About Yokowo

Promotion of CSR


The Yokowo Group recognizes that conducting business activities in harmony with the global environment is an essential responsibility for a corporation. The Yokowo Group continues to implement a range of Group-wide environmental preservation activities based upon defined environmental policies in order that we can pass on our irreplaceable global environment to future generations.

Considering that the Yokowo Group cannot gain social and stakeholder confidence unless it develops and strongly implements more concrete climate change measures, the Group revised its Environmental Policy and Action Guidelines on October 15, 2021. The Group will strengthen the CSR Promotion Department and adopt specific measures, including a reduction in greenhouse gas (scope 1 and scope 2) emissions. The Group will disclose these measures and progress in their implementation in the CDP (Carbon Disclosure Project) framework. The Group will also put more effort into reducing scope 3 greenhouse gas emissions.

Environmental Policy

Today, when Japan and the rest of the world are starting to make a serious effort to realize carbon neutrality by 2050, Yokowo is living up to the needs that our stakeholders and society as a whole have in us by formulating more concrete measures in response to climate change, and working actively to implement them. From this point of view, we support the recommendations of the FSB Task Force on Climate-related Financial Disclosures (TCFD), and we implement specific initiatives to achieve the target of reducing greenhouse gas emissions from our plants (Scope 1 & 2) by 35% by FY2030, compared to FY2014 and promote specific climate-related information disclosure.

Yokowo is also committed to helping to create a rich natural environment. We seek to do this through our environmental management system and through activities designed to achieve continuous improvements in environmental performance. As part of our commitment, we take into consideration the environmental impact of our business activities and comply with all relevant environmental laws, regulations, and guidelines, as well as with each customer's specific guidelines.
