Green Practices
Five working pillars.
Air, water, energy, design, and innovation. Each pillar collects the technologies and operating decisions that shape a terminal’s environmental footprint, written for the people who have to build and run the place.
Practice Areas
Pick a pillar. Get the specifics.
Every practice page follows the same rule: name the technology, show the numbers, state the tradeoffs. These are approaches TDG has built, priced, or tracked closely enough to report on honestly.
Practice 01 / 05
Air Quality
Marine hoteling emissions, GenSet switching locomotives, AMECS and ALECS treatment, and Clean Air Action Plans.
Practice 02 / 05
Water Systems
Bioswales, retention systems, porous pavement, and floating berths for shallow-water habitat preservation.
Practice 03 / 05
Energy Efficiency
Solar PPAs and leases, SRECs, RECs, FITs, and the financing that makes on-site generation pencil out.
Practice 04 / 05
Terminal Design
Zoned pavement sections, high SRI surfaces, rainwater capture, and open-grid paving at terminal scale.
Practice 05 / 05
Innovation & Resilience
Emerging technologies and case-led learnings from peer ports. Updated as field data comes in.
Proven In The Field
Where these practices have shipped.
Five facilities where an approach was implemented, measured, and either kept or revised. Client names and numbers included.
Water Systems
T6 Porous Pavement
Port of Portland. Multi-decade porous-asphalt installation with the spec, maintenance program, and cold-weather record.
