Transition to a Decarbonized Economy and Promotion of Innovation

• Yokohama’s economy is largely supported by industries

such as oil refining, thermal power generation, and gas.✓ The oil refining industry accounts for about 10% of Yokohama’s entire product

and about 40% of its income acquired in other areas.

• Challenge of transition to a decarbonized economy,

toward the goal of “Zero Carbon Yokohama.”

• Yokohama SDGs Design Center for collaboration among

multi-stakeholders

→ Promotion of decarbonized innovation with

the 4th Industrial Revolution

→ Support for transition to local companies

• Foundation for the further growth of Yokohama’s

economy.
