World Bank Supports China in Phasing Out Ozone-Depleting Substances
EPA's Achievements in Stratospheric Ozone Protection Progress Report to the Montreal Protocol, the Parties to the Protocol meet annually and take a variety of The Kigali Amendment () Exitextended controls to phase down the Panel (EEAP) assesses the various effects of ozone layer depletion. To meet this request, the Scientific Assessment Panel (SAP), the Environmental . some indications of recovery in stratospheric ozone in the Assessment. . Protocol controls, and CH3Br has natural sources, which results in a natural. As a result, SMEs were able to successfully transition to new non-ozone depleting technologies and .. meeting in May called for proposals to demonstrate.
These in turn are altering natural ecosystems and food production. These climate changes are likely having a similar if not greater impact than more UV radiation.
This report summarises the impact of both ozone loss and the associated increase in ultraviolet radiation on the environment and human health. But while the Montreal Protocol is a success story, the Southern Hemisphere still faces the threat of climate change from rising greenhouse gases.
There is still much to do.
Good Up High Bad Nearby - What is Ozone?
Changing the weather In recent years, climate scientists have shown that the ozone hole has had a profound impact on weather systems throughout the Southern Hemisphere, especially during summer. This has prevented sea ice melt and rising sea-levels. By changing atmospheric circulation, the ozone hole modifies wind, rain and snowfall patterns across the Southern Hemisphere.
It can worsen bronchitis, emphysema, and asthma. Repeated exposure may permanently scar lung tissue. Healthy people also experience difficulty breathing when exposed to ozone pollution.
Because ozone forms in hot weather, anyone who spends time outdoors in the summer may be affected, particularly children, older people, outdoor workers and people exercising. Millions of Americans live in areas where the national ozone health standards are exceeded. Ground-level or "bad" ozone also damages vegetation and ecosystems. It leads to reduced agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased susceptibility to diseases, pests and other stresses such as harsh weather.
Ground-level ozone also damages the foliage of trees and other plants, affecting the landscape of cities, national parks and forests, and recreation areas.

EPA, state, and cities have instituted a variety of multi-faceted programs to meet these health-based standards. Throughout the country, additional programs are being put into place to cut NOx and VOC emissions from vehicles, industrial facilities, and electric utilities. Voluntary programs also encourage communities to adopt practices, such as carpooling, to reduce harmful emissions.
We live with ozone every day. It can protect life on earth or harm it, but we have the power to influence ozone's impact by the way we live. High-Altitude "Good" Ozone Protect yourself against sunburn. When the UV Index is "high" or "very high": Limit outdoor activities between 10 am and 4 pm, when the sun is most intense.
Twenty minutes before going outside, liberally apply a broad-spectrum sunscreen with a Sun Protection Factor SPF of at least Reapply every two hours or after swimming or sweating.
For UV Index forecasts, check local media reports or visit: Make sure technicians that work on your car or home air conditioners or refrigerator are certified to recover the refrigerant. Repair leaky air conditioning units before refilling them. Ground-Level "Bad" Ozone Check the air quality forecast in your area. In many places, ozone peaks in mid-afternoon to early evening. Change the time of day of strenuous outdoor activity to avoid these hours, or reduce the intensity of the activity.

Since that time, the Montreal Protocol has been repeatedly strengthened by both controlling additional ozone-depleting substances ODS as well as by moving up the date by which already controlled substances must be phased out.
In addition to adjustments and amendments to the Montreal Protocol, the Parties to the Protocol meet annually and take a variety of decisions aimed at enabling effective implementation of this important legal instrument.What Ever Happened To The Hole In The Ozone Layer?
More information on the current state of the ozone layer is found here. Amendments to the Montreal Protocol The London Amendment Exit changed the ODS emission schedule by requiring the complete phaseout of CFCs, halons, and carbon tetrachloride by in developed countries, and by in developing countries.
International Treaties and Cooperation about the Protection of the Stratospheric Ozone Layer
Methyl chloroform was also added to the list of controlled ODSs, with phaseout in developed countries targeted inand in for developing countries.
Under this agreement, CFCs, halons, carbon tetrachloride, and methyl chloroform were targeted for complete phaseout in in developed countries. In addition, methyl bromide consumption of methyl bromide was capped at levels.
The Montreal Amendment Exit included the phaseout of HCFCs in developing countries, as well as the phaseout of methyl bromide in developed and developing countries in andrespectively.
