Who We Are
Clean Air Liberia is a PM2.5 monitoring and open-data initiative for Greater Monrovia, launched with EPIC Air Quality Fund support and implemented by the Kigali Collaborative Research Center alongside United Methodist University in Liberia.
What Drives Us
Our Mission
To reduce air pollution across Liberia through monitoring, education, and advocacy — protecting the health of every community.
Our Vision
A Liberia where every person breathes clean, healthy air and where air quality data drives government policy and public action.
Our Values
Community-first, science-backed, transparent, and committed to long-term environmental justice for all Liberians.
Our Story
Built to close a data gap
Liberia had almost no routine PM2.5 evidence. In February 2025, the Kigali Collaborative Research Center (KCRC) won EPIC Air Quality Fund support to change that, partnering with United Methodist University (UMU) in Monrovia to design, install, and maintain the country's first low-cost sensor network — and to share every reading openly.
Since deployment began in April 2025, we've installed PM2.5 sensors across busy traffic corridors, dense neighborhoods, and public institutions in Greater Monrovia, completing the network on December 19, 2025, and publishing data openly via OpenAQ since May 2025. Along the way we've trained the student and technical teams who keep it running, and written the maintenance playbooks so the network doesn't depend on any one person.
The impact is starting to show beyond our own sensors: the Environmental Protection Agency now requires businesses to install air quality monitors, local media are connecting air pollution to heart disease and stroke in ways that reach the public, and a student-led advocacy group at United Methodist University has grown out of our training workshops — a sign that clean air is becoming a shared community priority, not just a project we run.

Operating Honestly
We publish the gaps, not just the highlights
Liberia's power grid and mobile connectivity vary widely by region, and our sensor network reflects those realities. Rather than smoothing over outages, every monitoring site on our live dashboard shows its current status — online, power-limited, or connectivity-limited — so the people relying on this data can judge its confidence for themselves.
