We're driving the global shift to low-carbon transportation — delivering end-to-end solutions that decarbonize air, rail, road and maritime systems while keeping operations resilient, connected and future ready.

Transportation is undergoing a seismic shift toward reducing carbon emissions. With our global presence, broad capabilities and focus on innovation, we are uniquely positioned to help clients navigate this transformation to zero emissions while keeping their operations running smoothly. We take a bold approach — embracing new partnerships, delivery models and ways of working to stay ahead in an ever-evolving market. 

Our integrated, end-to-end solutions help clients to transition to a decarbonized future across all transport sectors — airports, rail, roads and maritime. Using digital tools, data analytics and artificial intelligence (AI), we drive efficiency, optimize decision-making and achieve measurable results.

What we do

Our interdisciplinary, programmatic transportation decarbonization approach focuses on carbon neutrality, system resilience and designing for future demand growth.

Aviation

With aviation traffic projected to exceed airport capacity, maintaining a competitive regional and global edge requires modernized airside and landside facilities. We help clients upgrade aging infrastructure, expand capacity, improve public transport connectivity and reduce carbon emissions — all through the lens of sustainable airport development.

Ports & Maritime

Global maritime trade is projected to double in the coming decades. To stay competitive, port authorities and operators must modernize operations, expand capacity and decarbonize equipment and facilities. We provide consulting, planning and engineering services for maritime infrastructure development, supporting containerized, bulk, general cargo, energy, offshore wind and cruise/ferry industries. Our capabilities extend to port authorities, governments and some of the world’s leading naval forces.

Rail & Transit

Transitioning rail and transit systems from fossil fuels to renewable, low- or zero-carbon energy sources requires significant investment in both fleets and infrastructure. We help rail and transit owners evaluate decarbonization options using advanced analytical models to assess feasibility, compare performance, analyze end-to-end emissions and estimate costs. Our support spans every stage of the decarbonization journey — from planning and conceptual design to commissioning and maintenance —for rail fleets, yard and shop support fleets and fixed facilities.

Sustainable & Alternative Fuel Storage

Transportation accounts for about 20% of global greenhouse gas emissions. Achieving net-zero goals requires adopting hydrogen, battery-electric and e-fuel-powered vehicles. We take a holistic, systems-wide approach to designing, building and operating decarbonized transportation solutions that are effective, innovative and tailored to each client’s needs.

Electric Vehicle & Public Charging

We plan and design infrastructure to support widespread EV charging and the effective use of public space. Using data-driven insights, such as StreetLight Data, we identify optimal EV charging locations to meet the growing demand for electric vehicles.

Fleet Modernization

Fleet owners worldwide face growing pressure to transition to zero-emissions vehicles. We help public and private transportation clients develop and implement fleet modernization programs. From technology selection to engineering, procurement and program management, we ensure a smooth transition while keeping clients’ core operations at the forefront.

We apply deep environmental expertise at every stage of a project — from early advisory and permitting through design, construction and operations. Our teams work with clients to navigate complexity, manage risk and deliver responsible, resilient outcomes that strengthen communities and support long-term sustainability. 

Infrastructure has the potential to regenerate natural systems. By combining nature measurement and economics, digital insight, engineering rigor and industry collaboration, we enable clients to make informed decisions early and embed measurable outcomes into every stage of a project. The result is infrastructure that delivers lasting environmental and community benefits.  

As PFAS regulations evolve, we enable clients to stay ahead of risk. From risk assessment and site characterization to treatment design, remediation implementation and long-term management, we deliver integrated solutions that reduce liability and provide regulatory certainty. 

We combine regulatory insight, environmental expertise and economic understanding to shape practical permitting strategies. By aligning approvals, stakeholder engagement and technical evidence early, we strengthen defensibility and reduce the risk of delay. 

Strong EHS support keeps operations running smoothly. We work with clients to reduce risk, remain compliant and improve visibility across their facilities. By coordinating site support, permitting, air quality, waste and digital information systems, we make it easier to make informed decisions and maintain consistent performance across entire portfolios.  

Complex contamination demands a strategy shaped by the realities of each site. We tailor analysis remediation and risk management to local geology, contaminant profiles, regulatory context and future land use, reducing uncertainty and moving sites safely toward closure or beneficial reuse.
