The History of Socially Responsible Investing

Impact Investing

Many investors are choosing to align their portfolios with their personal values, using their investments to make a positive impact.

While socially responsible investing might seem like a new phenomenon due to its rapidly growing popularity, its earliest origins trace as far back as the first books of the bible.

The history of SRI

The earliest precursors of socially responsible investing date back to the Pentateuch – the first five books of the Bible, believed to have been written by Moses as early as 1500 BC. The books refer to a Jewish concept called Tzedek (justice and equity) and how it should govern all aspects of life. Tzedek aimed to correct the imbalances that humans inevitably generate, including the benefits one would receive from ownership. Owners had rights and responsibilities in how holdings were used, one of which was to prevent any immediate or potential harm.

This principle formed the genesis of socially responsible investing, providing religious and indigenous cultures with a set of criteria on how to generate financial returns ethically and sustainably.

Religious roots and origins of socially responsible investing

Despite a consensus that ethics were an essential consideration for investment decisions, the application of the principle varied; some groups used it as a guideline, others required it by law. The basis for SRI varies between religious groups, leading to many different interpretations of the subject.

Judaism (1500-1300BC)

As mentioned above, Judaism sees a need for justice/equity in all aspects of life, including government and economic activity. Jewish Law states that investments make us property owners, giving us the responsibility to use our holdings to prevent immediate and potential harm.

While most biblical and rabbinic sources refer to single owners or small partnerships, Jewish religious figures eventually addressed the ethics of shareholder responsibility. Since shareholding is a form of ownership, investors must consider the ethical responsibilities of a company before investing. This prevented followers from investing in “immoral” companies such as those involved in oil, coal and gas because of their immediate impact on human health.

Islam (609-632CE)

The Qur’an established guidelines surrounding investments based on the teachings of Islam, now known as Shariah-Compliant Finance. This philosophy aims to govern the relationship between risk and profit, along with the responsibilities of institutions and individuals. It states that money should be a medium of exchange, not an asset that grows over time.

One of the governing principles in the Qur’an is Riba, which aims to prevent exploitation from the use of money. It prohibits the payment or receipt of all forms of usury, including all sorts of interest payments, gambling or uncertainty. The Qur’an also forbids any Islamic institution or individual from investing in alcohol, pork products, immoral goods, gold & silver and weapons.

Quaker (1650s)

Based in England since the 1650s, Quakers are members of a group called The Religious Society of Friends. While the group is primarily interested in Christianity, it is also known for its opposition to slavery and war.

In 1758, the Quaker Philadelphia Yearly Meeting prohibited members from participating in the slave trade, marking one of the first occurrences of SRI in its current form. Eventually, some Quakers went on to establish two of the largest financial institutions in modern history: Barclay’s and Lloyd’s.

Methodist (1700s)

Established in 1703, the Methodist movement was led by a man named John Wesley, one of the most articulate early adopters of SRI. During a sermon titled “The Use of Money”, Wesley outlined his stance on social investing; avoid industries that have the potential to harm workers and any business practices that might harm your neighbor. Followers eventually resisted investments in “sinful” companies, such as those involved in tobacco, firearms and alcohol. A prelude to modern exclusionary investment screening.

Modern Era: The rising popularity of SRI

The modern version of SRI in America really took hold in the mid 1900s, when investors began to avoid “sin” stocks – companies that dealt in alcohol, tobacco or gambling. In 1950, the Boston-based Pioneer Fund, established in 1928, doubled down on this movement, becoming one of the first funds to adopt SRI principles.

The avoidance of sin stocks in the 1950s marked the beginning of the rise of modern socially responsible investing, each decade bringing forth an influx socially concerned investors:


Socially responsible investing in the 1960s was largely driven by politics and concerns about the Vietnam War. Protestors boycotted companies that provided weapons for the war, while groups of students demanded university endowment funds no longer invest in defense contractors.

Meanwhile, civil rights, environmental and labor movements raised awareness about social, environmental and economic issues, bridging the gap between corporate and investor responsibility. In support of these movements, trade unions like the United Mine Workers and the International Ladies’ Garment Workers’ Union deployed targeted investments into medical facilities and union-built housing projects.


In April of 1970, 20 million Americans convened for the first Earth Day celebration, opening the door for a cascade of environmental and consumer protection legislation in the early 1970s. As society reacted to war, sweatshops, Apartheid, climate change, human trafficking and a number of other political and cultural issues, socially responsible investors followed suit.

Supported by consistent efforts from both investors and corporations, it was clear that the SRI movement was here to stay. A growing number of new funds combined social and environmental consciousness with financial objectives, reflecting the prevalence of aspirational progressive values. The Pax World Fund and the First Spectrum Fund were established in 1971, followed by the Dreyfus Third Century Fund, firmly backed by over $25 million.


In the wake of the Bhopal, Chernobyl and Exxon Valdez disasters, concerns about the environment and climate change were at the core of SRI in the 1980s. This led to the launch of The United States Sustainable Investment Forum (SIF) in 1984, which has now become one of the largest resources for SRI and impact investing.

The standardized approach to SRI in the 1980s involved building a portfolio that behaved like the traditional market while avoiding investments in alcohol, tobacco, weapons, gambling and environmental pollution. Firms paired these avoidance screens with a commitment to shareholder activism, a practice that allowed shareholders to leverage ownership to improve a company’s behavior.


By 1990, the popularity of SRI mutual funds and socially conscious investing hastened the need for a way to measure performance. Launched in 1990, The Domini Social Index (which is now the MSCI KLD 400 Social Index), was comprised of 400 U.S. publicly-traded companies that met certain social and environmental standards. Many potential investors were concerned that socially responsible investments would have lower returns than traditional investments, but this index helped to disprove those claims.

2000s and beyond (UN SDG)

By the early 2000s, socially responsible investing continued to gain supporters, alongside the introduction of many major initiatives and funds. In 2006, the United Nations Principles for Responsible Investment was launched, establishing guidelines for mainstream investors to incorporate ESG (environmental, social and governance) issues into investment practices.

Many socially conscious investors are going beyond SRI to seek out investments that prioritize a positive impact, sparking a rise in ESG and impact investing. This forward-thinking approach was reinforced by the UN Sustainable Development Goals in 2015. These goals, backed by all 193 UN Member States, are an urgent call to solve the world’s most pressing development challenges.


Socially responsible investments now account for over 33% (over $17T) of all assets under professional management in the US, and with increased interest from the millennial generation, that number is only expected to rise. Despite the involvement of large investment firms and funds, socially responsible investments are not exclusive to institutional investors. There’s a range of retail impact investment options that allow anyone to invest ethically and responsibly.

The history of socially responsible investing shows that what’s old is new again. We can see that this growing movement shows no signs of stopping, making for an even larger impact as more investors get involved.
