Anything is possible.

1980s: Scientists found the Antarctic ozone “hole,” driven by CFCs. The world acted with the 1987 Montreal Protocol. Now recovery is on track with repair by 2040. Proof policy works. We can do it again with carbon emissions. #Ozone #MontrealProtocol #ClimateHope #ActOnClimate

More great news for the weekend with Pakistan 🇵🇰 confirmed as the 169th party to ratify the Kigali Amendment 👏 Fantastic news. Why? Because this incredible cooling tool could potentially avoid up to 1°C in avoided warming by the end of this century! ozone.unep.org

At @unepozone.bsky.social we encourage the parties to the #MontrealProtocol due to attend #MOP37 to bring their own water bottles so that we can ensure our meetings do not contribute to the use of and build up of unnecessary singe-use plastic waste bit.ly/3WUnklu 🌿

Great news for the weekend! The CAR 🇨🇫 has just become the 168th party to ratify the Kigali Amendment 👏 With only 30 countries to go this is fantastic. Why? Because this incredible cooling tool could avoid up to 1°C in avoided warming by end of 2100! ozone.unep.org 🌍
