(SeaPRwire) –   TAIPEI, May 4, 2026 — CTCI Corporation, dedicated to its role as a “Guardian of Sustainable Earth,” today announced it has once again secured the top position for sustainability performance among global construction and engineering firms in the S&P Global Corporate Sustainability Assessment (CSA) with a score of 89. This marks the fourth consecutive year CTCI has held the number one spot. This consistent excellence has led to the company’s inclusion in the Dow Jones Best-in-Class Emerging Markets Index for the 11^th year in a row, alongside recognition as a Top 1% global performer in the S&P Global Sustainability Yearbook 2026. These achievements underscore how sustainability is central to CTCI’s competitive advantage and establish the firm as a reference point in the worldwide shift to net zero emissions.

“Securing the number one ranking year after year in the global engineering and construction industry is a powerful affirmation of CTCI’s enduring dedication to ‘Green Engineering,’” said CTCI Group Chairman John Yu. “As a Guardian of Sustainable Earth, CTCI has emerged as one of the most dependable strategic partners for clients globally in driving energy transition and low-carbon development. We hold that engineering is about more than constructing for the present; it is about establishing the groundwork for a resilient future society. To this end, CTCI weaves sustainability into every phase of a project’s lifecycle—from initial design through to operation and maintenance—using advanced, intelligent, and green technologies to turn sustainability goals into concrete technical results. In this way, CTCI not only assists industries in reaching net zero objectives but also effectively channels the global green transformation into a significant catalyst for the company’s sustained growth.”

CTCI continues to gain substantial acclaim in the international engineering market, supported by its robust engineering, procurement, and construction competencies and precise market focus. Since 2015, the value of CTCI’s green engineering projects has surged by 753%, with total investment surpassing NT$45.4 billion, highlighting vigorous growth. In step with global trends in decarbonization and sustainable infrastructure, CTCI has cultivated specialized knowledge in complex sectors, allowing it to build a formidable global portfolio in LNG receiving terminals and gas-fired power plant construction. This has solidified its leading role in Taiwan while extending its international presence. Furthermore, CTCI is actively progressing liquids-to-chemicals projects in the Middle East, the United States, and Southeast Asia to seize new opportunities arising from the low-carbon shift. To adhere to the demanding timelines of high-tech facility construction, CTCI utilizes its global resource coordination and vast international project management know-how to guarantee timely, high-standard project completion, acting as a trustworthy ally for clients’ worldwide growth.

Technologically, CTCI is speeding up its digital evolution by implementing its in-house “CTCI Digital Twin” and “CTCI AI Smart Platform.” These tools merge decades of engineering know-how with intelligent technology to create precise cloud-based simulations of the entire project lifecycle. This approach allows CTCI to convert decarbonization obstacles into chances for efficient operation and maintenance. The company is also making strategic investments in promising areas like carbon capture, utilization and storage (CCUS) and water reclamation. CTCI has not only finished Taiwan’s inaugural national-scale CCUS net-zero initiative but has also refined its world-leading water reclamation system—first used at the Southern Taiwan Science Park Water Reclamation Plant—into a standardized solution that allows industrial wastewater to be purified for reuse in semiconductor manufacturing. By providing tailored solutions, CTCI assists clients around the world in tackling both water shortage and carbon reduction issues, generating mutual benefits for business and the ecosystem.

As a worldwide sustainability frontrunner, CTCI advocates for “Total Participation in ESG Implementation,” mobilizing its entire global team to amplify the positive impact of its engineering work. The company has delivered exceptional results in climate governance and supply chain collaboration, receiving dual “A List” scores from CDP. It has also been acknowledged as an early adopter of the Taskforce on Nature-related Financial Disclosures (TNFD) for its work in biodiversity conservation and zero-deforestation measures within project delivery. Concurrently, CTCI persistently enhances talent cultivation through platforms like CTCI University, CTCI Learning, and the CTCI Education Foundation. CTCI has also formed a Supplier Alliance for Net Zero Emissions, urging its supply chain collaborators to jointly boost industry competitiveness via sustainable practices. On the journey to net zero emissions, CTCI will persist in leading with its top-tier engineering capabilities, forging a more sustainable future.
