Our operations, primarily the manufacture of imaging and printing products, require the use of several chemicals listed on the U.S. Environmental Protection Agency (EPA) Toxics Release Inventory (TRI). We have equipment and processes designed to monitor and control releases that do occur and report site releases under relevant local law. For this report, we extend TRI reporting criteria to the five manufacturing sites worldwide that account for all of HP's reportable TRI releases.
Releases of these materials from HP manufacturing operations continue to decrease. This is in part because we have eliminated or scaled down the HP processes that use these chemicals due to changes in business operations.

- * The substances with global totals greater than 1 tonne are shown. TRI reports are due to the U.S. EPA July 1 each year, so the most recently completed reporting year is 2009.
- ** The increase in air emissions and TRI material shipped off-site for treatment or disposal (most notably of glycol ethers)from 2007 to 2008 is due to the integration of data from acquired operations. Data for these operations became available in 2008.
