ESG investing refers to investment strategies that incorporate Environmental, Social and/or Governance factors into the decision-making process. The ESG investment market has experienced significant growth over the last years, becoming a central and global investment strategy and asset class. According to Morningstar, global ESG fund assets reached $3.4 trillion by September 2024 (considering exchange-traded assets), with Europe leading the market and accounting for nearly three-quarters of total assets. Global ESG fund assets show a general upward trend over the period, accelerating through 2023 and 2024.

Despite periods of market volatility, there is an overall upward trend on ESG fund assets, driven by a combination of regulatory pressure, investor demand, climate-related risks, and emerging investment opportunities. Projections by Bloomberg estimate that global ESG assets could surpass $40 trillion by 2030², representing more than 25% of global assets under management.

The alternative investments’ space has also seen a large increase in ESG-focused investment over the years. Fundraising for ESG-focused funds in alternative assets has nearly doubled from 2018 to 2023 from c.$45BN to c. $90BN³. Like in the exchange-traded space, Europe leads the market, representing two thirds of total fundraising in 2023. This growth is likely to persist in the future, increasing the relevant importance of ESG investments in the context of alternative assets.

As ESG investing continues to grow, one of the biggest challenges is defining what qualifies as truly sustainable and ensuring transparency in financial products. The EU is leading the way globally in promoting sustainable finance. It plans to reduce CO₂ emissions by 55% in 2030 compared to 1990 levels. To address this, the EU has established a regulatory framework that links the EU Taxonomy with the Sustainable Finance Disclosure Regulation (SFDR). These regulations work together to define and regulate ESG investments, ensuring that investors receive clear and reliable information.

The EU Taxonomy is the official classification system that determines which economic activities can be considered environmentally sustainable.  It is based on six environmental objectives: Climate change mitigation, climate change adaptation, sustainable use and protection of water resources, transition to a circular economy, pollution prevention and control, and protection of biodiversity and ecosystems. To qualify, an investment must substantially contribute to one of the six objectives, not significantly harm any of the others, and meet minimum social and governance safeguards. Additionally, the activity must comply with the Technical Screening Criteria (TSC), a set of detailed, sector-specific thresholds established by the European Commission. The EU Taxonomy acts as a technical guide, ensuring that sustainability claims are based on clear scientific and economic criteria.

The SFDR complements the EU Taxonomy by creating a framework for financial institutions to disclose how sustainability is integrated into their investment processes and products. It applies both at the entity level and at the product level.

At the entity level, all financial market participants must publish their sustainability risk policy, explaining how environmental and social risks could affect investment returns. Additionally, they are also required to disclose a remuneration policy that outlines how sustainability factors influence investment decisions, and to produce a Principal Adverse Impact (PAI) statement that describes how their investments might negatively impact environmental or social objectives.

At the product level, the SFDR introduces a clear classification system that helps investors understand the level of ESG commitment within each financial product. Products are categorized into three groups based on their sustainability ambition. The first group consists of SDFR Article 6 funds, which integrate ESG risks and considerations into their decision-making process but have no specific ESG focus. The other two groups, SDFR Article 8 and Article 9 funds, both have an ESG orientation, with Article 8 funds simply promoting positive environmental or social characteristics but not having sustainability as a core objective, and Article 9 funds that have sustainability as their primary objective.

As the ESG market grows, the risk of greenwashing increases. Greenwashing refers to the practice of artificially marketing financial products as sustainable without them really having an orientation towards sustainability. The EU’s regulatory framework, particularly the SFDR and the EU Taxonomy, is designed to tackle this risk by requiring clear, measurable and standardized disclosures from financial products and institutions.

Beyond SFDR, there are voluntary initiatives like the Principles for Responsible Investment (PRI), a set of voluntary guidelines created by the United Nations that plays an important role in promoting responsible investment. By signing the PRI, asset managers commit to integrating ESG factors into their investment decisions and being transparent with their clients. While the PRI is not legally binding, it adds an additional layer of accountability and aligns investment practices with global sustainability goals.

Additionally, another alternative that fund managers can use to achieve ESG alignment is to link performance incentives, like carried interest, to specific ESG targets such as carbon reduction, diversity improvements or alignment with the EU Taxonomy. This approach ensures sustainability is embedded in the investment strategy and that the firm’s team is appropriately incentivized to drive performance improvement across the chosen ESG metrics.

The growing focus on sustainability is creating a wide range of investment opportunities in private equity across multiple sectors and strategies, from early-stage funds to more traditional buyout investments. We see an increasing number of funds operating in the impact investing space, where capital is directed toward businesses that generate measurable social or environmental benefits alongside financial returns. Meanwhile, traditional buyout funds are also integrating ESG factors into their investment process, identifying opportunities where improving environmental or social performance can enhance long-term value.

We can conclude that the ESG investment market is growing significantly and is becoming a significant portion of overall investments, particularly across European alternative assets. Regulations like the EU Taxonomy and SFDR are driving transparency in the sector and helping to set the benchmark for responsible investments in Europe, and managers are increasingly aligning with these standards, while also aligning compensation incentives to ESG performance.
