Panama Environmental Quality

Panama Now Breathes the Cleanest Air on the Planet. Yes, Cleaner Than Costa Rica.

According to the 2025 IQAir World Air Quality Report, Panama is the only Central American country meeting WHO air quality standards, with PM2.5 levels consistently under 5 µg/m³—making it one of only 13 countries worldwide with WHO-compliant clean air, while Costa Rica does not meet this threshold.
