Greenhouse gas emissions

Reducing our
carbon footprint

We track our greenhouse gas (GHG) footprint by closely assessing onsite activities and their environmental effects and finding opportunities to reduce emissions. Our efforts decreased direct and indirect emissions from our operations, including energy consumption at our office locations and project sites.

Sustainable mine remediation efforts at Eagle Rock Lake

Our multi-year decommissioning and remediation of a molybdenum mine led to the restoration of Eagle Rock Lake and nearby wetlands in Questa, New Mexico. Using remote monitoring and solar panels for sustainable energy, we minimized our own environmental footprint in the process.

In recognition of our efforts, ENTACT and other partners received the EPA’s Greenovations Award for their collaborative work transforming the polluted site into a thriving recreational zone.

Energy and fuel management

Exploring efficient and renewable energy sources

We implemented several measures to manage our energy and fuel consumption efficiently and reduce our carbon footprint. During the fiscal year of 2022, we reduced emissions in the following ways:



of B20 biodiesel used by heavy equipment


of purchased electricity used on project sites was renewable


of current office space upgraded to energy-efficient LED lighting

Geotechnical construction expertise fuels energy transformation project

ENTACT was pivotal in advancing clean energy infrastructure through an innovative soil stabilization project for a Liquefied Natural Gas (LNG) terminal expansion project along the Gulf Coast.

Fueled by increased domestic energy production and the need to export LNG, this transformative project harnessed our geotechnical expertise to treat over 2.3 million cubic yards of soft-dredged sediment. The project laid the foundation for the LNG terminal expansion.
