Reducing Greenhouse Gas (GHG) Emissions and Boosting Energy Intensity at Our Business Sites

Our Approach

The Fujitsu Group considers the prevention of global warming an important issue. We have, therefore, formulated our medium- to long-term environmental vision, the FUJITSU Climate and Energy Vision, and aim to eliminate all CO2 emissions from our business activities by 2050.

Among GHGs, our business sites (plants, offices and datacenters) primarily emit CO2 when energy (electricity, fuel oil, gas) is used, and perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3) during the semiconductor manufacturing processes. We are striving to decrease and control the volume of emission of these gases by complying with relevant laws and setting reduction targets.

Reducing CO2 Emitted During Energy Consumption

About 90% of the Fujitsu Group’s total GHG emissions arise from CO2 emissions due to energy consumption. Therefore, we continuously promote the following energy-saving measures to reduce CO2 emissions.

  • Appropriate operation of equipment, improvement in management, and energy-saving measures focused on motive-power facilities (introduction of free cooling, inverters and energy saving equipment, fuel conversion, etc.)
  • Increasing efficiency by reviewing the manufacturing process (innovations in production, development of green production technology)
  • Maintaining appropriate room temperature for office air conditioning, saving electricity used in lighting and office automation equipment
  • Measuring energy consumption for visualization and promoting use of the data so collected

Reducing Emission of GHGs Other Than CO2

As for GHGs other than CO2, the Fujitsu Group mainly uses perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3) at the semiconductor divisions. We are taking continuous steps to switch to gases with lower global warming potential (GWP) and install equipment to remove harmful gases in our new and existing production lines.

FY 2018 Performance and Results

Targets under the Fujitsu Group Environmental Action Plan (Stage VIII) Last fiscal year
(FY 2018 results)
Reduce GHG emissions by 5% or more (compared to FY 2013)
Improve energy intensity by an annual average of 1% or more
Reduced by 30.3%
Improvement of 1.1%

Promoting Reduction in CO2 Emitted During Energy Consumption

We continue to invest in energy-saving equipment (introduction and upgrade of BAT* equipment, mainly for air conditioning and lighting) and ensure their appropriate operation at the facilities at all business sites. We are also streamlining our production processes, saving electricity used for air conditioning, lighting and automation in offices, making energy consumption visible, and leveraging measurement data.

For instance, we improved facility operations (2,300 tons) at the Tatebayashi System Center by controlling the number of air conditioners, reviewing their operation, suspending operation of devices and taking other measures. We also reviewed the appropriateness of the position of production devices (980 tons) at Fujitsu Interconnect Technologies Limited.

As a result of these efforts, the total emission of GHGs in FY 2018 was about 923,000 tons (specific consumption/sales revenue: 218,000 tons/100 million yen), which is 30.3% less in comparison to FY 2013. Although part of this decrease is attributable to transfer of business and other factors, we also reduced another 25,000 tons or so through measures implemented.

The energy intensity improved to an annual average improvement of 1.1% from FY 2016 to FY 2018.
