What is ESG?

ESG is an increasingly important investment strategy where the investor only puts money into companies that perform well on environmental, social, and governance issues. It has grown more popular in recent years, particularly with younger investors who put money into what they value.

Socially conscious investors can screen whether or not a company qualifies for ESG investing by using guides that rates them against each component. This type of investing is also referred to as sustainable investing, responsible investing, impact investing, and/or socially responsible investing. 

Demand for ESG investing particularly rose during the pandemic in 2020. Research shows that investors held $17 trillion in assets that employed ESG criteria at the beginning of 2020 – a significant increase from $12 trillion in 2018.

  • Publishing updated reports on carbon and environmental sustainability
  • Reducing energy usage
  • Treating animals ethically
  • Lowering greenhouse gas emissions

  • Donating a proportion of its revenues to philanthropic causes
  • Paying fair wages
  • Encouraging employees to volunteer in their local community
  • Demonstrating health and safety concerns for employees in the workspace
