Semiconductors - Emissions Estimate Calculator Page

This page was last reviewed January 5, 2015


The emissions estimate calculator (tool) is designed to assist in benchmarking and calculating greenhouse gas (GHG) emissions from semiconductor operations in California.  This tool can be used to help owners and operators calculate the 2006 Intergovernmental Panel on Climate Change (IPCC) Tier 2b emission calculations, required by the semiconductor regulation, which became effective on January 1, 2010.

The use of the tool is not mandatory, but helps to simplify reporting for industry, promote consistency in reports, and lessen the review time for district personnel.  The owners and operators are still ultimately responsible for submitting accurate and complete reports in accordance with the semiconductor regulation.
