Ozone Layer to Recover by 2050

Nigeria reaches stage three in Ozone-Depleting substances elimination plan, announced in April.

UN Secretary-General Antonio Guterres announced on World Ozone Day, September 16, that the ozone layer is on track for full recovery.

The ozone layer plays a crucial role in protecting humans and the environment from harmful ultraviolet radiation from the sun.

In the 1970s, scientists discovered that human-made chemicals like chlorofluorocarbons were causing the ozone layer to thin.

In response, countries signed the Montreal Protocol, a global treaty aimed at phasing out ozone-damaging substances and regulating ozone-depleting substances (ODS).

Guterres marked World Ozone Day on September 16 by highlighting the need for urgent action on climate solutions, including sustainable refrigerants and energy efficiency, to avert a climate crisis by mid-century.

He said, “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.

“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) which are 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.”

Nigeria's Minister of State for Environment, Iziaq Salako, revealed in April that the federal government has advanced to phase three in its efforts to phase out ozone-depleting substances.
