Prevention of Global Warming

We reduce use of energy
and emission of greenhouse gas.

Pioneer is addressing the global worming problems based on the basic concept which corporation shall fulfill the social responsibility for sustainable development. We think the risk and opportunity by climate change is management issue, recognize our standing position, and address from 2 viewpoints of production process efficiency (energy saving) and supply chain (indirect area).

Emission amount of the greenhouse gas at Pioneer group sites on March 2020 reduced 22% compared with previous year.

In order to reduce the CO2 emission amount in entire products lifecycle, we conduct LCA (life cycle assessment), analyze the CO2 emission amount, and conduct visible management to confirm reduction of emission amount compared with previous products, to address to prevent the global warming.

Analyze the CO2 emission amount in lifecycle

  1. Raw material
  2. Production
  3. Distribution
  4. Use
  5. Scrap

The target value of global warming countermeasures at sites proceeded by Pioneer has been established by considering various promises with stakeholders. Large-scale sites promote activities based on the frameworks of Energy Saving laws, and some sites focus on global warming countermeasure proceeded by local government.

Kawagoe Plant participates the Cap-and-Trade Emissions Trading System of Saitama Prefecture, takes reduction activities for the reduction target specified for production industry, then achieves the target by not using the emissions trading.

The third party verification: When reporting about the Cap-and-Trade Emissions Trading System of Saitama Prefecture, Kawagoe Plant had the third party verification for the greenhouse gas emission amount by the registered verification organization about 1st planning period of standard year and from H23 to H26, and the 2nd planning period from H27 to R1. Based on the verification guideline of Saitama Prefecture about the emission amount, boundary, measuring point, evidence of energy use amount were confirmed, and transparency and reliability of the data can be confirmed.

Introduction of Renewable Energy

Electric power makes up 83% of the energy use of the Pioneer Group. (result on March 2020) Most of the power is purchased from power companies. Considering about the greenhouse gas emitted at the time of power generation, electric power quality should also be taken into account. In regard to the introduction of renewable energy in Japan, solar power generating equipment for 30 kW has been installed at the Kawagoe Plant (Saitama prefecture).

Reduction of the greenhouse gas by review
and change the operation of clean dry air supply machine

Energy Saving Subcommittee in Tohoku Pioneer Yonezawa Plant takes activities by working style with various divisions under the leadership of facility department about the theme of energy reduction in business activities. The Energy Saving Subcommittee focused on efficiency of operation time of the clean dry air supply machine used at production site. When the clean dry air supply machine stops once and restarts, recovering to supply low dew point air, which is necessary for production, takes 4 hours or more, so production schedule needs to be grasped in detail. But by establishing frameworks to adjust with each related division in detail, operation stop in appropriate timing became possible. By this effort, 182.3 MWh electrical power can be reduced, it is reduction effect of 95.3 t-CO2 by conversion to CO2. By leadership of Energy Saving Subcommittee, Tohoku Pioneer Yonezawa Plant makes effort to optimize work processes to reduce the greenhouse gas emission cooperating with related divisions.
