Investors across all generations are expressing growing interest in incorporating environmental, social and governance (ESG) factors into their investments, according to a survey by Allianz Life Insurance Company of North America.

The study assessed 1,000 respondents aged 18 years or above.

Millennials are the most interested in ESG investing, says the study that found 64% of millennials citing ESG issues as important in investing.

The trend is also catching up with older generations, with 54% of Gen Xers and 42% of boomers found to be vouching for the same.

Moreover, the bulk of the people surveyed across all generations considered ESG to be a key factor in selecting the companies to do business with.

Millennials were found to be more likely to be interested in learning about different types of ESG information.

Notably, respondents across all generations said that they were unsure about the way to assess whether the companies included in an ESG investment support their causes.

Also, compared to millennials and Gen Xers, more baby boomers said that their ESG investing behavior is driven by the desire to encourage companies to become good corporate citizens.

Allianz Investment Management CIO Todd Hedtke said: “Millennials get a lot of attention for driving ESG investing.

“But when it comes to investing in and doing business with good corporate citizens, there is interest across the board and it’s only going to grow.”
