Investing in climate action through green bonds

How investors can support sustainability and earn in the process.

Green bonds are carving out a growing niche in the Philippine financial market, giving investors a way to support environmental projects while earning steady returns.

Instead of sitting idle in savings accounts, funds from green bonds are channeled to initiatives such as solar farms, flood control systems, and renewable energy infrastructure—projects that contribute directly to sustainability targets while offering competitive yields.

What are green bonds?

Green bonds function like conventional bonds but are earmarked exclusively for projects with measurable environmental benefits. The issuer, whether a government agency, development bank, or corporation, raises funds from investors and commits to using the proceeds only for climate-related undertakings.

Investors earn fixed interest over a specified period, similar to traditional bonds. The difference lies in the impact. That’s because every peso invested contributes to projects that mitigate climate risks or reduce carbon emissions.

Market adoption and accessibility

The Philippines has been ramping up its green finance ecosystem in recent years. In 2024, the Bureau of the Treasury issued the country’s first-ever retail green bonds, raising billions of pesos from both institutional and individual investors. The proceeds were earmarked for climate-resilient infrastructure and renewable energy projects.

Access has also become more inclusive. Retail investors can now participate through banks and digital platforms. Major players such as BDO Unibank periodically open green bond listings during offer periods, while GCash users can invest in “GBonds” via the GInvest feature starting at P500.

The growing ease of participation signals a democratization of climate investing, turning what was once a niche, institutional product into a viable option for everyday Filipinos seeking stable, purpose-driven returns.

Accountability and impact

Green bonds are governed by international frameworks such as the International Capital Market Association’s (ICMA) Green Bond Principles, which require issuers to disclose project details, impact metrics, and post-issuance reports.

Aside from having to disclose the specific project the funds were used for, such as clean transportation or renewable energy, entities must also report concrete metrics that track their success. Investors can expect, for example, to know how many tons of carbon dioxide were reduced or how much green power was generated.

These transparency standards boost investor confidence and ensure that funds are genuinely directed toward environmental outcomes, whether measured in megawatts of renewable energy generated or tons of carbon emissions avoided.

As sustainability becomes a key metric for both profitability and corporate responsibility, green bonds represent a growing intersection of finance and climate action. 

Through green bonds, investors can turn their savings into direct support for projects driving the country’s green transition.
