UNDERSTAND | Clean Air Scorecard city score
The overall clean air score provides a quick snapshot on the overall status of clean air management in a city covering the three major indexes. Check the table below on what the overall Clean Air Score means.
| Overall Clean Air Score Category | ||
|---|---|---|
| Category | Score Band | Description |
| Fully developed | 81–100 | Key components of clean air management complete. Strong mandate for air pollution and GHG management and strong sector-based and integrated policies, regulations and institutions to address major sources of pollution (e.g., transport, industry, energy and area sources). Policies and actions contribute to achieving levels equivalent to prescribed WHO guidelines and interim targets for air pollution. |
| Maturing | 61–80 | Key Components of clean air management complete and some integration with other major sectors (e.g., transport, health and energy sectors). Policies and actions have achieved some success in reducing AP/GHG emissions but air quality levels still exceed healthy levels prescribed by the WHO. Management efforts in all sector sources need to be intensified to bring down emissions further. |
| Emerging | 41–60 | Majority of key components of clean air management are in place. Policies and actions to reduce emissions from identified major sources need to be enhanced. Sector-based institutions need to upgrade technical and management capacity. |
| Developing | 21–40 | GHG and AP emissions are increasing and air quality declining. Clean air management activities are scattered in different organizations with limited collaboration. Needs to invest in strengthening components of basic air quality management and collaboration between stakeholders. |
| Underdeveloped | 0–20 | Ad hoc clean air management; lack in emissions and ambient air quality standards; Needs to build capacity for basic air quality and GHG emissions management. |
