Clean and green investing for a low-carbon economy

Key Takeaways

  • Transforming the global economy to be less dependent on fossil fuels requires more use of renewable energy sources.
  • Investors may find opportunities in the innovations and the funding of projects to reduce carbon emissions.
  • ETFs can help investors target shares of renewable energy-related stocks to provide the potential for long-term growth and green bonds to directly fund environmental projects.

Extreme weather events are calling attention to the costs of climate change and creating urgency around transforming the global economy — a monumental undertaking that could triple annual investment in clean energy by the end of this decade.1

This summer has seen forest fires first sweep across the Western U.S. and Canada, then Southern Europe, while floods inundated parts of Northern Europe and Central China. Recent ecological shocks follow a record year for weather-related damages in 2020.2

The scientific consensus is that the global economy needs to quickly become less carbon-intensive to avoid continued extreme and catastrophic impacts.3 Transitioning away from fossil fuels, which now account for about 80% of the total energy supply, will require major investments in new technologies, infrastructure, and projects designed to reduce the threat.4 By one estimate, meeting current carbon-reduction targets could require installing the equivalent of the world’s current largest solar park every day for the rest of this decade.5

Given the magnitude of the changes we foresee, long-term investors may find opportunities in the technologies and innovations that create renewable energy sources or reduce the carbon intensity of energy production.

The role of renewable energy in reaching net zero

To help spur the economic transformation, governments and companies are pledging commitments to become “net zero.” Net zero is about reducing greenhouse gas emissions so that over time we can achieve an overall balance between emissions produced, and the emissions removed from the overall atmosphere. So, for every ton of greenhouse gas emitted into the air, a ton needs to be taken out. More than 125 governments around the world and more than 1,000 companies have made or are preparing to make net zero commitments. We expect that number to go up.

Attaining net zero will require huge investments, changes in business models, and innovation. Major energy producers say that oil production likely peaked in 2019, and the race is on for cheap, clean ways to produce electricity.6 To reach net zero emissions by midcentury, annual clean energy investment will need to more than triple by 2030 to around $4 trillion.7

Both stocks and bonds will be important to financing the transition to a sustainable, low-carbon economy, and exchange traded funds (ETFs) are a convenient way to target companies and issuers at the forefront of driving the transformation of the energy systems that underpin the global economy.

Accessing renewable energy in the stock market

We believe more and increasingly restrictive climate-related policies and growing consumer preferences are likely to spark breakthroughs in renewable energy, which should have knock-on effects that enable scaled production and widespread adoption.

Despite the investment potential for renewable energy, conventional stock benchmarks do not capture renewable energy in a meaningful way. For example, the S&P 500 Index — a common benchmark that represents the U.S. stock market — includes just 0.6% direct exposure to clean energy companies.8

For broader access to renewable energy, investors may want to look instead to stock indexes that straddle conventional classifications, including size, and region, to better reflect the realities of renewable energy innovation.

What projects are green bonds funding?

Considering green bonds

Bond markets are playing a key role in helping fund environmental projects through the issuance of green bonds.

Green bonds are issued by governments, government agencies, and companies. What makes them unique is that proceeds are exclusively applied toward new and existing green or environmental projects. Such projects include climate adaption, sustainable water, or pollution prevention and control. Investing in green bonds allows investors to fund projects meant to deliver a measurable environmental impact in their fixed income portfolio.

The green bond marketplace has grown markedly since the World Bank issued the first of its kind in 2008.9 Despite uncertain market conditions in 2020, green bond issuance hit a record $270 billion and last year the total size of the global marketplace eclipsed $1 trillion.10

Summing it up

BlackRock believes we are in the beginning stages of a transition to a low-carbon economy that is creating historic opportunities and risks that are not currently captured in financial markets.

Investors looking to capitalize on long-term growth opportunities may want to consider introducing clean energy stocks and green bonds to pursue both financial and environmental outcomes into their portfolios. ETFs offer affordable, convenient and diversified access to securities related to renewable energy.
