Ensuring the Reliability of Petroleum Products
Based on the Cosmo Energy Group’s Quality Policy, the Sustainability Strategy Committee at Cosmo Energy Holdings sets quality targets for the entire Group, determines quality assurance policies and promotes activities in line with Group quality targets.
In fiscal 2023, we made zero of serious product (quality) accidents a KPI and stepped up our quality control activities. Our refineries and plants continued to maintain a record of zero serious quality-related issues and shipments of non-conforming products.
Cosmo Oil and Cosmo Oil Marketing have established committees related to quality assurance to decide on quality assurance policy and promote activities in order to provide safe products that meet the quality requirements of customers in an economical, stable manner. The committees of the two companies work with the Sustainability Strategy Committee at Cosmo Energy Holdings, forming the Group quality assurance structure.
