Montreal Protocol Ozone Secretariat
@unepozone.bsky.social
The ozone layer, an invisible shield around the Earth protects all living things from the effects of the sun’s harmful ultraviolet radiation. Through the Protocol’s Kigali Amendment, countries are helping to avoid an estimated 0.5°C of warming by 2100.
📯 SIDE EVENTS starting in earnest at #MOP37. We have 6 daily, starting with 3 side events during the plenary lunchtime break.

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

It showed the power of countries coming together around science. A model we still need today.
