In order to realize a decarbonized society, the Tokyo Metropolitan Government has started an initiative to use "biofuel" made from euglena, a kind of algae, which is said to have a low environmental impact, as fuel for metropolitan buses.

From the 25th, the Tokyo metropolitan government started efforts to use "biofuel" as fuel for seven metropolitan buses running in the city center, such as Shinjuku and Ikebukuro, and a departure ceremony was held at the Tokyo Metropolitan Government Office, attended by Governor Koike and others. .

This "biofuel" is made from a type of algae, Euglena, and used vegetable oil, and when burned, carbon dioxide is generated, but Euglena and plants absorb carbon dioxide in the process of growth. This means that emissions can be considered zero.

80% of the fuel is light oil and 20% is "biofuel", and it will be operated for about a month from the 25th.

After the ceremony, Governor Koike said, "There is no time to wait for climate change measures. I think that people are experiencing the energy crisis through things such as rising electricity bills. Such a crisis is also an opportunity to tackle new things. I want to do it," he said.
