Pakistan's environmental health score in the 2026 EPI was particularly weak in which specific indicator?

Explanation: Pakistan's weakest area in the 2026 Environmental Performance Index was environmental health, where it ranked 175th globally with a score of just 14.57, driven largely by an ambient PM2.5 score of 2.42, placing it 162nd worldwide on that single indicator. The index also measured exposure to nitrogen dioxide, sulfur dioxide, ozone and carbon monoxide. Provincial authorities, particularly in Punjab, have intensified enforcement and technology-based monitoring in response to chronic smog problems in cities such as Lahore.
