Since it was first built, the Tokyo waterfront has featured a district heating and cooling system. This supplies heating, cooling, and both hot and cold water generated by plants in Daiba, Aomi, and Ariake Minami via pipes in shared conduits that run through the area. The Daiba and Ariake Minami plants also use waste heat generated from waste processing plants to fight global warming by reducing CO2 emissions and using energy more efficiently. In addition to community measures, individual facilities are also implementing their own initiatives.

Tokyo Big Sight, one of Japan's leading convention facilities, is working to achieve SDGs 7, "Affordable and Clean Energy," by using LED for its exhibition hall lighting, reducing its power consumption, and reducing its CO2 emissions. A solar power system has been installed in the South Exhibition Halls, and the facility is promoting the use of renewable energy. Tokyo Big Sight also aims to reduce the amount of waste it produces to achieve SDGs 12, "Responsible Consumption and Production." It is recycling the waste that is produced by exhibitions, promoting the reuse of resources such as turning organic waste from restaurants in the site into animal feed and preventing illegal waste dumping by appropriately supervising waste disposal and processing.

Long ago, the Shinagawa/Takanawa area was said to have had posthouses for horses and is now home to Shinagawa station, which is close to Haneda Airport. More recently, the Takanawa Gateway Station also opened in 2020 and continues to develop as the gateway to Tokyo. The Shinagawa area has many cultural assets such as temples and facilities with beautiful ancient Japanese gardens. The DMO is promoting SDG initiatives that utilize Shinagawa’s practices of passing on traditional cultures and taking good care of the environment.

In addition to reducing food loss, businesses in the area are engaged in numerous initiatives, including interregional cooperation to effectively utilize unused agricultural products (such as fruits that are considered substandard) from other prefectures, and preserving traditional cultures through classes at local elementary schools.

For example, the Prince Hotel contributes to sustainable business events by contributing to renewable energy, choosing menus with sustainable ingredients, setting up reusable exhibits, and using recycled tablecloths as part of the “Prince Hotel Sustainable Business Events” program. In addition, they are also working to help local government environmental efforts by donating savings made when customers do not utilize hotel amenities or laundry services.

The Takanawa Gateway Convention Center, which will open in 2025, plans to recycle food waste from its catering services using the East Japan area's first built-in biogas facility, located within the Takanawa Gateway City complex. The Convention Center building, THE LINKPILLAR 1, has also received preliminary V4 of the LEED BD+C (building design and construction) certification at the Gold level under the globally recognized LEED (Leadership in Energy and Environmental Design).

DMO GATEWAY Takanawa/Shinagawa will continue promoting sustainable business events by leveraging the strengths of each business in the area as well as strengthening initiatives with residents and other communities.

The Tachikawa area has a new type of activity, the Tama River Cleaning Activity, in which participants raft down the Tama River in the beautiful nature of Okutama and pick up trash from the river and its shores. The event is easy to participate in as all participants need to bring is a change of clothes. The event is a lighthearted competition between teams of rafters to see who can collect the most trash. The Tama River Cleaning Activity also allows participants to reflect on the natural environment and their own lifestyles. Before boarding the raft, a former second-place title holder of the World Rafting Championships gives the rafters a speech. This event can be enjoyed by everyone, even those who have never been rafting and those who cannot swim. After the river cleaning, there is a presentation regarding the forests in Okutama at the head of the river, which supplies the city of Tokyo, and about the area's environmental protection efforts. The program reaffirms the importance of keeping the Tama River clean and the tremendous contributions the cleaning activities make to the global environment.

DMO SHIBA, Tokyo Bay covers the Hamamatsucho, Takeshiba, and Shibaura areas, a diverse environment that includes sea transport and tidelands. Many of DMO SHIBA, Tokyo Bay members have a strong interest in the environment and conduct sustainability initiatives.

At Tokyo Portcity Takeshiba, the Takeshiba Shin Hakkei building seeks to conserve biodiversity through eight landscapes: Sky, Bee, Rice Field, Garden, Aroma, Water, Island, and Rain. In the Rice Field and Garden areas, visitors can try their hands at planting and harvesting rice, vegetables, and herbs and attend workshops regarding environmental conservation. They can experience the harmony between biodiversity and Japanese culture. Port Hall/Port Studio are also taking part in the CO2 Zero MICE. This service package, offered by JTB Communication Design, offsets the power used at MICE sites with renewable energy, resulting in events with net zero effective CO2 emissions. The initiative has drawn a great deal of attention from MICE operators.

Takeshiba Tidal Flat, part of WATERS takeshiba, is a conserved tideland area. It was created to protect and restore the Tokyo Bay environment, which once teemed with shellfish and other ocean life. Visitors to the tideland can observe the natural ecosystem or try their hands at fishing. Together with the ship transport that can be experienced to and from Takeshiba, the area provides MICE content that traces the history of the area, which developed in step with the waterside environment.
