As transportation remains the largest source of U.S. greenhouse gas (GHG) emissions, accounting for roughly 28 percent of the national total, freight forwarders are under mounting pressure to decarbonize their operations and meet customer sustainability targets. Unlike the EU, the U.S. has not yet implemented a carbon price on maritime emissions, but it is deploying a suite of regulatory initiatives, grant programs, and tax incentives that will reshape ocean-leg costs, port operations, drayage fleets, and emissions reporting.

Although the U.S. has no domestic maritime emissions trading system (ETS), American forwarders importing goods into the EU will bear pass-through carbon surcharges levied by carriers on cargo bound for European ports. Carriers are currently recovering ETS costs, now averaging around €80 per tonne CO₂, via line-item surcharges that can add 5–10 percent to ocean-freight rates and influence global spot-rate benchmarks. Forwarders therefore must anticipate rate volatility tied to European carbon markets even on U.S. export cargo streams.

Domestically, the International Maritime Organization's (IMO) Carbon Intensity Indicator (CII) regulation — which rates ships’ CO₂ emissions per transport work on a scale from A (best) to E (worst), with mandatory annual improvements mandated through 2030 — will penalize high-emitting vessels with operational restrictions and potential port-state enforcement beginning in 2026. Although not a direct carbon price, the CII will drive carriers to retrofit or slow-steam vessels, which can lengthen transit times and alter sailing schedules. Forwarders should build flexible routing clauses into contracts and maintain real-time vessel performance data to adjust client expectations and optimize cost-to-carbon trade-offs.

2. Federal Incentives & Grant Programs

EPA Clean Ports Program
In late 2024, the Environmental Protection Agency (EPA) awarded 54 grants totaling nearly $3 billion to U.S. ports for zero-emission equipment, shore-power installations, and air-quality planning under its Clean Ports Program—part of the Bipartisan Infrastructure Law. Key awards include $412 million to the Port of Los Angeles for electric top-handlers and $60 million to the Port of San Diego for electrifying drayage trucks and cargo-handling equipment. These investments will dramatically cut local emissions and can be leveraged by forwarders to offer truly low-carbon drayage solutions to shippers.

Inflation Reduction Act (IRA) Tax Credits
The 2022 IRA provides tax credits and loan guarantees totaling $40 billion for clean-energy projects through 2026, with specific provisions that apply to freight infrastructure. For example:

• Section 45X Clean Fuel Production Credit incentivizes e-fuel and sustainable biofuel production that can decarbonize ocean bunkers;
• Section 48C Clean Energy Manufacturing Tax Credit (30 percent ITC) can subsidize U.S. manufacturing of electric drayage trucks, charging stations, and solar/battery systems at terminal facilities;
• Advanced Energy Project Credit supports R&D in low-carbon engine conversions and vessel retrofits.

By tapping IRA credits, medium-sized forwarders can significantly reduce the net cost of electrifying terminals, upgrading fleet vehicles, or investing in alternative fuel contracts—unlocking paybacks in 3–5 years rather than decades.

3. Emissions-Measurement Tools for the U.S. Market

Accurate, U.S.-specific Scope 3 reporting is essential to capture the impact of Clean Ports grants and IRA-enabled projects. Key platforms include:

• EcoTransIT World: Used by ports and carriers to model U.S. drayage, rail, and ocean emissions under MARPOL Annex VI rules. It is ISO 14083-validated and integrates EPA’s fuel-consumption factors for U.S. domestic voyages.
• CE-CERT’s California Freight Calculator: Incorporates CARB’s (California Air Resources Board) region-specific emissions factors and vessel speed-reduction measures being piloted on the Pacific Coast collaborative, offering precision for forwarders with intra-California or West-Coast routes.
• Pledge Freight Emissions Calculator: Delivers GLEC-aligned, API-driven data feeds into TMS/ERP systems, enriched with U.S. port call and truck movement logs to streamline real-time client dashboards.
• Chain.io Environmental SCM: Embeds CO₂e modules directly into major U.S. TMS platforms, automating compliance with forthcoming SEC climate-disclosure rules for public shippers.
• Project44 Emissions Monitoring: Provides live, GLEC-accredited emissions metrics across ocean, air, rail, and road within U.S. supply chains, enabling dynamic carrier selection and routing.

Selecting the right tool depends on your network footprint: EcoTransIT excels for ports and ocean calculations, CE-CERT for California-centric operations, and Pledge or Chain.io for seamless TMS integration and real-time reporting.

4. Collaboration Strategies for Net-Zero Freight

Partner with Carriers on Alternative-Fuel Tenders
Forwarders can aggregate client volumes to co-issue RFPs for bio-LNG, sustainable aviation fuel (SAF) for air-sea transshipment corridors, or e-fuel bunkering agreements. Although large buying alliances like ZEMBA focus on ocean e-fuels, regional forwarder consortia can foster demand for U.S.-produced renewable natural gas or green hydrogen blends, securing better pricing and preferential vessel slots.

Leverage Port Electrification
Align your drayage services with port-funded electrification projects. By contracting with carriers operating EPA-subsidized electric yard trucks and top-handlers at major hubs, Los Angeles, New York/New Jersey, Seattle, you can package “zero-emission drayage” as a premium service. This approach requires developing data-sharing agreements with port authorities to verify equipment deployment and uptime.

Engage in Public-Private Coalitions
Join initiatives like the Getting to Zero Coalition (U.S. chapter) and CARB’s Pacific Coast Collaborative to pilot cleaner-engine trials, vessel speed-reduction programs, and emission-control technology seminars. These forums provide early access to federal/state grants, insights into regulatory roadmaps, and influence over policy design, ensuring your voice shapes future incentives.

Offer Co-Branded Sustainability Reporting
Publish annual or semi-annual “Green Logistics Reports” co-authored with port and carrier partners, detailing emissions reductions achieved through Clean Ports grants and IRA-enabled upgrades. Incorporate third-party verification (e.g., from DNV or Lloyd’s Register) to validate claim integrity and support client ESG disclosures under frameworks like CDP and the forthcoming SEC climate rules.

5. Turning U.S. Decarbonization into Competitive Advantage

By proactively integrating regulatory intelligence, federal incentives, and advanced emissions-accounting tools, medium-sized forwarders can transform decarbonization from a cost center into a market differentiator. Key actions include:

1. Forecasting Indirect Carbon Costs: Model EU ETS pass-through surcharges on inbound cargo to refine long-term ocean-freight contracts and hedging strategies.
2. Maximizing IRA & EPA Grants: Develop an incentive-stacking roadmap that blends EPA Clean Ports funding with IRA tax credits to minimize capital outlays on zero-emission equipment and infrastructure.
3. Piloting Emissions-Tracking Technology: Run parallel trials of two calculators, such as EcoTransIT for ocean legs and CE-CERT for drayage, to establish consistent, audit-ready baselines.
4. Packaging Green-Freight Services: Offer tiered “standard,” “low-carbon,” and “net-zero” freight packages with transparent pricing, offset portfolios, and verifiable emissions reports.
5. Marketing Sustainability Credentials: Leverage co-branded reports and client testimonials to win RFPs from Fortune 500 shippers under pressure to decarbonize their supply chains.

As the U.S. freight ecosystem accelerates toward net zero, driven by EPA funding, IRA incentives, and IMO mandates, forwarders who lead on strategy, partnerships, and technology will claim premium market positions and deepen client loyalty. The time to plan, pilot, and scale decarbonization initiatives is now: those who hesitate risk margin erosion and reputational lag in a rapidly greening marketplace.
