Sustainable Investment in 2025: Key Trends and Strategies for Asset Owners to Maximize Impact

1. Transitioning to a Low-Carbon Economy

Aligning investments with decarbonization goals remains a popular trend. Many Asset Owners are setting ambitious targets through frameworks like the Task Force on Climate-related Financial Disclosures (TCFD) and Science Based Targets initiative (SBTi). Membership in the Net Zero Asset Owner Alliance continues to grow, with new commitments to shorter-term climate milestones.

The investment product landscape has expanded to support the global climate transition. Firms like BlackRock, BNP Paribas, and HSBC have all recently launched funds focused on energy transition infrastructure. In the UK, specialized Long-Term Asset Funds targeting the energy transition have gained traction, with two new infrastructure funds introduced in 2024. Additionally, transition bonds are experiencing strong demand, exemplified by Climate Investment Funds’ heavily oversubscribed investment-grade bond issued on the London Stock Exchange.

2. Place-Based Impact Investments

Place-based Impact Investing (PBII) aligns financial returns with ESG outcomes, emphasizing local or regional projects like improved housing, clean-energy infrastructure, and SME business growth. These strategies are particularly relevant in the UK, where Local Government Pension Schemes (LGPS) and Defined Contribution (DC) pensions face government driven consolidation to push significant investment into local infrastructure and businesses. Collaborations between pension pools and regional authorities have directed capital into place-based projects to meet allocation obligations.

Asset Managers are also providing tailored solutions, such as L&G’s 2024 Affordable Housing Fund, developed with LGPS-Access. Beyond geographic focus, specialized impact funds enable broader social goals through both public and private market investments. As global central banks continue to cut interest rates in-line with falling inflation, we expect to see an increase in high-quality “green” infrastructure investment opportunities.

3. Nature-Based Investments

Nature-based investments are an emerging frontier, focusing on outcomes around biodiversity, rewilding, and ecosystem restoration while generating financial returns. Asset Managers are combining investment and scientific expertise in areas like carbon capture, agriculture, and forestry. The growing interest in “Natural Capital” funds is reflected in the onset of specialist strategies from firms such as Nuveen, alongside the substantial funding raised by private equity and venture capital firms in 2024.

Improved data and resources support the growth of nature-based investments. For instance, the UN Principles for Responsible Investment launched its biodiversity guide for Asset Owners in 2024, providing a framework for integrating biodiversity considerations into the investment process.

1. Operating Model

To expand sustainable allocations, Asset Owners must align their business strategy with investment goals through an effective operating model. Outsourcing to specialist third-party managers offers operational efficiency and expertise; but requires robust oversight and well-defined investment frameworks. For major allocations, such as private markets impact investments, Asset Owners may also invest into in-house portfolio management expertise.

While building internal capabilities may reduce costs over time and enhance alignment between sustainable strategies and execution, it demands significant investment in specialized personnel, technology, and data architecture – bringing far more complexity which may not suit traditional Asset Owners.

• The challenge: Asset Owners must carefully evaluate their operational needs, balancing the benefits of outsourcing with the potential advantages of in-house capabilities. They should also establish strong governance structures to ensure alignment with their sustainable investment goals and execution of their chosen model. Establishing current state limitations and defining the most optimal model with stakeholder buy-in, is a common challenge for Asset Owners.

2. Data and Oversight

With growing availability of data and transparency around sustainable investments, Asset Owners are demanding more from their data. Whether in-house or an external mandate, Asset Owners will continue to leverage data for enhanced analytics, including quantifiable KPIs, to measure performance and meet oversight obligations.

However, non-standardized data remains a barrier in sustainability, particularly in private market investments. These allocations increase the complexity of obtaining a Total Portfolio View across public and private holdings, requiring innovative solutions to address data sourcing and integration challenges.

• The challenge: Asset Owners require a well-defined data strategy, governance and supporting architecture to aggregate and analyze diverse information sources across risk, return, and sustainability metrics. Critical to success is a clear link between data strategy and business outcomes, a thorough understanding of current state data domains / models and a clear roadmap, inclusive of integrating any new third-party solutions.

3. Reporting

Leveraging data with effective sustainability reporting remains a key challenge as the industry shifts toward objective and outcome-based reporting, to enhance accountability and combat greenwashing. This is particularly prevalent with Active Ownership & Stewardship, tracking and reporting of thematic outcomes. Asset Owners must link performance and ROI to their sustainability strategy and objectives, using standardized data, tooling and processes.

Reporting requirements vary based on investment approaches. While some Asset Owners integrate ESG considerations into broader strategies, others implement strict screening criteria or target specific tangible impacts. Adhering to indexes, frameworks, and voluntary standards ensures accountability to policyholders, trustees and partner investors.

• The challenge: There is no “one size fits all” solution for sustainability reporting: Asset Owners must have a clear vision and end-to-end process that is underpinned by data capabilities. Navigating the landscape of reporting solutions and outsource models, as well as designing an operating model that integrates reporting systems effectively into the value chain (e.g. leveraging automation opportunities) can be a complex challenge.
