Greenhouse gas emissions

Add to my report Go to my report

HP is working to reduce our greenhouse gas (GHG) emissions by cutting our energy consumption from operations worldwide by 16 percent by 2010, compared with 2005¹. We report our GHG emissions according to the GHG Protocol of the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI).

GHG emissions from HP employee business travel are reported here. Product transport and employee commuting are not included in our GHG data.

	Performance

HP’s global GHG emissions from operations (not including employee business travel) decreased 5 percent in 2007, representing 82,160 tonnes of carbon dioxide equivalent (CO₂e). This was due to the dramatic drop in our natural gas use, a decrease in our electricity consumption and changes in manufacturing.    

Emissions per unit of floor space remained the same in 2007 compared with 2006, and emissions per unit revenue, a measure of overall efficiency, decreased by 17 percent.  

The sources of GHG emissions from HP operations in 2007 were:

• Electricity, 93.4 percent
• Natural gas, 4.2 percent
• Manufacturing emissions, 1.0 percent
• Refrigerant emissions, 1.4 percent

	Perfluorocarbons

Perfluorocarbons (PFCs) are gases used widely in the semiconductor industry for cleaning and etching processes. The global warming potential of PFCs ranges from 6,500 to 23,900 times greater than that of CO₂.

HP’s PFC emissions account for approximately 1 percent of our total GHG emissions. In the United States, HP participates in the PFC Reduction Climate Partnership, a voluntary initiative with the U.S. Environmental Protection Agency (EPA) to reduce specified PFC emissions by 10 percent from 1995 levels by the end of 2010.¹ HP achieved this target worldwide in 2006. In 2007, HP continued to reduce PFC emissions to less than 13,700 tonnes CO₂e, a 48 percent reduction from the 1995 baseline. 

See the breakdown by type of PFC in the interactive data dashboard.

¹ The EPA program goal was to reduce the annual absolute PFC emissions of the participating companies collectively by 10 percent on a tonne carbon equivalent (MTCE) basis below the 1995 baseline PFC emissions.
We report the emissions in tonnes CO₂e for consistency with the rest of the report. To convert to MTCE, divide
by 3.67.
