According to the OECD, an estimated US$6.9 trillion per year of climate-aligned infrastructure spending is required to meet the Paris Agreement’s goals of keeping global temperatures from exceeding 1.5°C – 2.0°C above pre-industrial levels.

We have seen government entities and corporations increasingly turning to green bonds to raise the capital required to invest in decarbonisation or renewable energy projects. This is why green bonds play a fundamental role in climate action – they have the potential to radically accelerate our journey towards net zero.

However, in order for green bonds to help achieve a truly positive impact on the environment, we need to build a better, more transparent green bond market.

The Growing Green Bond Market

The issuance of green bonds grew over the last decade, and in the last few years, we have seen a substantial acceleration. According to Climate Bonds Market Intelligence, the green bond market reached a record US$517.4bn at the end of 2021, representing the highest total since market inception.

While green bond issuance hasn't yet exceeded 2021's record, we did see a record set in 2023 for green bond sales from corporates and governments, which climbed to US$575bn. So, it’s a safe assumption that the trend for a growing green bond market will continue.

Greenwashing Accusations

However, this rapid growth has also brought into question the quality of certain bonds, signalling a potential problem of market confidence – some issuers are being accused of greenwashing. One concern is that some issuers may be taking advantage of strong investor demand to fund activities that do not truly have a positive environmental impact, hence misdirecting market capital that was intended to make a positive difference.

There now exists a growing demand from both the public and private sectors for the transparency, granularity and verifiability of data that underlie green bonds, as these fixed-income instruments are only meaningful if there is evidence that positive climate action has been created.

Essentially, green bonds must stand up to scrutiny or buyers won’t invest in them. Equally, potential issuers may steer clear of the instrument for fear of greenwashing accusations.

Building a Better Green Bond Market with Technology

In order to build a robust, credible green bond market, there are areas for optimisation and improvement where technology could play a critical role.

1. A blockchain-based system for data collection

One area of optimisation is in the method of data collection for substantiation of environmental performance. Historically, the monitoring of use of proceeds, underlying asset performance and environmental impact have been done through periodic manual processes, resulting in a lack of timely data, material time and cost incurred and the potential for human error.

These challenges can be addressed through the implementation of a blockchain-based system supported by smart devices and other digital processes. By collecting data at the asset level and recording or referencing it on-chain, stakeholders will have a verifiable, auditable data feed on a near real-time basis.

This implementation shows asset performance and environmental impact down to the individual investor level. Such a framework can support numerous finance-related activities concurrently, whether it be for reporting, accounting, or ratings – all at a fraction of the time and cost of manual processes.

2. Tokenized green bonds

However, to issue a truly optimised green bond, this digital-driven data collection should be coupled with a digitised blockchain-based financial product, or “tokenized” bond.

These tokenized bonds can be permanently linked to an underlying data set, ensuring the tokenized bond, its use of proceeds and environmental impact can be easily monitored and verified at any time.

Issuing a tokenized green bond tied to a verifiable data feed not only shows that an organisation is truly committed to its sustainability goals, it will also manage the risk of eventual mandatory regulations and provide a level of transparency that mitigates any risk of greenwashing.

While not yet mainstream in the monitoring of green bond compliance, we expect that real time and digital monitoring of use of proceeds, underlying asset performance and environmental impact will become a new standard in the green finance space within the next 2 to 3 years. With technology-enhanced green bonds, there is an increasingly high degree of confidence that capital being deployed is actually going to assets or projects that are positive for the planet. This in turn will increase confidence in the market, spurring further investment into green projects on the timeline needed to fight climate change.
