CO2 Emissions Reduction (Climate change measures)

Policy and Guideline

The Fujikura Group is working to reduce CO2 emissions as part of its key CSR measures for 2020. In addition, as medium-term targets for 2020, we have established detailed targets on the reduction of our total CO2 emissions in Japan and the reduction of CO2 emissions intensity outside of Japan. Furthermore, we have established the Fujikura Group Long-term Environmental Vision 2050 and a roadmap as long-term targets, under which we are promoting the challenge of eliminating CO2 emissions.

Aimed at achieving these targets, we are working from the two directions of using renewable energy and reducing energy usage through the promotion of investments in energy conservation and zero energy buildings (ZEB), among other measures.

Concept of the Base Year and Intensity Levels of CO2 Emissions

  • Fujikura Group's CO2 emissions are calculated by multiplying the energy usage amount by each type for each fiscal year by the CO2 conversion factor for each type of energy.
  • From FY2018, change to a calculation method based on the use of market standard emission factors indicated in the GHG Protocol Scope 2 guidance.
  • Base year
    - Japan: fiscal 2013
    - Overseas: fiscal 2014
  • Conversion factor
    - Electricity in Japan: FY2013-2017: Fixed use of actual emission factors for each electric utility in FY2013 announced by the Act on Promotion of Global Warming Countermeasures / FY2018: Adjusted emission factors for electric utilities for the most recent year announced by Act on Promotion of Global Warming Countermeasures
    - Electricity overseas: Fiscal 2012 emission factors announced by the IEA in fiscal 2014
    - Fuel inside and outside Japan: Emission factors for the latest fiscal year published by the Ministry of the Environment
  • For CO2 emissions overseas, we have established a uniform reduction target for the entire Group based on the basic unit per net sales

Total GHG Emissions and Energy Usage

Total GHG emissions in fiscal 2019 amounted to 401,000 tons, all of which were CO2. Emissions in Japan totaled 144,000 tons, while emissions outside of Japan totaled 257,000 tons.
Electricity accounted for 92% of energy used, with fuel accounting for 8%.

Calculating Emissions in the Supply Chain (Scope 1, 2 and 3)

Following the establishment of Scope 3 criteria in 2011, the GHG Protocol* requires companies disclose information on CO2 emissions not only for our own business activities but also for the entire supply chain. Fujikura continued to perform a simple calculation for all Scope 3 categories of the GHG Protocol in fiscal 2019. The calculation results for Scope 1, 2 and 3 from FY2015 to FY2019 are as follows.

  • **The Greenhouse Gas Protocol: A set of calculation standards for greenhouse gases created mainly by the World Business Council for Sustainable Development (WBCSD) and the World Resources Institute (WRI).

Activity Results for FY 2019

The Fujikura Group has joined RE100 and has formulated a roadmap for achieving the "Zero Challenge in 2050" for total factory CO2 emissions. As a measure to realize this, we have accelerated conventional activities based on two basic policies: (1) drastically reduce the amount of energy used by saving energy, and (2) the energy required for the business is covered by renewable energy.

The "Energy Conservation Promotion Team" and "Renewable Energy Promotion Team" have been set up in the New Energy Strategy Working Group in which representatives of all Fujikura Group companies and domestic manufacturing bases participate to promote activities by formulating plans and regularly checking progress.

Fujikura saw its CO2 emissions decrease 18.9% compared to the base year of fiscal 2013 because total emissions amounted to 81,000 tons due to adjusting the optical fiber production at the Sakura Works and Suzuka Works.
We will continue to actively promote energy-saving investments such as improving production efficiency by speeding up production lines, updating air-conditioning equipment in offices and clean rooms, updating factory utility equipment to energy-saving types, switching to LED at factory mercury lamps and office lighting.

In addition, our headquarters and R&D center switched electricity to hydroelectric power, reducing CO2 emissions by around 2,686 tons annually or 3.0% of total emissions. The headquarters building now produces net zero CO2 emissions associated with energy usage. Also installed solar panels in the "Kiba Millennium Forest" adjacent to the head office and are using the generated power for the circulation pump of the pond.

In the domestic group due to changes in production, resulting in CO2 emissions totaling 63,000 tons, which is 5.9% decrease the base year of fiscal 2013.
Furthermore, we are promoting energy saving by improving the power factor of power receiving and transforming equipment, reducing air conditioning power in clean rooms, reducing factory air leaks, updating air conditioning equipment, and switching to LED factory lighting.

As a result of these initiatives, the four Group companies were named Excellent Energy-Saving Companies (S class) by the Agency for Natural Resources and Energy per the Class Ranking Based on Energy-Saving in Factories and Workplaces Law Bulletin (FY 2019edition). In addition, our company has been evaluated for the fifth consecutive year.

The Group’s CO2 emissions outside of Japan decreased to 257,000 tons, but the CO2 emissions intensity was Deteriorated 6.5% compared to last year thanks to decreased in sales and other areas.

Activities in Transportation and Logistics

Our target was to lower energy intensity associated with logistics activities by 1% compared to the previous fiscal year (41.1 KL/kilotons). The actual figure was 38.3 KL/kilotons, beating the target. Increased shipments of domestic metal cables contributed to improved loading rates.

In addition, we continue to promote the efficient use of resources and are moving ahead with the reuse of packaging material and wooden drums. Moreover, we are now actively using the two-level loading jig developed to increase load factor (official name: power cable drum pallet).

Energy Conservation Initiatives

Promotion of Ministry of the Environment Campaigns

As a group of companies that is mindful of the environment, the Fujikura Group participates in the COOL CHOICE campaign for preventing global warming ahead of 2030 being implemented by Japan’s Ministry of the Environment. We are implementing active initiatives under this campaign. In addition, we also participate in the energy conservation and Cool Biz campaigns in the summer and Warm Biz campaign in the winter.

Promoting to the Switch to LED Lighting

The Fujikura Group is promoting the use of LED lighting. At the Suzuka Works, all mercury lamps for ceiling lighting in the factory have been switched to LEDs. Looking ahead, we will continue to changeover from mercury to LED lighting systematically ahead of the 2020 regulations following the conclusion of the Minamata Treaty on Mercury. At the same time, we will transition to LED bulbs mainly in ceiling lighting to save electricity and lower CO2 emissions.

Energy Conservation Initiatives at Business Sites

The Sakura Works, implemented energy saving through efficient operation and renewal of clean room air conditioning equipment and exhaust gas treatment equipment for optical fiber production. In addition, at cable factories, we are working to improve productivity and save energy by converting UV lamps used in production equipment to LEDs. The real estate company is promoting the use of LED lighting for tenant offices, and is promoting energy saving in collaboration with tenants by enhancing the functionality of BEMS.

Energy Conservation Initiatives at Group Companies

At a manufacturing site in the Kingdom of Thailand, we have begun purchasing electricity generated by mega-solar power plants floating in a reservoir adjacent to the factory. In addition, each base is proceeding with the conversion of lighting to LED, the upgrade of air conditioning equipment to the energy-saving type, and the upgrade of production equipment to the energy-saving type of large drive motors.
