The stock market is evolving, and with it, our expectations of companies. The CAC 40 ESG was born from this awareness. It’s not just another list of stocks, but a selection of French companies that are making a particular effort to be more responsible. We look not only at their profits, but also at their impact on the environment and society. It’s a way of showing that money can also be used to build a better future, by choosing companies that share these values.

Understanding the CAC 40 ESG: A Responsible Approach
Definition and Origin of the CAC 40 ESG
The CAC 40 ESG, launched in March 2021, represents a natural evolution of the financial market, responding to growing demand for more sustainable investments. It is essentially a version of the traditional CAC 40 that incorporates Environmental, Social, and Governance (ESG) criteria into its selection of companies. The idea behind its creation is simple: to highlight large French companies that not only perform financially but also actively engage in responsible practices. Faced with a collective awareness of climate and social issues, the financial world had to offer indices that reflect these new expectations. The CAC 40 ESG is that response, offering an investment framework that seeks to reconcile economic performance with positive impact.
Objectives Behind the Index’s Creation
The main objective of the CAC 40 ESG is to offer an alternative for investors who wish to align their investments with their values. It aims to identify and value companies that demonstrate a strong commitment to sustainable development. This translates into a rigorous selection based on ESG indicators, going beyond simple market capitalisation. The index also seeks to encourage companies to improve their social and environmental responsibility practices, thereby creating a virtuous cycle. By highlighting these companies, the CAC 40 ESG hopes to stimulate green innovation and ecological transition within the French economic fabric.
Euronext’s Role in Index Management
Euronext, as the leading European stock exchange, plays a central role in the management and promotion of the CAC 40 ESG. It was Euronext that designed and launched this index, thus marking its commitment to sustainable finance. The company is responsible for the selection methodology, data publication, and regular review of the index’s composition. By managing major benchmark indices like the CAC 40, Euronext lends its credibility and infrastructure to ensure the reliability and transparency of the CAC 40 ESG. Its role is to ensure that the index remains true to its objectives and continues to reflect best ESG practices among large French companies, while facilitating market access to these investments. The stock exchange plays a key role in promoting gender equality within the CAC 40, and the CAC 40 ESG is part of this ongoing effort to improve corporate practices.
The CAC 40 ESG Selection Methodology
Environmental, Social, and Governance (ESG) Criteria
The CAC 40 ESG does not select its companies at random. It relies on a rigorous approach that assesses companies based on Environmental, Social, and Governance (ESG) criteria. These criteria have become increasingly important for investors who wish to align their investments with their values. The rating agency V.E, a subsidiary of Moody’s, is responsible for this assessment. It examines around forty key points for each company. These points cover aspects such as environmental impact (waste management, energy transition), social relations (working conditions, diversity), and how the company is managed (transparency, anti-corruption).
The Exclusion Process for Controversial Companies
Beyond the positive assessment of good practices, the CAC 40 ESG also applies strict exclusions. Certain activities are simply incompatible with the idea of responsible investment. This includes companies whose core business is related to tobacco, thermal coal, or controversial armaments. This exclusion policy ensures that the index only includes companies that are actively committed to sustainable development. It is a way of guaranteeing investors that their money supports activities that are more respectful of the planet and society. Companies are assessed on a quarterly basis, meaning their inclusion in the index can change if their practices evolve.
The Role of the Rating Agency V.E
The agency V.E plays a central role in the construction of the CAC 40 ESG. It conducts in-depth analyses of candidate companies. Its work involves assessing each company’s ESG performance according to a well-defined methodology. It uses a combination of public data and information provided by the companies themselves. The results of these assessments determine which companies meet the index’s requirements. This external expertise brings essential credibility and objectivity to the selection process. Without this independent assessment, it would be difficult to guarantee the relevance and reliability of the ESG criteria applied. Companies wishing to be included in the CAC 40 ESG must therefore demonstrate solid and transparent practices in terms of corporate social responsibility.
Fundamental Differences Between the CAC 40 and the CAC 40 ESG
The classic CAC 40 and the CAC 40 ESG share a common base, but their selection philosophies differ significantly. While the traditional CAC 40 primarily focuses on market capitalisation and stock liquidity to determine its components, the CAC 40 ESG goes further by integrating an essential qualitative dimension: Environmental, Social, and Governance (ESG) criteria. This approach guarantees investors that the included companies adhere to higher standards of sustainability and responsibility.
Market Capitalisation vs. ESG Criteria
The most striking difference lies in the selection process. The CAC 40 is a market index that includes the 40 largest French market capitalisations. Its composition is therefore dictated by the size and ease of trading of the stocks. In contrast, the CAC 40 ESG, while considering company size, imposes a rigorous selection based on their ESG performance. This means that even a large company can be excluded if its practices do not meet established environmental, social, or governance standards. This qualitative approach ensures that the index reflects not only economic power but also companies’ commitment to a more sustainable future.
The Impact of Sectoral and Normative Exclusions
The selection process for the CAC 40 ESG involves specific exclusions that do not exist in the main index. Certain activities are deemed incompatible with responsible investment. For example, companies whose core business is related to fossil fuels, controversial armaments, or tobacco may be excluded, even if they are among the largest capitalisations. This exclusion policy helps to build a portfolio that avoids risks associated with social or environmental scandals and is better aligned with current societal expectations. Companies are assessed on around forty ESG criteria by specialised agencies, such as V.E.
The ‘Best-in-Class’ Selection Applied to the CAC 40 ESG
The CAC 40 ESG adopts a ‘best-in-class’ approach. Rather than simply excluding the least performing companies on an ESG basis, it aims to select the best among large French capitalisations. Companies are ranked according to their ESG performance, and only those that reach a certain threshold are included in the index. This method ensures that the index is composed of leaders in sustainable development within the French economy. The index composition is also reviewed quarterly by Euronext, allowing for continuous adaptation to changes in company practices.

Performance and Investment Prospects of the CAC 40 ESG
Comparison of Short- and Long-Term Performance
When we look at the figures, the CAC 40 ESG and the classic CAC 40 show quite similar short-term trajectories. This is quite logical, given that many companies are part of both indices. But if we take a step back, over the medium and long term, differences begin to emerge. And often, it’s the ESG index that comes out on top. Companies that are better prepared for environmental and social challenges, those with better governance, seem to hold up better during market turbulence. They are less exposed to regulatory risks, fines, or unpleasant surprises that can cause a stock to plummet. Moreover, the CAC 40 index showed strong performance in 2025, exceeding 10%, suggesting positive prospects for financial investments, although the evolution for 2026 requires further analysis.
The Increased Resilience of ESG Companies
We observe that companies integrating ESG criteria into their strategy tend to be more robust. They better anticipate changes, whether at the regulatory level or in consumer expectations. For example, a company that invests in the energy transition or ensures good working conditions for its employees can avoid costly crises. It’s a bit like having insurance: it might cost a bit more upfront, but it prevents major problems later on. Diversity within teams, for instance, is often linked to better performance, as it brings varied perspectives and improved decision-making. Professional equality within CAC 40 companies is also linked to increased performance.
Future Growth Drivers for the CAC 40 ESG
The future looks quite promising for the CAC 40 ESG. Several trends are working in its favour. Firstly, regulations around sustainable development are strengthening. Things like the European taxonomy or the CSRD directive require companies to be more transparent and virtuous. Secondly, investors, especially younger ones, are increasingly demanding investments that have meaning and are responsible. And then there are all the sectors related to the ecological transition: clean electricity, sustainable mobility, hydrogen, recycling… These are areas that are bound to develop and are well represented in the CAC 40 ESG. Investing in this index therefore means betting on companies that are already future-oriented and are benefiting from these new growth dynamics. It’s a way to seek performance while aligning with values that are important to many of us.
How to Invest in the CAC 40 ESG?
Are you wondering how to invest your money in companies that care about the environment and social aspects? That’s an excellent question, and fortunately, there are quite simple ways to achieve this. The idea is to follow the CAC 40 ESG index, which brings together the best-performing French companies on these criteria.
ETFs as the Preferred Investment Vehicle
The most direct and often the most practical way to invest in the CAC 40 ESG is through an ETF, or Exchange Traded Fund. Think of it as a basket of stocks that faithfully replicates the index’s composition. When you buy a share of a CAC 40 ESG ETF, you are effectively investing in all the companies that make it up, in proportion to their weight in the index. It’s a way to easily diversify your money. The first ETF replicating this index was launched in September 2021, and since then, others have followed, making this investment increasingly accessible. It’s an approach that allows you to benefit from the growth potential of large French companies while supporting those committed to more responsible practices. For those looking to align their investments with their values, it’s a serious avenue to explore.
Eligibility for the Plan d’Épargne en Actions (PEA)
Good news for French savers: investments in the CAC 40 ESG, particularly through ETFs that track it, are often eligible for the Plan d’Épargne en Actions (PEA). This means you can potentially benefit from favourable taxation on capital gains and dividends, provided you comply with the PEA rules, especially the holding period. This is a significant advantage that makes investing in responsible companies even more attractive. It’s always a good idea to check the specific eligibility of each product with your advisor or bank, but generally speaking, the PEA offers an interesting framework for this type of sustainable investment. CAC 40 ESG companies are selected according to strict criteria, and their inclusion in the PEA allows for a combination of financial performance and positive impact.
Understanding Associated Fees and Risks
Like any stock market investment, investing in the CAC 40 ESG involves fees and risks. ETFs generally have quite low annual management fees, which is an advantage compared to some actively managed funds. However, there are always costs to consider, even if they are minimal. Regarding risks, it’s important to know that even though CAC 40 ESG companies are selected for their resilience and good practices, they remain subject to general stock market fluctuations. The index’s performance can therefore vary. Furthermore, the index composition is reviewed quarterly, meaning companies can enter or leave the index depending on the evolution of their ESG performance. It is important to stay informed about the practices of the companies that make up your investment. Companies that are subject to particular attention during written question campaigns at general meetings, for example, may see their position in the index change [4394]. Therefore, it is important to keep an eye on these developments to make informed decisions.
The Companies Comprising the CAC 40 ESG
Quarterly Review of the Index Composition
The list of companies included in the CAC 40 ESG is not set in stone. It is reviewed and adjusted every quarter. Euronext’s scientific committee is responsible for this. They look not only at how companies are performing financially but also, and this is the core issue, at how they manage their environmental, social, and governance (ESG) aspects. If a company has made progress or, conversely, has regressed on these points, its place in the index may be called into question. It’s a bit like a regular technical inspection to ensure everyone stays on the right track.
Examples of Included and Excluded Companies
When the CAC 40 ESG was launched, we saw that some well-known companies from the classic CAC 40 were not included. For example, TotalEnergies was not selected, mainly due to the environmental impact related to its core business, fossil fuels. Similarly, Thales was excluded due to its involvement in armaments. These decisions show that ESG criteria are taken seriously and can lead to exclusions, even for large companies.
Conversely, other companies, sometimes from the CAC Next 20, have been included in the index. These include EDF, Arkema, Valeo, and Bureau Veritas. Their inclusion is explained by their ability to demonstrate good ESG policy practices. They have shown that they take environmental, social, and governance issues into account in their strategy.
The Importance of ESG Practices for Index Membership
In essence, to be part of the CAC 40 ESG, it’s not enough to be a large company. You have to prove that you act responsibly. Companies are assessed on around forty criteria. This ranges from carbon footprint and waste management for the environmental aspect, to working conditions, diversity, and social dialogue for the social side. For governance, we look at transparency, the independence of boards of directors, and the fight against corruption. There is also an exclusion system that automatically sets aside activities deemed problematic, such as tobacco, coal, or controversial armaments. Membership in the CAC 40 ESG is therefore a direct reflection of a company’s ESG practices. This guarantees investors that they are investing their money in companies aligned with current sustainability expectations and, potentially, with their own values.
The CAC 40 ESG: A Responsible Alternative for Investors
In conclusion, the CAC 40 ESG represents a logical evolution of the traditional CAC 40, responding to growing demand for investments that are more respectful of the environment and society. By incorporating Environmental, Social, and Governance (ESG) criteria, it offers a selection of companies that not only perform financially but also commit to sustainable practices. Although its methodology is more demanding, excluding certain controversial activities, it has shown an ability to perform comparably, or even better, than the classic CAC 40, particularly during turbulent periods. For investors whose ethical convictions are important, or who seek to diversify their investments while anticipating future regulations, the CAC 40 ESG represents a serious and relevant option. It allows for aligning financial objectives with personal values, while benefiting from the growth potential of large French companies.
