CT AWARDS SPOTLIGHT 2026: E.SUN Bank

From sustainable bonds and transition loans to offshore-wind financing and interest-rate hedging, E.SUN Bank is helping clients put their climate and transition plans into practice.

Its two award wins recognise different sides of that work. The regional award reflects the scale and breadth of E.SUN’s sustainable finance business, while the ‘Best Treasury Sustainability Initiative’ award highlights its ability to develop practical solutions for individual sectors and clients.

In particular, the first award recognises a broad range of capabilities that combine sustainable funding, investment, lending and advisory capabilities. In 2025, E.SUN’s sustainability-linked loan balance reached NT$104.8 billion ($3.3 billion), exceeding its NT$80 billion target, while green loans rose to NT$137.5 billion, ahead of the NT$124 billion goal. Its sustainable bond investments reached NT$121.2 billion, 2.8 times the previous year’s level and well above its NT$48 billion target.

E.SUN has also become Taiwan’s largest sustainable bond issuer among financial institutions, with cumulative issuance of approximately NT$29.8 billion. Between June 2025 and June 2026, for example, it issued NT$2.31 billion of sustainability bonds, with proceeds directed to areas including renewable energy and energy technology, healthcare access and socioeconomic development. By February 2026, all proceeds had been allocated to eligible investments and lending.

This balance of funding and deployment is reinforced by client-facing innovation. E.SUN acted as lead underwriter for a 500MW offshore wind syndicated loan in 2025, supporting renewable generation as well as local supply-chain participation.

Its renewable energy financing balance reached almost NT$95 billion, 2.8 times its 2022 baseline, while cumulative wind and solar installations financed by the bank helped avoid an estimated $435 million in social carbon costs.

At the same time the ‘Best Treasury Sustainability Initiative’ highlights how E.SUN is moving beyond conventional green labels towards transition-focused finance.

The bank’s flagship ESG Sustainability Initiative, launched in 2021, has developed into a collaborative platform involving companies, policymakers, healthcare institutions, academics and technology organisations. As early as 2022, participating companies represented more than a quarter of Taiwan’s GDP by combined revenue.

Central to the initiative is E.SUN’s “Talent × Technology” approach. It combines specialist ESG advisory support with internal tools including a carbon-emissions management system, a sustainable investment evaluation model and tailored low-carbon transition frameworks. A proprietary seven-tier maturity model, benchmarked against EU, ASEAN and Taiwan taxonomies, helps the bank identify which parts of a client’s business are already aligned, actively transitioning or still require structured support.

That approach has produced several market firsts. In January 2026, E.SUN arranged a “Resilient Healthcare” sustainability-linked loan for Koo Foundation Sun Yat-Sen Cancer Center. By using the nurse-to-patient ratio as a sustainability performance target, the facility linked financing incentives directly to workforce resilience, patient safety and continuity of care.

Later that month, the bank structured Taiwan’s first transition loan for the passenger transport sector for Metropolitan Transport Corporation. The loan connects pricing to verified milestones supporting the electrification of its urban bus fleet. E.SUN also extended sustainable finance into risk management: a new NT$5.1 billion interest-rate swap for an offshore wind project brought its cumulative sustainable project hedging volume to roughly NT$53.5 billion, helping protect long-duration project cash flows from rate volatility.

Taken together, these awards show the breadth of E.SUN’s approach. The bank is providing capital, but it is also helping clients assess where they stand, set realistic transition milestones and manage the financial risks involved. This makes its sustainable finance offering particularly relevant to companies moving from broad commitments to practical, measurable action.

“E.SUN actively targets 'parts of the business currently in transition' to spearhead value chain transformation,” said Joseph N.C. Huang, Chairman of E.SUN FHC. “Rather than excluding high-carbon industries, E.SUN strategically deploys the transformation maturity rating mechanism to actively guide and accelerate enterprises in 'upgrading step-by-step'.”
