Global environmental problems are some of the most pressing issues that humanity is facing. There are few examples of success at resolving them; the fight to protect the ozone layer is one of them. This paper provides evidence that the Montreal Protocol’s restrictions on chlorofluorocarbons (CFCs) triggered a substantial increase …
The demand of active cooling systems such as air conditioners and chillers is increasing rapidly. This leads to an increase in emissions of Chlorofluorocarbons (CFC) and Hydro-Chlorofluorocarbons (HCFC), which negatively impact the Earth's ozone layer. Over the past years, ozone depletion has become a serious concern both at the national …
Industries in north-eastern China have released large quantities of an ozone-depleting gas into the atmosphere in violation of an international treaty, scientists have said. Since 2013, annual emissions of the banned chemical Chlorofluorocarbon-11 (CFC-11) from that region have increased by about 7,000 tonnes, according to a report in peer-reviewed journal …
Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization (WMO). There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather. The WMO Greenhouse Gas …
An environmental pressure group claimed that Chinese factories are illegally using ozone-depleting CFCs, which have recently seen a spike in emissions that has baffled scientists. The Environmental Investigation Agency (EIA) campaign group said 18 factories in 10 Chinese provinces they looked into admitted to using banned chlorofluorocarbons. Producers and traders …
The Montreal Protocol was designed to protect the stratospheric ozone layer by enabling reductions in the abundance of ozone-depleting substances such as chlorofluorocarbons (CFCs) in the atmosphere. The reduction in the atmospheric concentration of trichlorofluoromethane (CFC-11) has made the second-largest contribution to the decline in the total atmospheric concentration of …
The ozone layer - which protects us from harmful ultraviolet radiation - is recovering at the poles, but unexpected decreases in part of the atmosphere may be preventing recovery at lower latitudes. Global ozone has been declining since the 1970s owing to certain man-made chemicals. Since these were banned, parts …
(Seychelles News Agency) - Seychelles is focusing on ozone-layer-friendly technological appliances as it joins the second phase of the Green Cooling Africa Initiative. Through the initiative, Seychelles will be able to replace appliances such as refrigerators and air conditioning units containing hydrochlorofluorocarbon (HCFCs) and chlorofluorocarbons (CFCs) with those using natural …
The restoration of the globe’s protective shield of ozone will be delayed by decades if fast-rising emissions of a chemical used in paint stripper are not curbed, new research has revealed. Atmospheric levels of the chemical have doubled in the last decade and its use is not restricted by the …
This report summarises the data reported by undertakings in accordance with the ODS Regulation for 2015 and looks at the major trends since 2006. Aggregated data reported by companies on the import, export, production, destruction, and feedstock and process agent use of ozone-depleting substances in the European Union.
Hydrofluorocarbons (HFCs) are often used as substitutes for ozone-depleting substances (ODSs) in various sectors, including refrigeration, air-conditioning, aerosols, fire extinguishers, and foam blowing. In addition, HFC-23 is generated as a by-product of chlorodifluoromethane (HCFC-22) production for feedstock use in industry and for emissive use. HFCs are the fastest-growing group of …
US Secretary of State John Kerry was among those who took part in high-level talks on Friday. The conference ended early on Sunday. A global agreement on cutting the use of hydrofluorocarbons (HFCs) – potent greenhouse gases used in aerosols, refrigerants and air conditioning – seems within grasp, delegates said …
A global agreement on cutting the use of hydrofluorocarbons (HFCs) - potent greenhouse gases used in aerosols, refrigerants and air conditioning - seems within grasp, delegates said on Sunday after ten days of talks on climate change in Vienna. A final deal is expected to be reached at a meeting …
Ministers and high-level representatives of 25 countries, including Rwanda, have backed the adoption of an ambitious amendment to the Montreal Protocol to phase-down the use of hydrofluorocarbons (HFCs). Hydrochlorofluorocarbons are compounds consisting of hydrogen, chlorine, fluorine, and carbon atoms that destroy the stratospheric ozone layer essential to life on Earth …
When the world moved to phase out ozone-destroying chlorofluorcarbons, or CFCs, it solved one enormous and urgent environmental problem — but it left behind another. CFCs were bad for the ozone layer and also caused a great deal of global warming to boot. But a key substitute — hydrofluorocarbons, or …
In a major new paper in the influential journal Science, a team of researchers report strikingly good news about a 30-year old environmental problem. The Antarctic ozone "hole" - which, when it was first identified in the mid-1980s, focused public attention like few other pieces of environmental news - has …
Climate change has been dear to both Prime Minister Narendra Modi and President Barack Obama who, along with some other global leaders, played a crucial role in ensuring that a new post-2020 climate agreement was successfully negotiated in Paris last December. India has agreed to a major commitment on a …
Illegal factories process 95% of all e-waste and are flouting safety norms; they are also taking business away from licensed recyclers ohammed Sabir spent his childhood learning to dismantle broken circuit boards. It was a reliable source of income for a long time, but the health hazards of handling toxic …
Greenhouse Gas Data Management: Building Systems for Corporate/Facility-Level Reporting is intended to serve as a reference document for regulators, GHG reporting program and system administrators, and IT/development teams on all aspects of designing and developing GHG data management systems. The guidance report: Highlights the legal, regulatory, policy, institutional, and technical …
