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 aims to provide fleets and governments with comprehensive information 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. OEMs and others are invited to complete this form to update current listings or add new vehicles. For more information or feedback, email us at info@globaldrivetozero.org.

The ZETI Tool interface was updated recently to include the ability to filter between battery-electric and hydrogen fuel cell vehicles, a feature allowing the comparison of up to three vehicles within a region, and a “badge” icon indicating vehicles for which incentive funding is available for in the U.S.
