GHG Engineering LLC began operations in 2014 as a transportation carbon emissions assessment and water and climate sustainability consulting firm.
GHG Engineering has worked with clients and organizations in several U.S. states and Mexico.
Our experience includes projects in the natural gas distribution, mass transit, renewable natural gas engineering, and industrial energy efficiency industries. GHG Engineering has also done pro bono work to promote sustainable transportation in Costa Rica and also participates in Maryland’s effort to prepare the state’s Proposed Greenhouse Gas Reduction Plan.
The Company believes that both private and public organizations will continue to operate in an increasingly competitive and financially constrained environment. Therefore, our focus is on delivering high value and insightful sustainable solutions and recommendations for the Client organization. We aim at assisting our Clients increase their competitive advantage. Also, as experienced implementers, we bring to our Clients a good grasp for what tends work where.
