Environmental Management System (EMS)
In support of the efforts of the United Nations Secretariat to create climate-smart entities that are aligned with the recommendations made by the Intergovernmental Panel on Climate Change in its 2018 special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, 2 and in order to reduce greenhouse gas emissions from its operations and facilities by 2030, the Ozone Secretariat has developed an environmental management system (EMS) framework adopted in 2022 to mitigate and reduce its carbon emissions, particularly for its travel and external events. The system will record and report on the activities and outcomes of the work of the Ozone Secretariat.

Greening the Blue Report 2022 shows UN System Accelerating Efforts on Environmental Governance & Training
The annual Greening the Blue Report – The UN system’s environmental footprint and efforts to reduce it shows the progress both at the UN system-wide level and entity level of implementing the Strategy for Sustainability Management in the United Nations System 2020-2030, Phase I: Environmental Sustainability in the Area of Management. The 2022 edition of the Greening the Blue Report, which provides 2021 data and was published on 13 December 2022, reveals the UN system is accelerating efforts particularly on environmental governance and environmental training.
In 2021, the UN’s operations and facilities emitted ~1.2 million tonnes of CO2eq in total or 4 tonnes CO2eq per capita. The UN system’s GHG emissions by source were 29% from air travel, 56% from facilities, and 15% from other forms of travel.
For the Ozone Secretariat specifically, our operations and facilities emitted 5 tCO2eq in total or 0.29tCO2eq per capita, which is below the UN average. If we breakdown our emissions by source for 2021, 0% came from air travel, none from other travel, and the remaining 100% came from our facilities.
We are also pleased to announce that we are one of UN entities that were climate neutral for 2021, meaning that we offset 100% of our greenhouse gas emissions. This is the 8th year in a row that we are climate neutral.
Around 316 kg/person of waste was generated for the whole UN system in 2021. At the Secretariat, we generated 45 kg/person of waste.
The average water consumption by the UN System in 2021, was 37 m3 per UN personnel per year. In comparison, we used around 15 m3 per person last year.
Green travel and event tips
Did you know that if you…
Attendees are faced with a multitude of choices when participating at an event. As these examples illustrate, small actions can really add-up!
While the Ozone Secretariat is already offsetting the carbon impact of all participants from its meetings, you may be able to consider other ways to reduce your footprint. Action is not required but encouraged where possible. Every little helps and adopting new habits will build up our collective efforts over time. Each action, even just one, makes a difference!
- Replace short flights with rail trips, if possible.
- opt for direct routes that avoid additional emissions associated with multiple take-offs and landings.
- Voluntarily lower your flight class to avoid the higher-footprint of business class trips.
- Shift meals to plant-based alternatives where possible.
- Use public transit or share transport for local trips.
- Seek out accommodation that has a green guest programme or have earned an eco-certification.
- Stay at accommodation that is within walking distance of event venues.
- Participate in your hotel's linen-reuse programme.
- Bring a refillable tumbler for beverages to use at our plastic-free hydration stations.
- Download any electronic documents for use onsite. Print outs will not be provided, but device charging is available.
- Participate in the venue's recycling programme.
