What are Green Bonds?

Green bonds are any type of bond instruments where the proceeds will be exclusively applied to finance or re-finance eligible green projects. They provide capital for new and existing projects with environmental benefits, like renewable energy, energy efficiency, pollution prevention, sustainable water, and wetlands or marine resource management.


The Rapid Growth of the Market

This growth has been driven by both increased demand from institutional investors looking to allocate capital to sustainable projects and the need for large-scale investments to address climate change and transition to a low-carbon economy.
The growth is expected to continue strongly in the coming years with many analysts projecting the size of the green bond market could surpass $1 trillion per year by 2025. New issuers are regularly entering the market across both developed and emerging economies. Countries and cities are also increasingly tapping the market to fund climate action plans through large sovereign and municipal bond issuances.

Use of Proceeds and Project Evaluation

They are differentiated from regular  Green Bonds by transparency on the use of proceeds and environmental impact reporting. The key steps in a typical green bond include:

- Defining eligibility criteria for projects (renewable energy, energy efficiency, etc.) aligned with market standards like the Green Bond Principles.

- Identification and evaluation of eligible green projects by the issuer that deliver clear environmental benefits.

- Tracking procedures to ensure bond proceeds are allocated to financing eligible projects.

- Regular reporting on the projects funded and estimates of energy savings, emissions reductions or other environmental impacts achieved.

This provides assurance to investors that their capital is being directed specifically to activities with environmental benefits. Third-party reviews are also sometimes used to confirm alignment with eligibility criteria.

Standards and Certification

Several voluntary frameworks and standards have emerged to support transparency and integrity in the market:

- The bond principles are a set of guidelines issued by the International Capital Market Association (ICMA) that most issuers voluntarily follow when bringing a to market.

- The Climate Bonds Standard provides a climate science-based certification scheme for green bonds. Certified Climate Bonds must meet eligibility criteria that ensure consistency with objectives of the Paris Climate Agreement.

- The EU Taxonomy is a classification system establishing criteria for environmentally sustainable economic activities. It will require specific disclosure for green bond issuances aligned with EU Taxonomy criteria.

- Credit ratings agencies like S&P and Moody’s have created green bond assessments to score an issuer’s environmental credibility.

These standards help differentiate truly from bonds with merely a 'green label' while also increasing demand from investors seeking robust standards.

Financing the Energy Transition

Arguably the most pressing task for the market is financing the global transition to renewable energy and low-carbon power systems. According to the IEA, annual clean energy investment worldwide needs to increase to $4 trillion by 2030 to put the world on track to reach net-zero emissions by 2050.

They have shown they can make a meaningful contribution by financing utility-scale solar and wind projects, battery storage, grid upgrades, "smart grid" technologies, green hydrogen production and renewable natural gas. Corporate issuers in the energy sector have also used it to fund sustainable initiatives.

Outside the power sector, they are financing climate resilience projects like flood defenses, supporting low-carbon transportation through infrastructure for electric vehicles and mass transit, building retrofits to increase energy efficiency, and new technologies to abate industrial emissions. With energy representing the largest share of global emissions, they dedicated to renewable power deployment will play a key role in achieving climate goals.

Long-Term Investor Demand

They are resonating with institutional investors as a way to align portfolios with environmental objectives while still earning stable returns. Pension funds, insurance companies, asset managers and sovereign wealth funds have become repeat issuers and large buyers of green bonds due to factors such as:

- Tangible environmental impact of the projects financed, addressing issues like climate change that pose long-term risks to assets and liabilities.

- Additionality of financing green projects that may otherwise struggle to attract capital in early stages.

- Diversification from traditional fixed income products as the fast-growing market expands opportunities.

- Responding to beneficiaries demanding sustainable options from their investments.

With many major investors committed to achieving net-zero portfolios, they offer a way to satisfy broader sustainability mandates while earning core fixed income yields and credit spreads. As long as its issuance routes capital clearly towards low-carbon development, this investor class is likely to sustain long-term demand.

they have established themselves as a scalable private sector mechanism for financing critical environmental projects and directing investment towards transitioning the world economy to a more sustainable path. With continued growth and alignment with emerging policy initiatives like the Paris Agreement, this bond segment is poised to play an increasingly strategic role in the collective effort to accelerate climate action.
