Green port logistics-Sailing toward a low carbon shipping
Recent geopolitical tensions and conflicts in major oil-producing regions have reduced crude oil availability, disrupting supply chains and driving up fuel costs. Post-pandemic economic recovery has exacerbated the situation, with surging energy demand outpacing supply and causing prices to spike. In addition, governments have imposed stricter environmental regulations and carbon taxes to encourage the shift toward sustainable energy sources.

As climate change and environmental degradation become more pressing concerns, consumers and businesses are increasingly demanding greener supply chains. Adapting to these challenges, the global maritime industry is pivoting toward green port infrastructure as a key solution.
Green ports significantly reduce emissions and enhance operational efficiency, helping to mitigate the industry’s impact on the planet while meeting the growing demand for sustainable practices. They integrate eco-friendly technologies and practices such as shore power systems, emissions-reducing innovations, and renewable energy sources like wind and solar power. For this to become the new norm, collaborative efforts among port authorities, shipping companies, and stakeholders are crucial.
With shipping responsible for 11 percent of life cycle carbon emissions in transportation, the push toward greener ports plays a vital role in reducing the industry’s overall carbon footprint.
Plugging into progress: the shocking truth about shore power
Originally, ports relied heavily on auxiliary engines running on fossil fuels to power ships while docked. These engines, however, emit significant amounts of pollutants, leading to demands for cleaner operations, especially in major port cities.
Shore power systems, known colloquially as cold ironing or alternative maritime power (AMP), reduce emissions from docked vessels at port. Ports worldwide, notably in Singapore and Shanghai, have significantly invested in shore power infrastructure to accommodate vessels calling at their terminals.

With shore power, vessels plug in to onshore electricity grids and do not have to use their auxiliary engines to generate power, reducing emissions and noise levels.
With shore power, vessels plug in to onshore electricity grids and do not have to use their auxiliary engines to generate power, reducing emissions and noise levels.
By interfacing ships with electrical grids, these vehicles are connected to land-based electrical grids while docked and idle. Berthed ships can turn their auxiliary engines off and transition to onshore electric power, reducing air pollution by up to 95 percent.
In this way, shore power systems significantly mitigate air pollution in port areas and enhance local air quality, contributing to the sustainability of port operations. Noise levels are also reduced, and local air quality is greatly improved.
The port of Hong Kong, the eleventh busiest container port globally, experiences severe air pollution. When Hong Kong shelved its shore power project, protestors pointed out that shore power could reduce the lives lost to air pollution, and even lead to annual savings of HK$523 million (€61 million). Still, the project was deemed too expensive to follow through with. As it is, the port city still faces unhealthy levels of air pollution.

Implementing shore power infrastructure in the port of Sydney improved the air quality in surrounding areas near the port.

The port of Sydney also faced backlash over air pollution caused by cruise ships and other vessels running their auxiliary engines while in port. Residents reported health issues linked to poor air quality, which pushed authorities to take action. Sydney responded by installing shore power infrastructure and enforcing stricter environmental regulations, leading to a noticeable improvement in air quality.

Harnessing solar and wind power for smooth sailing
Exploring renewable energy systems or hybrid systems that combine solar, wind, and hydroelectric power with complementary technologies can also help to increase energy resilience and minimize logistics disruptions.
By drawing on solar and wind power, ports possess greater energy independence as electricity is generated on-site, reducing reliance on external sources and ensuring a stable energy supply. This is especially crucial during periods of volatility or disruptions in traditional energy supply chains.
Alternatively, microgrid solutions offer localized energy systems that operate autonomously or alongside the primary grid, enhancing resilience during outages and emergencies while promoting energy independence and sustainability.
The Qingdao port in China and Brisbane port in Australia have invested in extensive solar panel installations across their terminals, leveraging the region’s abundant sunlight. Qingdao’s bridge cranes utilize photovoltaic (PV) systems to generate up to 500,000 kilowatts of energy annually, across 2,800 square meters of PV panels. Similarly, Brisbane has an 800-kilowatt rooftop solar system that provides a shaded car park and produces 1300 megawatts of power annually.
These installations, in turn, reduce operational costs and reliance on conventional harmful energy sources such as fossil fuels, bringing them one step closer to their sustainability goals. For Brisbane, this has translated into the port meeting its net zero carbon emissions goal only three years after the commencement of its renewable energy journey, putting it six years ahead of its initial goal of 2030.
Green port logistics-Sailing toward a low carbon shipping – Ports experiencing favorable windy conditions also draw on wind turbines to bolster their renewable energy capacity. The Yokohama port in Japan and the Kaohsiung port in Taiwan strategically deploy wind turbines to supplement their energy needs and contribute to their sustainability objectives. These wind turbines also similarly generate electricity that can be seamlessly integrated into port operations or channeled into the grid, further reducing reliance on fossil fuels and mitigating carbon emissions.
These initiatives are paving the way for the Yokohama port to achieve carbon neutrality by 2050, aiding Japan in establishing a planned green shipping corridor with Singapore as the two countries tap into each other’s technologies to further decarbonize the industry. The hope is to develop a similar corridor between Kaohsiung and North America, which depends heavily on inter-port low-carbon facilities and clean energy resources.

Energy storage solutions like battery storage systems complement intermittent renewable sources. On-site battery storage allows surplus solar energy to be stored and discharged during peak demand or when renewable energy is unavailable, ensuring grid stability and uninterrupted operations.
Charting a course through cost and regulatory barriers
Renewable energy transitions are about more than just cutting emissions and improving efficiency for logistics operations. They are a statement, showcasing a company’s dedication to corporate social responsibility and environmental stewardship, resonating with stakeholders and consumers.
By tapping into solar and wind power, ports gain a newfound energy independence, ensuring a reliable energy supply even during disruptions. Microgrid solutions offer an extra layer of resilience, crucial during emergencies. Investing in renewables saves costs in the long run and strengthens financial sustainability. And with options like power purchase agreements (PPAs) and green bonds, overcoming adoption barriers becomes more manageable, paving the way for a smoother transition toward a greener future.
Governments in the Asia Pacific region are quick to set up renewable energy sources to assist companies in adopting clean energy. Japan’s Feed-in Tariff (FIT) scheme guarantees fixed prices for renewable energy, while Singapore’s Green Port Program incentivizes vessels that use cleaner fuels or adopt green technologies, pushing for the use of renewable energy sources. These not only drive compliance with carbon emission goals, but also foster innovation and investment in renewable energy infrastructure within ports.
Green port logistics-Sailing toward a low carbon shipping – Emerging carbon pricing mechanisms like China’s pilot carbon trading programs may push more logistics companies toward renewable energy investments. These blockchain-enabled energy trading platforms empower logistics companies to participate in local energy markets, monetize excess renewable energy, and support community-based initiatives. Regional targets, such as India’s goal of 500-gigawatt renewable energy installed capacity by 2030, guide logistics companies in aligning with national priorities.
Measuring the waves from carbon footprints to carbon savings
For logistics companies to effectively address the environmental impact of their operations, they must first quantify it. This involves measuring and managing carbon emissions, energy consumption, and waste generation within green ports and maritime logistics. Logistics companies can utilize advanced data collection systems and analytics to monitor key environmental performance indicators by employing tailored metrics and methodologies.
This includes tracking greenhouse gas emissions from transportation, energy usage in facilities, and waste generated throughout the supply chain. By accurately measuring these metrics, these companies gain insights into their environmental footprint and identify improvement opportunities.
Life Cycle Assessments (LCAs), for instance, analyze environmental impacts across a product’s life cycle, aiding companies in identifying hotspots, assessing sustainability initiatives, and minimizing their footprint. Logistics companies conduct LCAs to evaluate the impact of renewable energy investments, from manufacturing to decommissioning.
Environmental Certification Schemes like ISO 14001 and LEED provide standardized frameworks evaluating energy efficiency, resource conservation, and waste management. Logistics companies can undergo audits to achieve ISO 14001 certification, signifying adherence to environmental management standards.
The transformation of port infrastructure through the integration of renewable energy and shore power systems is a pivotal step toward sustainability. By quantifying environmental impact and embracing best practices, ports worldwide set new standards for sustainability and operational efficiency, paving the way for a greener maritime industry.

Decarbonizing from end to end
Companies that have started or are starting their sustainability journey need to take a long, hard look at their decarbonization strategy.
Companies that have started or are starting their sustainability journey need to take a long, hard look at their decarbonization strategy.
Decarbonization begins with reducing carbon emissions within their control, either directly or indirectly.
But decarbonizing aspects beyond their control is the key to a successful sustainability strategy. A report by Accenture has noted that the supply chain generates 60 percent of all carbon emissions globally. Thus, there is an urgent need to focus on decarbonization in the logistics network to achieve emissions reduction targets.
Companies need to establish a clear understanding of where carbon emissions lie along the supply chain, and through that, set their decarbonization targets. Understanding the carbon footprint, setting reduction targets, optimizing the supply chain, switching to sustainable fuels, and adopting technology are key steps to decarbonization.
With a better understanding of how to decarbonize both the direct and indirect aspects of their end-to-end value chain, companies can set a clear decarbonization roadmap to achieve their net-zero carbon emissions targets that align with the Science Based Target initiative.

Green port logistics-Sailing toward a low carbon shipping – Going full circle with circularity
Circularity is a key aspect of sustainability that focuses on creating a closed-loop system where resources and waste are minimized, and materials are continuously repurposed or recycled.
Circularity is a key aspect of sustainability that focuses on creating a closed-loop system where resources and waste are minimized, and materials are continuously repurposed or recycled.
According to the Ellen MacArthur Foundation, only 8.6 percent of the global economy is currently considered circular. However, transitioning to a circular economy could bring significant benefits. For instance, a report by Accenture estimates that circular economy practices could generate US$4.5 trillion (€4.2 trillion) in economic benefits by 2030.
Circularity involves designing products with efficient processes such as better packing practices and promoting the reuse of materials in packaging. The former has an almost immediate impact, as reducing empty space in packages means less boxes, and thus filling materials used. Companies can also switch from normal to pre-stretched pallet wrap, which has a significant effect in reducing the plastic intake by half.
Green port logistics-Sailing toward a low carbon shipping – According to the World Economic Forum, if all plastic packaging was made from recycled materials, it could save up to 30 million tons of carbon emissions per year.
Optimizing sustainability through digitalization
Digitalization plays a crucial role in promoting sustainability by integrating digital technologies and data-driven approaches to optimize processes, enhance efficiency, and enable informed decision-making.
Green port logistics-Sailing toward a low carbon shipping – Digitalization plays a crucial role in promoting sustainability by integrating digital technologies and data-driven approaches to optimize processes, enhance efficiency, and enable informed decision-making.
By adopting digitalization, companies can deploy smart systems to monitor and manage energy consumption, optimize supply chains, and facilitate sustainable practices. Leveraging digital technologies, for example, can identify energy-saving opportunities, optimize operations, and improve energy efficiency.
Organizations can use advanced analytics and machine learning algorithms to optimize energy usage in buildings, reduce energy waste, and lower carbon emissions. This applies to the supply chain perspective too, ranging from warehouses being able to reduce energy usage to optimizing the last-mile delivery route to reduce fuel consumption.
Cleaning up the act with green energy
Clean energy, including renewable energy sources such as solar, wind, hydroelectric, and geothermal power, is a crucial component of sustainability.
Clean energy, including renewable energy sources such as solar, wind, hydroelectric, and geothermal power, is a crucial component of sustainability.
Transitioning to clean energy is essential for reducing greenhouse gas emissions, mitigating climate change, and achieving a sustainable energy future.
According to the International Renewable Energy Agency (IRENA), renewable energy accounted for 72 percent of global power additions in 2019. The falling costs of renewable technologies have contributed to their rapid adoption. For instance, the cost of solar photovoltaic (PV) panels has decreased by 82 percent over the past decade, making it one of the most cost-effective sources of electricity generation.
Green port logistics-Sailing toward a low carbon shipping – On the logistics front, solar panels and LED lighting have become key considerations when upgrading or building new warehouses. In the United States (U.S.), the flat and open roofs of medium and large warehouses and distribution centers are perfect locations for solar panels. With more than 450,000 such buildings, totaling almost 16.4 billion cumulative square feet of rooftop space, the solar power potential is enormous. In fact, the rooftops of American warehouses built before 2019 have the capacity to generate 185.6 terawatt-hours (TWh) of solar electricity each year, enough to power almost 19.4 million average homes.

Deploying clean energy such as sustainable aviation fuel (SAF) for transportation to reduce carbon emissions is also a key driving force for sustainability. “70 percent of our customer’s emission are on average related to aviation, so SAF will play a key role. The nice thing with solutions such as SAF is that there is no risk of path dependency. This product can be switched on and off flexibly and does not require upfront investments,” added Schwarz.
Driving the sustainability bandwagon with clean mobility
Clean mobility involves sustainable transportation options that minimize carbon emissions and reduce dependence on fossil fuels.
Clean mobility involves sustainable transportation options that minimize carbon emissions and reduce dependence on fossil fuels.
Transitioning from traditional gasoline-powered vehicles to electric vehicles (EVs), promoting public transit systems, and encouraging cycling and walking are all part of clean mobility initiatives.
The IEA projects that the number of electric cars on the road could reach 145 million by 2030. This shift towards EVs is crucial for reducing transportation emissions and improving air quality. A study by the University of Michigan noted that a battery-powered pick-up, from manufacturing to operating the EV, . While there are steps taken to reduce the upstream carbon emissions from manufacturing the EVs, it is important to note that the operation of EVs, powered by renewable energy, will have zero carbon emissions.
Investments in charging infrastructure are also crucial for the widespread adoption of EVs. The Global EV Outlook 2021 reports that there were over 7.3 million electric vehicle chargers worldwide by the end of 2020, including both public and private chargers. The growth of charging infrastructure supports the convenience and accessibility of EVs, further accelerating the transition to clean mobility.
Companies that proactively seek out partners to address sustainability risks, such as resource scarcity and regulatory changes, are better positioned to adapt and thrive in an evolving business landscape. “Once partners have talked to each other, it is important to quickly act and roll out pilot programs to learn. Deploy an EV for a certain lane, use SAF for a particular destination, and the like,” noted Schwarz.
Beyond the economic aspect, taking the sustainability route has a positive brand effect for companies, especially with the increasing awareness of consumers. By embracing circularity, digitalization, clean energy, and clean mobility, businesses can make significant progress toward a more sustainable future.
