The Ozone Secretariat’s mission is to facilitate and support the Parties to the Vienna Convention and the Montreal Protocol and other stakeholders as appropriate, in implementing actions to protect and heal the ozone layer against adverse impacts resulting from its modification, thus protecting human health and the environment, including minimizing impacts on climate.




Since 2014, the Ozone Secretariat has maintained climate neutrality by measuring the carbon footprint of all meetings held and operations conducted under the Vienna Convention and the Montreal Protocol and offset the greenhouse gas (GHG) emissions created.

For 2016, the Secretariat purchased, through the United Nations Framework Convention on Climate Change (UNFCCC) certified emission reductions (CERs) equivalent to 2,215 tons of carbon dioxide, the GHG emissions associated with travels to the meetings for all participants, including travels to meetings of assessment panels, and related operations in 2016.

Most of the offset emissions were from meeting participants – Secretariat-funded and self-paying. The Secretariat offset the entire flight footprint to make the meetings climate-neutral. Secretariat staff travel accounted for less than 2 per cent of total air travel emissions.

The emissions were measured using a web-based carbon calculator created by the International Civil Aviation Organization (ICAO).

The CERs were purchased from the Adaptation Fund, which finances projects and programmes to help developing countries to adapt to the negative effects of climate change. 


Next steps


The Ozone Secretariat will continue to ensure climate neutrality by measuring the carbon footprint of all future Vienna Convention and Montreal Protocol meetings, including the meetings of the assessment panels of the Montreal Protocol, and related operations, and offsetting the associated greenhouse gas emissions.
