About us

JustAir is a small and growing team dedicated to the belief that everyone has the right to breathe clean air. We strive to be true collaborators with environmental justice leaders, resident groups, governments, public health advocates, and industries who are committed to making air quality information more accessible. In collaboration with our partners, we give communities the data they need to create the future we all deserve.

We Value

Community knowledge, culture, history & science.

We balance research and data with local knowledge, culture, and history to support decision-making and drive change.

Justice, equity & inclusivity.

We filter everything we do through a lens of inclusivity and strive to build a more just and equitable world.

Pride & ownership.

We take pride in the work we do and strive to ensure everyone involved - from the team to community partners - are full owners in the work.


We conduct our work with openness and honesty, ensuring information is accessible and straightforward.

Iteration, Process & Growth.

We seek out new knowledge, pilot, implement feedback, and iterate processes to ensure we’re achieving desired outcomes and working in ways that live up to our values.

Yes before no.

We explore ideas and assume the best intentions in our collaborators. We experiment, pilot, and we find a way to work with partners who believe in a hopeful future, just like we do.

Gratitude and recognition.

We say thank you, we recognize that our team and partners are here by choice, and we celebrate our wins, no matter how small. We acknowledge and celebrate the longtime efforts of environmental justice leaders, whose enduring dedication has created the path for our work today.


We innovate, take unique approaches, and work to solve problems in new, impactful ways.


We put our values into practice every day.

Our Mission:

Our mission is to protect the 20,000 breaths each person takes every day. We put air quality data into the hands of communities to increase well-being and drive positive, locally-led change. We do this by building trusted partnerships, providing accessible air quality insights, fostering community-led action, and growing a team that puts our values into practice every day. 

Our Vision:

We envision a world where clean air is a universal standard. With our partners, we are changing the narrative on how people organize, collect data, and collaborate to ensure everyone has access to clean, healthy air.
