How Nuveen Uses Responsible Investing Across Asset Classes to Seek Higher Returns and Manage Risks

Updated: Feb 22, 2023

Improving existing investment processes by integrating ESG factors can achieve something all investors strive for: achieving greater return potential, mitigating portfolio risks and unlocking new opportunities.

At Nuveen, we have over 50 years of experience in RI, and a proven history of generating returns through all market cycles. But RI is not just part of our history, it is an integral part of our future. Please contact us to learn more about our wide range of responsible investing offerings, spanning both public and private markets.

Indeed, successfully forecasting long-term market, sector and entity-specific trends increasingly requires a comprehensive understanding of relevant ESG factors and their potential financial effects. Today, intangible assets, such as brand equity, customer and supplier relationships and public rights, comprise 84% of the total market value of the S&P 500, according to research from the Ponemon Institute. This means that poor ESG management in focus areas, such as human capital, supply chains, board independence, natural resource usage or environmental impacts can have significant implications for a company’s bottom line and risk profile.

Yet, while financially material, these factors are difficult to assess solely through traditional financial analysis. As an asset manager with a global, diversified investment platform, we use ESG factors to expand the scope of data and analysis we use to inform decision-making, portfolio construction and management. Through ESG integration, we seek to enhance performance, avoid or ameliorate risks and broaden opportunities.


Delivering the investment benefits of ESG integration requires incorporating ESG factors throughout the lifecycle of the investment. Our investment teams follow a consistent framework that drives ESG incorporation across the research/ due diligence, portfolio management, monitoring and reporting stages of investment. However, processes can be customized with the tools and data needed for each asset class.

In collaboration with our dedicated RI team, investment analysts and portfolio managers across Nuveen have worked to:

• Map relevant ESG factors across industry sectors

• Deepen their understanding of the connection between ESG and risk/return

• Expand their use of ESG data and insights

• Capitalize on technology-enabled solutions to access expansive ESG datasets and streamline processes

• Develop and share proprietary ESG ratings


We systematically integrate ESG information across a range of equity investment strategies. In public equities, company ESG risks, such as product quality and safety issues or increased expenses associated with regulatory requirements, are relevant to future projected cash flows and can be captured in analysts’ financial models. An ESG lens can also help to identify opportunity. Companies aligned with positive ESG trends, such as clean energy, data security, human capital management or health and wellness may experience above- industry average growth and profitability, which can also be captured in valuation.

Through ESG research, analysts can develop conviction around ESG themes or factors and, ultimately, combine these insights with fundamental analysis to inform investment decision-making and portfolio construction.

We address outstanding ESG-related issues through direct engagement with company boards and executive management to drive improvement and transparency. These interactions provide further inputs for ongoing investment analysis and support changes that we believe will help to mitigate corporate risks and drive shareholder value.


We evaluate municipal issuers’ ESG performance using a proprietary ESG scoring methodology. Developed jointly between our municipal credit research and RI teams, our ESG municipal scores measure issuers’ performance on ESG outcomes specific to their sector. For example, we may assess cities on outcomes like air quality and crime rates, while we would look at water pollution and age of infrastructure assets for water and sewer utilities.

In addition to collaborating on the development and continuous improvement of the ESG scoring models, the municipal investment team considers the ESG score as a factor in the investment process. We believe ESG performance is positively correlated with credit quality, and think it is a unique signal that allows the investment team to distinguish between otherwise similar municipal credits. When paired with Nuveen’s in-depth fundamental municipal credit expertise, ESG integration becomes a powerful tool to enhance our investment process.


While responsible investing may have gained traction earlier in public equity, in recent years there has been swift expansion of these RI considerations across all sectors of taxable fixed income. We have been a pioneer in ESG integration across our own fixed income portfolios with research analysts and portfolio managers building conviction through systematic approaches.

Corporate bonds. Our taxable fixed income research team assigned proprietary ESG ratings to over 1,400 corporate issuers across emerging markets, high yield and investment grade corporate debt. The proprietary ESG ratings capture our taxable fixed income views on ESG leaders and laggards within credit sector and industry. By developing ESG expertise within the credit research team, we are institutionalizing the use of ESG factors in our research process.


ESG integration for private equity and private credit requires a different approach from public markets due to lack of ESG disclosure among private companies. This limits the availability of third-party research and ratings, and requires that we undertake these processes in-house.

As one of the first private market managers to develop internal, proprietary ESG ratings, our investment analysts take a data-driven approach to evaluating and influencing ESG performance at the investment and portfolio level. This drives both accuracy and transparency with the investment committee as well as effective oversight and management of ESG issues throughout investment lifecycles that are measured in years, rather than quarters.


We consider incorporating ESG factors in real estate a fundamental requirement, given the needs and desires of owners, occupiers, developers and investors. Green buildings that are resilient to climate change are lower risk and more attractive to tenants and investors alike. Strong investor returns and community socioeconomic outcomes can go hand in hand. By considering the needs of local communities, building owners benefit from overall economic growth and prosperity. Heightened ESG pressures, growing responsibilities and new opportunities in the markets of tomorrow are of primary focus as we seek to future-proof our real estate portfolio.


Investments in real assets can often last 20 years or more. As such, these investments go through rigorous due diligence and monitoring processes that take into account ESG risks and opportunities specific to geography, climate, crop type(s) and agricultural context. Climate risk and other environmental factors are particularly relevant to the performance of assets like farmland, as natural resource use, extreme weather events, rising temperatures and shifting weather patterns can have profound impacts on production. Additionally, assessing and appropriately managing social factors, such as land ownership rights and labor standards, are vital to ensuring our right to operate and ability to drive output.

A word on risk

All investments carry a certain degree of risk and there is no assurance that an investment will provide positive performance over any period of time. Investing in municipal bonds involves risks such as interest rate risk, credit risk and market risk, including the possible loss of principal. The value of the portfolio will fluctuate based on the value of the underlying securities. There are special risks associated with investments in high yield bonds, hedging activities and the potential use of leverage. Portfolios that include lower rated municipal bonds, commonly referred to as “high yield” or “junk” bonds, which are considered to be speculative, the credit and investment risk is heightened for the portfolio. Bond insurance guarantees only the payment of principal and interest on the bond when due, and not the value of the bonds themselves, which will fluctuate with the bond market and the financial success of the issuer and the insurer. No representation is made as to an insurer’s ability to meet their commitments.
