The Ports of Tomorrow

From Ruin to Renewal: Busan and The Making of Tomorrow’s Sustainable Ports

By The Change Lab

Never before has climate change held such a profound relevance for the global community as it does today. The challenges caused by climate change resonate deeply with our shared global future, threatening the very survival and resilience of our cities. By increasing the number of extreme weather events such as flooding and heatwaves, it puts pressure on cities’ infrastructure and services which are not designed to cope with these new extremes. These issues are exacerbated in port cities.  In recent years, port cities around the world faced unprecedented challenges to develop sustainably as they must respond to increased environmental awareness, greater social responsibility, and the ever-lasting quest for sustainable economic operations. 

Traditionally, the major levers of green port development were concentrated in Europe, particularly amongst the 1997 EcoPorts ‘prime partners’ such as Amsterdam, Barcelona and Bristol. The certification system they’ve created-the port environmental review system- has since evolved into a de facto benchmark, shaping port governance and trade practices well beyond that of Europe. 

However, the strategic challenge of developing advanced green port technology increasingly drew in stakeholders from other continents, eager to shape the future sustainability agenda; one of such stakeholders is Korea. Thus whilst the Port of Long Beach, Los Angeles, was winning the AFSC hosted ‘Best Green Seaport’  award in 2025, on the other side of the world, South Korea engaged with its own sustainable port development: the Port of Busan. Busan, a major port city in East Asia, has quietly become a test bed for sustainable port activities and it is teaching coastal cities one simple lesson: plan now for future climate risks or there shall be escalating environmental and economic consequences.

   Historically, South Korea was widely known for its political turbulence and economic stagnations. In the early 1960s, South Korea was close to being considered a failed state. Exports accounted for less than 1% of total GDP and South Korea could only afford imports of about 10% of GDP as a result of foreign aid from the United States. Trade expansion in South Korea only began during the period of Japanese occupation, a period of history that many South Koreans will now recall with horror. Whilst it is certain that the Japanese military oppressed political rights, destroyed traditional Korean cultures and carried out violence on a large scale, it also simultaneously fostered an expansion of trade and commercial networks. With the Japanese settling at the Port of Busan, it became Korea’s first international port in1876. The Japanese developed the modern port and transportation routes to Japan, China, and Russia whilst building large warehouses and introducing new industries such as fishing and shipbuilding to increase economic prosperity in Busan and surrounding regions. Today, Busan is one of the busiest ports in Asia with more than 20 million TEUS being handled annually. It has become a vital hub of international trade within East Asia and beyond. Busan’s emergence as a trade hub was catalysed by the very power that once tyrannised Korea. However, like all modern ports, Busan faces a distinctly 21st-century threat: climate change. There’s no doubt that it is an issue that needs to be addressed , and it is undeniable that Busan is addressing it in an unparalleled way: by two projects unique to Busan but designed to be replicated globally

   Indeed, Korea has experienced rapid economic growth and the port of Busan will soon prove itself to be a world-leading mega port. The Busan Port Authority(BPA) completed two innovative projects in 2022: ‘Piezoelectric Power Generation System’ and the ‘Construction Wastes Recycling Project’; both are to solve growing concerns about environmental pollution and exhaustion of resources. The first project uses harvesting modules to convert and store electric energy from the pressure  caused by the wheels of trucks passing above the system. The modules are to be installed at all 47 terminals and is expected to reduce CO2 emissions by 936.522 tCOSeq annually: equivalent to planting 150000 pine trees. This strategy is highlighted internationally as a novel first-of-its-kind port application, transforming a traditionally harmful environmental practice into one that heals our planet.  The second project seeks to reduce waste by establishing a resource circulation system that reuses waste for the port construction process. This will lead to a budget reduction of 4.06 billion KRW and an additional 7.6 billion KRW benefit for the environment. 

   Busan is word-leading for the large-scale use of innovative green technology, integrated into a full net-zero strategy rather than just a small demo. The 21st century’s most threatening global risks-climate change and superpower rivalry-are faced by and concentrated in ports. Yet globally, many ports are still following a growth model that assumes weak climate regulation and a linear construction or failing in infrastructure; they fail to balance stability against progress. Busan offers perhaps the best example on how a struggling port can guide itself into becoming a global leader in sustainable port development. 

    Busan’s system as an innovative best practice is something that other ports can replicate, because it uses universal conditions-heavy truck flows and large amounts of waste-rather than resources unique to South Korea. The BPA plans to share the gained outcomes of these projects to domestic and foreign ports alike, enhancing the capacity of ports worldwide to withstand the threats of climate change in the 21st century. But the benefits are far from over. The projects will reduce air pollution from fossil-fuel and lower health risks for residents and port workers alike; research has shown that a clean environment improves our mental health. This makes Busan both a safer and more jovial place to live. Both projects create demand for novel types of jobs which can support local communities in employment and green-skill development. This helps us to have a young generation who is aware and actively engaged in solving ‘an environmental, social, and ethical issue of the world’. 

     Nonetheless, the plan is not free of problems. As mentioned before, Busan’s projects are at the forefront of sustainable port development and thus there was no established governing body to regulate the use of recycled aggregates in construction. This has already raised social concerns about the risks of contaminants and mixed sources that will make the construction of a poor quality that fail to meet standards. It is ultimately the BPA’s responsibility to ensure that regulation is strictly enforced to Busan port and quality management of aggregate is considered to be of utmost importance. The BPA should also maintain transparency on how quality is regulated whilst listening for complaints and feedback from the public so they feel heard and protected. 

     With effective management and continued global collaboration, Busan is well placed to become the next world leader in sustainable port development and shape the future of global port systems. If ports around the world can emulate Busan’s innovation and ambition, we will be significantly better positioned to foster novel solutions to confront the climate crisis that’s threatening the future of our species.
