Tracking air quality in California

created Jun 05, 2018 11:43 AM

This post is meant to accompany the recent Current Context issue on auto emissions standards, “Who’s Driving Air Quality?” There are a number of Education and the Environment Initiative lessons that will deepen student learning on the relationship between the environment and transportation, pollution, and government policy and regulations. See the final page of the issue for links to these lessons.

In addition, you may find the CalEPA CalEnviroScreen tool a helpful one for your classroom discussions linking issues of government regulations, economics, and history to current environmental concerns in the state.

What is CalEnviroScreen?

CalEnviroScreen is a mapping tool that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution’s effects.

CalEnviroScreen uses environmental, health, and socioeconomic information to produce scores for every census tract in the state.

The scores are mapped so that different communities can be compared. An area with a high score is one that experiences a much higher pollution burden than areas with low scores.

CalEnviroScreen ranks communities based on data that are available from state and federal government sources.

Visit https://oehha.ca.gov/calenviroscreen to use the mapping tool to learn about pollution within your school’s zip code, or different areas of California.

As a class, you may want to consider what patterns are detectable among the areas of pollution? What industries or freeways exist within the areas shaded red and orange? What sort of industries are located within the areas shaded red and orange? What is the average cost of housing in these polluted areas versus the non-polluted areas? What questions do you have about this data? If you could speak to your city council or state legislature, what would you like to ask these elected officials, and what measures would you like to see them take to address these issues of pollution?
