The Yokogawa Group has set a long-term greenhouse gas emissions target for the year 2030 based on the 2° C target defined in the Paris Agreement.
Also, for the group companies in Japan, we have set CO2 emission reduction targets for the phases 2010-2014, 2015-2019 and 2020, and are implementing emission reduction programs to achieve those targets. Our ongoing CO2 emission reduction programs include the improvement of production lines, the introduction of high-efficiency heating/cooling equipment, the installation of inverter-driven lights, LED lights and the use of green power.
For our offices and factories, we have employed "InfoEnergy," Yokogawa's proprietary energy conservation support system designed to visualize energy data, in order to reduce CO2 emissions.
Moreover, in order to optimize global distribution, we are making efforts to improve transportation efficiency by changing the design of container boxes to reduce the weight, downsizing them, and revising transportation methods and routes for product shipment.
Yokogawa Electric and Yokogawa Manufacturing participate in the Keidanren's Commitment to a Low-Carbon Society (an industry action policy established subsequent to the first commitment period of the Kyoto Protocol). Specifically, the companies are working on improving their production processes in order to realize greater energy efficiency in production processes, such efficiency being a common goal of the electrical and electronics industry. (Our target is to improve the average annual energy consumption rate by 1% by 2020.)
Through strategies designed to reduce energy consumption and our active use of renewable energy sources, we aim to accomplish our greenhouse gas emissions target for the year 2030.
Greenhouse gas emission reduction target for 2020 and 2030
The Yokogawa Group (Japan) has set its CO2 emission reduction targets toward 2020, and is directing its efforts to achieve the targets. By using the annual average of emissions measured over the 2005 to 2007 period as the baseline (56,560 tons of CO2), we have set different reduction targets for three phases with the ultimate objective of achieving the goal set for 2020 and are promoting activities for the targets. Specifically, we are implementing a range of activities to achieve the reduction targets described below:
The Yokogawa Group (Japan) produced 34,425t-CO2 of carbon dioxide emissions in 2017, achieving its CO2 emission reduction target. The average reduction rate in the second phase was 39% against the target of 18%, achieving the target level evaluation in a single year for the second consecutive year. The target level was achieved as the evaluation of a single year. Overseas, each of our group companies overseas sets its voluntary reduction target and is working to achieve the target.

In addition to the direct CO2 emissions generated from our use of fuels and manufacturing processes (Scope 1) and indirect CO2 emissions generated through the use of purchased electricity, heat and other sources of energy (Scope 2), we also track and calculate other indirect CO2 emissions (Scope 3).

Komagane Factory promotes energy saving using waste heat in an effective manner. Heat is collected from heated water generated in the factory with a heat pump and is used for various other purposes. From 2015, we collect heat from the cooling water for air-conditioning systems and use it to heat raw water for producing ultrapure water. In 2016, we started to collect heat from heated water after cooling manufacturing equipment, and use it in an air reheating process.
With these heat reuse applications, the amount of LPG used decreased significantly compared to that before using waste heat management. The annual reduction is expected to be equivalent of 130 kiloliter oil.
