Greening the Blue Report 2024 edition shows UN System’s Progress on Environmental Sustainability
The UNEP Sustainable UN (SUN) 2024 Greening the Blue Report presents the environmental performance and sustainability efforts of the UN system and its operations worldwide. With offices and personnel worldwide, the UN System remains committed to supporting people and the planet by minimizing environmental harm.
This year’s report includes UN-wide environmental performance data from 2023, as well as good practices, covering 322,900 people across 58 UN entities worldwide.
Key Facts
Emissions
In 2023, the UN’s per capita GHG emissions increased from 4.6 (2022) to 4.8 tonnes of CO2 equivalent (2023). Total emissions increased by 9%. GHG emissions remained 24% below pre-pandemic levels.
For the Ozone Secretariat specifically, our operations and facilities emitted 453 tonnes CO2eq in total or 27 tonnes CO2eq per capita, a decrease from 2022. If we breakdown our emissions by source for 2023, 97 per cent came from air travel, 2 per cent from other travel, and the remaining 1 per cent came from our facilities, the same as for 2022.
10 years of climate neutrality
We are also pleased to announce that we are one of a few UN entities that were climate neutral for 2023, meaning that we offset 100% of our greenhouse gas emissions. This is the 10th year in a row that we are climate neutral.
Waste and water consumption
UN-wide, waste per capita decreased by 4% overall. In 2023, 31% of waste was reused, recycled, composted, or used for energy recovery, up from 13% in 2022. At the Secretariat, we generated 30 kg/person of waste, down from 36kg/person in 2022. The water consumption by the Secretariat for 2023 decreased to 215m3 compared to 253m3 in 2022.

Environmental Management System (EMS)
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 to mitigate and reduce its carbon emissions.
