Singaporean innovator brings green tech to maritime industry
FROM virtual reality learning to world-class simulators and autonomous ships, digital technology has been the driving force behind the 21st century evolution of international shipping. This development is taking the world’s maritime industry by storm, demanding urgent upskilling of shore and sea-based workforce, modernization of ships, and realigning of processes. Unlike fuel-powered ships, however, it is rare that people ask whether technology poses harm to the environment. This was the exact concern of Ian Chew, founder of Greenie Web, the award-winning Singapore ClimateTech that creates low-carbon computer code. He is lauded for being a pioneer in the decarbonization of digital world, and the first in Asia to carry out such work. The idea first came to Chew during his computer class back in high school. The then 13-year old asked whether technology could harm the environment, a small question that infuriated his teacher. This episode only sparked the curiosity of Chew and led him to one research to another until, years later, he developed a digital system that is environment friendly. “I could not stop thinking of how big a problem it could potentially be. Increased technology adoption would lead to increased energy consumption, which will rely on increased oil and gas extraction. With the general direction in Singapore and across the world pointing towards an accelerated rate of technology adoption, I knew I had to do something,” the young Singaporean said. The creation of Greenie Web in 2009 started as Chew’s personal project with a basic principle of having an environmentally-friendly and low-carbon computer code. A 2024 sustainability article published by FedEx revealed that around 5.45 billion people globally are connected to the internet. The advent of online businesses, remote working, and digitalization are responsible for a major increase in carbon emissions. In the last five years prior to the article publication, it was revealed that Google’s emissions have jumped by almost 50 percent as they scale up their use of AI web technology. In the maritime industry, it is estimated that more than 940 million tons of carbon dioxide emissions are emitted by ships. As the industry leans into digitalization, CO2 emissions are expected to further surge. When Chew started working for a Singaporean maritime organization that carries out Ultrasonic thickness measurement (UTM), a nondestructive testing method used to inspect the metal thickness of ship hulls, piping and structural steel, he realized how the sector can greatly benefit from green technology. “The maritime industry stands to benefit significantly from green technology because it improves both environmental sustainability and operational efficiency. Innovations such as cleaner fuels, electrification, digital optimization, and energy-efficient vessel design can reduce emissions while also lowering long-term operating costs for shipowners. “At the same time, digital technologies, including AI, data analytics, and smarter software systems, can help optimize routes, reduce fuel consumption, and improve overall fleet performance. As the industry becomes increasingly digitalized, there is also growing attention on digital sustainability. Concepts such as green AI and low-carbon computer coding aim to ensure that the software and digital infrastructure supporting maritime operations are themselves energy-efficient, reducing the overall environmental footprint of rapidly scaling digital systems,” Chew explained. He added that that as global regulations tighten and customers increasingly expect greener supply chains, adopting green technologies will help maritime companies remain competitive and future ready. “Ultimately, green technology is not just about compliance; it represents an opportunity for the maritime sector to modernize, innovate, and play a leading role in the global transition toward a more sustainable economy,” he said. Despite the anticipated reluctance of industries to adopt green technology, Chew remains confident that the global momentum toward sustainability will continue to grow. “As the effects of climate change become increasingly visible, policymakers, businesses, and individuals are recognizing the importance of integrating sustainability into technological development. “Knowing that the ideas and solutions we develop today may contribute, even in a small way, to a more sustainable digital future for the next generation is what gives me the greatest sense of purpose in this work,” he said. Outside of his digital advocacies and behind his public persona, Chew is a young man who values peace and quiet. He spends a lot of time reading, researching, and reflecting how to help resolve long-term problems. “I am someone who values humility and faith, and I try to stay grounded despite the opportunities I’ve been fortunate to receive,” he shared. Like most Filipinos, Chew came from a close-knit family from Singapore. “My biggest inspiration is my mother. She has always been a quiet example of strength, perseverance, and selflessness. Growing up, I saw how much she sacrificed for our family and how she approached challenges with grace and determination. Those lessons continue to influence the way I approach both life and work,” he added. “My parents have always been very supportive of my work. Their emphasis on education, responsibility, and contributing positively to society has strongly influenced my journey in sustainability and entrepreneurship,” he concluded.
