Read more about the mission of the Clean Air Catalyst

Air pollution is the greatest environmental threat to human health – causing more than 6 million premature deaths each year and affecting nearly every organ in the body.  It has profound impacts on climate, agriculture productivity, food security, biodiversity, and economic development.  We are overdue in cleaning up the air.

Join us to learn more about the Clean Air Catalyst, a new flagship program of USAID and a global consortium of organizations led by WRI and EDF.  We are working with communities on the frontlines of this global crisis to better understand local pollution sources and identify solutions that lead to sustained progress on cleaner, healthier air. Pilot cities include: Addis Ababa, Ethiopia; Indore, India; and Jakarta, Indonesia.

OpenAQ Global Community Series: Exploring Possibilities with the OpenAQ Low-cost Sensor Pilot Platform

Date: Thursday, February 25, 2021

Time: 11:00-12:30pm Eastern Time Zone

Why is low-cost sensor data important in the collective fight against air pollution? How does opening up low-cost sensor data on a global scale help shape the future of air quality data coverage and data sharing? This OpenAQ Global Community Series will offer a glimpse into the recently launched OpenAQ Low-cost Sensor Platform, an open-source data infrastructure that harmonizes diverse data sources from around the globe. We’ll be sharing OpenAQ’s motivation behind developing the platform, conducting a short demo on how to access the data on the platform, and facilitating a panel with key partners in the low-cost sensor community.

Breathe London Blueprint Launch: How can data supercharge efforts to lower air pollution in cities?

The evidence is clear: Dirty air is fatal and causes health inequities around the world. New technology is allowing us to map pollution street-by-street, identify hotspots and share unprecedented amounts of air quality data. The Breathe London pilot was an ambitious two-year project that measured pollution across the city using 100 lower-cost sensor ‘pods’ and specially-equipped Google Street View cars, serving as a world-leading example of how emerging technology can help accelerate clean air action.

On February 9, 2021, we held a discussion of key lessons from the pilot project and the launch of the Breathe London Blueprint, as well as how new efforts to leverage air quality data are shining a light on pollution at a scale and scope across the globe like never before.

Environmental Defense Fund released the Breathe London Blueprint to support your city’s future monitoring and air pollution data initiatives, and it can be found here.

Scaling Clean Air Actions by Hyperlocal Air Quality Monitoring: Lessons Learned and Recommendations
