The EU commission has announced amendments to ecodesign from Directives to Regulations. This ecodesign regulation includes expanding the scope of targets from existing ErP (Energy-related Products) to physical products placed on the market, which adds requirements for product performance and information. In particular, among these requirements, information on environmental impacts is also required, and the LCA methodology is used to derive such environmental impact information, and EPD is a representative certification system. EPD is a global standard, an environmental label for Type III (ISO 14025), which can evaluate environmental performance across products based on LCA. These environmental labels are an effective way for corporations to provide clear and reliable information to consumers, and corporations need to establish various business systems and processes to respond quickly to international change. To this end, EPD-Norge and IGSC developed an EPD certified auditor program curriculum to train manpower, and established an “Internal Audit Process” through such trained internal auditing experts. Through the established “Internal Audit Process,” the environmental performance of a corporation’s products can be directly calculated, and its own internal auditing can also be participated before the certification auditing. Through this process, the product’s EPD certification acquisition period can be shortened by 1 month, and EPD information that can be used internationally can be calculated and disclosed through internal calculations.
