Guterres says Ozone layer on track to full recovery by 2050

UN secretary-general, Antonio Guterres has said that the ozone layer is on its path to recovery.

In the 1970s, scientists discovered that the ozone layer- which protects humans and the environment from harmful levels of ultraviolet radiation from the sun-was depleting due to the use of human-produced chemicals such as chlorofluorocarbons.

Subsequently, countries signed a global treaty known as the Montreal Protocol to phase-out substances that deplete the ozone layer, and regulate the production and consumption of chemicals referred to as ozone-depleting substances (ODS).

In his message to commemorate the World Ozone Day celebrated on September 16, Guterres said that climate solutions, including those concerning refrigerants and energy efficiency, are essential to prevent a climate crisis by mid-century.

“At a time when multilateralism is under severe strain, the Montreal Protocol to help protect the ozone layer stands out as a powerful symbol of hope. It is a reminder that when countries show political resolve for the common good, change is possible,” he was quoted as saying.

“In uniting the world to phase out the consumption and production of different ozone depleting substances, the Protocol has also contributed to shielding carbon sinks, protecting humanity’s health, and avoiding economic losses.

“The ozone layer, once an ailing patient, is on the road to recovery. Now, it’s time to go further.

“The Protocol’s Kigali Amendment — which focuses on phasing down hydrofluorocarbons (HFCs) – powerful climate-warming gases – can contribute to advancing climate mitigation efforts, protecting people and the planet. And that is needed more than ever as temperature records continue to shatter.

“If fully ratified and implemented, the Kigali Amendment could help avoid as much as 0.5 degrees Celsius of global heating by the end of this century. Four out of every five nations have ratified the Kigali Amendment, but the clock is ticking.

“On this World Ozone Day, let’s commit to making peace with our planet. Let’s commit to build on the success of the Montreal Protocol to show what international cooperation at its best can achieve.”
