Palm oil is controversial because its production drives tropical deforestation, threatens endangered species, and has been linked to forced labor and child labor, yet it remains in roughly half of all packaged products on supermarket shelves. It is the world’s most widely used vegetable oil, with global production exceeding 77 million metric tons per year. The backlash against it touches environmental destruction, climate change, human rights abuses, and unresolved questions about its health effects.
Deforestation and Wildlife Loss
Oil palm trees thrive in the same tropical belt that houses some of the planet’s most biodiverse rainforests. Indonesia and Malaysia produce the vast majority of the global supply, and expanding plantations have replaced millions of hectares of forest in both countries over the past few decades. This habitat destruction hits hardest for species that depend on intact lowland rainforest, including orangutans, Sumatran tigers, pygmy elephants, and Sumatran rhinos.
Fewer than 80,000 orangutans survive today, according to the World Wildlife Fund, with their habitats under constant threat from continued clearing. Because oil palms are grown as monocultures, a converted plantation supports almost none of the biodiversity a natural forest did. The trees are planted in uniform rows, the understory is stripped, and wildlife corridors disappear. For species like the Bornean orangutan, which need large ranges of connected forest, even small gaps between remaining patches can isolate populations and accelerate decline.
Carbon Emissions From Peatland Conversion
The climate impact of palm oil goes well beyond cutting down trees. In Southeast Asia, large areas of oil palm have been planted on peatlands, which are waterlogged soils that store enormous quantities of carbon built up over thousands of years. To make these areas farmable, companies drain the peat, exposing it to air and triggering decomposition that releases carbon dioxide continuously for years.
Research measuring actual emissions from converted peat swamp forests found staggering numbers. During the initial conversion period, a single hectare released roughly 138 metric tons of CO2 per year. Over the first six years, peat carbon losses averaged about 25 metric tons of CO2 per hectare annually, dropping to around 13 metric tons per hectare in later years as the plantation matured. For context, a typical passenger car emits about 4 to 5 metric tons of CO2 in a year. So one hectare of drained peatland, even in its “lower emission” mature phase, produces the carbon equivalent of two or three cars running nonstop. Drained peat is also highly flammable, contributing to the massive fires that periodically blanket Southeast Asia in haze.
Forced Labor and Child Labor
The human cost of palm oil is less visible but well documented. The U.S. Department of Labor lists palm fruit from Indonesia and Malaysia as a product of both child labor and forced labor. Workers on plantations are frequently subjected to exploitative quota systems that make it nearly impossible to earn a living wage through their own effort alone. When a worker cannot meet the daily quota of harvested fruit bunches, they lose wages or risk losing their job entirely. This pressure pushes unpaid family members, including spouses and children, into the fields.
Children of all ages help their parents pick up loose palm fruits, sometimes for hours after school, and some drop out of school altogether. The work itself is hazardous: harvesting requires long sickles and machetes, workers carry heavy loads in extreme heat, and pesticides are applied without personal protective equipment. Indonesian law classifies these plantation conditions as hazardous work for children. Reports also document excessive work hours, wage theft, and sexual violence on plantations across West Africa and Southeast Asia.
Processing Contaminants and Food Safety
When palm oil is refined at high temperatures to produce the neutral-tasting oil used in processed foods, it generates chemical byproducts that raise food safety concerns. Two groups of compounds, known as 3-MCPD esters and glycidyl esters, form at higher concentrations in refined palm oil than in most other vegetable oils. During digestion, these compounds break down into 3-MCPD and glycidol.
In rodent studies, 3-MCPD caused kidney damage and harm to male reproductive organs, and both 3-MCPD and glycidol caused cancer. The International Agency for Research on Cancer classifies 3-MCPD as a possible human carcinogen and glycidol as a probable one. International food safety bodies have set a provisional maximum tolerable daily intake for 3-MCPD and flagged glycidol exposure as a particular concern for infants and young children, especially through infant formula that contains palm oil as a fat source. These contaminants also appear in other refined vegetable oils like sunflower and soybean oil, but palm oil consistently shows the highest concentrations.
The Saturated Fat Debate
Palm oil is roughly 50% saturated fat, with palmitic acid making up about 44% of its total fatty acid content. That puts it well above oils like olive (about 14% saturated) and soybean (about 15%), which is why nutrition guidelines have traditionally flagged it as a less healthy choice. In many processed foods, palm oil replaced partially hydrogenated oils (trans fats) after those were phased out, trading one nutritional concern for another in the eyes of critics.
The picture is more nuanced than “saturated fat equals bad,” though. A review published in the World Journal of Cardiology found that palm oil consumption does not appear to raise serum cholesterol in the way many people assume. Multiple studies showed that palmitic acid, palm oil’s dominant saturated fat, had effects on blood lipid levels comparable to oleic acid, the monounsaturated fat that gives olive oil its heart-healthy reputation. In clinical crossover trials, substituting olive oil with palm olein produced no significant changes in total cholesterol, LDL, or HDL levels in healthy people. Compared to animal fats like lard, palm oil significantly reduced serum cholesterol. The catch: when measured against oils rich in polyunsaturated fats like soybean or sunflower oil, palm oil did not perform as favorably. So palm oil is not the dietary villain it is sometimes portrayed as, but it is not equivalent to the healthiest available alternatives either.
Why Boycotts Are Complicated
A common response to learning about palm oil’s problems is to avoid it entirely, but this creates its own issues. Oil palm is extraordinarily productive, yielding four to ten times more oil per hectare than alternatives like soybean, sunflower, or rapeseed. Replacing palm oil with another vegetable oil would require far more land, potentially shifting deforestation to other ecosystems rather than preventing it. Palm oil also provides livelihoods for millions of smallholder farmers in developing countries, and a blanket boycott can hurt the very communities that advocacy is meant to protect.
Certification and Regulation
The Roundtable on Sustainable Palm Oil (RSPO) is the most widely recognized certification system, setting standards that prohibit clearing primary forests or high-conservation-value areas. As of 2022, certified sustainable palm oil production exceeded 15 million metric tons, representing about 20% of global crude palm oil output. Another 22% of global production comes from RSPO member companies in the process of certification. That still leaves well over half of the world’s palm oil outside the system entirely, and critics argue that RSPO standards are not strict enough or consistently enforced.
The European Union has taken a more aggressive regulatory approach. The EU Deforestation Regulation, which entered into force in June 2023, requires companies importing palm oil (along with six other commodities) to prove their products were not grown on land deforested after December 31, 2020. Importers must collect geolocation data showing exactly where the palm fruit was produced. Compliance provisions for large companies took effect in late 2024, with small firms given until mid-2025. This regulation is the most ambitious attempt so far to use trade policy to break the link between palm oil and forest destruction, though enforcement remains a significant challenge given the complexity of global supply chains.
The controversy around palm oil persists because there is no clean solution. The oil is efficient to produce, versatile, and economically vital to producing countries. But the environmental damage, carbon emissions, labor abuses, and food safety questions are real and ongoing. Progress through certification and regulation is measurable but slow, covering only a fraction of global production while demand continues to grow.
