Palm oil is one of the world's most widely used vegetable oils. It appears in cooking oils, packaged foods, cosmetics, cleaning products, and certain biofuel applications. Its versatility, relatively low production costs, and high oil yield have made it an important commodity in global agriculture.
However, the expansion of palm oil production has also raised major environmental concerns. In some regions, plantations have replaced tropical forests, fragmented wildlife habitats, and contributed to greenhouse gas emissions. The drainage of carbon-rich peatlands and the use of fire for land clearing can create additional environmental damage.
These impacts have made palm oil a central issue in debates about deforestation, biodiversity conservation, and sustainable agriculture.
The picture is not entirely one-sided. Palm oil is economically important to producing countries and supports the livelihoods of plantation workers, smallholders, processors, and other participants in the supply chain. Oil palm also produces more oil per unit of land than many other major oil crops, which complicates the idea that simply replacing it with another vegetable oil would solve the environmental problem.
The International Union for Conservation of Nature (IUCN) has highlighted this trade-off: palm oil production can harm biodiversity when it replaces natural habitats, but substituting other oil crops may require more agricultural land. Source: IUCN, Palm Oil and Biodiversity.
Understanding palm oil and land use therefore requires a broader question: how can societies meet demand for vegetable oil without continuing to destroy ecologically valuable landscapes?

What Is Palm Oil?
Palm oil is a vegetable oil extracted from the fruit of the oil palm tree, primarily Elaeis guineensis, a species native to West Africa.
The fruit produces two commercially important oils. Palm oil comes from the fleshy part of the fruit, while palm kernel oil is extracted from the seed inside it. Although they come from the same fruit, the oils have different compositions and uses.
Palm oil is used in a wide range of products, including:
Cooking oil and margarine.
Packaged foods and processed ingredients.
Soaps, detergents, and personal-care products.
Cosmetics and household products.
Certain biofuels and industrial applications.
Its versatility makes it difficult to remove from global supply chains without considering what might replace it.
Oil palm grows well in humid tropical climates. As demand for vegetable oils has increased, commercial cultivation has expanded across parts of Southeast Asia, Africa, and Latin America.
Indonesia and Malaysia have become particularly important producers. However, oil palm is not exclusive to these countries, and future production may expand in other tropical regions where land, climate, infrastructure, and investment allow cultivation.
The environmental consequences depend greatly on where plantations are established and how they are managed.
Why Is Palm Oil So Important to Global Agriculture?
Palm oil has become commercially successful partly because oil palm is highly productive.
Compared with many other oil crops, oil palm can produce a relatively large quantity of oil from a given area of land. This helps explain why palm oil supplies a substantial share of the world's vegetable oil while occupying a smaller share of the land used to grow oil crops.
According to the IUCN's assessment, oil palm can produce several times more oil per hectare than alternatives such as soybean, rapeseed, or sunflower, although exact comparisons depend on yields and production conditions. Source: IUCN, Oil Palm and Biodiversity.
This productivity creates both economic advantages and environmental complications.
On the economic side, high yields can make palm oil relatively affordable and support large agricultural industries. On the environmental side, the profitability of oil palm can encourage expansion into new areas, including landscapes that should remain protected.
The important distinction is between producing more oil from suitable existing agricultural land and expanding plantations into natural ecosystems.
Higher productivity does not automatically guarantee sustainability. The location of production, land ownership, labor conditions, and environmental safeguards remain crucial.
Palm Oil and Land Use: What Do the Numbers Tell Us?
The scale of oil palm cultivation helps explain why land use is central to the environmental debate.
Data compiled by Our World in Data from the Food and Agriculture Organization of the United Nations (FAO) show that the global harvested area for oil palm fruit reached approximately 29 million hectares in 2024. Indonesia accounted for approximately 14.3 million hectares, while Malaysia accounted for about 5.1 million hectares. These figures describe harvested area under the dataset's methodology, not a direct measurement of every hectare planted or all land affected by the industry. Source: Our World in Data, Land Used for Palm Oil Production.
These figures illustrate the concentration of production in Southeast Asia and the substantial land footprint of the industry.
However, the total area used for oil palm does not reveal the full environmental story. Two plantations of equal size may have very different impacts depending on what occupied the land before cultivation.
A plantation established on previously cleared, degraded agricultural land may have a different environmental footprint from one that replaces primary rainforest or drains a peatland.
To assess palm oil's environmental impact accurately, it is necessary to consider both the amount of land used and the ecological value of the land before conversion.
How Palm Oil Production Can Drive Deforestation
One of the most serious environmental concerns associated with palm oil is the conversion of natural forests into plantations.
Tropical forests contain complex ecosystems with diverse plants, animals, and microorganisms. They also store carbon in living vegetation and soils. Clearing these forests can therefore cause several environmental impacts simultaneously.
Forest conversion for plantations
When natural forest is cleared to establish oil palm plantations, wildlife loses habitat and the landscape becomes more fragmented.
The effects can extend beyond the plantation itself. Roads and other infrastructure may provide access to surrounding forests, making additional land conversion easier.
The resulting environmental damage depends on the forest type, the amount cleared, the condition of nearby habitats, and whether the landscape can recover.
Not every oil palm plantation has been established on recently cleared forest. Some occupy land that was already used for agriculture or other purposes. This is why the history of a plantation matters when evaluating its environmental impact.
Why forest loss matters beyond tree cover
Forests perform functions that are not easily reproduced by a commercial plantation.
Natural forests contain diverse vegetation structures, complex food webs, and ecological relationships that develop over long periods. Oil palm plantations can provide some habitat and environmental functions, but they generally do not support the same biodiversity as intact natural tropical forests.
Planting trees after clearing a forest does not automatically replace the original ecosystem.
Effective land-use policies must therefore distinguish between restoring degraded land, managing existing plantations, and converting remaining natural forests.
Palm oil is not the only driver of deforestation
Palm oil is an important driver of forest conversion in some regions, but it is not responsible for all deforestation.
Other drivers include cattle ranching, soybean cultivation, timber extraction, mining, infrastructure development, and small-scale agriculture. Their relative importance varies between countries and landscapes.
Focusing exclusively on palm oil can obscure the broader economic and political factors behind land-use change.
A more effective approach addresses deforestation across agricultural commodities and other land-intensive industries, with safeguards that reflect the environmental sensitivity of each region.
Palm Oil, Biodiversity, and Wildlife
The relationship between palm oil and biodiversity is especially important because oil palm grows in tropical regions that often contain exceptionally rich wildlife habitats.
When natural habitats are converted into plantations, species may lose food sources, nesting sites, breeding areas, and the ability to move between forest patches.
Habitat fragmentation
A large, connected forest allows animals to move through the landscape in search of food, mates, and suitable habitat.
When forests are divided into smaller fragments by plantations, roads, and other development, wildlife populations can become isolated. Smaller populations may be more vulnerable to disease, environmental disturbances, and the loss of genetic diversity.
Some species can adapt to modified landscapes, but others depend on large areas of relatively undisturbed habitat.
Threats to endangered species
In parts of Southeast Asia, forest conversion has contributed to habitat loss for species such as orangutans, tigers, and other wildlife.
The impact is not limited to the direct removal of trees. Human-wildlife conflict may increase when animals enter plantations or settlements after losing access to their original habitat.
Wildlife may also face additional pressures from roads, hunting, and other activities associated with expanding access to forest landscapes.
Protecting biodiversity requires more than setting aside small patches of vegetation within plantations. It also requires conserving sufficiently large, connected areas of natural habitat and managing the surrounding landscape responsibly.
Why plantation trees are not a substitute for natural forests
An oil palm plantation is a productive agricultural system, but it is not ecologically equivalent to a natural tropical forest.
Natural forests contain many plant species and different vegetation layers, creating habitats for a broad range of organisms. Commercial plantations typically contain a more uniform crop structure designed for efficient harvesting.
This difference matters because biodiversity depends on the variety and condition of habitats, not simply on whether a landscape contains green vegetation.
For conservation, the priority should be to prevent the conversion of high-value natural habitats and improve the management of land already under agricultural production.
Palm Oil, Peatlands, and Climate Change
The environmental impact of palm oil production can become particularly severe when plantations are established on peatlands.
Peatlands are ecosystems where partially decomposed organic material accumulates over long periods under waterlogged conditions. Tropical peatlands can store substantial amounts of carbon in their soils.
When peatlands are drained for agriculture, the exposure of organic material to oxygen accelerates decomposition and releases carbon dioxide. Drained peat can also become more vulnerable to fire.
Why peatland drainage matters
Establishing plantations on drained peatland can produce emissions that continue long after the initial land conversion.
Even when vegetation is growing on the surface, the underlying peat may continue to lose carbon as drainage changes the soil environment.
This creates an important distinction between the emissions associated with clearing vegetation and the longer-term emissions caused by changes in peatland hydrology.
Protecting intact peatlands and restoring degraded peatland water conditions can therefore deliver benefits beyond the plantation boundary.
Peat fires and regional haze
Dry peat can burn below the surface, making peat fires difficult to detect and extinguish completely.
These fires may release large quantities of smoke and fine particulate matter, contributing to poor air quality across broad areas. Their effects can extend into nearby cities and across national borders, depending on wind and atmospheric conditions.
Peat fires are influenced by several factors, including drainage, weather, ignition sources, and land management. They should not be attributed to palm oil alone, although oil palm expansion and other agricultural activities can be part of the wider land-use context.
For a broader explanation of fire causes and impacts, see Wildfires Around the World: Causes and Impacts. The Indonesia-specific causes and haze impacts belong in the geographic subcluster under Wildfires.
The Economic and Social Importance of Palm Oil
Environmental concerns should not obscure the economic role of palm oil.
The industry provides employment across cultivation, harvesting, processing, transportation, trading, and manufacturing. It can also generate income for smallholders who grow oil palm on relatively small plots of land.
In major producing countries, palm oil contributes to export earnings, rural economic activity, and the development of supporting infrastructure.
For some farming households, oil palm offers a valuable source of income. For workers and local businesses, the industry may provide opportunities that are limited in other sectors.
However, these benefits are not distributed equally.
The economic position of smallholders can depend on access to finance, land tenure, planting materials, agricultural advice, processing facilities, and reliable markets. Workers may face concerns related to wages, working conditions, and labor protections. Communities may also experience conflicts when plantation development affects customary land or access to forests.
Sustainable palm oil therefore requires attention to social conditions as well as environmental performance.
Land-use decisions should consider the rights of local communities, transparent consultation, fair compensation where appropriate, and mechanisms for resolving disputes.
Can Palm Oil Be Produced More Sustainably?
Palm oil's high productivity means that improving the way it is produced can be an important part of reducing its environmental footprint.
The objective is not simply to increase output. It is to produce palm oil while protecting forests, peatlands, biodiversity, workers, and communities.
1. Prevent deforestation
One of the most important measures is to prevent the establishment of plantations through the conversion of high-value natural forests.
This requires clear land-use planning, credible environmental assessments, effective enforcement, and monitoring of land conversion.
Companies can strengthen their policies by tracing supplies to plantations and ensuring that new production does not depend on clearing protected or otherwise high-value ecosystems.
2. Protect and restore peatlands
Avoiding new drainage of intact peatlands can prevent long-term emissions and reduce the risk of severe peat fires.
In degraded peat landscapes, restoration may involve raising water levels, blocking drainage channels where appropriate, restoring vegetation, and working with communities to reduce fire risk.
Peatland restoration is technically complex and must be adapted to local hydrology and land-use needs. It is not simply a matter of planting trees.
3. Improve yields on existing plantations
Increasing productivity on suitable existing agricultural land can help reduce pressure to expand into natural ecosystems.
Possible measures include improving planting materials, maintaining soil health, managing pests responsibly, and providing farmers with appropriate technical support.
However, yield improvements must be combined with effective land-use safeguards. If greater profitability encourages additional expansion, productivity gains alone may not reduce deforestation.
4. Strengthen smallholder support
Smallholders may face financial and technical barriers to adopting more sustainable practices.
Access to training, better planting materials, credit, transparent purchasing arrangements, and credible certification can help farmers improve productivity and meet environmental requirements.
Policies should also avoid imposing compliance costs that exclude smaller producers from markets without offering practical support.
A sustainable supply chain needs to be environmentally responsible and economically accessible to the people who produce the crop.
5. Improve supply-chain traceability
Palm oil passes through multiple stages, from plantations and mills to refineries, manufacturers, and retailers.
Without traceability, companies may struggle to identify where their raw materials originated or whether they are associated with deforestation.
Satellite monitoring, plantation records, independent audits, and transparent supplier information can improve accountability.
Traceability is not sufficient by itself, however. Data must be accurate, risks must be investigated, and companies must respond when violations are identified.
6. Apply credible sustainability standards
Certification systems can help establish environmental and social requirements for palm oil production.
The Roundtable on Sustainable Palm Oil (RSPO), for example, provides standards intended to promote more sustainable palm oil production and supply chains. Its requirements address issues such as forest protection, biodiversity, and social responsibility.
Certification can provide useful tools for improving practices, but its effectiveness depends on implementation, independent assessment, transparency, and follow-up when non-compliance occurs.
Consumers and businesses should therefore look beyond a label and consider the credibility of the standard, the scope of certification, and the evidence supporting sustainability claims.
Is Boycotting Palm Oil the Best Solution?
Calls to boycott palm oil often emerge from concerns about deforestation, wildlife loss, and labor conditions. These concerns are legitimate, but a blanket boycott may not produce the best environmental outcome.
Palm oil is highly productive compared with many other vegetable oils. Replacing it with alternatives could require more agricultural land to produce a comparable quantity of oil, potentially shifting environmental pressure to other ecosystems.
The IUCN has warned that replacing palm oil does not automatically eliminate biodiversity loss because alternative oil crops also require land and can affect natural habitats. Source: IUCN, Why Saying No to Palm Oil May Shift Biodiversity Loss.
This does not mean consumers should ignore harmful production practices or that palm oil should be exempt from environmental scrutiny.
A more targeted approach focuses on reducing unnecessary demand, preventing deforestation, protecting peatlands, improving traceability, and supporting responsible production.
For certain non-food uses, policymakers may also evaluate whether the environmental benefits justify the land and resource requirements involved.
The broader principle is that environmental policy should compare the full impacts of alternatives rather than assuming that replacing one commodity will automatically solve the problem.
What Can Consumers and Businesses Do?
Consumers can help by learning where palm oil is used, reducing avoidable waste, and supporting credible efforts to improve production standards.
However, identifying palm oil on product labels can be difficult because ingredients may be listed under different names, and labeling requirements vary by market.
Businesses have a more direct responsibility to examine their supply chains and ensure that sustainability commitments are supported by evidence.
Practical measures include:
Mapping suppliers and improving traceability.
Requiring credible environmental and labor safeguards.
Avoiding sourcing linked to illegal forest conversion.
Monitoring high-risk production regions.
Supporting smallholders in meeting sustainability standards.
Publishing clear progress reports and responding to verified violations.
Governments can contribute by enforcing land-use laws, protecting high-value ecosystems, clarifying land rights, and requiring transparent environmental reporting.
No single actor can address the full challenge. Sustainable palm oil depends on coordinated action across producing countries, importing markets, companies, farmers, and communities.
Conclusion: Better Land Use Is More Important Than Simple Substitution
Palm oil illustrates the difficult choices involved in balancing global food demand, economic development, and environmental protection.
Its high productivity makes it an important source of vegetable oil, while its expansion into natural forests and peatlands has contributed to habitat loss, biodiversity decline, and greenhouse gas emissions in some regions.
The environmental impact of palm oil is not determined by the crop alone. It depends on where it is grown, how land is acquired and managed, whether natural ecosystems are protected, and how the supply chain is governed.
Simply replacing palm oil with another vegetable oil may shift environmental pressure rather than eliminate it. Conversely, the industry's economic importance does not justify clearing ecologically valuable forests or ignoring the rights of affected communities.
The most effective path combines protection of natural habitats, responsible production on existing agricultural land, peatland conservation, stronger supply-chain traceability, and credible accountability.
Palm oil is therefore not just a debate about one agricultural commodity. It is a broader test of whether global food and consumer industries can meet demand without treating natural ecosystems as expendable.
Better land-use decisions can help reduce the environmental cost of palm oil while protecting the livelihoods and resources that future generations will also depend on.
