Greenwashing Diapers: Are “Eco-Friendly” Diapers Just a Scam?
The disposable diaper industry has seen significant growth, with expectations to reach $159.3 billion by 2032, up from $85.2 billion in 2023. This growth is driven by factors like rising birth rates and increasing awareness of hygiene (IMARC, 2024). Despite the benefits it offers parents, disposable diapers contribute heavily to environmental issues. They are the third most common waste in landfills and can take up to 500 years to decompose, leaching harmful pathogens into surrounding soil and water (Tokat et al., 2024). The non-biodegradable materials, such as polypropylene, are made from petroleum products, leading to carbon emissions and microplastic contamination (Capezza et al., 2023). As consumers become more aware of these environmental impacts, some diaper companies claim to offer eco-friendly alternatives, but often these claims are misleading, a practice known as greenwashing.
Greenwashing refers to the marketing tactic where companies falsely promote their products as environmentally friendly without making meaningful changes to the product or its production processes. The United Nations defines greenwashing as “misleading the public to believe that a company or other entity is doing more to protect the environment than it is” (United Nations, 2024). This allows companies to profit from the growing demand for eco-friendly products while continuing business as usual. In recent years, the UN has focused on educating consumers about greenwashing, emphasizing how it diverts attention from real solutions and misleads well-meaning customers.
Diaper companies use greenwashing tactics to advertise their products as sustainable, highlighting eco-friendly materials or partnerships that sound good on paper. Some common methods include: 1) labeling diapers as “sustainably sourced” or “plant-based” when most of the product is still made from non-biodegradable materials; 2) making vague promises, like replanting a small number of trees; 3) promoting chlorine-free bleaching methods, even though non-chlorine bleaching is safe and widely used; and 4) altering packaging with earthy colors or visuals of nature to make the product seem environmentally friendly. These tactics mislead consumers, leading them to believe they are making eco-conscious choices.
Misleading Labels
Polylactic acid (PLA), a biodegradable polymer derived from plant sugars, is often marketed as a sustainable alternative to plastics in products like diapers. Companies claim that PLA is biodegradable and recyclable, but this material requires specific recycling processes that most facilities cannot accommodate. In general, PLA takes about 80 years to break down in a landfill, significantly reducing its environmental benefits (Gianeco, 2024). Moreover, the processes used to create PLA are highly industrialized, relying on fossil fuels like sulfuric acid, which is used in its synthesis. This increases demand for sulfuric acid, a material already under pressure due to its extensive use in industries like fertilizer production and lithium battery manufacturing (Maslin et al., 2022; USGS, 2022).
Despite PLA’s claims, laboratory testing of several “plant-based” diapers reveals that they contain very little PLA. In one study, only one diaper out of four marketed as “eco-friendly” contained any PLA, and even that had non-biodegradable components such as polyethylene, polyester, and polypropylene, which can take hundreds of years to break down (Manteco, 2024; Nghiem, 2021).
Replanting Harvested Trees – Does it Matter?
Cellulose, a tree-based fiber, is the core material in most diapers due to its absorbency. However, the environmental impact of harvesting trees raises concerns about deforestation. To mitigate this, some companies claim to use sustainably sourced cellulose and promise to replant trees to offset their environmental impact. These claims often focus on partnerships with Forest Stewardship Council® (FSC®) certified sources, which ensure that forests are regenerated as trees are harvested. While these efforts may sound promising, they often have little meaningful impact. For instance, one company’s promise to replant 1,000 trees is negligible when compared to the number of trees required for diaper production—one child may require the equivalent of 20 trees’ worth of cellulose over the course of their diaper use (Clean Water Action, 2024). Furthermore, it takes years, sometimes decades, for these newly planted trees to reach a size that can absorb significant amounts of carbon dioxide, making these replanting efforts an ineffective method for carbon offsetting (Wendel and Smith, n.d.; Minerva Action Group, 2024).
Branding: How Packaging and Product Appearance Affect Sentiment
Another common greenwashing tactic involves altering packaging to make it appear more eco-friendly. Diaper companies often use earthy colors like green and brown, or images of trees and plants, to create a visual association with nature. Research has shown that consumers perceive products in green packaging as more environmentally friendly, even if the product itself is not (Seo and Scammon, 2017). Some companies also use dyes to make the diapers appear more natural by giving them a brown tint, which further suggests an eco-conscious product, though this is more about marketing than actual sustainability.
Chlorine-Free: Does it Matter?
The marketing of “chlorine-free” diapers is another greenwashing tactic commonly used in the diaper industry. In the past, wood pulp used in diaper production was bleached with elemental chlorine, but this process was replaced with chlorine-free methods in the 1980s due to concerns about dioxins, toxic byproducts. However, the alternative methods—elemental chlorine-free (ECF) and total chlorine-free (TCF)—still use chlorine compounds like chlorine dioxide. These methods do not produce harmful dioxins, and research shows that dioxin exposure from diapers is negligible (Axegård, 2019). Despite this, companies use “chlorine-free” labels to imply their products are safer, even though the process is standard and widely accepted in the industry.
Eco-Friendly: What Are They Actually Made of?
A laboratory analysis of four diaper brands marketed as “eco-friendly” found that the majority of their materials were non-biodegradable, including polypropylene and polyester. While the core material of each diaper was cellulose, only one diaper contained a small amount of PLA. The rest of the diaper components were made from plastics that can take hundreds of years to decompose, revealing that these products, despite their eco-friendly labels, are primarily made from materials that do not break down quickly in landfills.
Are There Viable Alternatives?
While disposable diapers provide convenience, their environmental impact highlights the need for sustainable alternatives. Cloth diapers, typically made from cotton, bamboo, or hemp, are more eco-friendly due to their faster-growing nature. For example, cotton cloth diapers require less than 10 kg of cotton for two years’ worth of use, while a child’s disposable diapers require approximately 20 trees’ worth of cellulose (Meseldzija et al., 2013; Clean Water Action, 2024). However, cloth diapers have their drawbacks, including the need for regular washing, which increases water, energy, and detergent use, particularly in areas with water scarcity (Hoffman et al., 2020). Diaper services, which use commercial-grade washing machines, may offer some advantages but can still result in higher water and energy consumption, and the added carbon footprint from delivery services can offset some of the benefits.
While greenwashing has become a widespread issue in the diaper industry, it is important to recognize that the environmental damage caused by disposable diapers is not insurmountable. The shift toward genuine sustainability in the diaper market is not only possible but necessary, as awareness of climate change and environmental conservation continues to grow. There are several aspects to consider when evaluating the true environmental impact of diaper products, and businesses that wish to contribute positively to the environment must make lasting, significant changes across their production processes.
Corporate Responsibility and Regulation
One of the primary issues with greenwashing in the diaper industry is the lack of transparency and accountability. Companies are not always required to disclose the full range of materials used in their products or the processes involved in production. Often, brands make broad claims about their environmental efforts without backing them up with data or certifications from third-party organizations. Regulatory bodies, such as the United States Environmental Protection Agency (EPA) and the European Union’s Ecolabel program, are working to create clearer, more enforceable standards for sustainable product claims. This could help reduce the prevalence of greenwashing by holding companies accountable for their marketing practices. However, until such regulations are standardized across industries, including diaper production, it is important for consumers to remain skeptical of broad sustainability claims.
As companies continue to expand their sustainability efforts, it’s essential that any steps taken toward environmental responsibility are measurable, transparent, and verifiable. Transparency in supply chain management, especially concerning the sourcing of raw materials, is crucial for fostering trust with eco-conscious consumers. Genuine sustainable practices could include using renewable energy sources, minimizing water usage, and reducing waste throughout the manufacturing process. In this way, diaper companies could not only reduce their carbon footprint but also contribute to broader global sustainability goals, like the United Nations’ Sustainable Development Goals (SDGs), particularly in terms of responsible consumption and production (SDG 12).
The Role of Consumer Education
Consumers must also play a key role in pushing the diaper industry toward more sustainable practices. This requires education on what constitutes a truly eco-friendly diaper, which involves understanding the long-term environmental impact of the materials used, the carbon footprint associated with production, and the disposal process. Consumers who are informed about the realities of greenwashing tactics can more effectively advocate for companies to take genuine steps toward sustainability. Awareness campaigns and educational resources that explain the significance of product certifications, such as FSC (Forest Stewardship Council) for sustainably sourced materials or Cradle to Cradle certification for sustainable design, can help shoppers make more informed choices.
It is also crucial to raise awareness of the unintended consequences of popular “eco-friendly” alternatives, like PLA-based diapers. While they may sound environmentally friendly on the surface, their true ecological footprint is often much larger than advertised. By examining the full lifecycle of a product—from sourcing raw materials to end-of-life disposal—consumers can better understand the limitations and potential benefits of various alternatives. For example, while PLA is biodegradable, its degradation process is slower in natural landfill conditions than in controlled industrial composting environments, limiting its practical eco-advantage. Knowing the entire picture allows consumers to choose the truly better alternatives, such as cloth diapers, which are reusable and require far fewer resources over time, or diaper services that provide energy-efficient laundering processes.
The Circular Economy: Moving Beyond Disposable Diapers
One promising solution to the environmental challenges posed by disposable diapers lies in the concept of the circular economy. This model encourages the design of products that can be reused, repaired, or recycled, rather than thrown away after a single use. In the case of diapers, a circular approach could involve developing materials that are both biodegradable and recyclable, reducing their environmental impact both in terms of waste and resource consumption. Some diaper brands have explored the possibility of creating products with recyclable components, but this remains an area where more innovation and research are needed.
Additionally, diaper reuse and service-based models offer a potential pathway for significantly reducing environmental waste. These models often involve the collection, cleaning, and redistribution of cloth diapers, providing a sustainable and convenient solution for busy parents. By centralizing the laundering process, diaper services can use energy-efficient machines and reduce water waste, creating a more environmentally friendly alternative to traditional disposable diapers. However, as noted earlier, the success of diaper services is dependent on the scale and infrastructure involved. The environmental benefits are maximized when services operate at a larger scale, where economies of scale reduce water and energy consumption.
While not as mainstream as disposable diapers, cloth diapers and reusable diaper services offer an environmentally-conscious option for parents. The long-term sustainability of cloth diapers—especially when washed with eco-friendly detergents and dried using energy-efficient methods—far outweighs that of disposable diapers. Cloth diapering can be seen as an example of a product within a circular economy, where the use phase extends for multiple children, decreasing the overall environmental impact.
Moving Toward Authentic Sustainability
As the demand for disposable diapers continues to rise, the environmental impact of these products cannot be ignored. The diaper industry must evolve to address the growing concern over waste, deforestation, and carbon emissions associated with disposable diapers. Companies engaging in greenwashing only delay the progress needed toward more sustainable and responsible manufacturing practices. While greenwashing tactics may continue to mislead consumers, the increasing availability of reliable third-party certifications, along with growing consumer demand for real change, presents an opportunity for the diaper industry to clean up its act.
It is essential for consumers to remain vigilant, demanding accountability from companies making sustainability claims. By becoming better informed and making conscious purchasing decisions, consumers can drive the industry toward authentic environmental stewardship. Whether by choosing truly eco-friendly disposable diaper alternatives or opting for cloth diapering solutions, each individual action contributes to a larger movement of sustainability that has the potential to significantly reduce the environmental footprint of diaper production and waste. As the diaper industry continues to grow, so too should its commitment to a cleaner, greener future.
Takeaways
The diaper industry is rife with greenwashing tactics, with companies misleading consumers by using terms like “plant-based” and “chlorine-free” without making significant changes to the materials or production processes. Consumers must be cautious and informed about the true environmental impact of the products they purchase. Laboratory tests reveal that most “eco-friendly” diapers still rely heavily on non-biodegradable polymers. To make truly sustainable choices, consumers should look beyond misleading labels and understand the real environmental impact of the products they use, considering alternatives like cloth diapers or diaper services that reduce waste and support circular economies
