ESG Investing

ESG investing has seen significant growth in recent years. Individuals are increasingly using ESG criteria to evaluate trading opportunities. In this article, we break down key themes and definitions and offer a complete guide to ESG investing in the UK, from stocks to watch and funds to explore.

What Is ESG Investing?

The simple definition is that ESG trading refers to sustainable investments that balance financial returns with long-term impacts on society and the environment. ESG criteria consider non-financial performance indicators, such as the carbon footprint of a company, how ethical its supply chain is, and the diversity of its management team.

Note, ESG investing terminology can easily be confused with subtle variations:

  • Impact Investing – Using capital investments to create a positive outcome
  • Ethical Investing – Channelling equity into companies whose practises and values match your personal beliefs
  • Socially Responsible Investing (SRI) – Selecting investments based on ethical criteria instead of financial data

The key ESG principles are explained below.


Put simply, how environmentally conscious are the operations and outputs of a company? Criteria could include an organisation’s renewable energy use, pollution and waste levels, its drain on natural resources, and its landscape protection.

The risk management practices and strategies a company uses in respect of its environmental impact can be analysed to assign an ESG rating. For example, are global guidelines and regulations being followed for commodities trading to reduce carbon emissions? Previous corporation greenwashing trading claims in the news may also be of interest.


Social factors consider relationship trends between a company and the communities in which it operates. Examples could include employee education support, a robust charitable wealth management framework, healthcare benefits, or local community impact initiatives. When ESG investing, social ratings can also take into account the diversity of a workforce and its supply chain concerning modern slavery.

ESG investors should keep an eye on newsletter articles and media reports relating to a company’s impact on the people it operates around. Annual rankings and lists are also published by the likes of the FT and LinkedIn.


Governance relates to how robust and ethical an organisation’s management framework is. Factors to consider include performance transparency, the data accuracy of reports and statistics, the diversity of boards, and compliance with tax responsibilities.

Many companies now publish details on their governance structure in corporate sustainability white papers and annual statements.

History Of ESG

ESG investing is not a new concept. Reviews and articles indicate the simple approach has been adopted as far back as the 1800s. More recently, the United Nations launched investment principles in 2006, encouraging the incorporation of ESG criteria into traditional financial markets. Many globally recognised institutions with varying market sizes became signatories including across Europe and Asia. Aligned companies include Zurich, Aviva, Barclays, Blackrock, Bloomberg, Morningstar, and UBS.

History of ESG

Today, the rise in ESG investing continues to boom. The value of assets sitting under responsible trading strategies stood at $22.9 trillion in 2016. And figures suggest the volume and demand for ESG-friendly stocks and funds are likely to continue as investors increasingly look for trading opportunities that allow them to support companies behaving ethically.

Why Invest In ESG Stocks?

ESG trading is gaining traction as the green agenda and responsible investing move front of mind. Moreover, articles from the Economist, Wall Street Journal, and the New York Times suggest this trend strengthened during the COVID 19 pandemic. People are increasingly asking questions of stakeholders when it comes to social issues like employee health and the safety of working conditions.

Investing data reports from the likes of Google Scholar and Harvard all support the notion that ESG-focused companies are capable of producing superior financial results vs corporations uninterested in their social and environmental impact. ESG-conscious companies also tend to experience reduced price volatility. This is eroding the traditional view that responsible investing doesn’t generate profits.

Another advantage of ESG trading is portfolio risk management. Investing in sustainable energy stocks, for example, is a good way to diversify your portfolio and spread risk across sectors. Electric vehicles and Tesla shares are a popular example of how trading in ESG-friendly stocks can yield impressive returns.

How To Evaluate ESG Stocks

As regulators and markets grapple to introduce standardised ESG metrics, there are multiple ratings agencies and analysts passing judgement on the suitability of stocks and funds. Popular providers of ESG investor ratings include Fidelity and Morningstar.

Company facts, previous events, market research, and employee insights are used to paint investors a picture of how successfully or unsuccessfully, a stock is at meeting ESG objectives. Machine learning algorithms also sift through company credentials, financial reporting, and published quotes to understand whether greenwashing may cause firms to underperform vs those with true commitments to ESG criteria.

ESG investing strategies

As you start ESG investing, carefully review a company’s public announcements and track record of enhancing the green agenda, such as reducing international travel for business, where necessary, or improving the diversity of its boards. A negative screening investing strategy can also be used – excluding companies involved in certain industries, such as tobacco, alcohol, and pornography.
