Briefings

For over a decade, U.S. diplomatic missions worldwide independently tracked air quality in cities, but recent data suggests a significant rise in pollution levels after these embassies ceased reporting. The evidence indicates a clear disconnect between official monitoring and actual environmental conditions, though the specific magnitude of the increase and the exact timeline of the cessation remain unclear.

Key points

• U.S. embassies and consulates have provided independent air-quality readings in cities globally for more than a decade.
• Recent data indicates a significant rise in pollution levels following the cessation of these embassy reports.

Context

This finding highlights a potential gap in global environmental monitoring, as diplomatic missions historically tracked air quality but recent data suggests a sharp increase in pollution after they stopped reporting.

Limitations

The evidence is limited to the stated fact that embassies stopped reporting; specific dates of the rise, the exact magnitude of pollution increase, and the reasons for the cessation are not provided.
