What Is Sustainable Investing And Why Does It Matter?

sustainable investing

If you want to make the world a better place, then sustainable investing is the right choice for you to spare your money for a good cause. It is low-risk, high-value and has a great impact for solving environmental, social and governance (ESG) problems like climate change, social injustice and access to medicine.

Although some remain quite skeptical about the real ROI of sustainable investments, they still remain a popular choice. According to the Sustainable Signals report, 79% of all investors showed interest in sustainable investing, and climate change remains a top focus, with 93% of individual investors keen on climate-themed investments.

In 2023, ESG funds remained popular and even made their way to political debates, raising concerns about retirement plans in the US. The biggest players have varied investment portfolios and strict ESG criteria on what firms they work with. For example, Vanguard ESG U.S. Stock ETF (ESGV), with 70% of their holdings being large-cap stocks, do not intervene with entertainment, alcohol, tobacco, cannabis, gambling, weapons, coal, oil, gas, or nuclear power firms.

In this article, we will delve into what sustainable investing is at its core, compare it against traditional methods, highlight the benefits of ESG funds, and suggest some strategies to get it going.

What Is Sustainable Investing?

Sustainable investing, also known as socially responsible investing (SRI) or impact investing, is an investment approach that considers both financial returns and ESG factors. It aims to generate long-term value while promoting positive societal and environmental outcomes.

In sustainable investing, investors seek to align their choices with their values and the broader goals of ‘green’ and ‘fair’ operations. They prioritize companies that demonstrate strong ESG practices, such as those committed to reducing carbon emissions, promoting diversity and inclusion, and ethical business politics.

For example, a sustainable investor may choose to invest in a renewable energy company that develops solar or wind power projects. This venture not only offers potential financial returns but also supports the transition to clean energy, reduces reliance on fossil fuels, and contributes to mitigating climate change.

Overall, sustainable investing recognizes the interconnectedness between financial performance and sustainability, allowing investors to drive positive change while pursuing their investment objectives. It encourages companies to adopt responsible practices and contributes to a more equitable future.

Traditional vs. Sustainable Investing

Traditional and sustainable investing are two distinct approaches with different focuses and outcomes. Here’s a breakdown of the key differences between the two:

Traditional Investing

Traditional investing primarily prioritizes financial returns and profit maximization. Investors seek opportunities that offer the highest potential for capital growth and financial gains. This approach often involves analyzing historical cash flow performance, market trends, and company fundamentals to identify attractive investment options.

For example, a traditional investor may choose to invest in a company solely based on its profitability, market share, or potential for growth, without considering its environmental or social impact.

Sustainable Investing

Sustainable investing, on the other hand, goes beyond financial returns and incorporates ESG factors into investment decisions. It aims to generate a positive impact alongside good ROI. Sustainable investors consider a company’s sustainability practices, such as its carbon footprint, labor standards, community engagement, and corporate governance, to assess its long-term viability.

Sustainable investing strategies can take various forms. For instance, negative screening excludes companies involved in controversial activities. On the flip side, positive screening is based on searching for ones with strong ESG performance. There is also thematic investing where investors target specific sustainability themes like clean energy or gender equality). Last but not least, impact investing is all about projects or companies with measurable social or environmental outcomes.

The Benefits of Sustainable Investing

Sustainable investing offers several benefits beyond financial returns. It allows investors to align their investments with their values and contribute to positive change. By allocating capital to companies with strong ESG practices, investors can drive improvements in corporate behavior and support the transition to a more sustainable economy.

Additionally, sustainable investing can help mitigate risk by considering non-financial factors that may impact a company’s long-term performance. For example, companies with poor environmental practices may face regulatory challenges or reputational risks that can affect their financial stability.

In recent years, sustainable investing has gained significant momentum as investors increasingly recognize the importance of incorporating sustainability considerations into their strategies. This approach represents a shift towards a more holistic view of investment performance, one that not only generates financial returns but also contributes to a better future.

What Are The 4 Strategies of Sustainable Investing?

There are four primary strategies commonly used in sustainable investing. Here’s an overview of each one:

  1. Screening and Exclusion
  2. Integration
  3. Thematic Investing
  4. Impact Investing

Screening and Exclusion

This strategy involves screening out companies or sectors that do not meet specific ESG criteria. It focuses on excluding investments that engage in activities considered harmful, such as tobacco production, weapons manufacturing, or environmental pollution. By avoiding these industries, investors align their portfolios.


Integration strategy involves incorporating ESG factors into traditional investment analysis. Investors consider ESG risks and opportunities alongside financial metrics when evaluating potential investments. This way, they can gain a deeper understanding of a company’s long-term prospects and potential risks, leading to more informed investment choices.

Thematic Investing

Thematic investing focuses on specific sustainability themes or sectors that align with an investor’s values or long-term objectives. Examples of thematic investing include investing in renewable energy, clean technology, water conservation, or gender equality initiatives. By targeting specific sustainability themes, investors can direct capital towards areas that address pressing environmental or social challenges.

Impact Investing

Impact investing involves allocating capital to projects, companies, or funds with the intention of generating measurable positive social or environmental outcomes alongside financial returns. This strategy seeks investments that create tangible, beneficial impacts, such as investing in affordable housing, education initiatives, or sustainable agriculture. Impact investors aim to achieve a balance between financial returns and measurable positive change.


As you can see, investing doesn’t have to be all about financial goals only. Through social responsibility and a strive for a better, sustainable and fair future, it can indeed be a way to solve serious environmental and social problems that affect humanity. By following ESG practices, sustainable investors spread an important message across the corporate world – that capital gains are insignificant if not intertwined with moral values.
