Sustainable Bonds and Sukuk: International Case Studies

What can a Malaysian business learn from international sustainable-finance transactions? Start with two questions: where must the money go, and what must the borrower demonstrate afterwards? Different structures answer those questions differently, even when their names refer to the same sustainability goals.

Review and source dates

This page revisits a historical webinar and uses original issuer documents to explain practical lessons. Sources reviewed: 5 October 2026. These are historical examples, rather than offers of financing.

The original webinar and the limits of its archive

The historical Malaysian Sustainable Finance Initiative (MSFI) held Sustainable Projects that can be Funded Through Bonds & Sukuk on 1 April 2021. A participant's training record in MISC Berhad's Integrated Annual Report 2021, printed page 238 independently confirms the date, title and organiser.

The historical recap identifies it as a virtual event and names contributors from EY Malaysia, IISD, BTS Group, Enel, ANZ and the City of Cape Town. We could not find a complete recording or set of presentations. Instead, the examples below come from original documents issued by the named organisations; they do not attempt to reconstruct what individual speakers discussed.

This independent website did not organise the event and does not claim the original initiative's partnerships.

BTS Group: follow the allocation, including refinancing

BTS Group Holdings' Green Bond Report 2020, using data at 31 March 2020, records five portions of the green-bond financing, known as tranches. They were issued on 24 May 2019 and totalled THB13 billion. The report records THB6.5 billion allocated to each of Bangkok's MRT Pink and Yellow Lines, with the allocation identified as 100% refinancing.

Refinancing replaces funding for spending already incurred; it should be distinguished from money paying for new expenditure. Here, the report identifies the assets and allocates each tranche between them. That is more informative than a broad claim that the issuer supports clean transport.

For your own proposal, keep a schedule connecting eligible invoices and project costs to the financing. If you include earlier expenditure, explain the period covered and the treatment agreed with the financier. An allocation report shows where funds were assigned; it does not by itself prove that emissions fell.

Enel: a target changes the financing terms

Enel's announcement of 6 September 2019 describes a USD1.5 billion bond launched by Enel Finance International NV, with settlement set for 10 September 2019. The proceeds were for ordinary financing needs, while the interest terms depended on a sustainability target.

Enel's target was for renewable sources to make up at least 55% of the group's total consolidated installed generating capacity by 31 December 2021. If it was missed, the announcement specified a 25-basis-point interest-rate increase—0.25 percentage points—following the auditor's assurance report.

This illustrates performance-linked financing: a contractual measure and consequence, rather than a requirement to allocate all proceeds to particular green assets. The launch announcement describes the design, but does not say whether the target was subsequently achieved.

When examining a similar structure, ask how the measure is calculated, which entities it covers, when it is tested, who verifies it and exactly how financing terms change.

ANZ: a bank can finance a portfolio of eligible activities

ANZ's 14 February 2018 announcement records its first €750 million, five-year Sustainable Development Goals bond. It said the proceeds would fund loans and expenditures supporting nine UN Sustainable Development Goals, with intended activities including hospitals, schools, green buildings, clean water, public transport and renewable power.

The bank acts as an intermediary between bond investors and underlying financing. For a business, the useful question is whether its project fits a bank's eligible portfolio and lending requirements. The announcement alone does not confirm that all funds were allocated, show how the projects performed or make a Malaysian borrower eligible.

Ask the bank which evidence it needs from you and how your financing would be monitored within its portfolio.

Cape Town: later reporting guidance adds a practical lesson

The City of Cape Town's Green Bond Reporting Framework is Version 1, dated 23 September 2021, and is available through the City's document directory. It was published after the April webinar and is included as later context.

It separates financial reporting from impact reporting and describes tracking project budgets, disbursements and funding sources. It also addresses exceptions, including changes requiring review and possible reallocation of funds.

For a chief financial officer (CFO), that suggests a useful operating discipline: agree the reporting process before financing is raised. Keep spending records and sustainability measures connected, while recognising that they answer different questions. Set responsibilities for identifying a project change and telling the financier how it will be handled.

Applying the lessons in Malaysia

Across these examples, the useful distinction is between eligible spending, contractual targets, and evidence after financing. A project list, a target announcement and evidence of achieved results answer different questions.

Use our green, social and sustainability bonds guide to understand use-of-proceeds financing, and sustainability-linked financing for performance targets. For an Islamic financing route, read the SRI Sukuk Framework guide and green and SRI sukuk guide.

An SME can apply the same evidence discipline to a bank proposal without issuing bonds or sukuk itself. Start with financing readiness: define the activity, cost, repayment source and records you can maintain. Then discuss an appropriate financing route with the provider.
