About California Clean Air Day

When it comes to air pollution, we can all do our part. Whether you’re an individual, business, government agency or nonprofit organization, there are things we all can do to improve air quality and protect public health. In a state with some of the worst air pollution in the United States, it is imperative that we do.

California Clean Air Day is built on the idea that shared experiences unite people to action to improve our community health. By joining together for a unified day of action we can create new habits to clear the air for all members of California’s diverse communities.

California Clean Air Day is a project of the Coalition for Clean Air.

About the Clean Air Pledge

The Clean Air Pledge allows individuals and organizations to commit to do our part to clear the air, through actions big and small. When you take the Clean Air Day Pledge, you will see two options: to register as an individual and/or household or to register on behalf of an organization.

Individual Pledge

Be a part of a community of pledgers that included more than 1.6 million Californians in 2020. Take the pledge to choose from a menu of items that make a big difference. Choose from each of our three main categories (Switching Things Out, Planting Something, and Reducing Vehicle) to triple your impact! You can plant a tree, for example, or try out public transit or biking for the day.

Organization Pledge

Are you a business, school, governmental entity, non-profit organization or healthcare provider? Then sign up to take the organization pledge. There you will find a series of questions related to your type of organization, with the number of employees participating being a key component, as well as what business practices and educational efforts might be modified on or for Clean Air Day.

This year we have also provided an option for organizations to be assigned a code that their employees can use when making their individual Clean Air Pledge, allowing you to get a report of the number of employees who participated for your own engagement purposes. Participating organizations will be listed on our website.

Get Involved

In addition to making your Clean Air Pledge, there are a number of ways you can get involved in California Clean Air Day. As a business, you can provide support as a sponsor and plan to have your employees volunteer at one of the Clean Air Day events around the state. Local organizations can promote Clean Air Day and help their community have higher participation, and you can even plan your own California Clean Air Day event. We invite every California city and jurisdiction to pass a resolution declaring clean air day, and if yours hasn’t, let them know how easy it is to do. There are many ways to get involved, let us know your idea and what you’re planning to do.
