Initiatives to provide low-speed mobility services

This is an introduction to our Impact Assessment key initiatives.

As a last mile mobility solution,we are deploying compact low-speed electric vehicles (green slow mobility) utilizing golf car technology in various regions.　By providing mobility for elderly persons and other area residents, we are contributing to a fulfilling life for people.

Since the introduction of green slow mobility to the market in 2014, the cumulative impact has totaled 85.1 million yen. The social impact amount for the most recent year is broken down as follows.

Impact Field	Impact Amount(2024)
Medical field	1.1 million yen
Nursing field	33.1 million yen
Environmental field	0.2 million yen
Total	34.6 million yen

Based on the method of impact weighted accounting (IWA) proposed by Harvard Business School in the United States, we developed the above calculation formula and converted social impact into monetary value.

*　The above operation areas are areas used for daily life purposes where service was in operation for more than two months
* The estimated number of users (not the total number of people) is 3,156 people in total. By major area: Osaka Prefecture:799, Chiba Prefecture:764, Shimane Prefecture:389, Aichi Prefecture:285, Nara Prefecture:255.

Methodology for Calculating Impact Amount

(Medical field) Medical cost reduction:
Estimated number of users^*1 × Average number of days when riding × Average increase in number of steps when riding × Medical cost reduction effect per step^*2

*1 Calculated by considering fluctuations based on empirical data and interviews with drivers, etc.
*2 Use of the Ministry of Land, Infrastructure, Transport and Tourism's “Guidelines for Walking Volume (Step Count) Survey to Ascertain Health Promotion Effect in Urban Development”

(Nursing care field) Nursing care cost reduction:
Estimated number of users at least once a month^*1 × Amount of nursing care cost reduction effect^*2

*1 Calculated by considering fluctuations based on empirical data and interviews with municipalities, etc.
*2 Created by Yamaha Motor citing the results of a joint study with Chiba University

(Environment field) Amount of CO₂ reduction:
Number of vehicles in operation × Average number of passengers during driving × Total distance traveled × (Gasoline vehicle emissions intensity − Low-speed mobility emissions intensity) × Conversion rate from owner-driven cars × Internal carbon pricing of Yamaha Motor
