How do I use this resource?
There are many features to this tool. To get started, select years of interest, geographic region, sectors, and pollutants from the left panel. Results will be displayed in the main map. One helpful way to narrow results is to set a lower limit on the emissions (at the bottom of the left panel). You can display additional data on the map by selecting from the "map layers" tab, including community vulnerability data from CalEnviroScreen. Results are also show in a table to the right of the map. You can select the charts tab to display pie or bar charts. You can see the individual data points in the "data" tab, and there you can also download the emissions data. There is a user's guide and video tutorial available in the "help" tab.
