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 area is said to have contained staging posts, where travelers could replace their exhausted horses with fresh animals. Now, it is home to Shinagawa Station, the closest hub station to Haneda Airport. Takanawa Gateway Station was opened in 2020, and development work on the station continues to be carried out. The Shinagawa area has long flourished as a gateway to the city, a place that brings people together. It also has many cultural assets, such as temples and facilities with beautiful and historical Japanese gardens. DMO is promoting SDGs efforts against the area's backdrop of dedication to passing on traditional culture to future generations and taking good care of the environment.

Companies in the area are pioneering efforts such as introducing digital transformation (DX) in MICE events and conducting "green slow mobility" demonstration testing. They are also working to reduce food loss and coordinating with other companies in the region to effectively utilize unused farm products from other prefectures (such as fruits that haven't been sold due to failing to meet specification standards), passing on traditional culture through classes in local elementary schools, and carrying out a variety of other initiatives.

In addition to enterprise-specific initiatives, in 2021, a new program was launched: companies, schools, and residents in the Takanawa Gateway Station area began growing hops, one of the ingredients used in brewing beer. Through this hops-growing community activity, participants hope to foster greater collaboration and communication.

DMO Gateway Shin-Shinagawa is highlighting the distinctive qualities of each of the enterprises in the area and enhancing its collaborative efforts with local residents and other communities to promote the attraction of sustainable MICE events.

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.
