Changing of the climate
On January 1, 2019, new international standards on the phased reduction of the consumption of hydrofluorocarbons - gases, which cause a strong warming, came into force. This is the Kigal Amendment to the Montreal Protocol.
To date, this new document has been ratified by 65 states. UNEP has called on all other countries to join an important agreement.
Proper implementation of the provisions of the Kigal Amendment and its support from governments, the private sector, and citizens will keep global warming at 0.4 degrees Celsius already this century. The Kigal Amendment will make an important contribution to the protection of the ozone layer and the achievement of the objectives of the Paris Agreement.
After all, today the temperature of the Earth is 1 degree Celsius higher than at the beginning of the 20th century. This is largely due to the increase in greenhouse gas emissions.
The Montreal Protocol on Substances that Deplete the Ozone Layer was signed on September 16, 1987. In particular, it prohibits the production and sale of hazardous substances that deplete the ozone layer. Within the framework of the Montreal Protocol, the production and use of about 100 types of chemicals has already been banned. Many of these substances contribute to global warming. Ozone protects the earth from ultraviolet radiation, which is the main cause of melanoma and other skin cancers.
The Kigal amendment provides for the phased reduction of hydrofluorocarbons, which are not ozone-depleting gases, but cause strong global warming - many times more than carbon dioxide. These organic substances are used in cooling systems.
The new agreement for different countries provides different terms for the withdrawal of hydrofluorocarbons from circulation. For example, Belarus, Kazakhstan, the Russian Federation, Tajikistan and Uzbekistan by 2020 will have to reduce their consumption by 5 percent from the current level, and by 2036 - by 85 percent.
