Dear Parties to the Montreal Protocol and other Stakeholders,

As we fast approach World Ozone Day, I am pleased to inform you that the final assets, available in all UN languages, to help you promote and celebrate this special day, have been finalized.

The video message from UNEP’s Executive Director (English only) and the statement from the United Nations Secretary General, as well as a specially commissioned video to mark WOD 2023, are now available on our dedicated WOD 2023 website. A library of social media tiles – some animated – combined with suggested messaging for ease of use, that capture this year’s theme Montreal Protocol: fixing the ozone layer and reducing climate change can also be found there.

The entire World Ozone Day 2023 awareness raising toolkit is also available on the WOD2023 Trello board.

I hope that the tools we have developed help you to highlight and reiterate the positive impact of the Montreal Protocol on ozone layer recovery and reducing climate change. Especially emphasizing the Kigali Amendment, which through the phase-down of hydrofluorocarbons (HFCs) and improved efficiency in the cooling sector, will provide additional climate mitigation benefits.

Since my last message on World Ozone Day, climate records have been broken, with unprecedented wildfires and floods raging. We need universal ratification and implementation of the Amendment more than ever. Let us use this World Ozone Day to actively promote the Kigali Amendment and reach universal ratification.

As you prepare for your events, please share any information on your planned commemoration of World Ozone Day 2023 with our Communications and Information Officer stephanie.haysmith@un.org to be featured on our website and social media channels (InstagramX (formerly Twitter), Facebook and LinkedIn). When posting on your social media channels be sure to tag the Secretariat @UNEPozone and use #WorldOzone.

Let me take this opportunity to wish you all a successful and happy World Ozone Day 2023!

Yours sincerely,

====

Ref:  Oz.Sec./Decision XXXIV/3/Request for Information                                                                                                    27 June 2023

With reference to decision XXXIV/3, adopted by the Thirty-Fourth Meeting of the Parties to the Montreal Protocol, allow me to draw your attention to paragraph 4 of the decision, which requests the Ozone Secretariat to:

(a) organize a one-day workshop in 2023, back to back with the Meeting of the Parties, to share information, experiences and lessons learned, and assess challenges related to ways of improving availability and accessibility of energy-efficient equipment and equipment using low- or zero-global-warming-potential (GWP) alternatives during the implementation of the Kigali Amendment; and

(b) prepare a report of existing policies addressing the interlinkages between phasing down HFCs and enhancing energy efficiency.

The report by the Secretariat will feature an integrated approach to addressing the energy efficiency aspects of the refrigerant transition and HFC phase-down and include information about various policies implemented around the world, aiming to share lessons learned and address challenges related to the availability and accessibility of energy-efficient equipment with low- or zero-GWP refrigerants. The report will serve as a background document for a one-day workshop scheduled to be held in Nairobi on 22 October 2023.

In this regard, we would appreciate it if you could share any information you may find pertinent under paragraph 4(b) of decision XXXIV/3, focusing on policies that address energy efficiency and transition to low and zero-GWP alternatives in the sectors using HFCs and other substances controlled under the Montreal Protocol.

The Ozone Secretariat would be grateful if any such information could be sent to Liazzat Rabbiosi (rabbiosi@un.org), with a copy to mea-ozoneinfo@un.org, by 28 July 2023 if possible, to enable timely preparation of the report.

Scientific articles
WOM

Until 2016, WMO, in collaboration with the European Ozone Research Coordinating Unit, published periodic Arctic and Antarctic Ozone Bulletins. They contained information and updates on the development of the ozone layer over the course of the year and were targeted at WMO Members who operate atmospheric monitoring stations and satellites to observe ozone and related parameters globally.

After seven years of interruption, the WMO/Global Atmosphere Watch (GAW) Ozone and UV Bulletin 2023 is launched!
