The United States Marine Corps (USMC) has taken proactive measures to integrate climate and environmental considerations into its strategic framework. These efforts are part of a broader shift within the Department of Defense (DoD) to address climate change as a significant security threat. By focusing on energy efficiency, infrastructure resilience, sustainable practices, and climate-informed strategies, the USMC aims to maintain operational readiness while mitigating environmental impacts.

History and Evolution

The USMC began addressing environmental concerns in the late 20th century, driven by legislative changes such as the National Environmental Policy Act (NEPA) of 1969. Initially focused on compliance with environmental regulations, efforts expanded over time to include sustainability initiatives and climate resilience.

In 2010, the Marine Corps released its Expeditionary Energy Strategy, emphasizing the need to reduce dependency on fossil fuels in combat operations. The strategy marked a turning point, showcasing the Corps’ recognition of energy efficiency as a mission-critical factor. By the 2020s, climate change’s impacts—such as extreme weather events and rising sea levels—had become central to operational planning.

Operational Areas

1. Infrastructure Resilience

The USMC manages over 25,000 square miles of land worldwide, making infrastructure resilience a critical focus. Coastal installations, such as Marine Corps Base Camp Lejeune in North Carolina, face threats from rising sea levels and hurricanes. Recent resilience projects include:

• Hurricane Hardening: Reinforcing structures to withstand Category 5 storms.
• Flood Mitigation: Installing advanced stormwater management systems to reduce flooding risks.

For example, in 2022, the Marine Corps Air Station Beaufort implemented a $50 million project to elevate critical infrastructure above floodplains.

2. Operational Energy Efficiency

The Expeditionary Energy Office (E2O), established in 2009, leads initiatives to improve energy efficiency in field operations and reduce the logistical vulnerabilities of fuel supply lines.

Key Programs

• GREENS (Ground Renewable Expeditionary Energy Network System): A portable solar energy system providing power to remote units, reducing fuel consumption by 20-50%.

 

• Hybrid Tactical Vehicles: Development of hybrid-electric combat vehicles, such as the Joint Light Tactical Vehicle (JLTV), to enhance energy efficiency and reduce emissions.

3. Sustainable Practices

Environmental stewardship is a cornerstone of the Corps’ sustainability agenda. Practices include:

• Zero-Waste Initiatives: At Marine Corps Air Station Miramar, a zero-waste program diverts over 90% of waste from landfills through recycling and composting.
• Green Procurement: Ensuring that supplies, from office equipment to operational gear, meet environmental standards.

In 2023, the Corps reduced single-use plastic reliance by 40% across all installations.

4. Climate-Informed Strategic Planning

Recognizing the security risks posed by climate change, the USMC integrates climate data into its operational strategies.

Examples of Strategic Adaptations

• Arctic Operations: With the Arctic opening due to melting ice, Marines participate in joint exercises like Arctic Edge, preparing for potential conflicts in this region.
• Pacific Operations: Rising sea levels in the Indo-Pacific compel the Corps to support regional partners in climate adaptation efforts, enhancing alliances.

The Climate Assessment Tool developed by the DoD enables the Corps to evaluate climate risks at installations, informing infrastructure investments.

Notable Case Studies

Hurricane Florence (2018)

Marine Corps Base Camp Lejeune sustained nearly $3.6 billion in damage during Hurricane Florence. Post-storm assessments highlighted vulnerabilities, prompting the implementation of a comprehensive resilience plan, including:

• Elevated electrical systems.
• Seawalls to protect against storm surges.
• Renewable microgrids for energy independence.

Combat Energy Efficiency in Afghanistan

During operations in Afghanistan, forward operating bases relied heavily on diesel generators. The introduction of solar power systems in 2012 reduced fuel convoys, frequent targets for insurgents, by 30%.

Challenges

1. Balancing Operational Readiness and Climate Goals

Ensuring combat readiness while investing in long-term climate adaptation remains a delicate balance. Critics argue that green initiatives must not compromise the Corps’ ability to deploy rapidly and decisively.

2. Funding Constraints

Sustainable projects often require significant upfront investments. For instance, transitioning to hybrid vehicles has a high initial cost, despite long-term savings.

3. Interagency Coordination

The USMC collaborates with other military branches and civilian agencies to address climate challenges. However, aligning priorities and resources can be complex.

Future Outlook

The Marine Corps plans to achieve net-zero emissions at installations by 2045, aligning with DoD-wide goals. Emerging technologies, such as hydrogen fuel cells and advanced battery systems, are being tested to reduce operational emissions further.

Additionally, the Corps is exploring partnerships with the private sector for innovations in renewable energy and sustainability.
