"The careful mix of authoritative science and collaborative action that has defined the Protocol for more than 30 years and was set to heal our ozone layer is precisely why the Kigali Amendment holds such promise for climate action in future".

The Assessment, which is meant to add to the scientific basis for decisions made by the Parties to the Montreal Protocol, also presents updated scenarios for hastening ozone recovery through: Complete elimination of controlled and uncontrolled emissions of substances such as carbon tetrachloride and dichloromethane, Bank recapture and destruction of chlorofluorocarbons (CFCs), halons, and hydrochlorofluorocarbons (HCFCs) and Elimination of HCFC and methyl bromide production, as well as the Mitigation of nitrous oxide emissions. Without the ozone, life on earth would be subject to massively harmful ultraviolet rays from our sun, the likes of which would have devastating effects on our future.

The ozone layer appears to be healing itself, after years of depletion due to harsh man-made chemicals. Scientists worked hard to prove that certain chemicals, namely CFCs (chlorofluorocarbon), were rapidly eating away at our planet's protective shield, and eventually lawmakers took notice, initiating a worldwide effort to ban their use.

"It's really good news", report co-chairman Paul Newman, chief Earth scientist at NASA's Goddard Space Flight Center, told the Associated Press.

The Kigali Amendment is set to revise targets under the Montreal Protocol, and will mandate the search for alternatives to hydrofluorocarbons (HFCs). It's a big deal since 10 percent of the upper ozone layer was gone in the 1990s, Newman told CNBC. This year, the ozone hole over the South Pole totalled almost 25 million square kilometers - 16% smaller than the 2006 peak.

Updated projections by climate change experts said the Antarctic ozone hole is expected to close, with column ozone values returning to 80s levels by about 2060.

The ozone layer is on track to fully fix itself in 50 years, a new Union Nations report says, and that is good news for your health.

The UN report estimates that the world can avoid up to 0.5 degree celsius of global warming this century if it is implemented.

And the replacements now being used to cool cars and refrigerators need to be replaced themselves with chemicals that don't worsen global warming, Newman said.

Pablo Campana, minister of Production, Foreign Trade and Investment, stated at the opening ceremony that 'being the venue of the Meeting of the Parties shows our country's compliance with the Montreal Protocol, and this is an ideal formu to spread the commitment by the national government to the industrial and sustainable development.
