odd presidents and prime ministers will gather in New York for a UN meeting on climate change. It is the first time the subject has brought so many leaders together since the ill-fated Copenhagen summit of 2009. Now, as then, they will assert that reining in global …
The Earth's protective ozone layer is well on track to recovery in the next few decades thanks to concerted international action against ozone depleting substances, according to a new assessment by 300 scientists. The Assessment for Decision-Makers, a summary document of the Scientific Assessment of Ozone Depletion 2014, is being …
The Environmental Protection Agency is proposing to jettison yet another formerly popular compound used in air conditioners, vending machines and aerosol spray cans, citing its impact on global warming. In an announcement Thursday, the federal regulatory agency said that it is considering banning certain hydrofluorocarbons (HFCs), compounds used in many …
Chlorofluorocarbons (CFCs) are the primary cause of ozone depletion, and they also contribute to global climate change. With the global phaseout of CFCs and the coming phaseout of hydrochlorofluorocarbons (HCFCs), the substitute hydrofluorocarbons (HFCs) are increasingly used. While CFCs were originally used mainly in applications such as spray cans and …
This guide provides an introduction and simple overview of the issues related to international standards in the refrigeration and airconditioning sector and how they can be useful in the context of the phase-out of hydrochlorofluorocarbons (HCFCs) in developing countries as required by the Montreal Protocol on Substances that Deplete the …
The European Parliament on Wednesday backed a law to curb the use of "super" greenhouse gases used in fridges and air conditioners, which have a global warming potential thousands of times greater than carbon dioxide. Lawmakers meeting in Strasbourg, France voted 644 to 19 in favour of a European Commission …
WARSAW: Laughing gas is, indeed, no laughing matter. The United Nation Environment Programme (UNEP) on Thursday released an eye-opening report on the sidelines of the ongoing climate talks, warning that nitrous oxide (N2O) — commonly known as laughing gas — with 300 times the global warming potential of carbon dioxide …
Industrialised countries should phase out HFC says Sunita Narain, Director-General, CSE in this presentation at CSE Annual South Asian Media Briefing Workshop on Climate Change, 2013 held from September 18-19, 2013. HFC: A lesson on how companies make money to save the world - Presentation by Sunita Narain, Director-General, CSE …
Speakers at a seminar on Monday stressed the need for developing a sense of urgency for stopping the use of ozone depleting substances to avert adverse impact on global climate. Ozone depleting substances hamper balance of atmosphere by destructing the ozone layer, leading to the increase of global warming, they …
Various events would be organized to mark World Ozone Preservation Day on Monday by the regional office of UP Pollution Control Board. Regional officer Mohd Sikandar said that a symposium would be organised at Saras Hall of Vikas Bhawan on 'preservation of ozone layer'. It would be attended by students, …
This second edition of "Vital Ozone Graphics" includes details on the latest decisions taken by the Parties to the Montreal Protocol to accelerate the phase out of HCFCs and outlines the implications this has on the use of replacement chemicals. The Resource Kit also focuses on the linkages and interconnections …
