Green eco-project

The Tokyo Trucking Association has launched the "Green Eco Project," which includes its own measures to reduce CO2 emissions, in an effort to address global warming prevention measures. Our company supports this project and has established a database based on fuel consumption collected from each vehicle to promote continuous eco-driving activities, reduce CO2 emissions, minimize costs associated with higher fuel consumption, and prevent accidents.

Green purchasing

Our company carefully consider the necessity of purchases, and ensure that goods are purchased not only on the basis of quality and price, but also with environmental considerations in mind. When making purchases, we select green products that comply with the "Green Purchasing Law," "Eco Mark," and work to increase the purchase rate of green products.

CO2 reduction by solar power generation.

Fossil fuels (petroleum, coal, etc.), which are currently Japan's main energy sources, are depletable resources with limited availability, and they emit CO2 that causes global warming when used, creating an environmental burden that is becoming an issue.
Therefore, as a countermeasure against global warming, there is an urgent need to drastically reduce greenhouse gas emissions throughout the world, and increasing the ratio of renewable energy is considered a necessary initiative to maintain and develop society.
Among these, solar power generation is one of the renewable energy sources expected to become an important low-carbon domestic energy source. "Renewable energy" produced by solar power generation is a clean energy source that emits less greenhouse gases during power generation compared to fossil fuels.

As part of our efforts to reduce greenhouse gas emissions, we began a solar power generation project on the roof of our office in September 2015.
By utilizing renewable energy from sunlight, we will contribute to CO2 reduction and climate change countermeasures.
