Reliable and verifiable data are essential to managing greenhouse gas (GHG) emissions from our operations. We measure, verify and publicly report annual GHG emissions from HP-owned and HP-leased facilities worldwide. We also report our California emissions to the California Climate Action Registry (CCAR). During this process, we correct any data errors in HP’s tracking system, investigate any change in performance greater than 5 percent, and conduct a root cause analysis if we discover a systemic error. For electricity we purchase from utility companies, we adjust conversion factors to reflect the most recent data available.
In addition to our internal review, we commission independent auditor Bureau Veritas Certification to verify our GHG emissions measurements and annual reporting under the protocols of the World Economic Forum's (WEF) Global Greenhouse Gas Registry. Bureau Veritas Certification also verified our 2006 California GHG emissions using the protocols from the CCAR.1 We will commission a review of our 2007 GHG emissions data.
See details regarding the WEF and CCAR verification of our 2006 data online. HP also submitted a recent response to the Carbon Disclosure Project.
“In summary, I had a high degree of confidence that the greenhouse gas information reported was generally accurate. There were some minor errors in reporting data noted during the verification; however, these discrepancies were minor in relation to the amount of data reviewed. I have observed improvements in the data collection methodology and tool accuracy since previous GHG verifications, and I was impressed with the HP management's attention to detail and dedication to continually improving their methodology and accuracy of data collection and reporting.”
—Carol Osgood, Auditor, Bureau Veritas Certification
1Because of the timing required for the verification process, the data verified lags the report year by one year.
