Global efforts to protect the climate and the ozone layer have received a further boost with the adoption of the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer by the parties at the 28th Meeting of the Parties in October 2016. A successful HFC phasedown is expected to avoid up to 0.4 degree Celsius of global temperature rise by 2100, while continuing to protect the ozone layer.

To highlight the tremendous work carried out by the Assessment Panels in support of the Montreal Protocol, a video was created showcasing the vital role that science plays in support of the Protocol, providing the parties with the necessary data to promote implementation, monitoring and reinforcing the need for continued compliance.

Spotlight on the Assessment Panels

The Synthesis Report comprises the combined key findings based on the three Assessment Reports of the Scientific Assessment Panel (SAP), the Environmental Effects Assessment Panel (EEAP) and the Technology and Economic Assessment Panel (TEAP). Based on new analyses and information, the advances in scientific understanding of ozone depletion help form the basis for decisions made by the parties.

Key Findings for 2019

The Ozone Secretariat introduced a logo for the Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer. The logo, visualising the earth and hand-drawn circles representing the ozone layer, symbolizes all life under the sun, which is protected by actions taken by the nations of the world under the Vienna Convention and the Montreal Protocol.

The ozone treaties handbooks are updated yearly with all decisions that parties to the Vienna Convention and to the Montreal Protocol take. They represent a crucial resource for the parties, experts, industries and other stakeholders. A new App is available for both Android and iPhones.

The country profile data, which provides an overview of data and information reported by each party, their ratification status, as well as information on the establishment of licensing systems for controlled substances, was developed to provide easy access to information on the reporting of the parties.
