Private equity (PE) represents one of the most influential, dynamic, and secretive forces in modern finance, an engine of capitalism characterized by aggressive value creation initiatives, operational transformations, and high return expectations. Traditionally focused on financial performance above all else, PE has evolved into a powerful force reshaping industries through active ownership approaches and long-term strategic control. As the landscape shifts in response to changing societal expectations and global challenges, new questions arise about how PE can continue to outperform – and whether this outperformance should evolve beyond the income statement.
PE Investors are increasingly focusing on sustainable verticals, not only for the general good of the planet, but because these verticals offer attractive growth prospects. Contemporary research highlights the increased importance of sustainability as a value driver, as firms seek to balance profitability with ESG. The notion that ESG is viewed as a cost centre for risk mitigation is challenged by perspectives that sustainability can be a strategic value and profit driver, enhancing value creation in PE at every stage of the investment process. Despite only 20% of General Partners (GPs) embedding ESG professionals in investment teams, such constellations tend to outperform. Findings support sustainable PE investing as a driver of investor engagement, new value creation sources and differentiated investment strategies.
Rethinking Private Equity: Can Sustainability Drive Alpha in Europe?
Private equity (PE) firms across Europe are increasingly investing in sustainable industries – but does going green pay off? A recent study from Copenhagen Business School explores this timely question, examining whether exposure to sustainable verticals improves fundraising outcomes, value creation strategies, and ultimately, return on investment (alpha) in European PE.
Using a mixed-methods approach, the authors combine fund-level data from 207 European PE funds with eleven semi-structured interviews from leading PE investment firms like Novo Holdings, FSN Capital, Vitruvian Partners and Nordic Alpha Partners. Findings provide conditional support: Sustainable investments, when backed by institutionalized capabilities, can enhance PE fund performance in terms of fundraising, value creation and returns.
Sustainability Signals Attract LP Capital If Backed by Substance
Sustainable investment strategies increasingly serve as a fundraising differentiator. Limited Partners (LPs) are allocating capital to GPs who can credibly demonstrate alignment with environmental goals. However, signaling alone isn’t enough. LPs now expect PE funds to show internal ESG capabilities and clear integration into decision-making processes. As the thesis puts it, “sustainability is no longer a nice-to-have but a core differentiator”, if it can be backed up by institutionalized resources and capabilities.
Specialization Matters – Especially in Sustainable Verticals
Funds that specialize in sustainable verticals such as energy transition, green infrastructure, or sustainable agriculture, tend to outperform generalist counterparts when it comes to active value creation. Why? Because specialization reduces information asymmetries during both the deal-sourcing and ownership phases, enabling a better understanding of the asset. These funds build up domain-specific expertise and operational toolkits that generalist funds often lack.
Sustainability Can Boost Returns, But May Also Increase Risk
The thesis finds a statistically significant 3.97 percentage point increase in IRR for funds with high exposure to sustainable verticals. However, this return premium comes with increased volatility. While sustainability exposure seems to enhance IRR, it does not show the same effect on cash-on-cash metrics like TVPI. This suggests that the financial impact of sustainable investing may depend on how you measure it, and how well it is executed.

Challenges and Trade-Offs
Investing in sustainable verticals does not come without challenges. These industries often have fragmented value chains, regulatory uncertainty, and Capex-intensive business models. The research underscores that generating strong returns requires deep sector knowledge, operational engagement, and credible ESG resources and capabilities.
Moreover, the current funding gap in Greentech presents a structural risk. Despite ambitious climate goals, growth-stage funding for Greentech remains insufficient. The authors suggest that new partnership models such as blended finance and public-private co-investment are necessary to bridge this “valley of death” and unlock the full potential of sustainability in PE growth investing.
Implications for PE 4.0
The thesis frames this evolution as part of “PE 4.0” – new era where value creation mechanisms expand beyond traditional financial engineering to include ESG integration, operational transformation, and long-term risk mitigation. In this model, sustainability is not a constraint, but a strategic lever.
Final Thoughts
The study provides a comprehensive empirical contribution to sustainable investing in European PE. It challenges the outdated dichotomy between “doing good” and “doing well,” showing that, under the right conditions, PE firms can achieve both simultaneously. The findings raise a crucial question for practitioners: Is your strategy future-fit, or falling behind?
