6th Medium-Term Environmental Plan

Environmental Targets and Achievements

Through products and services, Sumitomo Heavy Industries Group (“SHI Group”) has promoted the 6th Medium-Term Environmental Plan
(FY2020 to 2023) since FY2020 in the aim of helping to resolve social issues, enhance corporate value, and contribute to realizing a sustainable
society. With a focus on the following four key issues in our 6th Medium-Term Environmental Plan, we have been working to reduce total CO2
emissions during product manufacturing processes to help mitigate climate change, as well as expanding our range of Sustainability Plus
Products (to reduce CO2 emissions during product use) as a part of our overall CO2 emission-cutting activities.

(1) Strengthen environmental risk management
We will strive to prevent environmental incidents and continuously improve and invigorate our environmental management system.

(2) Reduce CO2 emissions in a consciousness response to climate change

Of “the burdens that the product life cycle places on the environment”, we will endeavor to “reduce CO2 emissions” during both productmanufacturing and use, which comprise some of the highest environmental loads.
SHI Group has set the following medium- and long-term targets.
• Aim to achieve carbon-neutral (net zero CO2 emissions) throughout the entire SHI Group by 2050
• CO2 emissions during product manufacturing (Scopes 1 and 2*1): 50% reduction by 2030 (compared to FY2019)• CO2 emissions during product use (Scope 3*1, Category 11*1, 2): 30% reduction by 2030 (compared to FY2019)
In line with these targets, SHI Group is taking a more proactive approach that includes adopting renewable energies and installing solar power
generation systems in addition to our regular activities.

(3) Reduce the environmental loads of business activities

FY2022 Targets and Achievements
With the exception of environmental incidents and total CO2 emissions (Japan), SHI Group achieved 13 of our 15 targets in FY2022
as set out in the 6th Medium-Term Environmental Plan.
Environmental incidents: Although no severe environmental incidents occurred, six environmental incidents did occur. So, we did notachieve this medium-term goal.
•Of those incidents involving oil, chemical substance, wastewater, or other leaks from equipment, many were the result of physicalfactors such as equipment failure. Therefore, along with ensuring regular maintenance and patrols, planned repairs, and other efforts
to keep equipment efficient and reliable, we have reassessed our environmental training, work procedures, as well as revised andimplemented environmental risk assessments.
Other environmental incidents have also occurred due to paint dust scattering outside sites and damaging vehicles, in addition to filingincomplete notifications following revisions to relevant laws and regulations. We are continuing to strengthen systems at sites whereincidents have occurred to perform more thorough checks, expand these procedures to other sites, and thoroughly and continually
implement measures to prevent any recurrence of such incidents.
•Total CO2 emissions (Japan): Our business units implemented measures to reduce CO2 emissions and we achieved a 4% reduction
compared to FY2019 levels, but overall emissions fell only 2.3% compared to FY2019 due to further operational increases, utilizationof new plant building capacity, and other factors.
Information about other items is given on p.5 and after.
BenchmarkOf “the burdens that the product life cycle places on the environment”, we will work to “reduce the environmental footprint” associated with businessactivities other than “CO2 emissions” through such efforts as contributing to solutions for marine plastic pollution and implementing the 3R principle
for waste and product packing materials.

based on our own criteria. The results are reported at Executive &Operating Officers Committee meetings.

・Examination by General Manager, General Administration Group(as required)
In conjunction with environmental audits, the General Managerof the General Administration Group conducts a separate
examination and provides guidance to departments at the General
Manager’s discretion (such as departments that, in the previous
fiscal year, experienced an environmental incident, those whose
performance was far below targets, and other necessary
circumstances).
・Environmental management meeting (biannual)
Environmental Management Meetings are held for works andaffiliated companies in Japan to report activity results and shareproblems. China Environmental Management Meetings are also
held for affiliated companies in China, with the aim of raising thelevel of environmental activities engaged in at those companies.

Environmental Risk Assessments

SHI Group regularly conducts environmental risk assessments topreempt environmental incidents.
Additionally, if an environmental incident occurs, we takeappropriate action and conduct a thorough analysis of the incident
as part of our efforts to prevent any recurrence as well as similar
incidents involving comparable equipment or substances at othersites.
SHI Group operates in a way that bolsters prevention of potential
environmental incidents, which are events that may someday
trigger an environmental incident even though the event itself is notclassified as an environmental incident.

Climate Change Adaptation

Climate Change Adaptation
Among our strategies for reducing our environmental footprint across all business activities including product life cycle,
the top priority for the SHI Group has been to reduce CO2 emissions.
Promotion of Environmental Management

The SHI Group recognizes that responding to climate change is a
key challenge in our environmental management. The Environmental
Management Group conducts monthly supervision of results
produced by each business division and provides feedback to thosein charge. In addition, the results are reported to management threetimes a year at meetings of the Executive & Operating Officers
Committee. SHI Group divisions promote climate change adaptation
by mobilizing all personnel in their efforts, making sure their activities
are visible, and implementing activities to improve various processes
so as to more efficiently utilize energy.

Reduction of CO2 Emissions During Product
Manufacture

SHI Group’s CO2 emissions in Japan during product manufacture in
FY2022 were 2.3% lower than in FY2019, meaning that we did notachieve this target. We have been promoting energy-saving activities,
converting to LED lighting, updating antiquated equipment, andincreasing energy productivity. However, we were unable to reachour target due to the impact of new plant operations and otherexpansion of our business.
In FY2023, we will continue to update to more energy efficientequipment, improve our energy productivity, and engage in otheractivities that will reduce CO2 emissions. In addition, we will take amore proactive approach, reviewing once again CO2 reduction
measures and adopting renewable energies.

Renewable Energy Adoption

Promotion of Green Logistics

SHI Group has promoted adoption of renewable energies. Since 2020,
we have proceeded to install solar power generation systems on newroofs of SHI Group plants. In FY2022, an additional 2,200 kWh became
available for a cumulative capacity equivalent to 3,600 kWh. We arecontinuing to actively install systems both in Japan and around the world
to achieve our intermediate benchmark of a 50% reduction by 2030 incomparison to FY2019.
We have also planned purchases of renewable energies andreviewed these plans with a view toward expanding the scale of thesepurchases. Along with CO2 emission reductions of 1% annually througha variety of energy-saving measures, we are endeavoring to introduce
solar power generation systems chiefly for new buildings, striving toincrease the scale of our renewable energy purchases, and promoting
CO2 emission reductions with the aim of realizing carbon-neutral by
2050.

The SHI Group is endeavoring to eliminate waste and enhance
efficiency in product transport in order to reduce CO2 emissions. In
FY2022, we achieved our domestic target, achieving a 5.9%
reduce vis-à-vis our target of maintaining a level no greater thanthat in FY2019 per basic unit of shipping (t-CO2/weight). We willcontinue to improve and optimize load factors, effectively utilize
modal mixes, and engage in other efforts to reach our target.

Receipt of Agency for Natural Resources and Energy
Director-General's AwardIn FY2022, we received the Agency for Natural Resources andEnergy Director-General's Award, which is part of the Energy
Conservation Awards sponsored by the Energy Conservation Center
Japan, for Sumitomo Heavy Industries Himatex’s heat treating
furnace energy intensity and CO2 reduction efforts.
Promoting fuel conversion fromheavy oil to LNG for all heattreating furnaces used in theprocess of producing rolls formetal rolling improved energy
intensity by 15% compared to
FY2017 when this initiative had not
begun. This fuel conversion also
reduced CO2 emissions by 27%,
significantly contributing to the
reduction in emissions during
product manufacture.

The SHI Group has set and managed indices for emissions as well as
energy productivity (sales/CO2 emissions) as part of our efforts toenhance production efficiency and carry out activities aimed at reducing
CO2 emissions. For FY2022, we raised our target to a 3% improvement
over the FY2019 level for our activities, which we achieved with a 9.2%
improvement in Japan and a 9.6% improvement overseas.

In striving to reach our target of keeping the amount of waste(including hazardous waste) generated per basic sales unit in FY2022
at or below the average for the FY2017-2019 period, we achieved an
24.0% reduction. Converting shot blast chip refuse, which used to bedisposed of as industrial waste, into a marketable disposal, reusing
filtered test-run oil, and implementing other innovations led to a
reduction in emissions. In the future as well, we will promote waste
reduction with a particular awareness of the 3R principle, including
carefully separating waste and recyclable items.
Overseas, our activities advanced having set a 3% reduction below
the FY2019 level as the basic target unit, and we achieved a 18.6%
reduction in FY2022.

SHI Group will continue efforts to manage and reduce waste plastic
across the entire group. We will promote the 3Rs (Reduce, Reuse,
Recycle) plus Renewable for plastic packaging materials and consider
more in-depth actions that even look at product components in our aim toengage in operations with a full awareness of the supply chain.

Zero-Emissions (Landfill Rate Reduction)
The SHI Group defines a zero-emission plant in Japan as one forwhich the ratio of landfill disposal volume (landfill rate) to waste
discharge volume is less than 0.5%. Since FY2005, we have beenpromoting efforts to reduce the landfill rate. In FY2022, the landfill
rate for all domestic works (6 works and 7 plants) and groupbusinesses other than works (9 companies) was 0.1%. We haveconsistently achieved zero emissions since FY2011. Overseas, wherebusiness activities are carried out with a non-landfill target rate of atleast 95%, the target of 3% was achieved in FY2022, resulting in a
combined domestic and overseas waste landfill rate of 1.7%.
Recycling by separating waste is key to achieving zero emissions. In
the future as well so that we may maintain zero emissions, we will
meticulously separate waste as part of our aim to have our plants
contribute to a sound material-cycle society.

Since unnecessary water consumption was judged to have been
almost eliminated as a result of ongoing water consumption cuts, SHIGroup has continued to set a target of maintaining average water
consumption below the level of the previous Medium-Term Plan (2018to 2019) in the 6th Medium-Term Environmental Plan as well.
Our target was achieved in FY2022 of a 3.9% reduction compared to
the level set. We accomplished this by preventing leakage with the useof monitoring devices, and reducing water consumption by using
circulating water in test devices. We will continue to set our sights onachieving our target by working to eliminate waste. We also achieved
our target overseas with an 13.1% reduction in the basic sales unit ascompared to our target of maintaining water consumption at or below
the FY2019 level.

Prevention of Environmental Pollution

Biodiversity

We manage chemical substances to prevent environmental contamination.
Complete Elimination of Organochlorine Chemical
Use
Continuing to strive for completely elimination
We have continued to strive to completely phase out the use ofdichloromethane, tetrachloroethylene, and trichloroethylene, organic
chemicals subject to the Soil Contamination Countermeasures Act.
We have completely eliminated and banned the use of ozonedepleting substances HCFC-225 and HCFC141b since FY2008
and FY2010, respectively. We have been promoting the scheduled
replacement of R-22, production of which was discontinued in
FY2020.

Control of VOC Substance Emissions
Toluene, xylene, and ethyl benzene contained in paint solvents
account for at least 90% of VOC substances used by the SHI Groupin Japan. The 6th Medium-Term Environmental Plan has set a target
for these emissions to be maintained at or below the FY2019 level.
In FY2022 also, we achieved a 9.1% reduction below the FY2019
level. This was accomplished by adopting powder coatings,
employing low-solvent paints and VOC-free cleaning agents, as wellas improving painting efficiency to reduce paint consumption. In
addition, we also achieved a 18.8% reduction in the basic sales unit.
We will continue to reduce emissions by expanding the scope
applicable for low-solvent paints and VOC-free cleaning agents aswell as powder coating, and cutting paint consumption throughfurther improvements in painting efficiency.
Additionally, our overseas activities to control VOC substanceemissions began in FY2012. Under the 6th Medium-Term
Environmental Plan, a target has been set for our overseas
companies of maintaining the basic emissions unit at or below the
FY2019 level.

Tanashi Hasso-no-Mori (Forest of Ideas)

PRTR Substance Emissions and Transfer Volume
The paint solvents toluene, xylene, and ethyl benzene comprise
90% or more of all PRTR substances. The 6th Medium-Term
Environmental Plan has set a target for emissions and emissions per
basic unit to be maintained at or below the FY2019 level. In FY2022,
we achieved a 7.2% reduction compared to FY2019. In addition, we
also achieved a significant reduction of 18.1% per basic unit of sales.
While maintaining quality, we will expand the application of lowsolvent paints and establish and expand solvent recovery and removal
equipment as part of our efforts to reduce emissions and transfer
volume.

Tanashi Works has preserved the Musashino Forest, which
occupies approximately 30% of the site’s area. A section of thisforest, which is home to over 4,500 trees of some 40 species, hasbeen named Hasso-no-Mori or the Forest of Ideas and opened to
the general public. This is a place where people may come andrelax. The space serves many functions, including a community
disaster prevention base and the object of academic research into
biodiversity.

SHI Group Participation in the Mt. Fuji Reforestation
Project
The SHI Group has joined OISCA Japan, through which we areparticipating in the Mt. Fuji Reforestation Project. The aim of thisproject is to revitalize the man-made forest of Mt. Fuji, which hassustained considerable damage from insects, and turn it into a
biodiversity-rich forest. We have provided donations and SHI Group
employees are also participating in the reforestation activities.

In the aim of realizing a sustainable society, the SHI Groupendorsed the Keidanren Initiative for Biodiversity Conservation, whichindicates the intent and action guidelines from the standpoint ofcompanies to address the issue of biodiversity conservation.
Our main activities have been to reduce wood in packaging,address the issue of marine plastics, and promote green spaces andtree planting around production plants.

Endorsement of Japan Climate Initiative
SHI Group has endorsed the message of the Japan Climate
Initiative: “Now is the time to accelerate renewable energy
deployment: Calling for stronger climate change action in the midstof the fossil energy crisis.” So that we may be a world leader instriving to achieve the 1.5°C target, we will accelerate our own
activities to increase energy efficiency and renewable energy use
as well as strengthen collaboration with non-state actors
domestically and internationally as part of our efforts to bolster
initiatives that contribute to achieving net zero CO2 emissions by
2050.

All devices containing high concentrations of PCBs wereregistered early on with the waste-disposal company the Japan
Environmental Storage & Safety Corporation. These devices havebeen systematically detoxified pursuant to the Act on Special
Measures Concerning Promotion of Proper Treatment of PCB
Wastes. Transformers containing PCBs and stabilizers for lighting
equipment containing PCB have been replaced or updated
sequentially. Some Works and affiliated companies havecompleted all such disposal. Additionally, we have completed oursurvey to identify equipment containing low concentrations of
PCBs, and have been working to detoxify such equipment insequence by the deadline.
