The Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer logo was developed to provide a distinct brand for the two treaties across various communication assets and applications. The visual identity guideline is designed to provide a comprehensive overview of applications and correct use of the logo.

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!

Dear Parties to the Montreal Protocol and other Stakeholders,

I am pleased to confirm the theme for this year’s World Ozone Day on 16 September.  It is:

Montreal Protocol: fixing the ozone layer and reducing climate change

This year’s theme aims to highlight and reiterate the positive impact of the Montreal Protocol on ozone layer recovery and reducing climate change, especially through the Kigali Amendment, which phases down hydrofluorocarbons (HFCs), a group of strong greenhouse gases.

With universal ratification and full implementation of the Kigali Amendment, the avoided warming by 2100 is estimated to be up to 0.5º C. Combined with energy efficiency measures while phasing down HFCs, these gains could potentially double.

Our planet is heating up. Average temperatures are soaring and with it the demand for cooling. This could also increase the amount of HFCs being used and emitted. Universal ratification and implementation of the Amendment to phase down HFCs from cooling systems and make them more sustainable is a critical climate warming mitigation tool. 

With the theme visualized in the posters, we are inviting all parties to join the celebration of World Ozone Day and use the assets created to raise awareness among the public on the important work of the Montreal Protocol to safeguard us and the planet.

As always, the World Ozone Day theme and taglines are available in all the six official UN languages on the WOD 2023 website.

To further support your World Ozone Day communication activities, the Secretariat will also develop a comprehensive social media pack in all the six official UN languages along with additional materials such as the video message from UNEP’s Executive Director, which will be made available for further dissemination nearer to World Ozone Day 2023 here

As you prepare for your events, we would also be pleased to receive any information on your planned commemoration of World Ozone Day 2023 to be featured on our website and social media channels (Instagram, Twitter, Facebook and LinkedIn)

As in-person events again are the norm, the Secretariat is pleased to provide limited financial assistance to selected developing countries to contribute towards organizing their national activities to commemorate the day. The Secretariat invites interested parties to submit their plans of celebration activities, including a planned budget, and requests for assistance by Friday, 30 June 2023. Kindly send them to the Secretariat at mea-ozoneinfo@un.org with a copy to stephanie.haysmith@un.org

As in previous years, the United Nations Secretary-General’s message for World Ozone Day will be shared prior to the day.

In the meantime, please do not hesitate to contact the Secretariat for any clarification or further information you may require at mea.ozoneinfo@un.org or stephanie.haysmith@un.org

Yours sincerely

Dear Sir/Madam,

Pursuant to paragraph 9 of Article 2 of the Montreal Protocol on Substances that Deplete the Ozone Layer, the Ozone Secretariat is circulating a proposal submitted by Cuba to adjust the Montreal Protocol.

The text of the adjustments is being circulated as received without formal editing and has been posted on the OEWG45 and MOP35meeting portals for the information of the parties to the Protocol. Translated text of the adjustments in other official languages of the United Nations will be posted on the meeting portals as soon as they become available.

Sincerely,

Article

The production of chlorofluorocarbons (CFCs) that would ultimately be released to the atmosphere was banned globally in 2010 under the Montreal Protocol. Here we use measurements combined with an atmospheric transport model to show how atmospheric abundances and emissions of five CFCs increased between 2010 and 2020, contrary to the goals of the phase-out.

Dear Sir/Madam,

Please find attached the invitation for the forty-fifth meeting of the Open-ended Working Group of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer and the workshop on strengthening effective implementation and enforcement of the Montreal Protocol.
