Ports worldwide are feeling the heat to become environmentally friendly, whether by transitioning to Net Zero Carbon, reducing emissions, or operating more sustainably. The pressure has only intensified during the Covid-19 pandemic, bringing various issues to light and highlighting the importance of building resilience into terminal operations. 

Over the next three decades, the maritime industry, especially ports and shipping, will have to heed international requirements to become more sustainable in their operations. The challenge for the sector is to meet these obligations while recovering from an economic downturn. Having intelligent and green solutions at the core of port operations provides an opportunity to meet this challenge while maintaining business continuity and economic efficiency while improving container terminal operations.

What are Green Port Initiatives ?

Green Port Initiatives are a set of policy measures and management approaches that help reduce the environmental impact of shipping industries while still helping them remain economically sustainable. They are specifically designed to reduce air and water pollution, tackle noise pollution and energy consumption, and improve waste management. Green port initiatives are mainly driven by the environmental impact of ships and their auxiliary activities (read more about the the "green port concept").

Innovative measures are put in place to reduce the environmental impacts of ports and their activities, resulting in improved overall sustainability. Examples of green port initiatives include introducing cleaner fuels and engines, the implementation of cleaner production methods, and improving waste management procedures. Furthermore, green port initiatives can also involve the adoption of low-carbon technologies, such as wind and solar power, and developing green infrastructure.


Green Port initiatives ask for strategies

While some common practices can be applied, every port has its own set of unique challenges when it comes to reducing emissions and enhancing sustainability. Thus, operators must tailor their approach to their specific circumstances to become smarter and greener. It is crucial to carefully consider the issues and difficulties that may arise along the way to determine the most suitable approach for each individual port.

Transitioning to Green Ports status involves a comprehensive approach encompassing short, medium, and long-term initiatives. To achieve this, developing a Green Ports Strategy is a crucial step as it allows experts in maritime, logistics, and infrastructure to consolidate all challenges and opportunities linked to enhancing the sustainability of operations while considering ongoing obligations and current activities.

Furthermore, a Green Ports Strategy facilitates the discovery of collaborative solutions that can provide numerous advantages, including increased business resilience and preparedness for climate change and disasters.

Here are some of the key areas covered in the development of Green Ports Strategies:

  • Energy efficiency
  • Green Ports Certification
  • Emergency Environment Protection/Disaster preparedness
  • Compliance with international/national legislation
  • Marine water quality management
  • Light and noise pollution management
  • Port Operational Efficiency

By consolidating the various components of a Green Ports Strategy, a systematic approach to investment can be established, laying the groundwork for obtaining external funding. Furthermore, with more international investment organizations demanding proof of sustainable development objectives in the infrastructure projects they support, a sound Green Ports strategy can strengthen the likelihood of accessing additional funding sources and attracting IFI support.


Who carries out green port certifications?

Green port certifications are offered by a variety of organisations, industry associations, and government bodies that specialise in environmental management and sustainability in the maritime sector.

EcoPorts (ESPO)

EcoPorts, the main environmental initiative of the European Sea Ports Organisation (ESPO), offers a comprehensive environmental management and certification program specifically tailored to European ports. Depending on the environmental performance achieved and compliance with the EcoPorts standards, different levels of certification are awarded (bronze, silver, and gold). 

Green Marine

This is a voluntary environmental certification program for ports and shipping companies in North America. It provides ports with a framework for improving their environmental performance. Participating ports undergo annual assessments and self-assessments to track progress.

Port Environmental Review System (PERS)

This program was developed by the International Association of Ports and Harbors (IAPH). Environmental performance and management practices are assessed using various criteria. 

Green Port Initiative (GPI)

It was launched by the American Association of Port Authorities (AAPA) to promote environmental sustainability and best practices in ports in the Americas. While it is not an actual certification program, it provides valuable resources, guidance, and recognition for ports that implement green initiatives and projects.

Other regional and national programs

Several countries and regions have developed their own certification programs tailored to local environmental priorities and regulatory frameworks. One such program is the Green Marine Europe program, which targets European ports. Ports interested in Green Port certification should research and evaluate the requirements, criteria and benefits of various certification programs in advance to determine which one best fits their goals, priorities and operational context.


Green Port Initiatives in Practice

The shipping industry is responsible for a large part of global greenhouse gas (GHG) emissions. As such, it is vital that the sector works to use green port initiatives to help reduce its environmental impact and achieve sustainability. These initiatives include everything from the use of green technology and renewable energy sources to the adoption of sustainable fishing practices and waste management.

Green port initiatives have been implemented at a number of ports across the world in recent years, including ports in the Netherlands, the United Kingdom, Germany, Singapore, and the United States.

"Implementing green port initiatives isn't just about meeting regulations", says Paul Hebrard, Regional Head Asia & Pacific of Identec Solutions, "it's about future-proofing a port's operations. By investing in sustainable technologies and practices, they're not only reducing their environmental footprint but also enhancing operational efficiency and resilience."

In the Netherlands, the Port of Rotterdam is an example of a port that has implemented green port initiatives such as using energy-saving lighting, an energy management system, and modern waste treatment. The port has also invested in new technology, such as RFID reader systems for container tracking and electrically operated cranes. These initiatives have helped the port reduce its carbon dioxide emissions by 14 per cent since 2016.

The Port of Southampton in the UK has implemented eco-friendly initiatives such as air emissions monitoring and reducing the use of sulphur-based fuel. The port has also worked to develop renewable energy capabilities, such as investing in a new wind farm and a battery storage system. The port has also partnered with the UK government to develop a green port program, which focuses on reducing GHG emissions and improving energy efficiency.

Germany’s Port of Hamburg has also implemented a number of green port initiatives, such as using renewable energy sources, investing in electric trucks, and using green construction materials. The port has also implemented a number of waste management strategies, such as using waste heat recovery systems, waste recycling systems, and composting initiatives.

Singapore has also invested in green port initiatives. The Port of Singapore has developed a comprehensive energy efficiency program, which includes energy audits and the use of energy-efficient lighting, pumps, and other equipment. The port has also implemented a number of waste management initiatives, such as using efficient waste collection systems and investing in a zero-waste program.

Finally, the Port of Los Angeles in the United States has implemented green port initiatives such as using clean energy sources, investing in green construction materials, and reducing air and water pollution.

Energy Efficiency Enhancements

The International Maritime Organization has encouraged incorporating green port initiatives into the shipping industry to reduce carbon emissions and to develop more sustainable shipping practices. To this end, several energy efficiency enhancements have been implemented in green port initiatives.

As the maritime industry strives towards sustainability, many ports and shipping lines have already invested in Liquefied Natural Gas (LNG) as a cleaner fuel source. However, with the emergence of new zero-carbon technologies, ports are actively exploring alternative fuels such as hybrid technology and hydrogen to further reduce their carbon footprint.

One of the most commonly used initiatives is the use of shore power. Shore power is when a vessel uses electricity from a port’s power grid rather than its onboard generators while in port. This reduces fuel consumption by cutting off the vessel’s engines and eliminating the need to generate its own energy output. Additionally, it also improves air quality for port cities, as emissions from ships’ generators are a major source of air pollution. As part of a green port initiative, retrofitting vessels to use shore power is a simple yet effective way to reduce emissions and improve energy efficiency.

In addition, initiatives such as shoreside power/cold ironing are being implemented to maximize the connection of ships to the public power grid from the landside during their stay. The ports of the future will also focus on generating their own renewable energy, particularly in solar and wind power.


Waste and Pollution

Green port initiatives focus also on reducing waste created by ships, as well as the release of pollutants into the atmosphere. Such measures include reducing fuel consumption, employing efficient loading/unloading methods, and using advanced waste management systems on ships. Reducing air emissions can be achieved by utilizing more efficient ships, using clean fuels and engines, and installing exhaust gas cleaning systems. Additionally, adopting green port initiatives can improve water quality by reducing the discharge of pollutants, oil, and toxic materials into the ocean.


Greenhouse Gas Emission

The mitigation of GHG emissions is a key benefit of utilizing green port initiatives in the shipping industry. Generally, green port initiatives include a set of environmental protection and sustainability policies that emphasize low-carbon transportation and shipping operations. These policies often involve introducing green technologies, practices and regulations which reduce the amount of emissions from vessels during port operations. By encouraging the use of greener technologies, vessels can significantly reduce their emissions, leading to long-term decreases in emissions released into the atmosphere. Additionally, implementing green port initiatives can result in the usage of cleaner fuels and energy sources, thus leading to a further reduction in emissions.
