The Palm Oil Industry's Deforestation Cover-Up: Documented Versus Denied

In the dry season of 1997, and again far worse in 2015, the sky over Singapore and much of maritime Southeast Asia turned the colour of weak tea. Schools closed. Aircraft were grounded. The “haze,” as the region calls it with grim understatement, was smoke — much of it from fires set to clear peatland and rainforest in Sumatra and Indonesian Borneo, largely to plant oil palm. A study published in 2016 by researchers at Harvard and Columbia estimated that the 2015 fires alone may have caused on the order of a hundred thousand premature deaths across Indonesia, Malaysia and Singapore. The fires were not an act of God. They were a predictable by-product of the fastest agricultural expansion on the planet, growing a crop that ended up in roughly half the packaged products on a Western supermarket shelf — in biscuits, soap, instant noodles, lipstick, margarine, ice cream and, for a while, the biodiesel that was supposed to be saving the climate. The industry had a certification scheme that promised much of this oil was grown sustainably. The distance between that promise and the satellite images is the subject here.

The crop that ate the forest

Begin with the scale, because it is what makes the deception possible. Oil palm, Elaeis guineensis, is native to West Africa but grows most productively in the wet lowland tropics of Southeast Asia. It is astonishingly efficient — per hectare it yields far more oil than soy, rapeseed or sunflower, which is precisely why it conquered global kitchens and factories. World production of palm oil rose from a few million tonnes in the 1970s to well over seventy million tonnes a year in the 2020s. Indonesia and Malaysia together account for the great majority of it.

That land had to come from somewhere, and in the crucial decades it came overwhelmingly from tropical forest and carbon-rich peat swamp. The environmental cost is documented in a way that leaves little room for argument, because it is visible from orbit. Satellite analyses — from the University of Maryland’s Global Forest Watch, among others — tracked the loss of primary forest across Sumatra and Borneo year by year. Studies in journals including Nature Climate Change linked a substantial share of that clearance directly to oil-palm expansion. And the habitat destroyed was not generic woodland. It was the last strongholds of the Sumatran and Bornean orangutan, the Sumatran tiger, the pygmy elephant — species pushed toward extinction as their forest was replaced by monoculture rows.

Peat made it worse in a way the public rarely grasps. Tropical peatlands are waterlogged soils holding centuries of undecayed vegetation, and thus enormous quantities of carbon. To plant palm on them, companies drained and often burned them. Drained peat oxidises and can smoulder underground for months, releasing carbon dioxide long after the visible flames are out. For a period in 2015, Indonesia’s daily greenhouse-gas emissions from these fires reportedly exceeded those of the entire United States economy. A crop marketed, at one point, as a green biofuel was helping to torch one of the planet’s largest natural carbon stores.

The promise on the label

None of this was secret in the sense of being hidden. The cover-up in the palm-oil story is subtler and, in some ways, more modern than the sealed-filing-cabinet secrecy of the tobacco industry’s hidden research. Here the mechanism of concealment was a reassurance — a certification label that let everyone in the supply chain, from grower to shopper, believe the problem was being handled.

In 2004, under pressure from environmental groups and worried buyers, the industry and several NGOs founded the Roundtable on Sustainable Palm Oil, the RSPO. It set standards — no clearing of primary forest or “high conservation value” areas, no new planting on deep peat, respect for the land rights of local communities — and certified companies and plantations that complied. Products could then carry a “sustainable palm oil” claim. Major consumer-goods multinationals — Unilever, Nestlé, Mondelēz and others — pledged to source only certified sustainable palm oil, often by a target year such as 2015 or 2020. On paper, the market was cleaning itself up.

The gap between the label and the ground is where the documentation becomes damning. Investigations by Greenpeace, the Environmental Investigation Agency and the Wall Street Journal, among others, repeatedly found RSPO-certified companies, or their suppliers and subsidiaries, linked to ongoing deforestation, peatland burning and land-rights abuses. The RSPO’s own complaints panel upheld cases against member companies. A recurring finding was structural: a large grower might hold certification for one plantation while a sister company or supplier, sometimes with overlapping ownership, cleared forest elsewhere, and the certified oil and the deforestation oil flowed into the same opaque global supply chain, becoming impossible to tell apart by the time they reached a factory. “Sustainable” palm oil and forest-destroying palm oil were, in practice, often the same barrels.

Where knowing and denying diverged

The phrase “documented versus denied” is the exact hinge of this case, and it deserves to be stated plainly. The companies most implicated did not, on the whole, dispute that deforestation was occurring in the abstract. What they denied was their own specific responsibility for it — and the internal record repeatedly showed they knew more than they admitted.

The clearest illustrations came from leaked and disclosed documents. Wilmar International, at one point the world’s largest palm-oil trader handling a large fraction of global supply, adopted a landmark “No Deforestation, No Peat, No Exploitation” policy in 2013 after sustained campaigning. Yet subsequent investigations by Greenpeace and others alleged that suppliers within its vast network continued clearing forest, and that the company’s own monitoring had flagged problems that were slow to translate into cut-off suppliers. In 2018, Greenpeace’s report Final Countdown used the industry’s own supplier data to link household-name brands, through Wilmar and other traders, to thousands of hectares of recent deforestation — using, in other words, the companies’ published information to show that their public commitments were not being met on the ground.

Nestlé provides the most public single episode. In 2010, Greenpeace released a study, and a deliberately shocking spoof advertisement, connecting the palm oil in Kit Kat bars to the destruction of orangutan habitat by an Indonesian supplier, Sinar Mas. Nestlé’s first instinct was denial and damage control — it tried to have the campaign video taken down, which only amplified it. Within weeks, faced with the evidence and a viral consumer backlash, the company cut ties with the supplier and committed to a no-deforestation policy. The documents in that case did not have to be leaked from a safe. They were satellite images and supply-chain records that the company could have consulted itself, and in some form had.

The smallholder complication is part of what kept the system opaque, and it deserves honest acknowledgement. Not all palm oil comes from vast corporate estates. In Indonesia and Malaysia, millions of people — independent smallholders farming a few hectares each — grow oil palm as their main cash crop, selling fruit to mills they do not own. Their forest clearance is real, but it is scattered, hard to certify, and driven by ordinary rural poverty rather than boardroom strategy. Big traders learned to point at this diffuse smallholder layer as the source of “leakage,” a way of conceding that deforestation happened while locating the blame conveniently below their own supply chain. The truth was that the certified estates and the uncertifiable smallholders and the deliberately clearing subsidiaries all fed the same mills and the same tankers, and the industry’s monitoring was often precise enough to know this and structured so as not to have to act on it.

That is the texture of the palm-oil cover-up. It was rarely a bald lie that deforestation did not happen. It was a system engineered to preserve plausible deniability across a supply chain deliberately kept complex enough that no single company had to own the fire — while a green label reassured the public that someone, somewhere, had it under control.

The shopper who wanted to be told it was fine

Follow this story back far enough and it stops being only about corporations and becomes about the rest of us, which is where it starts to resemble a piece of modern folklore about our own good intentions.

The demand for palm oil is not a corporate invention. It is in half the supermarket because it is cheap, versatile, stable at room temperature and free of the trans fats that an earlier health panic drove food companies to abandon — a switch that, in one of history’s dark jokes, made the margarine and hydrogenated-fat scares partly responsible for the surge in tropical-oil demand. We wanted cheap biscuits and soft spreadable spreads and lathering shampoo, and we did not want to think about where the fat came from. The certified-sustainable label existed because we wanted, badly, to be told that we could keep buying all of it without the orangutan on our conscience.

That is the human need the label served, and it is why the scheme could underperform for so long without collapsing. A certification is a device for outsourcing your conscience. It lets a busy shopper transfer the moral labour of investigation to a logo, and get on with the shopping. The RSPO was not purely cynical — it did raise standards, it did give campaigners leverage, and genuinely deforestation-free supply chains do now exist because of pressure it helped create. But its most reliable product, for years, was peace of mind, sold to consumers who preferred the reassurance to the reckoning. The companies understood this appetite perfectly, because they shared it. Everyone in the chain, right down to the person putting the biscuits in the trolley, had a stake in believing the label meant what it said.

What the haze actually taught

It would be neat to end by weighing up whether palm oil is good or bad, but that framing is exactly the trap the whole story sets. Palm oil is a genuinely efficient crop; boycotting it entirely can shift demand to other oils that need far more land, doing greater damage elsewhere — the honest environmental answer is complicated and unsatisfying in the same way the DDT and malaria debate is complicated. The interesting thing the palm-oil case reveals is not a verdict on a vegetable oil. It is how a modern cover-up actually works when the crime is too big and too visible to hide.

Twenty-first-century concealment does not always look like a locked drawer. Sometimes it looks like transparency itself — a roundtable, a standard, a certificate, an annual sustainability report thick with photographs of smiling smallholders. The deforestation was never really hidden; anyone with satellite access could see it. What was hidden was responsibility, dissolved into a supply chain complex enough that no one had to hold it, and papered over with a reassurance that let the rest of us look away in good conscience. The smoke that closed Singapore’s airports was the system telling the truth about itself, in the one language — a sky full of ash — that no certificate could soften. The uncomfortable lesson is that when we are offered a clean way to keep consuming something we would rather not examine, most of us will take the label and ask no further questions, and a great deal of the modern economy is built on knowing precisely that about us.
