New Tool Maps California’s Biggest Greenhouse Gas Emitters

Interactive map pinpoints the polluters next door

In this Google Earth view, the height of the "balloon" location markers indicates the volume of greenhouse gas emissions.

Wondering where all the petroleum refineries are located in California? Curious about which industries in your area emit the most greenhouse gases? Or which counties have the most big industrial polluters, and which don’t have any at all?

A new interactive map from the California Air Resources Board taps the versatility of Google Earth software to transform eye-glazing spreadsheet data into a visual, if wonky, feast.

The map shows the locations and greenhouse gas emissions of about 625 facilities — the largest industrial greenhouse gas emitters in the state. The graphical tool can filter by type of facility (cement plant, refinery, electricity generation), by county or air district. You can use the satellite view to see a facility’s physical footprint, then switch over to Google Earth to see how its carbon footprint stacks up against other emitters. The EPA released a similar map earlier this year, but without all the Google Earth bells and whistles. Continue reading
