HP is committed to making its global operations more energy efficient, seeking low-carbon energy sources where possible, and reducing employees’ business travel. These activities in turn help reduce our climate impact.

Our goal is to cut absolute greenhouse gas (GHG) emissions from our operations (not including travel) to 20% below 2005 levels by 2013. We adjust our baseline to account for acquisitions and divestitures.

In 2010, GHG emissions from our operations equaled 1.87 million tonnes of carbon dioxide equivalent (CO2e), over 9% less than 2009. We achieved this reduction as a result of:

  • Success in numerous energy-efficiency initiatives across HP, which helped to decrease overall energy use by 3% (See Energy efficiency for more information.)
  • A decrease of 12,000 square meters in data center floor area, due to continued integration and consolidation of HP Enterprise Services facilities following the 2008 EDS acquisition (See Energy efficiency for more information.)
  • More than doubling our renewable energy purchases (See Renewable energy for more information.)

In 2010, HP acquired several companies, including Palm and 3Com. As a result, we have restated our 2005 baseline for GHG emissions.

In addition to this section in our annual Global Citizenship Report, we also report our GHG emissions yearly through the Carbon Disclosure Project .

Sources of GHG emissions from operations

Energy use accounts for 98% of the GHG emissions generated by our operations and represents one of the largest costs of operating our facilities.

Refrigeration equipment, use of diesel for backup generators, and HP manufacturing processes generate the remaining 2% of our GHG emissions. This includes emissions from the use of perfluorocarbons (PFCs) for semiconductor manufacturing, which constituted less than 0.5% of our total GHG emissions in 2010. We have met our commitments under the United States Environmental Protection Agency-SIA PFC Emission Reduction Partnership to reduce emissions from the use of these gases with high global warming potential by 10% below our 1995 baseline. Overall we have reduced our emissions of PFCs by 87% since 1995. The small quantities now emitted are projected to remain at about this level in the foreseeable future. See the breakdown by type of PFC in the data dashboard.

About our GHG emissions data

We calculate our GHG emissions according to the GHG Protocol of the World Business Council for Sustainable Development and the World Resources Institute. In this section, we report HP's scope 1, 2, and 3 GHG emissions1 arising from HP's operations, automotive, and air fleet, and employee business travel:

  • Scope 1 emissions include those from the direct use of natural gas, diesel, refrigerants, and PFCs at operations, and from fuel used by HP's automotive and air fleet.
  • Scope 2 emissions are from purchased electricity.
  • Scope 3 emissions result from employee business travel by commercial airlines and rental cars. In other sections, we also report estimated scope 3 emissions from product manufacturing by suppliers, product transport, and product recycling (which has a net GHG emissions benefit).2

Data related to HP operations are based on our fiscal year (which ends October 31).

In 2010, we collected data from 269 sites (including all HP manufacturing sites and our largest office, warehouse, data center, and distribution sites). This accounted for 78% of our total floor space of approximately 7.3 million square meters. We extrapolated data from comparable operations, primarily data centers and office space, for the remaining 22% of floor space, unless stated otherwise.

We intend to continue to refine the process by which we collect data and calculate trends. In 2010, we began making our energy and water calculations quarterly to more accurately reflect changes to our real estate portfolio.

  2. 2 According to the U.S. Environmental Protection Agency's Waste Reduction Model (WARM) Tool, CO2e reductions from recycling are calculated per the following formula: 1.858 kg CO2e / kg recovered electronic waste.
