Fujitsu Sustainability Report: CO2 Emissions Drop 7.3%

In 2011, Fujitsu Group’s global CO2 emissions totaled around 1.098 million tons, representing a year-on-year reduction of 7.3 percent, or about 87,000 tons, and an 18.2 percent reduction on levels from the company’s 1990 baseline year.

The Japanese corporation had a target of reducing its carbon emissions by 6 percent, from 1990 levels, by the end of 2012.

The group says it has been promoting an environmental burden reduction policy through the use of a green IT project called Green Policy Innovation. Since 2009 this project has cut 9.98 million tons of CO2 from the company’s emissions. This total comprised 2.11 million tons of reductions from eco-friendly ICT infrastructure products and 7.87 million tons from ICT “solutions” that contribute to reducing environmental burdens, the report says. The program is targeting a cumulative total of 15.17 million tons of CO2 reductions from 2009 to 2012.

The company’s Nagano, Japan, facility has installed Fujitsu’s first geothermal heat extraction system. Fujitsu plans to generate roughly 155W of energy per one-meter-long pipe using the system. This should reduce the plant’s fuel consumption by roughly 47 kiloliters of crude oil equivalent and its annual carbon dioxide emissions by about 120 tons compared with the former system, the report says. The system will be increasingly used at the Nagano site and Fujitsu is investigating implementing it at other sites.

Fujitsu’s water usage totaled 21,797 thousand cubic meters in 2011, up 0.8 percent from 2010, the report says. Recycled water accounted for 26.6 percent of the corporation’s water consumption in 2011. This is a slight reduction on 2010 levels which stood at 27 percent, the report says. Along with recycling and reusing service water, the company also harvests rainwater. Since 2007 – the earliest year the report provides figures for – the company has reduced its water use by just under 19 percent (see graph). below)

The company generated 28,448 tons of waste in 2011. This represents an 8.4 percent reduction on 2010 levels and a 27 percent reduction from 2007 levels. The group had targeted a 20 percent reduction in waste levels by 2012 over 2007 levels.

In August, the company announced that it had developed the PC industry’s first recycling system that collects the plastic from used CDs and DVDs for repurposing in the bodies of notebook PCs. Compared to conventional notebook PC manufacturing processes, this system should reduce the amount of newly produced plastic used by 10 tons per year and cut CO2 emissions by about 15 percent per year, Fujitsu says. It used the recycled plastic for part of the front panel of its LIFEBOOK P772/E notebook PC for enterprise customers, a model in its summer 2012 lineup.
