Reducing Greenhouse Gas (GHG) Emissions at Our Business Sites
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) 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 2019 Performance
|Targets under the Fujitsu Group Environmental Action Plan (Stage IX)||FY 2019 Performance|
|Reduce GHG emissions of our business sites by 14% or more (compared to FY 2013)（*1）||Reduction by 24.7%（*2）|
|Through our own efforts, reduce GHG emissions by 2.1% or more compared to last FY||Reduction by 2.4%|
- （*1）Boundary : Business sites owned by Fujitsu and Fujitsu Group excluded MIFS※, and major data centers.
※ MIFS : Abbreviation of “MIE FUJITSU SEMICONDUCTOR LIMITED” (Currently “United Semiconductor Japan Co., Ltd.”)
- （*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, we improved facility operations (2,180 tons) at the Tatebayashi System Center by controlling the number of air conditioners, reviewing their operation, suspending operation of pumps and cooling devices, and taking other measures. Through our own efforts, we carried out measures to reduce our emissions by roughly 22,000 tons (2.4% 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 IX), by 24.7% in comparison to our emissions in FY 2013.
- （*3）BAT (Best Available Technologies): Usable state-of-the-art technologies to reduce GHGs.
- （*4）Environmental Action Plan (Stage IX) performance values for the reference year (FY 2013) and FY 2019 are the total values for business sites targeted by the Environmental Action Plan (Stage IX).
- （*5）CO2 conversion factors of purchased electricity are market standards in keeping with SBT for both the reference year (FY 2013) and FY 2019 performance values.
Total Emissions of 802 thousand Tons in FY 2019
Our total GHG emissions in FY 2019 were 802 thousand tons (output level per sales amount: 20.6 tons/100 million yen). They increased overseas due to boundary changes (additions of DC with management authority), but decreased by 13.1% in comparison to FY 2018 for reasons such as the business transfer of our semiconductor division.
- （*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 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, and 0.461 tons-CO2/MWh domestically and the latest IEA values overseas (by country) for FY 2019
- （*7）Emissions other than CO2: These are converted to equivalent amounts of CO2 using the global warming potential (GWP) for each gas.
Examples of Initiatives in FY 2019
Fuel Cell Power Generation System Introduced at the Kumagaya Service Solution Center
Fujitsu Frontech Co., Ltd. introduced and began the use of solid oxide fuel cells (SOFC), an environmentally friendly power generation system, at the Kumagaya Service Solution Center (Kumagaya City, Saitama Prefecture; hereafter, Kumagaya SSC). It is the first domestic example of fuel cells being introduced in the Fujitsu Group in japan.
The Kumagaya SSC provides services that require 24/7 operation, including outsourcing services for financial institutions and help desk services for distribution centers. As a result of examining the compatibility between BCP measures for major services and an environmentally friendly power supply, Fujitsu Frontech Co., Ltd. introduced Bloom Energy Japan, Limited’s fuel cell power generation system, which makes it possible to secure a stable power supply even in the event of power supply interruptions due to natural disasters, etc., and can reduce CO2 emissions.
By introducing this system, approximately 50% of the electricity consumed by the Kumagaya SSC can be covered by fuel cells, which is expected to reduce CO2 emissions by approximately 35% per year (in comparison to FY 2018), compared to a situation where all necessary electricity is procured from power companies.
Through the promotion of energy conservation and the use of clean energy, we will continue to reduce CO2 emissions and contribute to the continued development of the company, as well as the realization of a sustainable society and environment.
