Zimbabwe’s Bold Move: Phasing Out Ozone-Depleting Substances for a Healthier Planet

By Obey Musiwa, Herald Reporter

Recently, Zimbabwe celebrated the International Day for the Preservation of the Ozone Layer with a symposium focused on the country’s commitment to the Montreal Protocol. This annual event highlighted Zimbabwe’s strides in eliminating ozone-depleting substances while promoting a healthier environment.

This year’s theme, “40 Years of the Vienna Convention: From Science to Global Action,” reflects a strong dedication to finding eco-friendly alternatives. These efforts aim not only to protect the Earth but also to improve public health for future generations.

Mr. Tadeous Chifamba, the permanent secretary for Environment, Climate and Wildlife, emphasized the importance of phasing out harmful chemicals used in Refrigeration and Air Conditioning (RAC). “The Montreal Protocol seeks to gradually eliminate man-made chemicals that damage the ozone layer,” he stated. To enforce this, his ministry collaborates with Customs and Environmental Officers at major entry points nationwide.

These harmful chemicals not only deplete the protective ozone layer but also contribute to global warming. As the world transitions from HFCs to safer refrigerants, like hydrocarbons, Zimbabwe aligns itself to combat both ozone depletion and climate change. This move is essential for improving life on Earth.

Dr. Ayodele Odusola from UNDP also spoke at the event. She highlighted a key partnership with the Zimbabwean government in implementing projects to support the Montreal Protocol and the Kigali Amendment. Notably, CAPRI, one of the largest refrigeration companies, is shifting to ISO-B10HC600A, a non-ozone-depleting refrigerant. UNDP is also aiding in modifying production lines and staff training to ensure a smooth transition.

George Chaumba, project manager at the National Ozone Unit, discussed the successes of global cooperation under the Vienna Convention. He noted that the Montreal Protocol has played a critical role in tackling climate change. Adopting hydrocarbon technologies not only supports ozone preservation but also lowers carbon dioxide emissions.

Interestingly, recent research shows that if the current efforts continue, the ozone layer is expected to recover fully by 2060. This recovery will significantly reduce UV radiation exposure and further mitigate climate change impacts.

Overall, Zimbabwe’s actions on this crucial day reinforce its commitment to a healthier planet. These upcoming changes reflect both global trends and local initiatives, emphasizing the importance of continued collaboration in environmental protection.
