*1 Calculated based on adjusted emissions that exclude temporary factors such as fluctuations in ethylene operating rates.

*2 In Japan, calculated based on the definition of “specially controlled industrial waste” stipulated by Waste Management and Public Cleansing Act; overseas, calculated based on the definition of hazardous waste stipulated by local laws and regulations or the Basel Convention .

*3 Recycling ratio = Offsite recycling/Waste sent off-site

*4 Landfill rate for industrial waste = Landfill/Waste generated
