The Zero-Emission Technology Inventory (ZETI) tool is an interactive online resource to establish a current and shared knowledge base for worldwide commercially available offerings of zero-emission medium- and heavy-duty vehicles (MHDVs). The tool provides fleets and governments with comprehensive information covering key vehicle specifications and insights including regions where zero-emission brands are available for purchase, and the timeline over which additional models are expected to become available. Commercial availability is defined as availability for immediate production based on placed orders.

An evaluation of model trends based on ZETI data can be found in the ZETI Data Explorer.

ZETI is a work in progress and will be continuously updated. We would greatly appreciate your assistance ensuring ZETI is comprehensive, accurate and robust.
