Welcome to the Emissions Analytical and Visualization Tool
This online tool will help you to query, view, and analyze emissions of greenhouse gases (GHG), criteria air pollutants (CAP) and toxic air pollutants (TAP) from large facilities in California. The emissions data employed in this tool are from the following sources:
Beside of facilities and emissions information, integrated into the tool are map layers of geographic boundaries, air quality monitoring sites and other environmental stressors, along with demographic and social-economic data. This enables users to evaluate and analyze emissions in a broad context. The additional map layers include:
The tool is designed to serve several ARB's air quality and climate change programs, including but not limited to:
With the tool, users can find facilities and associated emissions at the state, regional, local and community levels, and present the data in maps, charts and tabular formats. Using the toolís rich built-in utilities, itís easier than ever to analyze emissions trends, patterns, and potential impacts on local air quality and communities.† Here are some highlights of the toolís functionalities and usages:
∑ Users can search and select facilities by name, location, industrial sector, and filter facilities by emission levels of any selected pollutants.
∑ Users can view emissions from individual facilities or aggregated emissions from a group of facilities defined by year, geographic region, and industrial sector.
∑ Users can view emissions in multiple formats, including maps, charts, and data tables.
∑ Users can compare emissions of multiple pollutants, and track emission trends over the time.
∑ Users can create, edit, and save customized maps and charts, and download the data used in the analysis.
∑ Users can drill-down an emission chart and find out contributions from sub-level categories, and eventually from individual facilities.
∑ Users can define circular, rectangular and polygon-shape areas on the map, and analyze emissions from the self-defined geographic areas.
∑ Users can sort emission tables and charts based on either category names or emissions;
∑ Intelligent interactions between emission tables, maps and charts. For example, when users group emissions by county, the county map will be automatically loaded on the map. Click on a county name in the emission table, all facilities in that county will bounce on the map, making them standing out from the rest.
∑ Built-in Place Search and Geocoding functions in the tool.
