Sustainable investing - The journey

ESG integration

The use of environmental, social and governance (ESG) factors has become a vital part of the investment process for most modern asset managers.

Robeco has integrated ESG into the investment decision-making process since 2010 and now routinely does so for its entire range of fundamental equity, fixed income, quantitative and bespoke sustainability products.

Importance of ESG integration

Financial materiality is the crucial ingredient in ESG integration. The factors being considered are not just ‘nice to have’ – they must also have a direct impact on the company’s bottom line. For example, an investor will not just look at factors such as pollution from the perspective of harming the environment. Such behavior may also have a financial impact, from attracting fines and raising costs, to regulatory risks. These factors feed through into a company’s results, and therefore into its market value.

The concept of double materiality is also important, particularly regarding a company’s climate change risk. Investors must look at what effect the company has on the world as well as what effect the world is having on the company.

ESG integration is widely seen as contributing to the ability to make the kinds of investment decisions that can identify the more sustainable companies and avoid the losers.

What is ESG integration?

ESG integration is defined by the UN Principles for Responsible Investment as: “The explicit and systematic inclusion of environmental, social and governance issues in investment analysis and investment decisions.”

Robeco usually integrates ESG in three steps:

  1. The first is to identify and focus on the most financially material issues affecting the company.

  2. Then the investor can analyze the likely impact of these factors on the company’s business model.

  3. Finally, this information can be incorporated into the valuation analysis to form a fundamental view.

This ESG analysis forms part of a wider mix of traditional metrics to value the company and its prospects. ESG investing is not the same thing, however, as impact investing. With ESG investing, the purpose is to integrate environmental, social and governance factors into the process, and then decide whether the stock or bond is worth buying. With impact investing, the purpose is to make an impact on the ground with the investment while also getting a financial return. This makes many companies unsuitable for impact strategies even if their ESG credentials are good.

ESG research as the bedrock

Core frameworks

Robeco uses the value driver-based ESG scoring approach to find the most sustainable companies in equities. This links ESG factors such as a company’s emissions, waste, labor relations and capital returns to value drivers through their expected effects on business models and competitive positions. The starting point of this linking process is having a clear understanding of the nature of the business, which should allow the analyst to identify the most material issues.


Step 1

Identify and focus on most material issues

Step 2

Analyze the impact of material factors on the business model

Step 3

Incorporate into valuation analysis and/or fundamental view

In fixed income, the ESG integration process uses the F-score framework, which analyses a company’s business position, corporate strategy, ESG profile, corporate structure and financial profile. Standard ESC scoring used for equities can help compile the ESG profile, particularly when a company issues bonds as well as stocks.

For strategies that follow the Sustainable Development Goals, we developed an SDG Framework to score companies that can contribute to them based on three issues.

For government bonds, the Country Sustainability Ranking is used to evaluate the ESG characteristics of 150 countries. This also feeds though into equities and corporate bond research, since many companies operate in more than one country, and will always be subject to the investment conditions in their domicile.

And then more specific tools can be used across all asset classes, such as our Carbon Analysis Tool which provide insight into a portfolio’s and the underlying company’s greenhouse gas emissions. Via the tool the investment teams can slice and dice emission on amongst other scopes or sector contribution. This is becoming increasingly important in trying to meet net zero targets.

A stepping stone to sustainability

In conclusion, Robeco structurally integrates financially material ESG issues into almost all of its investment processes. The aim is to achieve even better investment returns for our clients. This is a standard feature of our strategies.

Next to this standard feature, Robeco also has a lot of experience implementing client-specific sustainability characteristics into investment strategies. This includes:

  • Targeted SDG investing using the SDG scoring framework for a range of equity and credits strategies

  • Transition investing targeting companies at the forefront of the move to a low-carbon economy

  • Climate and net-zero investing that set specific decarbonization pathways for inclusion

  • Thematic investing under Article 9 of the SFDR with a specific sustainability objective such as Smart Energy

A better pay-off

The ability of more sustainable companies to better weather exogenous shocks was seen during the Covid crisis, where companies with sustainable business models actually did better than companies that do not take ESG into account.

Another example of how focusing on sustainability pays off in the long term can be seen in strategies that align with the SDGs. Robeco’s SDG Framework is used to identify those companies that can make a net positive contribution to one or more of the goals.
