Summary of Greening the Blue Report 2023

Core Content

The Greening the Blue Report 2023 provides a comprehensive overview of the United Nations (UN) system's environmental footprint and the efforts to reduce it in 2022. The report highlights the progress made by over 57 UN entities in addressing key environmental impact areas such as greenhouse gas (GHG) emissions, waste, air pollution, water and wastewater, and biodiversity, as well as the mainstreaming of environmental governance and management functions like procurement and human resources.

The report is structured based on the Sustainability Strategy I (2019-2030), which outlines the UN system's environmental objectives and management functions. It aims to evaluate whether the UN system is on track to meet these goals and to provide insights for further improvement.

Main Points

Environmental Impact Areas

• Greenhouse Gas Emissions:

  • Total emissions in 2022: 1.4 million tonnes of CO₂eq
  • Per capita emissions: 4.6 tonnes of CO₂eq
  • Emissions by source: 38% from air travel, 47% from facilities, 15% from other travel
  • The UN Secretariat accounts for 55% of the total emissions, with 773,000 tonnes of CO₂eq reported in 2022 for 120,000 personnel.

• Waste:

  • The UN system generated an average of 321 kg of waste per person in 2022.
  • IOM eliminated the use of plastic bags in its movement operations.

• Water and Wastewater:

  • The average water consumption per UN personnel was 49 m³ per year.
  • Santiago's Water Management Plan promotes conservation efforts.

• Biodiversity:

  • UNESCO personnel fully took ownership of a vegetable and biodiversity garden in 2022.

Management Functions

• Environmental Governance:

  • 7 UN entities met or exceeded the criteria for implementing an environmental management system (EMS).
  • 15 additional entities are approaching the criteria.

• Procurement:

  • 80% of construction waste was recycled due to effective procurement specifications at ESCAP.

• Human Resources:

  • 31 entities provided environmental training to their staff.
  • Mandatory training helped personnel in South Sudan make a positive environmental impact.

Key Efforts and Outcomes

• Climate Neutrality:

  • The UN system committed to offsetting 100% of unavoidable emissions by 2020.
  • As of the 2023 report, 92% of the reported 2022 GHG emissions were offset.
  • Offsets are achieved through Certified Emission Reductions (CERs) from projects under the Clean Development Mechanism (CDM), verified under the Kyoto Protocol.

• Renewable Electricity:

  • 31% of the UN system's electricity in 2022 came from renewable sources.
  • This includes electricity purchased from national grids, onsite solar, and generators using renewable fuels.

• Greening the Blue Community:

  • Composed of 57 entities, including GCF and other UN bodies.
  • Case studies are provided for each environmental impact area and management function, showcasing successful initiatives and practices.

Methodology and Reporting

• The report follows the Sustainability Strategy I framework and includes data from 2022.
• Data collection and inventory processes are detailed, with entity-specific data available on greeningtheblue.org/performance/entities.
• The report emphasizes reporting completeness, documenting the level of data provided by each entity.
• Comparisons with previous years are included where possible, but some data may not be fully comparable due to changes in methodologies or data collection practices.

Conclusion

The Greening the Blue Report 2023 reflects the UN system's ongoing commitment to environmental sustainability. While progress has been made, the report acknowledges the complexity and limitations in comparing results across years. It serves as both an informative tool and a source of inspiration for other organizations aiming to reduce their environmental footprint.

• ICAO provided the air travel emissions calculator.
• UNFCCC and UNOPS contributed offsetting options.
• ASR team at UNOPS shared data on sustainable procurement.
• Focal Points of the Working Group on Environmental Sustainability Management were instrumental in data collection and reporting.
