What if your savings could both grow and finance the ecological transition? Are you wondering how to combine financial performance with personal convictions without getting lost in the jungle of so-called "green" investments? How can you navigate the world of sustainable investing in the stock market, distinguish real opportunities from mere marketing operations, and make informed decisions for your wealth and for the planet?
This guide is designed to accompany you step by step. We will decode together the mechanisms of green finance, explore the best options to invest responsibly in 2024, and give you the keys to build a portfolio that makes sense.
Understanding Green Investing: Beyond Appearances
Green investing, often grouped under the broader banner of Socially Responsible Investing (SRI), consists in directing your capital toward companies, funds, or projects that actively contribute to the ecological transition. The objective is twofold: to generate a positive and tangible environmental impact while aiming for a financial return on your savings. Far from being a mere trend, this approach responds to a global awareness and the necessity to redirect financial flows toward a more sustainable economy.
To structure this approach, investors and fund managers rely on the ESG criteria (Environmental, Social, and Governance). These criteria evaluate a company not only on its financial results but also on its ecological impact (waste management, CO2 emissions, water consumption), social policy (gender equality, working conditions, training), and governance quality (transparency, fight against corruption, business ethics).
Two main strategies coexist in the world of responsible investing. The first is the exclusion approach, which consists of excluding from one’s portfolio companies active in sectors considered harmful, such as fossil fuels, weapons, or tobacco. The second, more nuanced, is the "best-in-class" approach. It consists of selecting, within each sector (including the most polluting ones), the companies that demonstrate the most significant efforts to improve their practices and commit to the energy transition. A "best-in-class" fund could, for example, invest in an oil company that is massively pivoting toward renewable energies.
The Different Ways to Invest Responsibly in the Stock Market
Investing in ecology in the stock market is not limited to buying shares in a wind turbine company. A whole ecosystem of products and solutions has developed to enable you to invest your money according to your risk profile, objectives, and desired level of involvement.
Funds and ETFs: The Gateway to Diversification
For those starting out or who do not wish to analyze companies one by one, investment funds and ETFs (Exchange Traded Funds), also called "trackers," are an ideal solution. These financial products group dozens or even hundreds of different stocks or bonds within a single investment. They offer instant diversification, allowing risk sharing.
- Green funds are actively managed by experts who select companies based on an investment thesis focused on the environment: renewable energies, energy efficiency, water management, circular economy, etc.
- Ecological ETFs are funds that passively replicate the performance of a stock index composed of companies meeting strict ESG criteria. Their management fees are generally much lower than those of active funds.
Here are some examples of ETFs focused on responsible themes, illustrating the variety of options available:
| Management Company | ETF Name | Thematic | Annual Fees |
|---|
| Amundi | Green Bond ETF | Global bonds financing green projects (Greenfin Label) | 0.25% |
| Amundi | Gender Equality | Global stocks of companies leading in gender equality | 0.20% |
| iShares | MSCI EM SRI | Stocks of socially responsible companies in emerging countries | 0.25% |
| iShares | MSCI Japan SRI | Stocks of socially responsible companies in Japan | 0.20% |
| Amundi | MSCI USA SRI | Stocks of socially responsible companies in the United States | 0.18% |
Tax Wrappers to Optimize Your Green Investments
In France, you can hold these funds and ETFs within advantageous tax wrappers to optimize the net performance of your investments.
Life insurance is the most flexible wrapper. By choosing a unit-linked policy, you can access a wide range of funds labeled SRI or Greenfin. Increasingly, players such as Goodvest or Nalo offer fully-managed portfolios focused entirely on sustainable investment, aligned with the Paris Agreements.
The Retirement Savings Plan (PER) is a solution dedicated to preparing for your future. Like life insurance, it allows investing in green funds while offering an interesting tax advantage: the payments you make can be deducted from your taxable income. Specialized SRI PERs, such as those offered by Placement-direct or Goodvest, facilitate this approach.
Finally, the Equity Savings Plan (PEA) allows investing in European stocks with very attractive taxation after 5 years of holding (capital gains tax exemption, excluding social charges). Although its universe is limited to Europe, there are SRI ETFs eligible for the PEA that allow building a responsible portfolio.
Expert Advice
For an optimal green investment strategy, do not hesitate to combine wrappers. Use a PEA for your investments in responsible European stocks to benefit from its favorable taxation. Complement it with life insurance or a securities account to access international funds and ETFs (American, emerging markets) and thus geographically diversify your portfolio.
Green Bonds: Financing Concrete Projects
A green bond is a loan issued by a company, local authority, or state solely to finance projects with a clearly identified environmental benefit. By buying a green bond, you know your money will be earmarked for building a solar park, developing clean transport infrastructures, or implementing highly energy-efficient buildings.
The uniqueness of these instruments lies in their transparency. Specialized rating agencies verify that the raised funds are indeed allocated to the announced projects and measure the real environmental impact. It is a very direct way to ensure your capital concretely contributes to the transition.
Crowdfunding and Private Equity: A More Direct Impact
For investors seeking greater involvement and to finance the real economy in a targeted way, crowdfunding is an increasingly popular option. Specialized platforms like Enerfip, Lendosphere, or Miimosa allow you to lend money or take equity in SMEs and startups developing concrete projects: biogas plants, agroecology farms, local solar installations, etc. You choose the projects that match your values.
At another level, private equity offers the possibility to invest in unlisted companies, often with high growth potential, that are at the heart of innovation for decarbonization. While the entry ticket is higher and the investment less liquid (locked up for several years), the potential for performance and impact is considerable. Fund-of-funds, such as AxClimat I by Anaxago, allow diversification across several private equity funds specialized in the energy transition.
Knowing How to Decode Investments: Beware of Greenwashing
The success of green finance has unfortunately attracted its share of abuses. Greenwashing is a marketing practice whereby a company or fund gives itself a misleading image of ecological responsibility without truly backing it up with concrete actions. It is therefore crucial to learn to look under the hood.
Labels: Useful Guides but Not Infallible
To help savers navigate, official labels have been created. In France, the two most important are:
- The SRI label: Created by the Ministry of Finance, it guarantees that the fund applies a rigorous ESG methodology, often based on the "best-in-class" approach. It does not focus solely on the environment.
- The Greenfin label: Created by the Ministry of Ecological Transition, it is much stricter on the environmental aspect. It completely excludes companies in the fossil fuel and nuclear sectors and guarantees that a majority of the fund is invested in "green" activities defined by a precise list (renewable energies, sustainable buildings, etc.).
Beware of the Mirage of Labels
A label is a good starting point but should not replace your own analysis. Greenwashing can hide in the details. Some SRI-labeled funds may still contain companies with controversial activities because the "best-in-class" methodology allows it. Always take the time to consult the detailed fund composition to ensure it matches your values.
How to Analyze an Investment Beyond the Label?
To become a savvy green investor, you need to develop certain reflexes. Do not be content with the fund’s name; delve into its documentation. Look at the top 10 companies in which it invests. These often represent a significant portion of the portfolio. A simple search on these companies will teach you a lot about their real activities.
For a more thorough analysis of a company’s carbon impact, it is useful to understand the notion of emission scopes:
- Scope 1: The company’s direct emissions (e.g., factories of a car manufacturer).
- Scope 2: Indirect emissions related to the energy it consumes (e.g., electricity to run its factories).
- Scope 3: All other indirect emissions, upstream (suppliers) and downstream (use of its products).
Consider the example of a manufacturer of internal combustion engine cars. They may have very modern factories powered by renewable energy and thus show an excellent balance on scopes 1 and 2. However, scope 3, which includes the emissions of all the cars it sells during their lifetime, will be colossal. A genuine green fund must analyze all three scopes to assess a company’s overall impact.
Beyond the Stock Market: Carbon Allowances, a Direct Lever of Impact
Investing in green stocks or funds means financing companies committed in the right direction. But there is another, more direct and less known approach to act on the climate: investing in carbon allowances.
The carbon allowance market (or "pollution permits") is a mechanism created by public authorities, notably the European Union (EU ETS), to force the most polluting industries to reduce their emissions. Each year, a limited number of allowances is allocated. If a company pollutes more than the allowances it holds, it must buy more on the market. If it pollutes less, it can sell them. The price of allowances is directly linked to the decarbonization effort: the faster the transition, the lower the demand for allowances and their price; the slower the transition, the higher the price, encouraging companies to invest to reduce their emissions.
It is precisely this virtuous mechanism that we make accessible at Homaio. Our approach is simple: we enable individual investors to buy carbon allowances. By doing so, you remove these permits from the market. They can no longer be used by industries to pollute. The supply of allowances decreases, which, at constant demand, makes their price rise and strengthens the incentive to decarbonize. This is a direct, measurable, and quantifiable impact. You are not just financing a promise of transition; you actively contribute to making pollution more expensive. This financial asset thus combines performance, since the price of carbon is expected to increase to meet climate objectives, and a real ecological impact.
2024 Trends and Outlook for Sustainable Investing
Green investing is no longer a niche; it is a fundamental trend that is shaping all finance. In 2024, several dynamics are confirmed. Regulations, such as the European SFDR directive (Sustainable Finance Disclosure Regulation), push managers to be more transparent about the sustainability of their products, thereby limiting greenwashing.
We also observe a growing specialization of investments. Beyond generalist ESG funds, more precise themes are emerging and gaining popularity: circular economy, biodiversity preservation, carbon capture technologies, and green hydrogen. This granularity allows investors to refine their strategy and target the areas closest to their hearts. The demand from savers, increasingly aware of the climate emergency, continues to grow, encouraging management companies to innovate and offer ever more relevant and impactful solutions.
Taking the step toward green investing today is more than a financial choice; it is a civic act. It is deciding that your wealth should work not only for you but also for a more sustainable future. The options are numerous, from diversified ETFs to targeted crowdfunding projects, to innovative mechanisms like carbon allowances. The key is to stay curious, stay informed, and build a portfolio that reflects not only your financial goals but also your core values. By becoming an engaged investor, you actively participate in the greatest transition of our time.
Frequently Asked Questions About Green Investing in the Stock Market
Why invest in green finance?
Investing in green finance allows you to align your financial objectives with your ethical and environmental values. The ecological transition requires massive investments. By directing your savings toward sustainable companies and projects, you actively participate in this transition while positioning your wealth in future-oriented sectors. It is a way to become an actor of change while growing your capital.
Are green investments less profitable?
This is a persistent misconception increasingly contradicted by facts. Many studies show that, in the long term, companies with good ESG practices are often more resilient, better managed, and less exposed to regulatory or reputational risks. They can therefore show financial performance equal to or even superior to that of the traditional market. However, as with any investment, performance is never guaranteed and depends on the chosen products.
What is the difference between an SRI-labeled fund and a Greenfin-labeled fund?
The difference is major. The SRI label is generalist: it ensures that the fund integrates ESG criteria in its management, often by selecting the "best" companies in each sector ("best-in-class"), including polluting sectors. The Greenfin label is a purely ecological label, much stricter. It formally excludes fossil fuel and nuclear sectors and guarantees that most of the portfolio is invested in activities directly contributing to the ecological transition. For maximum environmental impact, the Greenfin label is the most demanding.
How can I start investing green with a small budget?
It is perfectly possible to start with modest amounts. Several options are available to you:
- Scheduled payments: Many life insurance or PEA contracts allow setting up automatic transfers of just a few dozen euros per month toward an ETF or green fund.
- Neo-brokers: Platforms like Trade Republic allow buying fractions of stocks or ETFs for just a few euros.
- Crowdfunding: Some crowdfunding platforms allow investing in green projects starting at €20 or €50.
The important thing is not the initial amount but regularity and a long-term vision.
