Use of the Logo


A technology verified under the ETV Program is issued with the ETV logo. There are two types of ETV logo: common logo representing information common to all technology fields and field-specific logo featuring a specific field.

Common Logo Field-Specific Logo
ETV in the common logo stands
for Environmental Technology Verification.
A field-specific logo carries specific information
on the relevant technology field.
