Documentation of California's Greenhouse Gas Inventory
Main sources of sulfur hexafluoride
Greenhouse gas inventories involve a wide range of human activities. Estimating the amount of greenhouse gases generated by these activities requires using a multiplicity of data sources and a diverse set of methodologies. Storing, cataloging, and documenting such a multifaceted set of information is challenging. ARB staff has designed a custom relational database to hold California's greenhouse gas inventory information.
Online Documentation Pages
Each of the emission values contained in the detailed 2000-2011 inventory table by IPCC category has its own documentation page accessible through a hierarchical index based on the same categorization. The goal of these pages is to summarize all the information that was used by ARB staff to produce the particular emission value. With this information, the methodology used to derive the GHG estimates may be assessed and independently verified. These documentation pages are also accessible by economic sector and/or by activity through the inventory query tool.
Documentation pages for the 1990 inventory are accessible by IPCC category through the 1990 index. They are also accessible by economic sector and/or by activity through the 1990 inventory query tool.
