Sri Lanka’s green bond market has moved from a single sovereign issuance to a pipeline of corporate and multilateral instruments. ESGNexus assesses where the market stands at mid-2026, what is working, and what is holding it back.

Sri Lanka’s green bond market entered 2026 with more institutional infrastructure than it had twelve months earlier but a relatively thin track record of domestic corporate issuance. The market’s development has been constrained by three factors: the economic crisis of 2022-2023 that reduced risk appetite across capital markets, the absence of a domestic green finance taxonomy, and limited demand from domestic institutional investors.

The sovereign green bond programme demonstrated that international appetite for Sri Lanka green instruments exists at the right terms. The challenge has been replicating that appetite at the corporate level, where due diligence demands are higher, instrument sizes are smaller, and issuer ESG disclosure quality is more variable.

What international institutions are doing

International development finance institutions have been the most active participants in building Sri Lanka’s green finance market. IFC has supported sustainable banking initiatives through credit lines to Sri Lankan banks specifically for on-lending to eligible green projects. The Asian Development Bank has maintained a programme of climate finance support.

CBSL’s Sustainable Finance Roadmap 2.0 was developed in partnership with IFC’s technical assistance programme under the Sustainable Banking and Finance Network, giving it international credibility and connecting it to global best-practice frameworks. These DFI instruments have established the precedent that green finance instruments can be structured and executed in the Sri Lankan market, and built the relationships between international capital and local financial institutions necessary for market development.

The taxonomy problem — and its solution

The most significant structural barrier to green bond market development in Sri Lanka has been the absence of a domestic green finance taxonomy. Without agreed definitions of what counts as a green investment or green asset, corporate issuers cannot credibly label their instruments as green, and investors cannot assess their claims.

CBSL Roadmap 2.0 directly addresses this. The development of a Sri Lanka green finance taxonomy is an explicit Roadmap commitment, and its completion is a prerequisite for the market’s next phase. The taxonomy will need to address the local context — Sri Lanka’s energy mix, the role of the plantation sector, the significance of coastal and marine ecosystems — rather than simply adopting a developed-market framework unchanged.

“Sri Lanka’s green bond market is not behind the curve — it is at the early part of the curve. The question is whether the structural conditions being built by CBSL will be matched by corporate issuers willing to bring credible instruments to market.”

When the taxonomy is in place, it will create the conditions for the first wave of credible corporate green bond issuances. Banks with labelled green loan portfolios will have a foundation for green bond funding. Energy companies with renewable projects will be able to issue project-specific instruments.

Who is positioned to issue

Among listed companies, the most credible potential green bond issuers are those with identifiable green asset pools that could serve as use-of-proceeds collateral. Windforce, as a renewable energy generator, has the most natural fit. Companies with significant solar investments in their property or hospitality portfolios, banks with established sustainability-linked loan books, and the National Development Bank — which has historically positioned itself at the green finance frontier — are the next tier.

A green bond requires more than a suitable asset pool. It requires a framework document, a second-party opinion from an accredited reviewer, ongoing reporting on use of proceeds and environmental impact, and investor relations capability to support a roadshow. These requirements are achievable for large corporates but represent a meaningful operational investment.

ESGNexus will track green bond and sustainability-linked bond issuances by Sri Lankan corporates. The first genuine domestic corporate green bond — credibly structured, taxonomy-aligned, and independently reviewed — will be a landmark for Sri Lanka’s capital market development.
