Our ZETI tools equip users, industry stakeholders, and policy makers with up-to-date knowledge of the commercially available offerings within the global zero-emission vehicle and equipment markets. The Zero-Emission Technology Inventory (ZETI), which tracks on-road zero-emission truck and bus offerings, is presented in English, Spanish, and Dutch. Zero-Emission Technology Inventory (ZETI) Data Explorer enables users to analyze and compare the data gathered in ZETI from different angles. The Off-Road Zero-Emission Technology Inventory (ZETI) acts as a resource for finding commercially available zero-emission off-road and non-road vehicles and equipment across global markets.
