Addressing the ICMM’s Performance Expectations (PEs)

ICMM, of which JX Nippon Mining & Metals is a member, requires its member companies to conduct PEs*, a program to verify each company’s progress in achieving the roles and results expected of the mining and metals industry. In response, the Group conducted a self-assessment of its corporate office and seven sites. The following is a summary of the assessment results.
Of the sites for which self-assessment was conducted, we plan to undergo third-party validation at the Saganoseki Smelter & Refinery and Hitachi Works, both of JX Metals Smelting Co., Ltd., as well as the Caserones Copper Mine. This is due to their high quantitative importance in terms of elements such a business scale and production volume.

*

Performance Expectations (PEs) is a program to evaluate companies’ achievement of requirements in the ICMM’s Mining Principles and Position Statements. Self-assessments and third-party Validations are required for subject sites. Self-assessments are scored on a three-point scale: Meets, Partially Meets, and Does not Meet

Energy Consumption

*

Energy consumption is calculated by applying the calorific value conversion coefficients for fuel and electricity as stipulated in the Act on the Rational Use of Energy (Energy Conservation Act). (9.97 MJ/kWh or 9.28 MJ/kWh is applied for purchased electricity)

Water Resources

Water Usage^*1

Water Discharge Volume^*2

Total Water Usage^*1

Total Water Discharge^*2

*1

Seawater usage at the Saganoseki Smelter & Refinery of JX Metals Smelting Co., Ltd. is calculated based on pumping capacity.
Freshwater usage at the Saganoseki Smelter & Refinery of JX Metals Smelting Co., Ltd. and water usage at other operating sites are based on flowmeter readings or on invoices from the site’s respective water utility.

*2

The volume of water discharged into public waters (oceans and rivers) at each operating site represents the following: an amount calculated based on drainage weirs (Hitachi Works, Isohara Works, JX Nippon Tomakomai Chemical Co., Ltd., and JX Nippon Mikkaichi Recycle Co., Ltd.); an amount obtained by multiplying groundwater usage by a fixed rate (Kurami Works, Toho Titanium Co., Ltd.’s Chigasaki Plant); an amount from invoices (Toho Titanium Co., Ltd.’s Yahata Plant and Kurobe Plant); or an amount based on flowmeter readings (other operating sites). The volume of water discharged into the sewage system at each operating site represents the following: an amount calculated based on daily water discharge (TANIOBIS Co., Ltd.); or an amount based on flowmeter readings or on invoices from the site’s respective sewage utility for other operating sites.

Totals are for operating sites subject to legal requirements (sites that discharge water into oceans).

BOD Load

Totals are for operating sites subject to legal requirements (sites that discharge water into rivers or streams).

Climate Change

CO₂ Emissions From the Entire JX NMM Group (Scope 1 & 2)

*

Scope 1 emissions are those from energy consumption (fuel), emissions from incineration of waste materials (waste oil, waste plastic, sludge, waste wood), and emissions from reducing agents, neutralizing agents, graphite electrodes, and recycled materials, converted to equivalent CO₂.

*

Scope 2 emissions are those from electricity consumption converted to equivalent CO₂.
Emissions from electricity consumption include those from thermal energy (consuming steam, hot water, cold water) supplied by third parties. The emission factors applied for Scope 2 calculation are as follows for domestic and overseas Group operating sites, respectively.

The Domestic:

The latest adjusted emission factors per electric power utility published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry are applied

Overseas:

Emission factors published by local power companies, national governments, or country-specific emission factors published in the IEA Emission Factors 2021, issued by the International Energy Agency (IEA), are applied

Waste Materials and By-Products

Volume of Final Disposal of Waste

*

These do not include the approximately 27.0 million tons of slag from the Caserones Copper Mine.

*

The volume of final disposal of waste has increased rapidly due to the inclusion of Toho Titanium Co., Ltd.’s offshore landfill volume and final disposal volume of the TANIOBIS Group in calculations, as of fiscal 2020.

Total Discharge Volume by Type of Waste Materials

*

Total emissions increased because slag, which had been reused as valuable resources, is now treated as waste.

By-Product Production

Chemical Substances

Volumes of Release and Transfer of PRTR Substances

The values given are the total amount reported by operating sites subject to reporting requirements under the PRTR Act. (the domestic companies defined in Scope of this Report on page 3 as Environment section reporting).
Of the 49 chemical substances subject to reporting, those totaling at least 5.0 tons in any category, and dioxins, are listed here.
There were no cases of chemical substances released into the soil.

Occupational Health and Safety

Occupational and Other Accidents^*1,^*2

*1

Safety performance data is compiled on a calendar year basis (January to December).

*2

The number of casualties presented in this table includes work-related illnesses such as back pain and heat stroke.

*3

Until 2019, data included the Company and other Group companies (excluding Toho Titanium Co., Ltd.); however, from 2020, Toho Titanium and subcontractors have also be en included in the scope of aggregation, and data has been retroactively revised to 2019. Note that frequency and severity rates are excluded.

*4

Each accident category is defined as follows.

• Fatalities: Worker deaths resulting from work-related causes.
• Occupational accidents with severe consequences: Accidents resulting in more than six months of lost work days or a disability grade.
• Accidents with lost work days: Accidents requiring one or more days of absence from work for the purpose of examination, treatment or recuperation. These shall in principle be at a physician’s discretion. Note that this excludes “Occupational accidents with severe consequences.”
• Accidents without lost work days: An accident that does not require one full day or more of absence from work as diagnosed by a physician, and in which the affected worker is able to go to work after the accident.

*5

Incidences related to the cause of the injury or illness, based on “Types of Accidents,” published by the Ministry of Health, Labour and Welfare.

*6

Both the frequency rate (the number of persons harmed or killed due to occupational accidents per million cumulative actual work hours) and the severity rate (number of work days lost per thousand cumulative actual work hours) had only covered Company employees until 2019; however, as of 2020, these figures cover Company employees and employees at other Group companies (including Toho Titanium Co., Ltd.). Note that cumulative working hours are calculated based on the hours reported from work sites with production facilities (operations divisions) and major offices such as the head office, including some estimation in the figures.

*7

Safety statistics for subcontractor employees include not only those stationed permanently but also spot vendors. Note that these are subject to statistics for frequency rate and severity rate as of 2020. Here, cumulative work hours are calculated as follows: Number of permanently stationed subcontractor employees at the end of each month x number of operating days x 8 hours/day.
(Reference) In 2021, the frequency and severity rate of occupational accidents for all businesses in Japan were 2.09 and 0.09, respectively (Source: Ministry of Health, Labour and Welfare, “Survey on Industrial Accidents”)

*8

The Group defines a serious accident as one that results in four or more lost work days, and considers the occupational injury rate per 1,000 employees to be one of its key indicators for evaluation. (Occupational injury rate per 1,000 employees (four or more lost workdays) = number of casualties with four or more lost workdays ÷ total number of employees (including employees of regular partner companies) x 1,000)

*9

No physical injuries were caused as a result of explosions/fires.

*10

While this includes Group companies and subcontractors, this data should be used only for reference as it is difficult to conduct follow-up surveys and aggregate working hours for subcontractors at overseas operating sites, and detailed data such as frequency rates are not disclosed.
