Green bonds are taking off—and could help save the planet
The "tragedy of the horizons," a term coined by Canada's Mark Carney, governor of the Bank of England, has been haunting the financial sector ever since climate change began posing serious threats to the planet.
As Carney put it: Can the financial sector address long-term climate change problems when most investments are made for the short term?
Behavioural economics has shown us that people lack the ability to think long term, and this has been the Achilles heel in our fight against climate change. However, there's now evidence that the "tragedy of the horizons" could be overcome due to changes in both our behaviour and our financial system.
Over the past few years, the idea of business-as-usual in the financial sector has been questioned by many. The wisdom so far has been to invest in what provides us with the lowest risk and has long-term stability.
Today, investors assess risk not just in terms of financial risk, but also social, environmental and governance (ESG) issues that may be critical to financial returns. Investors are demanding that investment firms start to factor in ESG components.
Green bonds changing financial sector
Green bonds, debt finance tools that have traditionally been used to raise long-term capital with low risk, may be answering the call for behavioural change in the financial sector.
Ever since the Industrial Revolution, bonds have played a critical role in financing infrastructure in cities and towns. A green bond transforms these infrastructure-related investments into low-carbon, climate change-resilient alternatives. Green bonds don't just have the capacity to address risk and stability in a way that considers the long-term impact of climate change —they can also change the way we think about money and returns as well.
With US$100 billion invested in green projects in 2017 alone, socially responsible investment products like green bonds have the potential to create massive change.
Green bonds not only provide similar financial returns as regular bonds, but also allow for a bonus "green" return from their investments. These bonus moral incentives could finally be starting to create a social and environmental conscience in the financial sector. Indeed, as more investors push for green bonds, climate change awareness continues to grow.
That means investors, and the financial sector as an extension, are starting to think long term about climate change. What's even more exciting is that the transformation to a low-carbon financial system is happening simultaneously around the world.
Several countries are issuing what are known as green economy road maps. Private sector green bonds are on the rise, and the process of divestment from fossil fuels has begun.
Impact on global financial system
There is now momentum for innovation in the financial sector, and it's changing how we think about our traditional investment portfolios, banking, credit and even fintech.
For a long time, socially responsible investing and its products were a niche market. However, with the advent of the green bond, this niche market is transitioning to the mainstream. According to the Climate Bonds Initiative, the market has surpassed the US$100 billion mark, with $116.8 billion being issued in 2017 alone. That's substantially more than the money that flows across global borders as official developmental aid for tackling climate change.
To really understand the magnitude of the impact of green bonds, let's look at the size of the market.
Currently, climate-aligned bonds are estimated to total US$895 billion, which is a $201 billion increase from the previous year. Out of that $895 billion, approximately $221 billion are labelled as green bonds. This growth is encouraging, but there's room for a much larger market given the increasing number of extreme weather events linked to climate change.
As those major floods and monster hurricanes continue, industries like the insurance sector will be less likely to take on clients or insure assets that do not meet climate change resilience standards. This is where having low-carbon, infrastructure-related investments from green bonds in a climate-resilient economy will make a big difference.
Interestingly, governments and public institutions account for almost 68 per cent of this amount, and developing countries such as China are currently leading the market. This exponential growth points to two things: Governments have a key role to play in the transitioning of this market, and perhaps this transition will be driven by emerging economies like China's.
The regulatory impact
So how much of an impact can government pressure have on the shift to a low-carbon economy? Looking at China as an example, our previous study at the University of Waterloo shows such pressure has indeed resulted in creating both financial and sustainability improvements in the credit businesses of Chinese banks.
Under the Chinese Green Credit Guideline Policy, banks reduced how much environmental risk they were exposing themselves to, especially when lending to their clients.
The guidelines forced banks to become financially and environmentally prudent in addressing climate change risks. The study found that there were improvements in both financial and sustainability performances, and the common linkage was the institutional impact of the Chinese public policy.
If such regulatory pressure can be replicated in the green bond market, it could bring about a low-carbon economy. Furthermore, green bonds could soon be subject to standardizations and certifications. With increasing fears of "green-washing" and concerns from investors about being misled by the green label, regulating the market would be beneficial —and could ensure green bonds continue to play an important role in fighting climate change.
