Fields / Categories

In 2019, designations of technology fields were revised, and now comprise 6 technology fields.
Expanding the scope of technology fields has made it possible to verify environmental technologies that were not verifiable under existing designations.

What are “fields”? The Ministry of the Environment determines technology fields subject to verification (6 fields at present) based on technological trends, market demands, social needs, etc., considering the advanced environmental technologies that are already in use but are not yet widely used due to the lack of objective evaluations regarding their effects on environmental conservation, etc.

What are “categories”? The Ministry of the Environment determines the technology areas to be verified based on technological trends, market demands, social needs, etc. (currently the above 6 areas) from the advanced environmental technologies that are already in practical use but have not become widespread due to the lack of objective evaluation of environmental conservation effects, etc.
The Ministry of the Environment classifies the candidate technologies in each field into categories for technology verification. If the candidate technology belongs to an existing category for technology verification, it is classified into that existing category for technology verification.
Technologies that do not belong to existing categories for technology verification are grouped by kind, and if the Ministry of the Environment determines that it is necessary to designate a new category for technology verification, the Ministry does so.

On Previously Designated Technology Fields

Newly designated technology fields have come into effect starting from 2019. Details related to previously designated technology fields (effective until 2018) can be looked up from the following.

• Free theme
• Renewable energy field
• Natural area human waste treatment technology field
• Organic wastewater treatment technology field
• Enclosed coastal seas water environment improvement technology field
• Lakes and reservoirs water purification technology field
• Heat island mitigation technology field (technologies for reducing air conditioning loads by using building envelope systems)
• Heat island mitigation technology field (heat pump air conditioning system using geothermal heat, sewage, etc.)

The following technology fields were subject to verification in the past, or have been suspended

• Global warming mitigation technology field (technologies to reduce energy used in lighting)
• Nonmetallic element wastewater treatment technology field (boron and other wastewater treatment technologies)
• VOC treatment technology field (VOC treatment technologies for small- and medium-sized businesses)
• Simple VOC measurement technology field
• Heat island mitigation technology field (technologies for greening IT equipment)
• Heat island mitigation technology field (technologies to suppress sensible heat generated from air conditioner outdoor units)
• Simple chemical substance monitoring technology field
