Safe to Breathe? Summary

Core Content

This report, Safe to Breathe? Analyses and Recommendations for Improving Ambient Air Quality Management in Ethiopia, provides an in-depth analysis of ambient air quality (AQ) issues in Ethiopia, with a particular focus on Addis Ababa (AA). It outlines the health and economic impacts of air pollution, identifies key pollution sources, and proposes a comprehensive action plan to improve AQ management.

Main Issues and Challenges

• Air Pollution as a Global and Local Concern:
  Air pollution is a major global health and economic risk, with LMICs being disproportionately affected. In Ethiopia, the capital city, Addis Ababa, is experiencing significant air quality degradation due to rapid urbanization, economic growth, and increasing mobility.

• Health and Economic Costs:
  Air pollution contributes to a range of health issues, including respiratory and cardiovascular diseases, and is associated with premature deaths and disability. The report estimates that in AA, ambient PM₂.₅ pollution causes about 1,600 premature deaths and 4,100 Years Lived with Disability (YLDs) annually, equivalent to 1.3% of the city’s GDP.

• Pollution Sources:
  The primary sources of air pollution in AA include vehicle emissions, residential fuel combustion, industrial activities, and open waste burning. The transport sector is the largest contributor, responsible for 29% of PM₂.₅, 97% of NOₓ, and 96% of CO₂ emissions.

• Weak Institutional and Policy Frameworks:
  Ethiopia lacks a specific AQM framework and has inconsistent enforcement of environmental regulations. There is a lack of clarity in the mandates of government agencies, and financial and institutional capacity for AQM is limited.

• Insufficient AQ Monitoring and Data:
  AQ monitoring is relatively new in Ethiopia, with only a few stations releasing continuous data. The use of low-cost sensors has increased, but they face operational challenges such as power and internet connectivity. The data shows that AA’s annual average PM₂.₅ concentration is 2–3 times higher than WHO guidelines, indicating unhealthy air quality.

Key Recommendations

1. Regulation and Policy Reforms

• Clearly define roles and mandates of federal and municipal agencies for AQM.
• Introduce taxation and pricing policies to promote cleaner vehicles (e.g., hybrids and electric vehicles) and phase out polluting ones.
• Upgrade AQ standards, including PM₂.₅ standards, to align with WHO guidelines.
• Implement low sulfur fuel standards (starting at 50 ppm, progressing to 10 ppm) and align with Euro 4/IV vehicle emission standards nationwide.

2. AQM Strategy and Plan

• Develop a national AQM strategy and plan, with support from AA and other cities.
• Guide future AQM activities with a clear and actionable strategy.

3. Budgeting and Capacity Building

• Strengthen financial and implementation capacity of line agencies responsible for AQM.
• Allocate specific budgets for AQM at both national and municipal levels.
• Encourage private sector investments in AQM initiatives.

4. AQ Monitoring

• Establish a robust national AQ monitoring program and network.
• Strengthen existing AQ monitoring systems and ensure continuous data release.

5. Data Collection and Analytics

• Deepen analytical work on AQ data collection, dispersion modeling, emission inventory, and source apportionment.
• Conduct transport modeling and spatio-temporal analysis of traffic and vehicle emissions.
• Perform impact and economic valuation assessments to support informed decision-making.

6. Awareness Raising and Behavioral Change

• Increase public awareness of air pollution impacts and promote behavioral changes to reduce pollution.
• Encourage the adoption of cleaner fuels and technologies among households and vehicle owners.

7. Vehicle Emissions Control

• Prioritize and implement air pollution control measures in the transport sector due to its significant contribution to ambient air pollution.
• Improve emission inspection and maintenance (IM) systems to ensure compliance.

8. Control of Point and Area Sources

• Address industrial, waste, and construction-related pollution through targeted measures.
• Control industrial emissions, improve solid waste collection, reduce open burning, and implement best practices for managing construction and road dust.

Conclusion

The report emphasizes the need for an integrated air quality management (IAQM) approach to address the complex and multi-faceted nature of air pollution in Ethiopia. It calls for strengthening institutional and policy frameworks, improving data collection and monitoring, and implementing targeted mitigation measures in key sectors such as transport, industry, and waste management. By addressing these issues, Ethiopia can improve public health, reduce economic losses, and enhance the sustainability of its urban development.
