Management Structure

At Hochiki, TCFD Promotion Subcommittee under ESG Management Subcommittee leads the development and implementation of measures to address environmental issues, including climate change.


This ESG Management Subcommittee is held quarterly and oversees KPI progress management and policy direction based on reports from the subcommittee. The outcomes of discussions by the Subcommittee are reported to the Sustainability Strategy Committee, which reviews them and makes decisions from a management perspective. The final outcomes of deliberations are reported to the Board of Directors, which promotes company-wide environmental initiatives under its oversight framework. 

 

Compliance with RoHS Directive*

Electrical and electronic products manufactured by Hochiki fall under the "monitoring and control instruments" RoHS Directive category. We have reviewed our frameworks for product design, production line, inspection, analysis, and so forth in time for the application deadline, and have achieved full compliance with the RoHS Directive for our products sold by Hochiki Europe (UK) Limited and Kentec Electronics Ltd. to EU and UAE markets.


Hochiki will press on with its efforts to achieve compliance with the RoHS Directive for Hochiki brand products (electric and electronic devices) sold not only to EU markets but everywhere else in the world as well. 

*RoHS Directive: Directive that limits the use of hazardous chemical substances (six substances, including lead and mercury) in electric and electronic devices in EU member states, incrementally enforced since July 2006. For the "monitoring and control instruments" category, the Directive is applied to products sold in EU member states from July 2014 onward. 

Aquisition Rate of Environmental Management System Certifications

Across our group, 71.4% of production sites are certified under ISO 14001.

Climate Change Initiatives

 
Basic Approach

In recent years, the issue of global warming has intensified, and severe weather has been causing natural disasters all over the world. With the impact of global warming expected to become even more widespread in the coming years, long-term and concrete measures are in order.
We support the long-term goals of the Paris Agreement and the Japanese government’s policies aimed at achieving carbon neutrality, and complies with applicable laws and regulations, including the Act on Promotion of Global Warming Countermeasures and the Act on the Rational Use of Energy. We also ensure that our activities are aligned with the goals of the Paris Agreement and take a consistent approach to climate change mitigation and adaptation across our sites in Japan and abroad.

 
Hochiki is a supporter of TCFD Recommendations 

The HOCHIKI Group has incorporated ESG elements into its medium-term business plan GLOBAL VISION 2030 as before, and has listed the environment as one of its key material issues. We announced our support of the TCFD Recommendations in June 2022, and are committed to disclose our information even more robustly in accordance with its four pillars TCFD Recommendations: governance, strategy, risk management, and metrics and targets.

The HOCHIKI Group will continue its work to enable environments where each and every person can be and feel safe to live their everyday lives, and to build a sustainable society. 

TCFD-Recommended Disclosures

We disclose climate change-related information, according to the following four pillars of the TCFD Recommendations.

Based on the TCFD framework, we collect and analyse data on the impact the risks and profit-making opportunities related to climate change may have on our business activities, profits, and other aspects; identify risks and opportunities; and verify the resilience of our strategy through scenario analysis. The current status is as follows.

Metrics and Targets

The metrics and targets used to assess and manage relevant climate-related risks and opportunities.

Governance

Hochiki established its ESG Management Subcommittee to drive forward its efforts to tackle climate change. The Subcommittee examines and deliberates basic policies, critical issues, risks, opportunities, and other matters related to climate change. Details of these deliberations are reported to the Board of Directors every quarter, and targets, progress, and other aspects are monitored to ensure supervision over climate change risks. Decisions made by the Board of Directors are shared with relevant divisions and group companies, and reflected to their respective management plans and business operations. 

  

Strategy

The Company referred to the climate change scenarios (below 2C scenario and 4C scenario) of the IEA (International Energy Agency) and IPCC (Intergovernmental Panel on Climate Change), and conducted a scenario analysis to consider the long-term influence on the Company up to 2050. The outline of the influence on the Company's businesses is as follows:

Major risks and opportunities concerning climate change
Risk Management

Hochiki's Risk Management and Compliance Committee was established to help the company take control of and effectively manage risks across the HOCHIKI Group.

There are two kinds of climate change risks: transition risks and physical risks. Transition risks are risks related to market changes and the tightening of policies and regulations needed to achieve a carbon-free society. Physical risks are risks related to the acute and chronic changes brought about by global warming.


Climate change risks are mainly deliberated by the ESG Management Subcommittee and its subsidiary, the TCFD Promotion Subcommittee. The two committees analyze the risks, draft and promote measures, and manage progress, among other things.
Going forward, the ESG Management Subcommittee and Risk Management and Compliance Committee will work together to build a company-wide framework for risk management. 

 

Metrics and Targets

In view of global warming becoming a threat for the whole society, for Scopes 1 and 2 (business activities of the Company itself), the Company sets forth the objectives to decrease CO2 emissions by 2030 by 30% from 2019, and decrease the same to substantially zero in order to create a carbon neutral society by 2050.

 

Resource-Saving Through Renewable Energy

Hochiki has switched 100% of purchased electricity to renewable energy at its two domestic production sites, with the Machida Office beginning in February 2025 and the Miyagi Office in April 2025.

The Miyagi Office has been using wind and solar power generation facilities since June 2009 to supply electricity for production activities and reduce greenhouse gas emissions.

Miyagi Office

Resource Conservation Initiatives

We promote initiatives for resource conservation to ensure the effective use of finite resources, reduce environmental impacts, and support the realization of a sound material-cycle society. Along with optimizing product design and production processes, we will promote recycling to reduce waste and make effective use of water resources, aiming to balance business activities with environmental conservation and help realize a sustainable society. 

Waste Reduction

*1. Enforced on April 1, 2022, this Japanese law promotes resource circulation across the entire lifecycle of plastic products, from design and manufacturing through disposal and recycling, and advancing "3Rs (Reduce, Reuse, Recycle) plus Renewable". The law aims to contribute to solutions for marine plastic pollution, climate change action, and the transition to a sound material-cycle economy.

*2. A hot runner system is a structure that keeps resin heated up to just before the product cavity and allows the molded product to be removed after it is cooled and solidified. Compared with cold runner systems, it reduces resin usage and offers advantages including lower material loss and shorter cycle times.

Policy

We are committed to reducing waste through the effective use of resources in product design and production processes, preventing pollution, and helping realize a sound material-cycle society.

Waste Seperation and Recycling

We promote recycling by thoroughly breaking down waste and ensuring proper separation prior to disposal.At our production sites, we have set goals for recycling waste into resources to promote the effective use of resources.

Hot Runner System

The Act on Promotion of Resource Circulation for Plastics*1, enforced on April 1, 2022, calls on waste-generating businesses to reduce plastic use and advance resource circulation. Hochiki has introduced a hot runner system*2 in injection molds for selected detectors and bases to reduce runner waste and thereby reduce resin (plastic) waste in the manufacturing process.
