Promotion of Environmental Protection

Material Balance of the Central Glass Group

The Central Glass Group continues its efforts to reduce the environmental impact of production activities by carefully monitoring the amount of energy and resources used in our production activities as well as the environmental impact they generate. These efforts primarily focus on reducing emissions of greenhouse gases (hereinafter referred to as GHG) and discharge of environmentally hazardous substances into the air and water, as well as on recycling waste and reducing the final disposed amount. We will continue to monitor our resource consumption and amount of waste to further control generation, emissions and discharge of GHG, environmentally hazardous substances, and waste, as well as promote cyclic use to build a recycling-oriented society.

Material Balance (FY2022 Results)

Reduction of GHG Emissions

Medium- and Long-Term Targets

Reduce total Scope 1 and 2 GHG emissions for the entire Group by 40% from the FY2013 level by FY2030
Challenge to realize net-zero GHG emissions in 2050

GHG (Scope 1 and Scope 2) Emissions Result

In FY2022, we withdrew from the automotive glass businesses in United States and Europe and suspended the operation of some of the domestic glass furnaces, which led to the reduction to 332 thousand tons-CO2 (58% reduction from the previous fiscal year). We are planning to evaluate the feasibility of the 2030 targets after implementing a structural adjustment calculation of the amount of emission from the businesses that have already been sold.
We have included our policy to constantly reduce GHG emissions intensity in our Company’s materiality (priority issues), and achieved a reduction to 2.0t-CO2/million yen (47% reduction from the previous fiscal year) in FY2022.

We will continue to work on the reduction of GHG emissions and environmental impact throughout the Central Glass Group, including both at domestic and overseas affiliates in order to prevent global warming.

GHG emissions (Scope 1 and 2)

Reduction of Water Use

In the Central Glass Group, water use decreased in FY2022 due to the non-operation and periodic repairs of the flat glass manufacturing lines, which led to a year-on-year decrease in water intake intensity per sales.In FY2023, we are expecting to see a short-term increase in water intake due to an expected increase in water use following the reactivation of the flat glass manufacturing lines that underwent periodic repair; we will aim to decrease water intake intensity per sales in the medium to long term by proactively promoting the efficient use of water.

Water use

Reduction of the Final Disposed Amount of Industrial Waste

The Central Glass Group strives to reduce industrial waste.
In FY2022, the final disposed amount of industrial waste from our Company increased due to implementing the prior disposition of sludge. The final disposed amount of industrial waste from the domestic and overseas affiliates decreased; however, the one from our Group was 15,600 tons (23% increased from the previous fiscal year).
We will continue to work toward the reduction of final disposal amount through the promotion of emission reduction and recycling by reducing industrial waste generation and the use of plastics, as well as by implementing thorough sorting of waste.

Final Disposed Amount of Industrial Waste

Promotion of Industrial Health and Safety, and Security and Disaster Prevention

Promotion of Industrial Health and Safety

With the aim of ensuring the safety of workplaces, our Group has formulated the Safety and Health Management Policy, and conducts occupational health and safety activities at each business site in Japan and overseas.
In FY2022, our Company and domestic affiliates and business partners suffered a total of 27 occupational accidents, of which 6 cases were accidents that require time off from work and 21 cases were accidents not accompanied by lost worktime, with year-on-year decrease of 7 and 5 cases, respectively.
Our employees throughout the Group will continue to carry out activities to prevent work-related accidents and work on the promotion of industrial health and safety.

Lost time injury frequency rate
*Lost time injury frequency rate: (number of deaths or injuries resulting in lost work hours/total working hours) x 1,000,000
For the rate of lost time injuries in the manufacturing industry, we referred to the results of the 2022 Industrial Accident Trend Survey by the Ministry of Health, Labour and Welfare.

Promotion of Security and Disaster Prevention

Our Group has been working on the development of disaster prevention and security systems with the aim of reducing to zero the number of accidents including fire and explosion accidents, chemical spills, etc. However, we have seen an increase in the number of forklift-related accidents involving property damage in the last few years.
In FY2022, we strove to prevent such accidents by making opportunities for discussions on causes and countermeasures based on these accident cases, and continuing to implement skill training courses of forklift operation offered by a forklift manufacturer, while intensifying hands on training involving partner companies.
We will continue to make every effort to ensure not only safe working environments for our employees but also safe and secure local communities.

Addressing Climate Change Issues

1. Basic Approach

Climate change is one of the key issues to be addressed on a global scale in order to realize a sustainable society. Central Glass is working to contribute to the environment by providing environmentally friendly products and to reduce greenhouse gas (GHG) emissions through energy conservation and fuel conversion, as well as promoting research and development for the recovery and utilization of GHG.
In response to the recommendations of the TCFD (Task Force on Climate-related Financial Disclosures), as an enterprise, we seriously address the issue of climate change, promote efforts to address it, and strive to proactively disclose such information.

2. GHG Emissions Trends

Total 96.7 95.0 89.5 80.4 79.2 33.2

3. Disclosure based on TCFD recommendations


The Group's efforts to address environmental challenges and social issues, including climate change, are deliberated and resolved by the Management Committee, which is the decision-making body for business execution. We have established a Sustainability Committee for the purpose of analyzing and evaluating the status of efforts to address each issue across the organization. As appropriate, the Committee deliberates on individual policies and measures and reports and makes proposals to the Board of Directors on the results of these deliberations. The Board of Directors deliberates and supervises Central Glass's response to and progress in addressing environmental issues, etc., in response to discussions and recommendations made by the Management Committee and the Sustainability Committee.


We have assumed the following impacts on our business from risks and opportunities related to climate change.
We will continue to analyze scenarios to assess the impact of climate change risk on our businesses.

Risks Opportunities
Policy & Regulations Rising costs of energy and raw materials due to introduction of carbon tax and stricter CO2 emission reduction targets Basic unit improvements (cost reductions) by promoting the introduction of energy-saving technologies
Technologies Recovery of technology development costs to address decarbonization technologies Enhanced revenue opportunities through the development and sale of products that contribute to decarbonization (low GWP products, products that contribute to energy conservation, etc.)
Markets Detecting consumer behavior and needs, and responding in a timely manner
Reputation Market valuation through lack of promotion of decarbonization initiatives, etc. Improved market evaluation by promoting energy-saving technologies and products that contribute to decarbonization

Introduction of internal carbon pricing system

The Central Glass Group introduced the Internal Carbon Pricing (ICP) program in June 2023 as part of our efforts to achieve our GHG emissions (Scope 1 and Scope 2) reduction targets. This system uses an internal carbon price to visualize carbon costs and utilize them in capital investment decision making. The Central Glass Group will continue to promote investment in emission reductions to meet the growing demand for GHG emission reductions.
Reference: Internal carbon price (at the time of introduction): 10,000 yen/t-CO2

Risk management

With regard to risks related to business operations, each business unit identifies risks, evaluates their impact, and reports them to management as appropriate. The Sustainability Committee also shares business risks, opportunities, and countermeasures due to climate change and other factors across the organization, analyzes and evaluates them, and reports and makes proposals to the Board of Directors as necessary. In particular, for GHG emissions (Scope 1 and Scope 2), we began operating a mid- to long-term GHG Emissions Reduction Target Management Scheme from FY2023 to achieve the 2030 target and the 2050 target of zero net GHG emissions. This scheme estimates future emissions, evaluates the possibility of achieving the targets, formulates an action plan to reduce emissions, and revises the plan as necessary. It is positioned as an important process in the Group's GHG emissions reduction activities.

Indicators and Targets

  • We aim to reduce GHG emissions (Scope 1 and Scope 2) of the entire Group, including overseas, by 40% in FY2030, compared to the FY 2013 level.
  • Aiming for zero net GHG emissions by 2050.
