Reducing Greenhouse Gas (GHG) Emissions 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 and offices, as well as datacenters) primarily emit CO2 when energy (electricity, fuel oil, gas) is used, and perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), sulfur hexafluoride (SF6) during the manufacturing processes and PFCs and HFCs from fluorocarbon leakage. We will set reduction targets in addition to complying with the relevant laws, and we are striving to reduce and control the volume of use and emission of these gases.

Reducing CO2 Emitted During Energy Consumption

About 99% 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, and switching to LED lighting
  • 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) and sulfur hexafluoride (SF6) at the manufacturing 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. We also carry out inspections and maintenance to comply with relevant laws regarding PFCs and HFCs emissions resulting from fluorocarbon leaks from air conditioning equipment.

FY 2022 Performance

Targets under the Fujitsu Group Environmental Action Plan (Stage X)FY2022 result
Reduce GHG emissions of our business sites by 4.2% or more every year (compared to FY 2013) (*1)10.5% reduction (47.5% reduction compared to baseline year) (*2)
  • (*1)
    Target organizations: Business sites owned by Fujitsu and the Fujitsu Group. Includes major data centers.
  • (*2)
    Reduction rate based on market standards

Promoting Reduction in CO2 Emitted During Energy Consumption

We continue to invest in energy-saving equipment (introduction and upgrade of BAT (*3) 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, as for investment in lighting equipment, we have continued to adopt high efficiency LED lighting and lowered CO2 emissions by 1,423 tons. Moreover, we also improved facility operations (7,532 tons-CO2) by reviewing air conditioner operating conditions, such as switching to higher efficiency equipment and controlling the number of units, and suspending operation of pumps and air conditioning devices. Through our own efforts, we carried out measures to reduce our emissions by roughly 13,000 tons-CO2 (2.6% in comparison to last fiscal year).

As a result of these initiatives, we reduced our GHG emissions according to market standards in keeping with SBT, which is an objective in the Environmental Action Plan (Stage X), by 10.5%pt compared to the baseline year (47.5% reduction in comparison to our emissions in FY 2013).

Environmental Action Plan (Stage X) GHG Emissions Reductions

  • (*3)
    BAT (Best Available Technologies): Usable state-of-the-art technologies to reduce GHGs.
  • (*4)
    Environmental Action Plan (Stage X) performance values for the reference year (FY 2013) and FY 2022 are the total values for business sites targeted by the Environmental Action Plan (Stage X).
  • (*5)
    CO2 conversion factors of purchased electricity are market standards for both the reference year (FY 2013) and FY 2022 performance values.

Total Emissions of 540ktons-CO2 in FY 2022

Our total GHG emissions in FY 2022 were 540 ktons-CO2 (output level per sales amount: 14.5 tons-CO2/100 million yen). They decreased by 13.1% in comparison to FY 2021.

Trends in Total Greenhouse Gas Emissions

  • (*6)
    CO2 emissions in Japan and overseas: The CO2 conversion factor for purchased electric power in performance reports has been calculated with a fixed value of:
    In Japan - 0.570 tons-CO2/MWh from FY 2013 to FY 2015, 0.534 tons-CO2/MWh for FY 2016, 0.518 tons-CO2/MWh for FY 2017, 0.497 tons-CO2/MWh for FY 2018, 0.461 tons-CO2/MWh for 2019, 0.444 tons-CO2/MWh for FY 2020, and 0.436 tons-CO2/MWh for FY 2022
    Overseas – Same coefficients as those used in Japan from FY 2013 to FY 2018, and the latest IEA values (by country ) for the relevant FY from FY 2019 onwards
  • (*7)
    Emissions other than CO2: These are converted to equivalent amounts of CO2 using the global warming potential (GWP) for each gas.
