CAC 40 ESG : a good idea but a questionable approach ?
Decoding the launch of Euronext’s new ESG index
By Axel Camilleri

This past March, Euronext launched a new index in line with the European SFDR directives: the CAC 40 ESG. The index is made up of 40 French stocks holding highly valued environmental, social and governance practices. The companies are selected from the French CAC Large 60 benchmark.

The introduction of this new index is indeed in line with the times, as financial players are increasingly taking a sustainable approach to investments.

Transparency and result-oriented environmental-social-governance policies should be expected from this new ESG index.

Euronext gets advice for the constitution of the new index
Euronext manages 400 stock market indices, which represent the majority of total European benchmarks.
The index was launched in collaboration with V.E. (Vigeo Eiris), which is a subsidiary of Moody’s. V.E. is a global provider of environmental, social and governance solutions to investor and issuer communities.

V.E. appears to have guided Euronext in creating the ESG rating methodology of the CAC 40 ESG index, whereas Euronext will simply arbitrate and make the index available to investors.

More transparency needed
According to Euronext, the ethical principles of the CAC 40 ESG index are in line with the United Nations Global Compact Assessment and the French SRI label.

Little information is however available on Euronext’s website nor on its presentation leaflet, as per the Global Compact principles and the French SRI label.

The lack of information in this regard turns out to be surprising when considering one of the key principles of the SRI label is increased transparency for financial products.

Euronext still has the opportunity to provide more visibility on this front. The CAC 40 ESG index was created to promote transparency and highlight socially responsible investments for the large, listed companies in France.
Partial and few outright exclusions
Euronext has put into place principles of exclusion for the selection of CAC 40 ESG stocks. The three main exclusions are the following:
  • PProduction of weapons or weapon systems
  • PTobacco production
  • PCompanies facing heavy controversy under the UN Global Compact
Other sectors are additionally excluded depending upon revenue thresholds:
  • PCivilian arms production (over 5% of company revenue)
  • PTobacco distribution (more than 10% of company revenue)
  • PCompanies involved in coal mining, coal-fired power generation (more than 5% of company revenue)
The exclusions are, in other words, conditional and not outright straightforward: for example, with respect to the tobacco industry, distribution of the merchandise is tolerated (if it does not exceed 10% of the company’s revenue) but production of the product is not accepted.
We have difficulty understanding why the exclusions are not more clearly defined, which again, gives Euronext the opportunity to provide more clarity on its ESG rating methodology.
A selection methodology based on 38 ESG criteria
The ESG rating of the index (developed by V.E.) encompasses 38 ESG criteria, selected by Euronext.

V.E. therefore acts as ESG advisor and has no control over the selection of criteria for the composition of the score.

According to V.E., the ESG rating is equally weighted for each major pillar: E (Environment) represents 33.33% of the overall score, as well as for the S (Social) and G (Governance).

Two-hundred, fifty analysts at V.E. retrieve and process data from publicly listed companies, in accordance to the selected 38 criteria for the creation and updating of the index.

The data is sourced from:

  • PCompany websites
  • PCompany annual reports
  • PFactiva (Dow Jones database)
  • PBloomberg
  • PReuters
We know from the documents made available by Euronext that the criteria are approximately as follows:
Environment
Social
Governance
Environment
  • PEnvironmental protection
  • PSafeguarding the environment
  • PPrevention of environmental damage
  • PEstablishment of an appropriate management strategy
  • PEco-design
  • PProtection of biodiversity
  • PReasonable control of environmental impacts on the overall life cycle of products and services.
Social
Human rights
  • PRespect for trade unions
  • PFreedom and promotion of collective bargaining
  • PNon-discrimination and promotion of equality
  • PEradication of prohibited labour practices
  • PPrevention of inhuman or humiliating treatment
Human resources
  • PContinuous improvement of industrial relations
  • PCareer development
  • PQuality of working conditions
Community involvement
  • PContribution to the economic and social development of the territories where it is located and their human communities
  • PConcrete commitment to controlling the societal impacts of products and services
  • PTransparent and participatory contribution to public interest causes.
Business behaviour
  • PConsideration of clients' rights and interests
  • PIntegration of social and environmental standards both in the supplier selection process and in the overall supply chain
  • PEffective prevention of corruption
  • PCompliance with competition laws
Governance
  • PEfficiency and integrity
  • PEnsuring both the independence and effectiveness of the board
  • PEffectiveness and efficiency of audit and control systems
  • PInclusion of social responsibility risks
  • PRespect for the rights of shareholders and especially of minorities
  • PTransparency and moderation of executive remuneration
  • PEnvironmental protection
  • PSafeguarding the environment
  • PPrevention of environmental damage
  • PEstablishment of an appropriate management strategy
  • PEco-design
  • PProtection of biodiversity
  • PReasonable control of environmental impacts on the overall life cycle of products and services.
Human rights
  • PRespect for trade unions
  • PFreedom and promotion of collective bargaining
  • PNon-discrimination and promotion of equality
  • PEradication of prohibited labour practices
  • PPrevention of inhuman or humiliating treatment
Human resources
  • PContinuous improvement of industrial relations
  • PCareer development
  • PQuality of working conditions
Community involvement
  • PContribution to the economic and social development of the territories where it is located and their human communities
  • PConcrete commitment to controlling the societal impacts of products and services
  • PTransparent and participatory contribution to public interest causes.
Business behaviour
  • PConsideration of clients' rights and interests
  • PIntegration of social and environmental standards both in the supplier selection process and in the overall supply chain
  • PEffective prevention of corruption
  • PCompliance with competition laws
  • PEfficiency and integrity
  • PEnsuring both the independence and effectiveness of the board
  • PEffectiveness and efficiency of audit and control systems
  • PInclusion of social responsibility risks
  • PRespect for the rights of shareholders and especially of minorities
  • PTransparency and moderation of executive remuneration
It should be understood the criteria within each E-S-G pillar are also equally weighted. None hold more importance over others. For example, pillar E in the above table lists seven criteria each holding equal weightings (14,3% = 100% / 7 of the overall Environment score). A “waste generated per sales” metric is equal in severity to a “green building policy” metric? Are flashing red warning lights detecting a potential oil spill in the energy sector equal in severity to picnic littering?

On a positive note, the criteria are adapted according to the sector of activity. For example, a question regarding eco-design will be directed to a company in the consumer sector, but not necessarily to a company in the pharmaceutical sector.

How is the grade calculated?
Each company is given an overall score out of 100 (the higher the better), which is a weighted and consolidated score of all sustainability factors in a given sector.

The ESG evaluations are only made on a relative basis, in which each assessment of a criterion is scored from 1 to 4.

Selection of companies in the CAC 40 ESG benchmark
V.E. and Euronext created the CAC 40 ESG index by beginning with the CAC Large 60 index as a starting point, applied the exclusions and filters of the 38 ESG criteria, and subsequently selected the CAC 40 ESG stocks.

The analysis is repeated on a quarterly basis in order to arbitrate which companies enter or exit the ESG index.

Lack of ambition on behalf of Euronext
The choice of exclusions by Euronext is commendable and legitimate: arms production, tobacco and companies in controversy with the United Nations.

While barring those companies in conflict with the UN Global Compact is most sensible, little detail is given as to how companies are assessed with respect to human rights, labour laws, child exploitation, etc.

Again, why not define “exclusions” more clearly?

The launching of the CAC 40 ESG index supports transparency in the corporate world, yet the Euronext website hardly shares any information on this front.

Euronext chose to use only 38 criteria to establish the ESG rating of the new index. In comparison to the hundreds of ESG-related criteria used in the evaluation processes of other rating agencies (Bloomberg, Sustainalytics, Robecco etc.), Euronext’s more limited criteria appear meagre.

Criteria overall are not regularly updated by companies, but over the long run, more and more questions will most likely need to be answered, ideally leading to frequent information snap-shots on a broad spectrum of data.

Colibri Asset Management uses 78 criteria for the ESG rating of its allocations, and we expect to use more than 200 over the medium term.

From an informational qualitative viewpoint, data analysis in both relative and absolute terms deem to be an optimal methodology. Absolute data of greenhouse gas emissions (in thousands of tonnes), as an example, can be a valuable indicator to measure the carbon footprint of a company.

V.E.’s current approach of scoring an indicator, from 1 to 4, only gives a relative estimate of a company’s ESG practices versus more precise, pertinent, absolute data.

V.E. informed us their methodology targets the ESG rating of financial products and benchmarks with equally weighted E, S, G pillars and criteria. While we know the Euronext ESG rating process belongs to V.E., we can additionally conclude the process is prudently conservative and far from earth shattering. Little incentive apparently exists to budge the current established “eco-system”.

When reading through Euronext’s brochure, it can be seen the highest ESG rating in the CAC 40 ESG index is 75. While high ESG ratings should translate into richer valuations of companies, less upside potential could put a drag on the index overall. Instead of focussing on best-in-class stocks, wouldn’t investors gain more value if E-S-G trajectories were at the centre of Euronext’s evaluation process?

In the table to the left we see the difference in ESG ratings between the CAC Large 60 (written in black) and the CAC 40 ESG (in green). The Average column variation in Overall Scores is strikingly small (63 versus 59) and questions the raison d’être of the CAC 40 ESG index.

This implies the CAC Large 60 companies could almost match the CAC 40 ESG companies in terms of stock price performance. What is therefore the point of creating the new CAC 40 ESG index if CAC Large 60 companies barely differ in ESG ratings?

V.E. states the variation in Overall Scores is negligible because the incremental reduction in focussed companies from 60 to 40 is not a significant change in absolute terms. The explanation may at first appear valid, but wouldn’t heavily polluting companies, such as Total in the CAC Large 60, pull down the Overall Score to much lower levels?

The table to the left meanwhile displays noticeable differences in rating methodologies between Colibri Asset Management and Euronext. While we have the impression Euronext tends to over-rate companies in terms of ESG ratings (Total example above), the different E-S-G pillar weightings at Colibri Asset Management also steer us towards different conclusions:

  • Environment: 50%
  • Social: 30 %
  • Governance: 20 %
The 78 Colibri Asset Management ESG criteria also hold varying weights within each pillar to better measure the varying incremental impacts to the environment, as well as social and governance practices. For example, the “Percentage of disabled employees in the workforce” metric holds a 9% weighting in the Social pillar versus the 3% metric weighting for “Lost incident time rate per employee”.

Our final differentiating factor blends absolute numbers (e.g. CO2 emissions in thousands of tonnes per year) with relative data (e.g. “yes” or “no” answers) to create the E-S-G trajectories of companies. The historic evolution perspective therefore permits Colibri Asset Management and its clients to better evaluate the current trends for investment idea generation.

Conclusion

The initiative launched by Euronext is commendable and meets the requirements of new European standards.

However, the apparent lack of ambition in this fine project caps the needed change we need in the world today.

Selecting best-in-class for the CAC 40 ESG benchmark proposes investors high quality companies, yet the flip side points to little leeway in making improvements and hence, generate decent investment returns.

If this project is carried out in the spirit of exposing reality to French large caps, (i.e. not living up to consumer demands), we could witness a game changing evolution.

The environment after all needs to gain more recognition by means of appropriate social and governance practices.
