About the data



2008 Baseline GHG Emission Inventory for San José (Table 2 on page 8 of document; first published June 2011)

2014 San José Community-wide Greenhouse Gas (GHG) Inventory Update (published October 2016)

City of San Jose 2017 Inventory of Community Greenhouse Gas Emissions (published April 2019)

Population data

American Community Survey 3- and 5-year estimates covering the years 2006 to 2018. The American Community Survey is a yearly survey providing detailed population and housing information for the entire U.S.

Jobs data

2008 and 2009 data came from the Monthly Jobs Total spreadsheet on the City of San Jose’s Open Data Portal

Data from 2010 onward came from the City of San José Office of Economic Development. Each value is the sum of the number of payroll jobs, received from the California Employment Development Department, and an estimate of the number of self-employed jobs, from the American Community Survey.


The 2008 Baseline GHG Emission Inventory for San José did not calculate emissions from potable water delivery or fugitive and process emissions.

Margins of Error (MOE) are provided for every American Community Survey estimate. The MOE measure the possible variation of the estimate around the population value with a confidence level defined by the Census Bureau (standard – 90 percent).
