In recent years, the problems caused by climate change, such as extreme weather (droughts, heat waves, and heavy rain, etc.), as well as the increasing number of natural disasters, which were traditionally thought to occur once every 50 years, have been imposing serious impacts in many parts of the world. In addition to strengthening business continuity, companies are also required to take measures against climate change in terms of both mitigation and adaptation. In March 2020, we formulated our Long-term Vision of Global Warming Countermeasures, and are working to cut greenhouse gas emissions (scope 1 and 2*) from our business activities. We are also working towards SBT (Science Based Targets) certification, which is a mechanism for companies to set emission reduction targets consistent with the Paris Agreement.
Hamamatsu Photonics is conducting a range of energy-saving activities to achieve our medium-term target of reducing its energy consumption rate by 18% or more by FY2031 compared with FY2013.
In the fiscal year under review, we cut its energy consumption rate by 15.7 % in comparison with FY2013, outperforming its target of 7 % or more. We achieved this feat by implementing energy-saving measures in buildings and actively introducing equipment from the Top Runner system. Meanwhile, though carbon emissions increased 0.08 % against the previous fiscal year, that figure represented a 3.7 % incleased in carbon emissions per unit of net sales. In addition to taking measures against carbon-based energy sources, we continued to reduce its use of perfluorinated compounds (PFCs), sulfur hexafluoride (SF6) and other gases used in semiconductor manufacturing that are factors in global warming. We are achieving these reductions through the introduction of combustion and plasma abatement systems, which it began in FY2006.
We will continue to pursue efforts to reduce energy consumption and prevent global warming.
Hamamatsu Photonics is working hard to reduce carbon emissions by advancing the implementation of renewables such as solar and wind power. At Toyooka Factory, we have installed solar-power generating equipment (250 kW) on the walls and roof of No. 10 Building in collaboration with our solar power business. On the premises of the Central Research Laboratory, we combines solar-power generation with small-scale wind-power generation, in a hybrid solution for outdoor lighting. As of January 2020, we have implemented a cumulative total 404 kW of renewable energy.
In October 2018, we commenced purchasing of Chubu Electric’s “CO2-free Electricity,” expanding our introduction of renewables.

To grasp the environmental impact of the value chain*2, HPK is working on the calculation of Scope 3 (shown below) which is based on the Greenhouse Gas (GHG) Protocol.
Going forward, we will expand the calculation scope of Scope 3, improve accuracy, and strive to reduce emissions throughout the value chain.

Third-party Verification of greenhouse gas emissions based on ISO 14064-3
To provide and publish transparent and reliable information on the greenhouse gas emissions data calculated by Hamamatsu Photonics (scope 1, 2, and 3), we obtained third-party verification by SGS Japan Inc., and their written opinion. We will continue to work to improve the reliability of its data and reduce greenhouse gas emissions.
As part of its ongoing energy-saving campaign, Hamamatsu Photonics is advancing the visualization of its electrical-power use and striving to reduce peak power consumption. We publish on our intranet a Power Use Status Monitor, which displays demand and power consumption at each business location in real time. This resource plays a valuable role in each employee’s self-directed activities to save electricity.
The Revised Fluorocarbons Recovery and Destruction Law, which was drafted for the purpose of preventing global warming caused by leaks of GHGs substitutes, was enacted in April 2015.
We are promoting compliance with this law by assigning a control number to each relevant equipment and building an internal database for managing that equipment information and inspection records. In each division and business site, we conduct education activities covering laws and regulations as well as internal management methods for the administrators.

GHG used in semiconductor manufacturing such as PFC, SF6, and HFC have large global warming potential（GWP）. We are working to reduce its emissions by installing removal devices and optimizing processes.
