Welcome to the Facility GHG Emissions Visualization and Analysis Tool

This online tool enables users to query, view, and analyze greenhouse gases (GHG) emissions from large facilities in California.

         GHG emissions data were collected through ARBís Mandatory Greenhouse Gas Reporting Program (MRR).

         The data used in this tool do not reflect the total GHG emissions in California. For complete GHG emissions information, please visit ARB's Greenhouse Gas Emission Inventory.

         Only GHG emissions directly emitted from California MRR facilities are represented.

         GHG emissions from imported electricity and fuel suppliers are not included.

         Not all of the entities covered by the Cap-and-Trade Regulation are presented in this tool. Please read the Legal Disclaimer for more information.

         The primary industrial sectors of facilities were reconciled for consistency between the old and new reporting regulations.

         ARB will update this tool periodically when new GHG emissions data become available.

Users can find facilities and associated GHG emissions at the state, regional, and local levels, and display the data on maps, charts and in tabular formats. The following California map layers are integrated into the tool to help users view facilities and GHG emissions within various geographic boundaries:

         Air Basins

         Air Districts

         Counties

         Zip Codes

         Townships

 

Here are some highlights of the toolís functionalities and usages:

         Users can search and select facilities by name, location, industrial sector, and by a selected GHG emissions level.

         Users can view GHG emissions from individual facilities or aggregated GHG emissions from a group of facilities defined by year, geographic region, and industrial sector.

         Users can view GHG emissions in multiple formats, including maps, charts, and GHG emissions data tables.

         Users can track GHG emission trends over the time at the individual facility, a cluster of facilities and by industrial sector.

         Users can create and save customized maps and charts, and download the GHG emissions data as an Excel spreadsheet.

         Using the GHG emissions spatial calculator, users can draw circular, rectangular or polygon shapes on the map, and summarize GHG emissions from facilities in the user-defined areas.

         Users can sort tables and charts based on category names and GHG emissions.

         Users can sort and display only those facilities that are covered by the cap-and-trade regulation.

         The tool features multiple intelligent interactions between emission tables, maps and charts.

For example, when users group GHG emissions by county, the county map will automatically loaded on the map. Further, by clicking on a county name in the GHG emission table, all facilities in that county will bounce on the map, making them standing out from the rest of the facilities.

         The tool integrates Google search and geocoding functions to help locate a place and/or facility on the map.
