This thesis examines whether ESG still “pays” financially for European firms between 2015 and 2025, in a context shaped by the EU’s Green Deal and CSRD on the one hand and by overlapping crises, inflation, and tighter financing conditions on the other. Methodologically, it conducts a systematic literature review with a qualitative (narrative) synthesis of quantitative, firm‑level studies on the ESG–CFP relationship for European companies. The final evidence base comprises 23 studies.
Financially, ESG effects are more consistent in market‑based and risk‑related outcomes (e.g., valuation multiples, volatility/risk measures, and in some studies the cost of capital) than in short‑term accounting profitability (ROA/ROE), where results are smaller and more heterogeneous. Across ESG dimensions, the social pillar emerges as the most robust driver of firm value; environmental effects appear more context-dependent (often stronger in high‑impact sectors through transition‑risk channels), while governance mainly functions as an enabling condition for credible ESG strategies. Over the 2015–2025 window, the review does not identify a strong, consistent time trend in the ESG–CFP relationship. A key reason is that relatively few studies isolate crisis subperiods cleanly enough to compare pre‑crisis, crisis, and recovery phases in a consistent way.

Objectives & Themes
This thesis investigates whether Environmental, Social, and Governance (ESG) performance remains financially beneficial or at least not harmful for European firms between 2015 and 2025. The core problem addressed is the limited synthesized evidence on how the ESG-Corporate Financial Performance (CFP) relationship specifically manifests in Europe within this period, and whether it shows stability, weakening, strengthening, or qualitative change compared to global baselines, amidst Europe's evolving regulatory and macroeconomic conditions.
- Analysis of the relationship between ESG performance and Corporate Financial Performance (CFP) for European firms.
- Examination of the impact of Europe's "polycrisis" (including COVID-19, energy shock) and tightening sustainable-finance regulation.
- Application of a systematic literature review (SLR) methodology following PRISMA principles.
- Investigation into different financial outcomes: profitability, market valuation, risk, and cost of capital.
- Delving into the mechanisms through which ESG affects financial performance, with a focus on value creation, risk management, and compliance costs.
Excerpt from the Book
1.2 Problem statement
As outlined in the previous section, existing meta-analyses and large-scale reviews broadly suggest that ESG performance is, on average, not detrimental and often positively related to corporate financial performance (CFP). Across the major syntheses, roughly two thirds of underlying studies report a positive ESG–CFP association, most of the remaining findings are neutral and clearly negative results form only a small minority (Friede et al. 2015, p. 224; Whelan et al. 2021, pp. 4–7). Overall, the estimated effects are typically small to moderate in magnitude: ESG tends to be associated with slightly higher profitability and valuation multiples and with a lower cost of capital and downside risk, rather than with large systematic outperformance (Atz et al. 2023, p. 26; Hornuf and Yüksel 2024). Taken together, this evidence provides a cautiously optimistic baseline: ESG has rarely been shown to reduce financial value and has often been associated with modest improvements in returns and risk profiles.
However, these conclusions are derived largely from global pooled samples that mix regions, sectors and time periods. Most underlying primary studies were conducted before or at the very beginning of the changes in the operating environment over the past decade, and only a subset explicitly focuses on European firms. Existing meta-analyses therefore offer, at best, a global average; they do not reveal how strongly the ESG-CFP relationship holds specifically for Europe, nor whether it has changed under the conditions that have characterized the period since around 2015 (Huang 2021, pp. 335-360; Narula et al. 2025, pp. 10–14).
The European context has been transformed along several dimensions. The EU has tightened the regulatory and reporting framework around sustainability, which embeds long-term climate objectives into corporate reporting and financial regulation (European Commission 2018; European Union 2022). At the same time, Europe has been exposed to polycrisis, with interacting shocks undermining previous economic and political equilibria (Lawrence et al. 2024, pp. 4-6). The war-related energy shock and cost-of-living crisis have put severe pressure on margins and investment budgets, while political debates and a visible softening of ESG rhetoric among leading asset managers have introduced additional uncertainty about how strongly markets will reward or punish ESG behavior (European Central Bank 2022; McGowan 2024).
In this altered environment, it is no longer straightforward to assume that the globally observed pattern of ESG being neutral to mildly positive for financial performance applies to European firms without qualification. On the one hand, tighter regulation and heightened transition and physical risks could increase the financial relevance of ESG-related capabilities by making resilience, resource efficiency, and credible transition planning more valuable. On the other hand, higher compliance and adjustment costs, combined with intense competitive pressure in crisis conditions, could compress margins and weaken or neutralize any financial advantage of strong ESG performance in the short to medium term (Narula et al. 2025, pp. 10-16). From a management and investor perspective, the question is therefore not only whether ESG “pays off” in principle, but also whether the direction and strength of the ESG-CFP relationship in Europe have shifted over the past decade.
Existing reviews rarely isolate European firm-level samples and seldom differentiate between pre- and post-polycrisis periods in a way that is directly useful for European decision-makers. As a consequence, decision-makers are left without a consolidated, context-specific picture of whether the widely cited global ESG-performance relationship still holds under post-2015 European conditions, or whether it has weakened, strengthened, or qualitatively shifted.
The core problem addressed in this thesis can therefore be formulated as follows: Despite a large global literature, there is limited synthesized evidence on how the ESG-CFP relationship manifests specifically for European firms in the period 2015–2025, and whether the post-2015 European evidence suggests stability, weakening, strengthening, or qualitative change compared to the widely cited global baseline.

Frequently Asked Questions
What is this work fundamentally about?
This work fundamentally investigates the relationship between Environmental, Social, and Governance (ESG) performance and corporate financial performance (CFP) for European firms during the period of 2015–2025, specifically examining if ESG initiatives are financially beneficial in a turbulent European context.
What are the central thematic areas?
The central thematic areas include the impact of ESG performance on various financial outcomes, the influence of EU sustainable finance regulation and the "polycrisis" environment, and the differing effects across market-based versus accounting-based metrics, as well as individual ESG pillars (Environmental, Social, Governance).
What is the primary objective or research question?
The primary objective is to synthesize evidence on how the ESG-CFP relationship manifests for European firms between 2015 and 2025, assessing whether this relationship has remained stable or undergone shifts compared to global baselines, and interpreting these patterns in the European context.
What scientific method is used?
The scientific method employed is a systematic literature review (SLR) with a qualitative synthesis of quantitative, firm-level evidence, following PRISMA principles and applying predefined inclusion criteria.
What is covered in the main part?
The main part covers the theoretical and empirical background of the ESG-CFP relationship, the detailed methodology of the systematic review, the empirical results derived from the analyzed studies, and a discussion of these findings in the context of the European macroeconomic and regulatory environment, leading to practical implications.
Which keywords characterize the work?
Key terms characterizing this work are ESG, Financial Performance, Europe, Polycrisis, Systematic Review, Firm-Level Evidence, Sustainability, EU Regulation, Green Deal, Corporate Financial Performance (CFP), Risk Management, Resilience, Cost of Capital, Market Valuation, and Social Pillar.
How does the "polycrisis" in Europe influence the ESG-CFP relationship?
The European "polycrisis" (including COVID-19, energy shocks, and political polarization) does not devalue ESG financially but shifts its role from generating systematic outperformance to primarily contributing to risk management and resilience, offering downside protection against adverse events and regulatory surprises.
Which ESG pillar (Environmental, Social, Governance) shows the strongest financial impact in Europe?
Across the studies, the social pillar (S) consistently emerges as the most robust positive driver of firm value, often showing stronger links to market valuations and overall sustainability outcomes than the environmental (E) or governance (G) pillars, which tend to be more context-dependent or mixed in their effects.
What are the practical implications of these findings for European managers?
For European managers, the thesis suggests that ESG is not a "free lunch"; true financial upside appears when ESG is implemented substantively, focusing on human and social capital, and investments that reduce transition and scandal risk, rather than mere disclosure or box-ticking.
Are ESG effects more consistent in market-based or accounting-based financial outcomes?
ESG effects are more consistently positive and reliable in market-based financial outcomes such as Tobin's Q, market-to-book ratios, volatility, and cost of capital, whereas their impact on accounting-based profitability measures like ROA and ROE is smaller, more heterogeneous, and sometimes even negative in the short term.
