Sustainability for Port Directors

The Port Director's Sustainability Challenge

Ports sit at the nexus of global trade and local environmental impact. The International Maritime Organization (IMO) has committed to net-zero GHG emissions from international shipping by around 2050, with a reduction of at least 20%, striving for 30%, by 2030 compared to 2008 levels. For Port Directors, this isn't an abstract target—it translates into immediate operational decisions about shore power infrastructure, equipment electrification, fuel bunkering capabilities, and land-use planning for clean energy generation. The ports that invest now will attract the next generation of vessel traffic. Those that don't will watch cargo shift to competitors.

Simultaneously, ports face intense scrutiny from adjacent communities. The American Lung Association's State of the Air 2026 report once again ranked Los Angeles-Long Beach, home to the nation's largest port complex, as the most ozone-polluted metro area in the country. Diesel particulate matter from drayage trucks, cargo handling equipment, and ocean-going vessels contributes to elevated rates of asthma, cardiovascular disease, and premature death. Community advocacy organizations have become sophisticated in their use of air quality monitoring data and regulatory engagement. The South Coast Air Quality Management District and similar bodies nationwide are demanding measurable improvements—not just pledges.

The financial dimension is equally important. EPA's Clean Ports Program, funded through the IRA, selected nearly $3 billion in grants in 2024, and ports are now implementing 51 projects with that money; no new funding round has been announced. State programs, such as California's CORE vouchers for zero-emission off-road equipment, remain a source of capital for zero-emission equipment, charging infrastructure, and renewable energy installations. But competition for these funds is fierce, and applications require detailed emissions inventories, environmental justice analyses, and implementation timelines that many port authorities lack the internal capacity to produce.

Key Responsibilities

Emissions Inventory & Reduction Planning. Maintain a comprehensive port-wide emissions inventory covering ocean-going vessels (at berth and in transit), harbor craft, cargo handling equipment, drayage trucks, rail operations, and administrative facilities. Develop reduction pathways aligned with IMO 2030 and 2050 targets.

Shore Power & Electrification. Plan and deploy cold ironing (shore power) infrastructure for container, cruise, and tanker berths. Develop charging networks for battery-electric cargo handling equipment, drayage trucks, and yard tractors.

Alternative Fuel Strategy. Evaluate and invest in bunkering infrastructure for alternative maritime fuels—LNG as a transitional fuel, green methanol, green ammonia, and green hydrogen. Partner with fuel suppliers and shipping lines to ensure demand-supply alignment.

Community Health & Environmental Justice. Engage with port-adjacent communities on air quality monitoring, health impact mitigation, and equitable distribution of clean energy benefits. Design programs that direct measurable benefits to the neighborhoods most exposed to port pollution. The federal Justice40 initiative was rescinded in January 2025, but state programs such as California's still give priority to disadvantaged communities.

Federal & State Grant Capture. Lead applications for state incentive programs and any new federal funding opportunities. Manage grant compliance, reporting, and performance metrics post-award, including on Clean Ports grants now being implemented.

Climate Adaptation & Resilience. Assess port infrastructure vulnerability to sea level rise, storm surge, extreme heat, and changing precipitation patterns. Develop adaptation plans for critical assets including berths, terminals, rail connections, and road access.

Regulatory Pressure Points

IMO GHG Strategy (2023 Revision). Targets net-zero GHG emissions from international shipping by around 2050, with checkpoints of at least 20% reduction (striving for 30%) by 2030 and at least 70% (striving for 80%) by 2040, compared to 2008. The IMO approved a draft Net-Zero Framework, combining a global fuel standard with greenhouse gas pricing, in April 2025, but it has not been adopted: in October 2025 member states voted to adjourn the adoption session for a year, and the committee's April 2026 meeting set no timeline for approving a revised framework.

EPA Clean Ports Program. The IRA provided $3 billion for competitive grants for zero-emission port equipment, infrastructure, and climate and air quality planning. EPA selected recipients in 2024, and ports are now implementing 51 projects worth nearly $3 billion over three to four years; no new funding round has been announced.

CARB At-Berth Regulation (California). Requires ocean-going vessels to reduce at-berth auxiliary engine emissions by using shore power, capture-and-control systems, or equivalent technologies. Applies to container, reefer, cruise, roll-on/roll-off, and tanker vessels at California ports, with tanker requirements at all regulated terminals from January 1, 2027.

CARB Advanced Clean Fleets Rule. The rule originally required a transition to zero-emission drayage trucks at California ports beginning in 2024, with full transition by 2035. In September 2025 CARB repealed the drayage requirements, along with the rule's other requirements for private and federal fleets; it now applies only to state and local government fleets.

EU Emissions Trading System (ETS) for Maritime. As of 2024, maritime transport is included in the EU ETS. Shipping companies must purchase emissions allowances for voyages to, from, and within the EU. Ports that can offer low-carbon bunkering and shore power become more attractive to carriers seeking to minimize their ETS exposure.

EPA National Ambient Air Quality Standards (NAAQS). Port operations contribute to regional attainment status for PM2.5, NOx, and ozone. Non-attainment designations can trigger permitting restrictions and offset requirements that directly affect port expansion plans.

Quick Wins

1. Complete a Scope 1-3 emissions inventory. Use EPA's Port Emissions Inventory Guidance (April 2022) or the GHG Protocol to quantify emissions across all port operations, including tenant activities. This inventory sets the baseline for every reduction pathway and for funding applications.

2. Deploy shore power at your highest-volume berth. Start with the berth that handles the most vessel calls annually. Shore power lets vessels at that berth switch off their auxiliary diesel engines, dramatically reducing PM2.5 and NOx exposure for nearby communities. EPA's Shore Power Emissions Calculator estimates the greenhouse gas and air pollutant reductions for a given berth and regional grid mix.

3. Establish a community air quality monitoring network. Partner with local universities or community organizations to deploy PM2.5 and NO2 monitors in port-adjacent neighborhoods. Real-time, publicly accessible data builds trust and provides baseline measurements for demonstrating improvement.

4. Line up state incentives for zero-emission equipment. EPA's Clean Ports Program has committed its funds to projects already under way and has not announced a new round. In California, CORE vouchers cover zero-emission cargo handling equipment; check your state's programs for funding for cargo handling equipment, drayage truck charging infrastructure, and shore power installations. Council Fire can support application development.

5. Join the IAPH Climate and Energy Technical Committee. The International Association of Ports and Harbors (IAPH) announced in October 2024 that the World Ports Climate Action Program's working groups would move into this committee. It provides peer learning, technical resources, and credibility with international shipping lines, and connects you with ports that have already worked through the challenges you're facing.

How Council Fire Can Help

Council Fire works with port authorities to build decarbonization strategies that balance emissions reduction with operational performance and financial sustainability. We develop port-wide emissions inventories, design shore power and electrification roadmaps, and prepare competitive grant applications for the federal and state port infrastructure programs that are open at the time.

Our team understands the operational realities of port environments: berth scheduling constraints, tenant coordination challenges, grid interconnection timelines, and the capital planning cycles that determine what gets built and when. We also bring deep experience in community engagement and environmental justice program design, helping ports build genuine partnerships with adjacent neighborhoods rather than checking compliance boxes.

FAQs

How do we fund zero-emission equipment when our capital budget is already committed? Layer state incentive programs with lease financing. EPA's Clean Ports Program has already committed its nearly $3 billion to 51 projects now under way, with no new round announced, so start with state programs: California's CORE program offers vouchers for zero-emission off-road equipment, including cargo handling equipment. Council Fire helps ports develop blended funding strategies that minimize out-of-pocket capital expenditure.

What alternative fuel should we invest in for maritime bunkering? It depends on your vessel traffic profile. Green methanol is gaining traction for container shipping (Maersk has ordered 25 methanol-capable vessels). LNG serves as a transitional fuel for cruise lines. Green ammonia is the leading candidate for long-haul bulk and tanker routes. Avoid locking into a single fuel—design flexible bunkering infrastructure that can accommodate multiple fuel types as the market matures.

How do we manage community opposition to port operations? Start with transparency. Publish real-time air quality data. Invite community representatives onto advisory committees with genuine decision-making influence—not just comment periods. Fund community health studies independently. The most effective approach is demonstrating measurable air quality improvements through equipment electrification and shore power deployment, then communicating those results in accessible formats.

Are we liable for tenant emissions? Increasingly, yes—at least reputationally and in terms of regulatory compliance. While most port authorities don't directly control tenant equipment, lease agreements can include emissions reduction requirements, equipment standards, and reporting obligations. Leading ports are incorporating zero-emission equipment mandates into new and renewed terminal leases.
