The Generational Disconnect: Why Gen Z Heirs Want to Divest from Fossil Fuels Against Their Parents’ Wishes

There’s a particular tension that tends to surface at family gatherings in certain wealthy households — not over politics, exactly, but close enough. It’s the kind of quiet, loaded disagreement that nobody quite names out loud but everyone feels. The older generation built something. The younger one has decided, with increasing conviction, that what was built is the problem.

The numbers bear this out in ways that are hard to dismiss. A survey conducted by CMC Invest, polling more than 2,000 investors each holding at least £10,000 in investable assets, found that 79% of Gen Z investors now examine ESG credentials — environmental, social, governance standards — before committing money anywhere. It’s not a position on the periphery.

It’s an instinct shared by all generations. Meanwhile, 79% of the so-called silent generation, investors aged 77 and above, said they don’t look at ESG criteria at all. The gap between those two numbers tells you almost everything about where this conflict is headed.

The Rockefeller story is perhaps the most vivid illustration of how this plays out at scale. The heirs to one of the great American oil fortunes — built by John D. Rockefeller through Standard Oil, a company that once controlled the world’s largest refineries and eventually spawned Exxon, Amoco, and Chevron — announced their divestment from fossil fuels as part of a $50 billion global campaign.

Stephen Heintz, president of the Rockefeller Brothers Fund, framed it with a kind of pragmatic clarity: the founder himself, as a forward-looking businessman, would likely have made the same call today. It’s possible that argument was meant partly to pre-empt family objection. Whether it worked behind closed doors is another matter.

This generational divide isn’t just ideological, which makes it truly complex. Older investors are maximizing return, especially those who are nearing or have already reached retirement. That’s not greed — that’s logic shaped by a specific life stage. When you have fewer decades ahead of you, the urgency of climate outcomes feels more abstract than the need to preserve capital.

Younger investors, with 40 or 50 years of economic life still in front of them, are making a different calculation entirely. They’re not just worried about the planet in a vague, bumper-sticker sense. They are becoming more and more certain that holding fossil fuels poses real financial risk due to stranded assets, regulatory exposure, and reputational damage.

Archbishop Desmond Tutu once compared fossil fuel divestment to the anti-apartheid movement. It’s a contentious comparison that not everyone agrees with. However, younger inheritors feel that their parents’ generation hasn’t fully considered the convergence of the moral and financial arguments, which are, for once, pointing in the same direction.

On the day of the Rockefeller announcement, the World Council of Churches, which represents about 590 million people in 150 countries, made a divestment. That coalition isn’t fringe. That is the decision made by powerful institutions that continuing is no longer justified.

Universities are slower and perhaps more forthright about how hard it is. Stanford sold its coal holdings. Yale said it would investigate renewables. Harvard, for years, resisted faculty and student pressure entirely — though the Divest-Invest movement’s Beth Dorsey noted, perhaps with quiet confidence, that Harvard said no before it said yes to anti-apartheid divestment too. It’s still unclear whether the holdouts are making a principled financial argument or simply avoiding the discomfort of admitting the ground has shifted.

Unexpectedly, the CMC Invest survey also shows that younger investors aren’t waiting for things to get better. Some 58% of Gen Z respondents said they invested more money through 2023, even as the cost of living crisis squeezed household budgets across the UK.

They’re not docile. They’re prioritizing financial independence over traditional retirement goals, moving faster, thinking longer, and — increasingly — refusing to separate where their money goes from what they believe the world should look like.

Watching this unfold across family balance sheets and boardroom tables, it’s hard not to notice that the conflict isn’t really about fossil fuels in isolation. It concerns two essentially distinct ways of relating to time. One generation amassed. The other inherited — and is now asking whether the inheritance is really worth keeping in its current form. Quietly but with increasing conviction, they are coming to the conclusion that the answer is no. Additionally, most of their parents aren’t yet prepared to hear it.
