Common Mistakes New Environmental Investors Make
Environmental investing is attracting increasing attention as the transition to a lower-carbon economy creates opportunities across renewable energy, storage, environmental technologies, carbon markets, biodiversity and the circular economy.
For investors entering the sector for the first time, however, enthusiasm needs to be matched by discipline. Environmental investing is still investing. An asset does not become a good investment simply because it has a positive environmental story.
Here are some of the most common mistakes new environmental investors make.
1. Thinking Environmental Investing Is Just Like ESG Investing
ESG investing and environmental investing can overlap, but they are not the same approach.
ESG investing generally considers environmental, social and governance factors when assessing investments. An ESG strategy may therefore invest across a broad range of industries, using these factors as part of its investment selection or risk assessment process (1).
Environmental investing is more directly focused on the environmental opportunity itself. It seeks exposure to assets, businesses and technologies that contribute to environmental outcomes, including renewable energy, battery storage, resource efficiency, recycling, carbon abatement and innovative environmental technologies.
That distinction is important for new investors.
An ESG portfolio may help investors consider environmental risks within a conventional investment portfolio. Environmental investing can go further by deliberately allocating capital to the assets and solutions required for the environmental transition, which in our view, leads to excess returns.
2. Believing Everything Labelled "Green" Is Green
Environmental terminology has become increasingly valuable in marketing, which also creates the risk of greenwashing.
ASIC defines greenwashing as misrepresenting the extent to which a financial product or investment strategy is environmentally friendly, sustainable or ethical (2). ASIC has specifically highlighted the importance of products being "true to label" and of clearly explaining sustainability-related terminology and investment screening criteria.
New investors should look beyond words such as "green", "clean", "sustainable" and "net zero".
What does the investment actually own? How are environmental outcomes assessed? Are there measurable criteria? Are there exclusions or revenue thresholds? Does the environmental claim reflect the underlying business?
Australia's Sustainable Finance Taxonomy is another step towards creating common definitions for sustainable economic activities and reducing the potential for greenwashing (3).
The environmental credentials need to survive scrutiny.
3. Forgetting That Financial Returns Still Count
Wanting to generate a positive environmental outcome does not remove the need to assess an investment commercially.
A technology may be impressive but have no viable path to profitability. A renewable energy project may have attractive long-term characteristics but be purchased at an excessive valuation. A company may have enormous potential but continually require additional capital.
Environmental investors should still consider revenue, cash flow, debt, management, valuation, competitive advantage, capital requirements and the potential return relative to the risks being taken.
The objective is not simply to identify good environmental ideas. It is to identify good investments within the environmental opportunity.
4. Chasing the Latest Environmental Theme
Investment markets love a story.
Hydrogen, lithium, batteries, carbon credits, electric vehicles and other environmental themes have all experienced periods of intense investor attention.
That does not mean investors should avoid emerging themes. It means they should avoid investing purely because something is fashionable.
Moneysmart warns that investing because something is trending on social media or in the news can be risky and recommends understanding how an investment makes money, how it works and the risks involved before committing capital (4).
The environmental transition is likely to extend across decades. Investors do not need to chase every new opportunity that appears.
5. Putting Everything into One Environmental Theme or Asset
Environmental investing is not one asset class.
Renewable infrastructure can behave differently from an early-stage environmental technology company. Green debt has different characteristics from carbon markets. Battery storage has different risks from biodiversity-related assets.
Concentrating an environmental portfolio in one company, technology or theme can leave investors exposed to regulatory changes, technological disruption, commodity prices or project-specific risks.
Diversification remains one of the basic principles of investing. Moneysmart recommends spreading investments across and within asset classes to reduce portfolio risk (5).
Environmental investing should be approached with the same discipline.
6. Ignoring Liquidity
This can be particularly important in environmental investing.
Some of the most interesting environmental opportunities are not listed on a stock exchange. Renewable infrastructure projects, private environmental businesses, project finance and emerging technologies may be difficult for individual investors to access directly.
Unlisted investments can also be less liquid. Investors may not be able to sell an investment immediately simply because they want their money back.
That makes liquidity, investment horizon and portfolio construction important considerations. An attractive long-term environmental asset may still be unsuitable for someone requiring short-term access to their capital.
7. Assuming Direct Investing Is Always Better
Buying a few listed renewable energy or clean technology shares can provide environmental exposure, but it may not provide the diversification investors expect.
Some environmental opportunities are private. Others require specialist assessment, substantial minimum investment amounts or access to deal flow that individual investors may not possess.
This is one reason professionally managed environmental funds can play a role.
The EnviroInvest Investment Fund, for example, seeks to provide wholesale investors with diversified exposure to environmentally conscious assets across multiple investment types. Rather than requiring investors to identify, assess and access individual opportunities themselves, the Fund provides a single investment vehicle through which qualifying investors can gain broader environmental exposure.
8. Waiting for the "Perfect" Environmental Investment
Perhaps the final mistake is never getting started.
No investment will be perfect. Technologies change, regulation evolves and different environmental assets will carry different financial and environmental risks.
The transition towards a more sustainable economy will require enormous amounts of investor capital. Investors therefore have an opportunity to think not only about the financial future they are building for themselves and future generations, but also about the economy and environment those future generations will inherit.
Environmental investing provides an opportunity for capital to do both.
The Bottom Line
New environmental investors do not need to abandon traditional investment principles. They need to apply them.
Understand what you own. Look beyond the label. Assess the environmental credentials. Consider valuation and financial fundamentals. Diversify. Understand liquidity. Be conscious of risk.
Most importantly, recognise that environmental investing is not simply about finding investments that make investors feel good.
It is about finding investments capable of generating a financial return while directing capital towards the environmental transition already reshaping the Australian and global economy.
For investors who believe that transition will continue, the bigger mistake may ultimately be having no exposure at all.
