The EU’s Regulatory Framework on Sustainability in Financial Investments: From Disclosure to Taxonomy
The EU’s regulatory requirements for sustainability in financial investments have now been completed with the Taxonomy Regulation following the Disclosure Regulation. After more than 40,000 comments were received during the consultation phase, the most enlightening insights are found not so much in the legal text itself, but in the 60 recitals that precede the Regulation and explain its rationale.
With rare candor, one can read in Recitals 9–11 that the European Parliament and the Council, through Regulations (EU) 2019/2088 and (EU) 2020/852, are not aiming solely at sustainability. They also intend, almost incidentally, to reshape the European financial system. The financial industry is being instrumentalized as a means to an end: to steer and control capital flows within the Union. For instance, it is stated that “the financial system should be gradually adapted […]” so that it “supports the economy in a way that allows it to function sustainably.” To achieve this, a new form of finance must become “the standard.”
Naturally, the financial industry lends itself quite well to being exploited for political purposes. Since Member States have delegated conceptual regulatory tasks to the EU, the Union can now use regulations like those mentioned above to define the room for maneuver for financial market participants in such a way that they are almost compelled to act in the centralized interest of EU institutions—thereby undermining the subsidiarity principle and the economic policy competencies of individual Member States.
The European treaties, like the EU Constitution itself, were written in the spirit of a principal-agent relationship between the governments of the Member States and the EU institutions. That’s why (also in economic policy) the ultimate directive authority has always remained with the sovereign states.
This limitation of power is a thorn in the side of many EU bureaucrats. It’s therefore not surprising that in recent years there have been increasing Machiavellian efforts to shift directive authority and decision-making power from the Member States to the European institutions.
When delegated supervisory powers are misused to exert influence on Member States’ economic policy—under the guise of ecological sustainability—this constitutes nothing less than a breach of the EU constitution.
Once one works through the Taxonomy Regulation to the actual legal text, it becomes apparent that the EU has largely abandoned the ESG triad of Environmental, Social, and Governance objectives. The Regulation focuses almost exclusively on environmental sustainability goals. Yet even here, no guidance is provided on how sustainability should be measured or evaluated. Instead, the Regulation contains numerous diplomatic compromises. For example, Article 19(2) allows the inclusion of nuclear energy’s carbon-free status, or—somewhat humorously—declares that “[…] a significant increase in the generation, incineration or disposal of waste constitutes environmental harm – with the exception of incinerating non-recyclable hazardous waste.”
However, the urgently needed standardization of ESG evaluation criteria remains elusive. Article 19 of the Taxonomy could even be interpreted to mean that at least quantitative assessments of sustainability impact must rely solely on indicators, methods, models, or certifications recognized by the European Union.
The obligations for financial market participants and advisors are primarily qualitative in nature and mostly aimed at consumer protection. A central requirement is disclosure and justification—why a product is classified as sustainable, what objectives it pursues, and how these are to be achieved. To meet these regulatory requirements, the financial industry will likely have to rely even more heavily on purchased data and ESG ratings in the future.
Yet it is well known that ESG ratings from different providers vary significantly. Various studies on this topic have reached very similar conclusions. As representative evidence, the bottom left image shows a scatter plot from Fiduciary Advisors comparing ESG ratings from MSCI and Sustainalytics for S&P 500 companies. The coefficient of determination is just 0.29—visibly low—yet consistent with findings from other analyses.
Evidently, the sustainability assessment of an individual company depends heavily on which data is used. In light of the regulatory requirement to demonstrate overall sustainability impacts for financial products—by comparing them to a sustainable benchmark index and a broader market index—it is even more problematic that such rating discrepancies persist across entire portfolios.
In our own analysis (top right of the image), we evaluated ESG risk for indices in the MSCI Europe family using data from both providers. The correlation was virtually non-existent. When broken down by sector (not shown here), a growing ESG focus by MSCI even led to lower ESG risk scores in one-third of industries—when assessed with Sustainalytics data.
In other words, even when regulatory requirements are implemented consistently by all parties, the same product can be evaluated and advised on in entirely different ways by different financial actors. The regulations’ intended goals—investor education and product transparency—are thus rendered meaningless.
The Taxonomy answers only some of the questions raised by the preceding Disclosure Regulation. It allows broad room for interpretation and thus introduces legal uncertainty. It also risks confusing potential clients more than it helps them. For disclosure of ecological assessment criteria to be genuinely valuable to investors—and to enable sufficient comparability of financial products’ sustainability impacts—a standardized evaluation process is essential. A first step in the right direction could be mandatory ESG audits of companies. The resulting standardization of a binding set of data would likely lead to greater convergence in the ratings provided by agencies.
Until then, developing one’s own evaluation method might be worth considering. We have had positive experiences with a methodology that relies exclusively on publicly available data sources and yields surprisingly strong results, particularly in the often-neglected “S” and “G” categories. Details of this method are beyond the scope of this brief. But if you’re interested, feel free to reach out to us.
Let’s end with some good news: For financial firms feeling squeezed by the triple burden of COVID, regulation, and climate change, the Taxonomy offers a way out—complete with a pre-formulated disclaimer. Just copy and paste it onto your website if needed:
“The investments underlying this financial product do not take into account the EU criteria for environmentally sustainable economic activities.”
