Semiconductors - Emissions Estimate Calculator Page

This page was last reviewed April 3, 2017


The emissions estimate calculators (calculators) are designed to assist in benchmarking and calculating greenhouse gas (GHG) emissions from semiconductor operations in California.  The calculators 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 calculators are not mandatory, but help 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.
