Cutting GHG Emissions to Ensure a Global Temperature Rise of Less than 2℃
The Paris Agreement, adopted in December 2015, set out a long-term, shared worldwide goal of limiting the average global temperature increase to less than 2℃ over pre-Industrial Revolution temperatures (hereafter referred to as the 2℃ target), as well as the goal of carbon neutrality (zero real emissions) by the second half of this century. Correspondingly, moves aimed at achieving a decarbonized society have been accelerating on a global scale.
The Task Force on Climate-related Financial Disclosures (TCFD) was established in December 2015 by the Financial Stability Board, which includes participants representing central banks, financial regulatory authorities and finance ministries from major countries. The TCFD requests companies to use climate scenarios such as the 2℃ target to evaluate the climate-related risks and opportunities to their business and to assess and disclose the financial impact. Various international initiatives have also been launched, such as Science Based Targets (SBT), which calls for corporate emissions reduction goals designed to meet the 2℃ target, and RE100, which calls for companies to source 100% of the electricity they use from renewable energy. Furthermore, CDP（*1）, which runs the global disclosure system for investment that takes into account Environmental, Social and Governance (ESG) factors, requests that companies reduce GHG emissions by at least 2.1% year-on-year through voluntary efforts.
An international not-for-profit organization providing the only global system for companies and cities to measure, disclose, manage, and share vital environmental information. CDP works with major institutional investors around the world to encourage companies to disclose their impact on the environment and natural resources and to adopt measures that mitigate the impact.
GHG Reductions are a Critical Issue for the Fujitsu Group
The Fujitsu Group, as an entity with global operations, is fully aware that climate change is a serious worldwide issue that spans national and regional boundaries. For example, disasters triggered by climate change can disrupt procurement, logistics and energy supply networks, which in turn interrupts the process of supplying materials and energy to business sites. Regulations governing GHG emissions have an impact on the development and production of products and services, and any delays in responding to requirements can lead to lost business opportunities.
Since launching the Fujitsu Group Environmental Action Plan, we have treated the reduction of GHG emissions as a critical issue and worked to achieve the defined targets.
Most of the GHG emissions generated by the Fujitsu Group derive from purchased electricity, not from the combustion of oil or gas. Advances in 5G technology will lead to the expansion of cloud computing, IoT and mobile communications, thereby spurring increased power consumption in data centers, and this growing trend is expected to continue. We are therefore focusing on reducing power consumption by conducting energy conservation audits and regular power usage checks in our data centers, as well as in our factories and production lines in Japan and elsewhere.

Focusing on Enhancing Data Center Efficiency and Expanding the Use of Renewable Energy
Fujitsu joined and registered for SBT and RE 100 relatively early compared to other companies in Japan. We specified our medium- to long-term targets with SBT as “to reduce GHG emissions from our business sites by 33% by FY 2030 and 80% by FY 2050 in comparison to FY 2013”, and with RE100 as “to set a target to source 100% renewable electricity by 2050, with an interim target of 40% by 2030. In the Fujitsu Group Environmental Action Plan (Stage IX), we have set targets and measures based on these medium- to long-term targets.
The Fujitsu Group Environmental Action Plan (Stage IX) stipulates that we will “reduce greenhouse gas (GHG) emission from business sites by more than 14% (compared to FY2013) and reduce GHG emission by 2.1% year-on-year through voluntary efforts”. During the past two years, our voluntary efforts have led to GHG emission reductions in excess of 2.1% over the previous year. However, this improvement is primarily due to gains at specific facilities. To continue this positive trend it is crucial to enhance the power usage effectiveness (PUE) at data centers and to expand the use of renewable energy. In addition to conventional approaches for local cooling using aisle capping, we plan to further reduce power consumption in our data centers by boosting the efficiency of air conditioning equipment through the AI-controlled introduction of external air. Furthermore, we will deploy real-time visualization of the biased heat distribution in our data centers, not only in Japan but also elsewhere, and ensure appropriate heat distribution by optimizing the temperature of air supplied from the air conditioners and by adjusting fan speeds. In terms of renewable energy, Fujitsu intends to boost purchases of renewable energy certificates, after considering relevant regional characteristics and the economic feasibility, and to implement more on-site renewable energy capacity. Use of the Fujitsu Group’s leading-edge technological expertise in areas such as blockchain technology will also contribute to the spread and expansion of renewable energy.
