NASTT's Carbon Calculator

In order to promote trenchless technology as a "green" alternative, NASTT collaborated with a consortium of North American gas and electric utilities to develop a calibrated comparison tool between traditional open cut construction and trenchless applications.

NASTT’s Carbon Calculator is an ever evolving tool for trenchless professionals. We will work to continually improve this comprehensive suite of information and refine its capabilities. NASTT’s Carbon Calculator was built by and for our membership, and we welcome your feedback. If you have any questions, comments or suggestions, please contact us.

The Carbon Calculator is a complimentary benefit of NASTT membership. Not a member? Join NASTT Today!
