CFC CEO Mr. Takeshi Nakanishi
Our targets is to reducec Scope 1 and Scope 2 emissions by 42% by 2030 comparing to 2020 as the base year. We view reducing environmental impact as a corporate responsibility and are working toward realizing a sustainable society.
In March 2009, we began planting trees in the “Global Forest” located in Inner Mongolia, China. This CSR activity is based on the concept of “carbon offsetting,” where tree planting is conducted in proportion to the amount of waste delivered by emitting companies. We will continue carbon offsetting to sustain our tree planting activities and contribute to preventing global warming.
