At the rate things are going, the Earth in the coming decades could cease to be a "safe operating space" for human beings.

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.

In 1987, the Montreal Protocol phased out the use of chlorofluorocarbons (CFCs), an ozone-depleting substance (ODS) used as coolants in refrigeration

On SEPTEMBER 23rd 120-odd presidents and prime ministers will gather in New York for a UN meeting on climate change.

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 published by the UNEP and the WMO, and is the first comprehensive update in four years. The stratospheric ozone layer, a fragile shield of gas, protects the Earth from harmful ultraviolet rays of the sun. Without the Montreal Protocol and associated agreements, atmospheric levels of ozone depleting substances could have increased tenfold by 2050. According to global models, the Protocol will have prevented 2 million cases of skin cancer annually by 2030, averted damage to human eyes and immune systems, and protected wildlife and agriculture, according to UNEP.

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 war

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 were released within a year after production, concern about the ozone layer led to reductions in rapid-release applications, and the relative importance of slower-release applications grew.

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 Ozone L

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
