Initiatives for Environment
Environmental Targets
CIM has formulated the "Energy Conservation Policy", the "Greenhouse Gas Emissions Reduction Policy", the "Water Saving Policy", the "Waste Management Policy" and the "Policy for Climate Change Related Issues" which stipulate efforts to reduce environmental impact in real estate investment management operations. Through the cycle of planning, implementation, performance management, and improvement set forth in the "Environmental Management System (EMS) Operation Manual" that stipulates the details for operating these policies, CIM will strive to continuously reduce the environmental impact.
In accordance with the Act on the Rationalization etc. of Energy Use (Energy Conservation Act), CIM sets the following quantitative targets for the continuous reduction of energy consumption throughout the portfolio.
- Long-term target 1: Reduce annual (Note 1) energy consumption intensity within the owner management scope (Note 2) by 5% in 2029 from 2024 levels
- Long-term target 2: Reduce the annual energy consumption intensity within the tenant management scope (Note 3) by 1% in 2029 from 2024 levels
Regarding greenhouse gas emissions, in accordance with the reduction target for energy consumption, the basic target for the adjusted scope 1+ scope 2 (Note 4) is to reduce the emission intensity by 5% in 2029 from 2024 levels. The basic target for the adjusted scope 3 (Note 5) and the adjusted scope 1+ scope 2+ scope 3 is to reduce the emission intensity by 1% in 2029 from 2024 levels.
Regarding water usage and waste volume, our target is not to increase each intensity level in the five years from 2025 to 2029 compared to 2024 levels.
The Sustainability Committee compares target and actual values and appropriately considers measures to achieve each environmental target. The scope of the initiatives for reducing energy consumption and greenhouse gas emissions is the energy consumption through the use of lighting, air conditioning, and various facilities in INV's portfolio, specifically refers to 1) purchased electricity, 2) city gas/LP gas, etc., 3) heavy oil/kerosene/gasoline, etc., and 4) purchased steam, hot and cold water, and district heating and cooling etc. consumed on-site.

Environmental Management System (EMS)
EMS Policy
CIM recognizes energy conservation and reduction of GHG emission and others as important environmental issues for our real estate portfolio and is committed to addressing these issues in our sustainability policy. CIM has developed the "energy conservation policy", "GHG emission reduction policy", "water-saving policy" and "waste management policy" which define initiatives toward the reduction of environmental impact in the real estate investment management business. Furthermore, CIM has been working to reduce our environmental impact through PDCA (Plan/Do/Check/Act) cycle based on our EMS policy which specifies the details for managing these policies.

Initiatives by Hotel Operator
INV and ICN, the main operator of hotels owned by INV have been implementing various initiatives to promote energy savings and CO2 reduction related to hotel operations and to preserve biodiversity in the surrounding areas.
Various Initiatives for Energy Conservation and CO2 Reduction
- Eco-friendly plan at hotel "ECO-Plan"
Encouraging guests to use eco-friendly plans by lowering the price of plans that do not require linen exchange when guests stay 7 consecutive nights
- Conducted energy-saving checks
- Reducing greenhouse gas emissions from Food Transportation at Hotels (Hotel Epinard Nasu)
Contributing to CO2 reductions by cooperating with farmers and dairy farmers in Tochigi Prefecture to reduce the procurement from prefectures other than Tochigi
Introduction of EV infrastructure "Terra Charge"
Decided to introduce EV charging infrastructure "Terra Charge" provided by Terra Motors Corporation in most of hotels operated by ICN as one of the measures to achieve a decarbonized society. 157 units have been installed at 91 hotels as of the end of April 2026, and further 16 hotels plan to install units in 2026 to protect the environment and improve convenience of hotel guests.

Biodiversity Initiative
Hotel Epinard Nasu
In order to reduce the impact of deforestation on the ecosystem, tree felling was minimized during hotel development. In the blueberry farm area, we are working to conserve the forest by planting more blueberries than were cut down. Furthermore, hotel provides the activities and nature tours that guests can enjoy in the rich natural forest which is home to insects and small animals.
Art Hotel Ishigakijima
Participated in forestation activities of mangroves organized by Lions Club of local area. It is said that mangrove helps to reduce effect of global warming by absorbing CO2 and store carbon which are main factor of global warming. Furthermore, it also serves as a "green breakwater" that protects people's lives and ecosystems from natural disasters such as tidal waves and tsunamis.
Fusaki Beach Resort Hotel & Villas
With the aim of preserving the rich nature of Ishigaki Island, from June 13, 2022, we are replacing toothbrushes and hairbrushes made with 100% plant derived materials that biodegrade in seawater. In addition, the razors provided to guests have been replaced by the ones containing renewable biological resources consisting of waste parts of wheatgrass. Furthermore, plastic packaging was changed to paper packaging in the aim of reducing the amount of plastic waste.
Phoenix Seagaia Resort (Note 1)
Under its sustainability vision, "A resort that revitalizes both people and the planet," the resort conducts annual beach clean-up activities, "Seagaia Beach Clean in Hitotsuba," along the Hitotsuba Coast. These activities are carried out prior to the nesting season of loggerhead sea turtles--designated as a natural monument (protected species) by Miyazaki Prefecture--to help protect their nesting grounds.
The resort also participates in a project aimed at restoring areas in the Hitotsuba area affected by pine wilt disease, and engages in initiatives such as donating used linens from hotel guestrooms to the nearby Miyazaki City Phoenix Zoo.

Initiatives by Other Hotel Operators
Sheraton Grande Tokyo Bay Hotel ("SGTB")
SGTB offers a program for guests to experience "plogging," an activity that combines fitness and environmental conservation which originated in Sweden. The term "plogging" is a combination of the Swedish phrase plocka upp ("to pick up") and "jogging," and refers to a global movement that merges exercise with environmental protection.
This simple yet meaningful activity involves picking up litter while running and has gained popularity worldwide for more than a decade as a new form of sport addressing environmental issues. Guests can participate casually through complimentary rental of plogging kits--including gloves, garbage bags, and guidebooks on the local ecosystem--as well as high-performance running shoes. This experience encourages collaboration between guests and local residents toward shared environmental goals and fosters a sense of collective responsibility to nurture and protect the natural environment. It also provides an opportunity for guests to build deeper connections with the local community while making a positive impact on the surrounding ecosystem during their stay.
The Westin Grand Cayman Seven Mile Beach Resort & Spa
Collaborates with "Beneath the Waves Foundation" who are working with the Cayman Islands Department of Environment to establish a deep-sea marine protected area in The Cayman Trench, the deepest point of the Caribbean Sea, and contributes to ocean conservation through nature-based solutions to climate change. Furthermore, the hotel provides groups and leisure guests an opportunity for turtle releases with "The Cayman Islands Turtle Centre". Sea turtles have a positive impact on the marine ecosystem as well as the beach and dune ecosystems. Turtle releases ensure that the turtle is older when it reaches the water, increasing their survival rate, and contributing to a healthy marine environment.
INV has been implementing various initiatives to promote energy savings and CO2 reduction related to hotel operations in the surrounding areas.

Biodiversity Initiative
Hotel Epinard Nasu
In order to reduce the impact of deforestation on the ecosystem, tree felling was minimized during hotel development. In the blueberry farm area, we are working to conserve the forest by planting more blueberries than were cut down. Furthermore, hotel provides the activities and nature tours that guests can enjoy in the rich natural forest which is home to insects and small animals.
Art Hotel Ishigakijima
Participated in forestation activities of mangroves organized by Lions Club of local area. It is said that mangrove helps to reduce effect of global warming by absorbing CO2 and store carbon which are main factor of global warming. Furthermore, it also serves as a "green breakwater" that protects people's lives and ecosystems from natural disasters such as tidal waves and tsunamis.
Fusaki Beach Resort Hotel & Villas
With the aim of preserving the rich nature of Ishigaki Island, from June 13, 2022, we are replacing toothbrushes and hairbrushes made with 100% plant derived materials that biodegrade in seawater. In addition, the razors provided to guests have been replaced by the ones containing renewable biological resources consisting of waste parts of wheatgrass. Furthermore, plastic packaging was changed to paper packaging in the aim of reducing the amount of plastic waste.
Phoenix Seagaia Resort (Note 1)
Under its sustainability vision, "A resort that revitalizes both people and the planet," the resort conducts annual beach clean-up activities, "Seagaia Beach Clean in Hitotsuba," along the Hitotsuba Coast. These activities are carried out prior to the nesting season of loggerhead sea turtles--designated as a natural monument (protected species) by Miyazaki Prefecture--to help protect their nesting grounds.
The resort also participates in a project aimed at restoring areas in the Hitotsuba area affected by pine wilt disease, and engages in initiatives such as donating used linens from hotel guestrooms to the nearby Miyazaki City Phoenix Zoo.

Initiatives by Other Hotel Operators
Sheraton Grande Tokyo Bay Hotel ("SGTB")
SGTB offers a program for guests to experience "plogging," an activity that combines fitness and environmental conservation which originated in Sweden. The term "plogging" is a combination of the Swedish phrase plocka upp ("to pick up") and "jogging," and refers to a global movement that merges exercise with environmental protection.
This simple yet meaningful activity involves picking up litter while running and has gained popularity worldwide for more than a decade as a new form of sport addressing environmental issues. Guests can participate casually through complimentary rental of plogging kits--including gloves, garbage bags, and guidebooks on the local ecosystem--as well as high-performance running shoes. This experience encourages collaboration between guests and local residents toward shared environmental goals and fosters a sense of collective responsibility to nurture and protect the natural environment. It also provides an opportunity for guests to build deeper connections with the local community while making a positive impact on the surrounding ecosystem during their stay.
The Westin Grand Cayman Seven Mile Beach Resort & Spa
Collaborates with "Beneath the Waves Foundation" who are working with the Cayman Islands Department of Environment to establish a deep-sea marine protected area in The Cayman Trench, the deepest point of the Caribbean Sea, and contributes to ocean conservation through nature-based solutions to climate change. Furthermore, the hotel provides groups and leisure guests an opportunity for turtle releases with "The Cayman Islands Turtle Centre". Sea turtles have a positive impact on the marine ecosystem as well as the beach and dune ecosystems. Turtle releases ensure that the turtle is older when it reaches the water, increasing their survival rate, and contributing to a healthy marine environment.
