Despite a barrage of Republican attacks, lackluster returns and diminishing client interest in the US, BlackRock Inc. has been quietly expanding its dominance in ESG investing.

The world’s largest asset manager has posted net ESG inflows every quarter for the past two years, a period that marks one of the toughest ever in the two-decade history of environmental, social and governance investing.

In all, BlackRock’s ESG-related assets under management swelled 53% from the beginning of 2022 through the end of last year, according to data provided by Morningstar Direct. Over the same period, the wider ESG fund market grew only about 8%. The money manager now oversees roughly $320 billion of ESG funds, more than any other investment firm in Europe, the US or globally.

BlackRock declined to comment on the figures, which are based on Morningstar’s own assessment of sustainability metrics and exclude excludes money market, feeder and funds of funds. According to its websites, BlackRock manages $665 billion via its sustainable investing platform, and integrates what it considers to be financially material ESG data into firm-wide investment processes.

“BlackRock has been the biggest contributor of inflows into ESG funds over the past five years, including the past couple of years,” said Hortense Bioy, Morningstar’s global director of sustainability research. And that’s “despite the ESG backlash in the US.”

That backlash has been increasingly aggressive, as the Republican Party seeks to characterize ESG as woke, anti-capitalist and even anti-American. BlackRock has often found itself at the receiving end of ESG-related outrage, prompting Chief Executive Officer Larry Fink to declare the label too “weaponized” to use. That followed warnings in which he said the debate around ESG had become “ugly” and “personal.”

“We can expect the ESG backlash in the US to continue until the election,” Bioy said. “And perhaps also beyond, depending on the outcome of the election.”

To complicate the narrative for ESG’s proponents, the macroeconomic forces that have prevailed since the end of the pandemic, including high interest rates, have proved a poisonous cocktail for many of the green stocks that traditionally fill ESG portfolios. Last year, the S&P Global Clean Energy Index slumped 20%, while the S&P 500 rose 26%, including reinvested dividends.

But ESG is more than just wind and solar. The three BlackRock funds (tickers: ACSEUX3@LN, EEDS@LN and ACWEIXG@LN) that saw the biggest asset growth last year, according to Morningstar, all counted Microsoft Corp. and Apple Inc. as their two biggest holdings.

In the US, Morningstar estimated in September that the most popular ESG strategy is called climate transition, which is supposed to dedicate capital to making not-so-green assets greener. The climate-transition fund that attracted the biggest inflow is BlackRock’s iShares Climate Conscious & Transition MSCI USA ETF (USCL@US), whose top holdings are Nvidia, Amazon.com and Microsoft.

The wider ESG fund market, meanwhile, suffered a stinging blow in the final three months of 2023 with the first-ever net client outflows. The retreat was led by the US, where redemptions were too big for European inflows to offset.

As the global fund market lost $2.5 billion of ESG client cash last quarter, BlackRock had net inflows of $4.7 billion, led by its European business and index-tracking strategies, according to Morningstar. BlackRock saw $5.6 billion in new money flow into passive ESG strategies, more than making up for the roughly $900 million that flowed out of active strategies, net, Morningstar said.

For ESG globally, index-tracking investing is starting to supplant active management. Even in Europe, the biggest market for ESG investing by far, the trend was striking. Passive ESG funds brought in $21.3 billion last quarter, while clients in actively managed ESG funds withdrew almost $18 billion, according to Morningstar.

The development is all the more noteworthy because ESG was always supposed to be uniquely suited to active management, due to the extra layers of analysis thought to be required to screen for things like climate and biodiversity risk.

Bioy said the latest flow figures show the “disappointing reality” that managers pushing active ESG strategies “failed” to prove to clients that they should be entrusted with their money, despite sitting in a “corner of the market where it’s easier for them to prove their worth.”

For now, active ESG strategies continue to outnumber index-tracking products in both Europe and the US. But the latest flow data suggests that dynamic may shift. Morningstar notes that 85% of BlackRock’s ESG fund products are now in passive strategies. And Bioy also points out that BlackRock’s growth in ESG has coincided with a decline in the number of ESG resolutions it supports.

In Europe, meanwhile, competitors are taking note. Amundi SA, Europe’s largest investment manager and the world’s No. 3 in ESG, targets having 40% of its index-tracking ETFs become ESG products in 2025. At the end of last year, that ratio was 33%.

In all, the “disappointing” results produced by active ESG managers have “compelled investors to shift to passive, low-cost” strategies, according to Morningstar.
