What is ESG?
ESG Investing is a term that is often used synonymously with sustainable investing, socially responsible investing, mission-related investing, or screening. At MSCI ESG Research we define it as the consideration of environmental, social and governance factors alongside financial factors in the investment decision-making process.
Under the ESG investing umbrella, MSCI ESG Research has identified three common investor objectives or motivations when considering an ESG strategy: Integration, Values and Impact. In order to achieve these objectives, institutional investors may pursue different approaches such as ESG integration, exclusionary or negative screening, or thematic investing, to name a few. While this is not a comprehensive glossary of all ESG terms in the market, we provide an overview of several commonly used terms and their definitions below.

Investors may consider a number of different ESG factors, metrics and data when looking to adopt an ESG investing strategy or apply ESG across a portfolio. These factors typically include industry-specific key issues such as climate change, human capital and labor management, corporate governance, gender diversity, privacy and data security, among others. A mining company and a financial company, for example, may be faced with different key ESG risks and opportunities and therefore evaluated on the key issues specific to their respective industries.

The Evolution of ESG Investing
ESG is growing in significance amongst both institutional and retail investors. The practice of ESG investing began in the 1960s as socially responsible investing, with investors excluding stocks or entire industries from their portfolios based on business activities such as tobacco production or involvement in the South African apartheid regime.
Today, ethical considerations and alignment with values remain common motivations of many ESG investors but the field is rapidly growing and evolving, as many investors look to incorporate ESG factors into the investment process alongside traditional financial analysis.

Why is ESG Investing Growing?
Why is ESG Investing Growing?
In recent years, institutional investor adoption of ESG and the subsequent growth in ESG assets under management has accelerated.1 While much has contributed to this growth, we focus on three primary drivers of ESG investment.
“This virtuous combination of burgeoning demand and investment rationale will drive the ESG asset pool’s rapid growth…ESG outcomes are likely to become an integral part of investment solutions, and ESG analysis an essential investment tool.” – PwC Report, Asset & Wealth Management Revolution: Embracing

Global sustainability challenges such as flood risk and sea level rise, privacy and data security, demographic shifts, and regulatory pressures, are introducing new risk factors for investors that may not have been seen previously. As companies face rising complexity on a global scale, the modern investor may reevaluate traditional investment approaches.
Over the next two to three decades, the millennial generation could put between $15 trillion and $20 trillion into U.S.-domiciled ESG investments, which would roughly double the size of the U.S. equity market.2 A growing body of studies suggest that millennials - as well as women - are asking more of their investments.

With better data from companies combined with better ESG research and analytics capabilities, we are seeing more systematic, quantitative, objective and financially relevant approaches to ESG key issues. Better data and analytics have paved the way for numerous studies that explore ESG investing (see: Does ESG add value?).
MSCI ESG Research provides research and ratings on over 13,000 equity and fixed income issuers linked to over 590,000 equity and fixed income securities on a ‘AAA’ to ‘CCC’ scale according to their exposure to industry specific ESG risks and their ability to manage those risks relative to peers.

LEADING INSTITUTIONAL INVESTORS ARE INCORPORATING ESG FACTORS INTO THE INVESTMENT PROCESS
Leading institutional investors are incorporating ESG factors into the investment process
Since its founding in 2006, the United Nations Principles for Responsible Investing (PRI) has attracted support from more than 1,800 signatories representing over USD $68 trillion in assets under management as of April 2017. Signatories commit to six voluntary principles, the first of which is the incorporation of ESG issues into investment analysis and decision-making.

Has ESG Historically Compromised Financial Returns? NEW
Has ESG Historically Compromised Financial Returns?
A common debate with ESG investing revolves around the idea that incorporating ESG factors into the investment process will hurt performance. However, some studies suggest that companies with robust ESG practices displayed a lower cost of capital, lower volatility, and fewer instances of bribery, corruption and fraud over certain time periods. Conversely, studies have shown that companies that performed poorly on ESG have had a higher cost of capital, higher volatility due to controversies and other incidences such as spills, labor strikes and fraud, and accounting and other governance irregularities.7
It may come as no surprise then that numerous academic and investor studies (see below) in recent years have found historically lower risk and even outperformance over the medium to long term for portfolios that integrated key ESG factors alongside rigorous financial analysis.
In a recent study, MSCI researchers focused on understanding how ESG characteristics have led to financially significant effects. The study examined how ESG information embedded within stocks is transmitted to the equity market. Borrowing from central banks, we created three “transmission channels” within a standard discounted cash flow (DCF) model. We call these the cash-flow channel, the idiosyncratic risk channel and the valuation channel. The former two channels are transmitted through corporations’ idiosyncratic risk profiles, whereas the latter transmission channel is linked to companies’ systematic risk profiles. Our research showed that ESG had an effect on valuation and performance of many of the companies in the study.
We identified three major channels from ESG to financial value. Companies with higher ESG ratings were associated with:

The positive impact of ESG investing on bond performance
The historically positive impact of ESG on performance has not been limited to equities. In a 2016 study, Barclays found “that a positive ESG tilt resulted in a small but steady performance advantage” and that “no evidence of a negative performance impact was found.

ESG in Emerging Markets
ESG in Emerging Markets
Investing in emerging markets can carry a high degree of risk, not least from the threat of environmental, social and political instability. Research suggests that "tail risk" - the risk of unlikely events causing catastrophic damage - may be reduced in an emerging markets portfolio that has limited its exposure to these ESG risks. 8,9
Emerging market asset managers keen to utilize ESG analysis have historically faced significant information problems; however, with the introduction of stewardship codes in the Asia Pacific region and an emphasis on reporting and disclosure globally, this is changing.
MSCI ESG Ratings are used in the construction of many of MSCI's 900 ESG Indexes.
The MSCI ESG Leaders Indexes are designed to represent the performance of companies that have high Environmental, Social and Governance (ESG) performance. The MSCI ESG Leaders Indexes aim to target sector weights that reflect the relative sector weights of the underlying indexes to limit the systematic risk introduced by the ESG selection process.
The MSCI Socially Responsible Investing (SRI Indexes) are designed to exclude companies that are inconsistent with specific values-based criteria focused on products with high negative social or environmental impact and to target companies with high Environmental, Social and Governance (ESG) ratings relative to their sector peers, to ensure the inclusion of the best-in-class companies from an ESG perspective. Further, these Indexes aim to target sector weights that reflect the relative sector weights of the underlying MSCI Global Investable Market Indexes to limit the systematic risk introduced by the ESG selection process.

I believe that incorporating ESG may improve my investment results.
Growing research suggests that ESG factors have contributed to long-term financial performance. ESG factors can be used to identify better-managed companies or to flag companies with business models that are likely to face headwinds or tailwinds driven by rapidly evolving regulatory, environmental, demographic or technological trends. Institutional investors are increasingly looking to ESG factors as a way to manage these risks and to achieve long-term sustainable financial performance.10

My investments should reflect my values.
Some investors consider ESG issues a means for aligning investments with their ethical, religious or political beliefs. They have typically used ESG research to screen for controversial activities such as tobacco, weapons, alcohol, gambling or fossil fuels, and to help exclude such activities from their investment universe. Unlike the ESG integration goals described above, where ESG factors are considered on the basis of their potential economic impact, values-based goals are intentionally aligned to match an investor’s beliefs.

Paper: Foundations of ESG Investing – Part 2: Integrating ESG into Benchmarks
May 3, 2018 Guido Giese, Linda-Eling Lee, Dimitris Melas, Zoltan Nagy, Laura NishikawaAn ad hoc approach to ESG integration can lead to suboptimal results. Instead, a top-down approach can afford greater consistency throughout the entire portfolio. So can ESG indexes be used as benchmarks, both for the total portfolio and individual allocations? We test whether two such ESG indexes can be used for these purposes, using the MSCI ESG Leaders Index — a "best-in-class" approach that selects index constituents with strong ESG ratings — and the MSCI ESG Universal Index — a re-weighting methodology that relies on ESG ratings and changes in ESG ratings.
