Mythbusting: No, Palm Oil is NOT in 50% of Supermarket Products

“Absolutely no palm oil, ever!”

A bold claim, often printed proudly across product packaging. But it’s a largely unhelpful statement that stokes consumer fear without offering a clear understanding of the issue. The impacts of palm oil, like those of any vegetable oil, depend far more on how and where it’s produced than on the crop itself.

Fears surrounding palm oil, and the marketing advantages gained by promoting “palm-oil-free” products, are largely driven by media narratives that focus solely on the negative. These one-sided portrayals often ignore the contexts in which palm oil is produced ethically and sustainably, and more importantly, they rarely mention the environmental downsides of the oils that typically replace it.

For example, one frequently cited claim is that palm oil is found in 50% of supermarket products. You may have come across it before; it has become a staple of anti-palm oil campaigns. Big numbers presented in familiar contexts are powerful tools for shaping perception. Think of the widely used image of “6 football fields of forest lost every minute” (ref). But given their potential to influence public opinion and behavior, such statistics should be grounded in solid evidence.

A recent study by myself and a team of scientists, currently under peer-review, explored this particular claim, originally popularized by WWF in 2006. It didn’t take long to discover that the “50%” figure wasn’t backed by research. The parameters were unclear. Did this refer to global supermarkets? Were only packaged goods included? What about household items, fresh produce, or cleaning supplies?

Assessing all products in all supermarkets across the world would be a stretch for a research team of just five. Instead, we selected a random sample of around 2,000 items across three major supermarket chains in the Netherlands, the United Kingdom, and Australia as a practical way to test the claim’s validity.

Our preliminary findings are eye-opening. Palm oil was found in far fewer products than the widely cited 50% claim suggests. In fact, oil crops like maize, rapeseed, and soya appeared in more products than palm (Figure 1). Yet, when was the last time you saw a product proudly declare it was free of rapeseed?

This isn’t to say that palm oil is without its issues or that we should be advocating for its inclusion in everything we consume. Rather, it highlights how palm oil has become an easy scapegoat—singled out by powerful campaigns that have turned it into public enemy number one, while the environmental and social costs of other oils remain largely overlooked.

This study underscores a critical point: the environmental and social impact of any crop—palm oil, soya, maize, or otherwise—is determined not by the crop itself, but by how and where it’s produced. Palm oil isn’t inherently worse than other vegetable oils. In fact, it’s highly land efficient compared to many alternatives. The issue lies in the production practices: deforestation, exploitation, and lack of oversight in some regions are what give palm oil its tarnished name.

Unfortunately, when campaigns present selective or misleading information, they can skew public perception. By vilifying palm oil without context, they may unintentionally endorse its replacements, many of which are just as problematic, if not more so, in different ways. When a product boasts that it’s “palm oil free,” consumers often see that as a moral shortcut. They’re offered a quick and simple choice, and who wouldn’t take the easier option when the narrative feels so clear?

But that clarity is often an illusion. The truth is messy, nuanced, and less marketable. If we truly care about sustainable agriculture and reducing harm, we need to move beyond binary thinking. Consumers must look beyond the label, question the sourcing of all ingredients, and push brands to provide real transparency, whether a product contains palm oil or not.

Sustainability doesn’t come from swapping one logo for another. It comes from understanding systems, challenging simplified narratives, and demanding that all producers of palm, soy, sunflower, or rapeseed be held to the same high standards.

Because if we’re only asking whether a product contains palm oil, we’re not asking the right question.

 

Oil palm in West Africa

When we think about oil palm cultivation, Southeast Asia often comes to mind. The industry’s rapid expansion there has been well-researched, particularly its effects on biodiversity and the environment. But oil palm cultivation is now rapidly expanding West Africa, where it grows naturally and has been traditionally harvested for centuries. Unlike the industrial-scale plantations that are common in Southeast Asia, many West African farmers cultivate oil palm alongside subsistence crops like cassava, rice, and banana in what’s known locally as ‘country palm’ farms. These small-scale farms stand in stark contrast to the industrial plantations which are now increasing across the region, where foreign companies are clearing rainforests to establish oil palm monocultures using intensive agricultural techniques.

 

While research on oil palm’s ecological impact in Southeast Asia is extensive, much less is known about its effects in West Africa. That’s why, as part of the Sustainable Oil Palm in West Africa (SOPWA) Project, we set out to study the biodiversity of ground-dwelling arthropods (insects, spiders, and similar creatures) across three different systems in Liberia: natural rainforest, traditional country palm farms, and industrial oil palm plantations.

 

Traditional and industrial oil palm farming impacts arthropod biodiversity in Liberia

Our findings were fascinating. While the total number of arthropods didn’t vary significantly across our study systems, the composition of these communities did. We saw shifts in the abundance of spiders (Araneae), springtails (Collembola), earwigs (Dermaptera), and flies (Diptera). We conducted species-level analyses on spiders, owing to their key roles as predators within tropical agricultural systems. Our spider results indicated that country palm supported the greatest number of spider individuals and species, and that all systems supported distinct spider assemblages.

 

Why is this important for oil palm cultivation?

Biodiversity isn’t just important for conservation – it directly affects agriculture. Spiders, for instance, prey on insect pests like slug moth caterpillars and bagworms, which can significantly damage oil palm yields. Maintaining high abundances of spiders within industrial oil palm plantations may lead to increased predation of pests, and potentially higher crop yields. Springtails and earwigs play a key role in decomposition and are prey for other arthropods, whilst flies are pollinators and decomposers. Therefore, the differences in arthropod biodiversity that we found across our study systems are not only important for conservation but also oil palm yields, owing to the vital ecosystem functions that many arthropod species provide.

 

How can we protect arthropods in oil palm systems?

To conserve arthropods in West African oil palm plantations, a few management strategies can be considered:

 

  1. Maintain forest fragments near plantations:Preserving patches of natural forest within or around oil palm farms can provide refuge for beneficial species, enhancing biodiversity and ecosystem services (e.g., pest control, pollination).
  2. Reduce herbicide use:Allowing understory vegetation to grow can create habitat complexity, supporting a wider range of arthropods.
  3. Diversify plantations:Integrating polyculture systems or tree islands within oil palm farms can improve species richness by increasing vegetation diversity.

 

While these approaches have been studied in Southeast Asia, their effectiveness in West Africa is still uncertain. More research is needed to determine how best to balance crop yields with conservation in this unique context. Identifying such strategies is a key component to ensuring the long-term sustainability of the West African oil palm industry.

Agricultural expansion is ongoing, and so is an ever-increasing overlap between agricultural land and natural habitats. Traditionally, this overlap has been viewed as an unavoidable threat to biodiversity. However, recent findings suggest that, with proper management, species can thrive in agricultural landscapes. This presents an opportunity to transform biodiversity monitoring systems into ones that embrace coexistence, enhance ecosystems, and support business performance without compromising sustainability.

 

A recent study by Maharani et al. examines such a system: PENDAKI, a pilot project developed by Borneo Futures for Austindo Nusantara Jaya (ANJ), in Indonesia. This citizen science-based monitoring program relies on plantation workers to collect biodiversity data during their daily tasks. The information gathered helps the company track species trends, understand habitat use, and inform conservation strategies within palm oil estates.

Since 2019, PENDAKI has recorded over 148,000 wildlife observations across seven estates, contributed by approximately 3,950 participants. Unlike traditional biodiversity surveys, which are often conducted by external experts and remove data from those working in the field, PENDAKI engages on-site staff directly. This not only democratizes data collection but also fosters a sense of ownership and pride among participants.

Interviews with PENDAKI contributors revealed that workers felt greater appreciation for biodiversity and valued being part of a company that prioritizes sustainability. Many reported gaining knowledge of species names, conservation statuses, and the importance of protecting wildlife.

Why Presence Alone Isn’t Enough

Understanding species abundance—not just their presence—is crucial for effective biodiversity management. It is very difficult to adaptively manage wildlife if you only look at species presence. What you need instead is an indicator of abundance, how this varies over time, and why. This allows an estate manager to plan and budget appropriate habitat and threat management to maintain wildlife populations of high conservation value.

PENDAKI employs special models designed for opportunistically collected wildlife observation through non-systematic surveys. These models account for imperfect detection and biases in data collection. The resulting data allow researchers to track species populations over time and measure biodiversity trends through the Living Plantation Index (LPI)—an estate-specific wildlife diversity index.

The data can also be used spatially. For example, orangutans were observed not only in protected forests but also in oil palm blocks (see map below), highlighting the need for wildlife corridors. Meanwhile, species like the White-breasted Waterhen showed higher occupancy in planted areas, challenging assumptions about wildlife distribution in agricultural settings.

A Cost-Effective Model for Conservation

One of PENDAKI’s biggest advantages is its affordability. The program costs just USD 0.14 per hectare annually, far less than traditional wildlife surveys or surveys using drones or camera traps. This makes it a scalable and financially viable approach to biodiversity monitoring.

Conclusion

This study demonstrates that citizen science can revolutionize biodiversity monitoring in oil palm plantations. By leveraging the power of local engagement, companies can gather valuable ecological data, support conservation, and strengthen their sustainability commitments—all while keeping costs low.
