Yokogawa actively develops environmentally friendly products through the implementation of its own strict standards of design and assessment for long-term usability, energy-saving performance and other aspects. New products are evaluated for energy consumption as well as the emission of carbon dioxide (CO2), nitrogen oxide (NOx) and sulfur oxide (SOx) based on our "Lifecycle Assessment (LCA) standards."
We have established assessment standards in eight areas: ease of recycling and treatment, resource conservation, energy conservation, long-term usability, ease of collection and transport, safety and environmental protectiveness, information disclosure, and packaging. These standards are used in conducting assessments during each inspection (initial design, intermediate design, and final design).
The LCA standards are used for preliminary assessments of energy use, CO2 emissions, NOx emissions, SOx emissions, and the like throughout the lifecycle of a product. These standards are used in conducting assessments during each inspection (initial design, intermediary design, and final design).
These guidelines state for long-life design, energy-saving design, resource-saving design, recycling-disposal design and processing as well as the design considered processing and assembly and the guideline for selecting materials and parts.
The following criteria are provided to ensure that environmentally friendly parts and materials are selected during the design phase. Controlled substances are classified into five different levels:
|Banned Substance 1:||Any substance that is banned from inclusion in a product|
|Banned Substance 2:||Any RoHS command regulated substance|
|Controlled Substance 1:||Any SVHC (substance of very high concern) under the REACH regulation|
|Controlled Substance 2:||Any substance that is banned at certain concentrations, bound by the limited purposes of use or restricted in any way|
|Controlled Substance 3:||Any substance for which the amount contained in a product must be identified|
These standards encourage the three Rs: the reduction of waste and the reuse and recycling of used products.
These guidelines state that the matters to be ensured energy-saving design in product use and manufacturing processes.
Various laws and regulations have been put in place, such as the Home Appliance Recycling Law and Law for Promotion of Effective Utilization of Resources in Japan, as well as the Waste Electrical and Electronic Equipment (WEEE) and Restriction of Hazardous Substances in EEE (RoHS) Directives outside Japan. With this background, Yokogawa aims at building a sustainable society in various areas of its business activities.
Based on the principle "Resource procurement with less environmental load = Offering environmentally friendly products," Yokogawa proactively promotes green procurement activities that are environmentally friendly.
Under the philosophy to contribute to building a sustainable society in various areas of business activities, Yokogawa has created the "Green Procurement Guidelines" to promote green procurement activities.
