ESG data is transforming investment strategies by helping identify risks, refine returns, and meet regulatory demands. Here's how it works:
By integrating ESG data into your investment approach, you can make better-informed decisions while addressing evolving market and regulatory pressures.
Reliable ESG data sources are essential when incorporating sustainability into portfolio management. The market features several well-known providers, each with its own methods and areas of focus. For example, MSCI covers over 17,000 issuers and works with 96 of the world's top 100 asset managers. It gathers an average of 4,000 raw data points per issuer across its sustainability and climate products. Other major players include Sustainalytics, ISS (Institutional Shareholder Services), CDP (formerly Carbon Disclosure Project), and S&P TruCost. These platforms typically provide scores for specific issues, such as carbon or water risks, alongside broader governance ratings.
However, these providers often rely on different methodologies, making direct comparisons tricky. This highlights the importance of understanding how their data is collected and verified. Below, we explore some of the leading providers and their approaches.
Each major provider serves a distinct role within the ESG landscape. MSCI, for instance, focuses on evaluating companies' resilience to financially relevant sustainability risks and opportunities that vary by industry. On the other hand, CDP takes a unique approach by conducting primary research, including interviews with management teams, rather than relying solely on voluntary disclosures. This can reveal risks that more traditional methods might overlook.
The choice of provider often hinges on the ESG factors most relevant to a portfolio. Some platforms prioritise carbon emissions and climate-related data, while others concentrate on workforce diversity, supply chain practices, or board composition. For sector-specific insights, providers using industry-focused scoring systems tend to deliver more tailored and actionable information than those offering generalised ratings.
Assessing the reliability of ESG data involves a few key considerations. Third-party verification is a vital indicator - high-quality assurance should clearly outline the scope of the data reviewed and the conclusions drawn. Additionally, alignment with established international frameworks, such as the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), and Principles for Responsible Investment (PRI), adds another layer of credibility.

In the UK, regulatory frameworks further reinforce data reliability. The Sustainability Disclosure Requirements (SDR), introduced by the Financial Conduct Authority (FCA), provide voluntary labels like Sustainability Focus and Sustainability Impact. These labels require at least 70% of assets to align with specific sustainability objectives, helping investors identify products that meet rigorous standards. Additionally, the FCA's anti-greenwashing rule, effective from May 2024, mandates that sustainability claims must be fair, clear, and not misleading.
When choosing a data provider, investors should prioritise those that rely on primary research, maintain transparent methodologies, and incorporate alternative data sources beyond traditional corporate disclosures. This ensures the information supports well-informed and responsible investment decisions.
Centralised vs Decentralised ESG Data Frameworks Comparison
Once you've secured reliable data sources and confirmed their accuracy, the next step is weaving ESG metrics into your portfolio management strategy. This isn’t just about meeting sustainability goals - it’s also about improving risk-adjusted returns.
To incorporate ESG metrics effectively, consider screening out low-performing assets and reallocating investments to high scorers. At the same time, maintain regional and sectoral balance to minimise tracking error. Research backs this approach: stocks with strong ESG performance have been shown to outperform the market by up to 3 percentage points annually over five years. This suggests that ESG integration can uncover fresh opportunities for alpha, such as identifying links between diverse management teams and enhanced company performance.
The way you organise ESG data can make a big difference in terms of efficiency and scalability. A centralised framework consolidates all data into a single repository, or "data lake", which simplifies access for portfolio managers. This setup is particularly useful for regulatory reporting, such as compliance with the EU's Sustainable Finance Disclosure Regulation (SFDR). However, it might fall short when dealing with niche or qualitative ESG factors. By centralising, you ensure consistency and streamline management, but at the cost of flexibility for specialised datasets.
On the other hand, a decentralised framework relies on multiple vendors, each providing data for specific needs. For instance, one vendor might supply raw data, while another focuses on estimates. This approach taps into specialised expertise - such as providers focusing on carbon emissions or green bonds - and broadens your investment possibilities. The downside? Merging and normalising data from various sources can be complex and resource-intensive due to differing methodologies.
| Framework Type | Advantages | Drawbacks |
|---|---|---|
| Centralised | Simplifies data access and ensures consistency for compliance purposes. | May lack flexibility for unique or niche datasets. |
| Decentralised | Offers customisation and access to specialised expertise. | Requires significant effort to reconcile and normalise data, increasing complexity. |

Once your data framework is in place, automating the integration process can save time and reduce errors.
Manual data handling is not only time-consuming but also prone to mistakes. Automation tools, such as APIs, make retrieving ESG scores and financial data much more efficient. For instance, Refinitiv's Eikon Desktop Data API, when paired with Python-based Jupyter Notebooks, has been used to automate backtesting ESG-focused strategies. The results? Companies with ESG scores above 70 outperformed the broader market by 3% annually over five years.
Artificial intelligence (AI) and natural language processing (NLP) take this a step further by analysing unstructured data - like news articles, social media posts, or earnings calls. These tools can detect sentiment and flag ESG risks before they affect stock prices. AI’s ability to process vast amounts of multilingual data helps address gaps in incomplete or unverified datasets. For example, the Sustainable Development Investment Asset Owner Platform (SDI AOP), which represents asset owners managing £1.2 trillion, uses AI to align company activities with the UN Sustainable Development Goals.
Platforms like Zapflow enhance efficiency further by automating ESG data collection, analysis, and reporting. By integrating ESG metrics into a unified portfolio management system, Zapflow allows investment teams to track sustainability performance in real time. This ensures ESG considerations are embedded throughout the investment process, rather than being treated as an afterthought.

Once you've integrated ESG data, the next step is to analyse it to uncover both risks and growth opportunities. ESG scores often combine a variety of factors, which can make it challenging to pinpoint what drives a particular rating. To get a clearer picture, break down these aggregate scores into their environmental, social, and governance components. This approach helps identify the specific areas influencing performance.
A materiality assessment is crucial here. It helps determine which ESG factors genuinely affect a company’s financial performance or operational stability. Not all ESG issues carry the same weight. For example, carbon emissions might be a critical concern for an energy company but have far less impact on a software business. Tailor your analysis by focusing on material ESG factors that align with a company’s sector or operations. This approach not only helps mitigate risks but can also uncover high-growth opportunities.
Let’s take a closer look at how to measure risks and identify opportunities using ESG analysis.
ESG data can reveal risks that traditional financial analysis might miss, such as regulatory violations, reputational harm, or unsustainable practices. By examining detailed data, you can identify vulnerabilities like poor governance or labour issues that might lead to penalties or disrupt operations.
One popular method is negative screening, where companies with the lowest scores in specific ESG categories are excluded to reduce exposure to unsustainable practices. However, this strategy can introduce biases based on region or sector if not applied carefully. An alternative is the best-in-class strategy, which excludes the lowest performers in an ESG category but reinvests in the top performers within the same sector or region. Research suggests this approach can significantly improve ESG scores with minimal impact on financial returns compared to broader market benchmarks.
"ESG scores... amalgamate a broad range of fundamentally different factors, creating ambiguity for investors as to the underlying drivers of higher or lower ESG scores."
– IMF Working Paper
Beyond managing risks, ESG data can also point to areas of growth. For instance, tracking megatrends like natural resource shortages (e.g., potable water) or shifting demographics (e.g., millennials favouring sustainable products) can help identify sectors primed for expansion. Dissecting ESG scores allows you to spot these trends more clearly, enabling targeted investment strategies rather than broad, generalised approaches.
ESG data can also highlight companies at the forefront of innovation in areas like renewable energy, circular economies, or diverse leadership teams - factors often linked to stronger performance. Instead of relying solely on exclusionary tactics, consider ESG integration. This involves embedding sustainability factors into traditional financial analysis, offering a more comprehensive view of an investment’s risk and return potential.
"Systematically considering ESG issues will likely lead to more complete investment analyses and better-informed investment decisions."

Once you've assessed ESG data for risks and opportunities, the next step is to translate these insights into actionable investment decisions. This involves moving from passive analysis to actively reshaping your portfolio based on the information uncovered. It's about aligning your asset allocation and investment choices with the ESG risks and opportunities revealed by the data.
A structured framework is key here - one that balances financial returns with ESG considerations. One effective method involves adjusting the "expected utility" of each investment. This calculation factors in the expected return, traditional risks like volatility, and an ESG risk score. By doing so, you optimise your portfolio across three dimensions: financial return, investment risk, and ESG risk, rather than treating sustainability as an optional extra.
Before implementing any ESG-driven strategy, it's crucial to clarify your objectives. Are you using ESG data to align with your values, or are you leveraging it to refine risk and return predictions? This distinction will shape which ESG factors you prioritise and how they integrate into your decision-making process.
"ESG data or ESG factors are actually being used as an additional signal alongside traditional financial considerations to reduce risk and improve returns"
– Linda-Eling Lee, Managing Director and Head of ESG and Climate Research at MSCI
Using your established ESG metrics, you can adjust asset allocations to reflect both sustainability goals and financial performance.
You don't have to choose between ESG performance and financial returns - they can complement each other. Studies show that excluding companies with the lowest ESG scores in a specific category can significantly improve that category's score with only a minimal effect on financial performance when compared to a broad market benchmark.
One effective approach is the best-in-class strategy. Instead of excluding poor ESG performers outright - which can lead to sectoral or regional biases - this strategy reinvests in top ESG performers within the same sector or region. This ensures a balanced portfolio while maintaining ESG priorities.
Focusing on materiality is crucial. Not all ESG factors carry the same weight across industries. For example, water scarcity is a pressing issue for semiconductor manufacturers, while carbon emissions are a top concern for utilities. By concentrating on financially material factors relevant to each sector, ESG data becomes a tool for identifying long-term value rather than applying a one-size-fits-all approach.
Conducting trade-off analyses can help you assess how varying ESG sensitivities might impact returns. This step allows you to quantify potential outcomes and justify your decisions to stakeholders with greater confidence.
These principles set the foundation for practical implementation, as illustrated by the following examples.
Private equity and venture capital offer unique opportunities to leverage ESG insights. Unlike public market strategies, these investors can directly influence boards, access confidential ESG data, and implement immediate changes.
Take the Light Smith Group, for instance. In 2023, this sustainable private equity firm, co-founded by Jay Koh, invested in Source Global. The company uses solar-powered hydro panels to produce drinking water from air - a solution aimed at addressing climate challenges. Light Smith Group employs an Environmental Social Monitoring System (ESMS) based on IFC performance standards to manage risks like labour issues and governance failures. At the same time, they measure non-financial impacts, such as water production in drought-prone areas. This approach demonstrates how ESG insights can drive both risk management and value creation.
On the flip side, overlooking ESG risks can have severe consequences. In 2019, PG&E (Pacific Gas and Electric), the 10th largest utility in the United States, filed for bankruptcy due to liabilities from devastating wildfires.
"This was not something most investors expected to be a risk when they bought municipal bond"
– Jay Koh
For effective implementation, it's important to differentiate between types of ESG risks. Physical risks involve location-specific modelling to determine how assets - like factories or coastal properties - might be affected by climate hazards over the long term (30–70 years). Transition risks, on the other hand, focus on assessing the impact of policy changes, carbon taxes, or the shift to renewable energy on a company's cost structure or market position.
These examples show how ESG insights can be a powerful tool for managing risks and identifying opportunities in investment strategies.
Once ESG insights are part of your investment decisions, the next hurdle is ongoing monitoring and transparent reporting. Many investment teams face challenges here - manual data compilation often causes delays and increases the chance of errors. A centralised platform can turn this quarterly struggle into a smooth, efficient process, enabling real-time ESG reporting.
By creating a consistent framework for ESG data collection and reporting, General Partners (GPs) can ease their workload and improve communication with Limited Partners (LPs). Instead of starting from scratch each quarter, technology platforms can map your data directly to major global disclosure frameworks like SASB, GRI, TCFD, and SFDR. This not only simplifies compliance but also enhances transparency.
Zapflow's Portfolio Management tool eliminates the need for spreadsheets and email chains by centralising your ESG data. Key performance indicators (KPIs) across your portfolio are tracked in one place, reducing errors and saving valuable time.
Automation takes it a step further, improving data accuracy. Using AI and machine learning, Zapflow automates tasks like extracting data from PDFs, websites, and questionnaires, while also pulling in benchmarking data for easy comparison. This means you can produce accurate ESG performance reports for internal teams and external stakeholders without the time-consuming manual input that typically slows down the process.
The platform also allows you to align your disclosures with global regulatory frameworks such as the Corporate Sustainability Reporting Directive (CSRD), International Sustainability Standards Board (ISSB), and TCFD. This ensures your reports meet stakeholder expectations while staying updated with evolving regulations. Pricing starts at £199 per fund per month, scaling to match your reporting needs.
Keeping tabs on material ESG KPIs is crucial for maintaining stakeholder trust. Zapflow’s real-time tracking features offer continuous visibility into ESG compliance and performance metrics across your portfolio.
Instead of waiting for quarterly reviews, you can monitor ESG objectives as they unfold. This proactive approach helps you address potential issues early and shows LPs that you're not just reporting ESG risks but actively managing them.
Customisable dashboards give you instant access to essential metrics. For example, you can track carbon emissions in your utilities investments or monitor water usage in manufacturing companies. Real-time data enables quick responses to risks or opportunities, strengthening relationships with LPs and ensuring compliance with regulations like the EU’s Sustainable Finance Disclosure Regulation (SFDR). This level of transparency keeps your firm ahead of increasing disclosure requirements.
Using ESG data effectively is key to managing risks, identifying opportunities, and staying ahead of regulatory requirements. High-quality ESG insights can broaden your investment options while offering the potential for better returns.
To truly harness the power of ESG data, it’s important to go beyond generic scores and focus on detailed, sector-specific information. For instance, a semiconductor company’s water consumption could have a greater financial impact than its carbon emissions, whereas a utility’s emissions are critical to its future success. This level of detail paves the way for smarter, technology-driven decision-making.
Tools like Zapflow simplify ESG reporting by centralising data and automating compliance tasks. By aligning with frameworks such as CSRD and SFDR, these platforms eliminate the need for spreadsheets and endless email threads, making KPI tracking much more efficient.
"As we look to the future, the integration of ESG data in investments will not only create a competitive advantage for investment managers, but they also help to transition to a just economy."

With streamlined reporting and real-time insights, ESG integration becomes a powerful tool for achieving ethical, sustainable, and profitable outcomes. Whether it’s tackling climate risks, staying compliant with new regulations, or backing businesses that address global challenges, leveraging detailed ESG data positions your firm for lasting success in an ever-evolving investment world.
ESG data plays a crucial role in helping investors make informed decisions by shedding light on a company’s environmental, social, and governance practices. These factors often reflect a company’s long-term performance and ability to adapt to challenges. By examining ESG metrics, investors can pinpoint businesses that operate responsibly, maintain strong governance, and contribute positively to society - qualities often tied to better financial stability and reduced risks.
Incorporating ESG data into portfolio management not only helps minimise risks like regulatory shifts, reputational issues, or market fluctuations but also identifies opportunities for higher returns. For example, investments in companies with low carbon emissions or strong governance frameworks can yield better outcomes. Using ESG data thoughtfully allows investors to build portfolios that are not only more resilient but also aligned with broader sustainability goals, making it an essential part of modern investment strategies.
Comparing ESG data across different providers isn't straightforward, mainly because there’s no universal standard for calculating scores. Each provider has its own methodology, uses varied data sources, and applies unique weighting systems. As a result, the same company or asset might receive very different scores depending on the provider. This lack of consistency makes it tricky for investors to assess ESG performance with confidence.
On top of that, many ESG metrics are based on qualitative factors. These often depend on subjective judgments or incomplete disclosures, which only adds to the complexity. Regional differences in reporting standards can further skew the data, introducing inconsistencies and even bias. This leaves investors questioning what ESG scores actually represent.
To improve decision-making, there’s a growing call for clearer and more aligned ESG data. Such transparency would make it easier to compare scores across providers and lead to more informed investment choices.
Automation is reshaping how organisations handle ESG data integration and reporting. By streamlining tasks like data collection, validation, and management, it removes the need for manual processes, cutting down on errors and saving valuable time. At the same time, it ensures reliable and consistent data handling throughout the organisation.
With automated ESG workflows, companies can access real-time insights, produce more precise reports, and adjust effortlessly to changing regulatory demands. This improved efficiency not only enhances decision-making but also bolsters portfolio management strategies.
