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.

ZETI is a work in progress and will be continuously updated. Because ZETI is based on the best available data and might not accurately reflect the most recent model offerings, we would greatly appreciate your assistance in making this tool more comprehensive, accurate and robust. If you have models that are not yet in ZETI, please complete this form in order to update current listings or add new vehicles. For more information or feedback, email us at
