A growing number of building professionals, policymakers, real estate developers, and philanthropic funders have awoken to the shocking volume of plastic building materials in use today and the devastating harm they cause to human and environmental health.  Find out why these leaders now see healthier alternatives to plastic building materials as the next frontier in the building and construction sector.

Designing Out Plastics Report

Key Takeaway #1

Plastics harm human and environmental health at every stage of their life cycle, from extraction through production and disposal.

Almost all plastics are made from fossil fuels, while the chemicals used to produce them are linked to cancer, reproductive harm, developmental issues, and other health harms. They also release microplastics which contaminate our environment and our bodies, and at the end of their life, plastics create massive amounts of waste. Tragically, these impacts fall hardest on children and on low-wealth, Indigenous, and communities of color.

Key Takeaway #2

The building sector is a leading driver of plastics use and continues to grow.

From flooring and siding to insulation and even paint, the building and construction sector accounts for 17% of global plastic production – second only to packaging. Plastic use in construction is on track to nearly double by 2050, intensifying its environmental and health harms. In fact, driven in large part by building materials, the plastics industry is expected to produce more plastic in the next 25 years than in all of history to date.

Building and construction

Key Takeaway #3

The building sector’s heavy reliance on plastics creates a unique and severe danger to human and environmental health.

The sector uses 70% of all PVC (vinyl) produced globally and 30% of all polystyrene—two of the most hazardous plastics. Plastic building materials make buildings less fire resistant, burning faster and hotter while generating more toxic chemicals than natural materials—posing an escalating threat as climate change fuels more severe wildfires.

Take a moment and look around. Try to find something—anything—that isn’t made with plastic. Your coffee cup lid, the synthetic fabric of your shirt, the carpet under your feet, the paint on the walls, the foam in your chair, even the “rubber” gaskets in your windows—they’re all plastic. Terms like polyester, nylon, vinyl, latex, acrylic, and spandex are just different names for the synthetic polymers we know as plastic.

Over the past 75 years, plastics have infiltrated daily life largely without question. Production skyrocketed from an estimated 2 million tons in 1950 to more than 470 million tons in 2019.1 And without intervention, plastic use is projected to surge in the decades to come.

Plastic’s ubiquity isn’t accidental. It has revolutionized modern life through life-saving medical devices, lightweight materials that improve fuel efficiency, and countless innovations. Despite their benefits, plastics are also one of our most pressing environmental and health challenges. They are made from fossil fuels and contribute to climate change. The chemicals used to make plastics have been linked to cancer, reproductive dysfunction, and other health harms. They pollute the air, water, soil, and our bodies, and create massive amounts of waste at the end of their—often too short—useful lives.

The good news? Change is happening. Across sectors and industries, sustainability professionals are reducing plastic use, municipalities are implementing plastic reduction policies, and innovative alternatives are reaching the market. We have unprecedented opportunities to drive meaningful change in reducing plastics’ impacts. Here we’ll provide facts you need to understand plastics’ impact and pathways forward.

What are plastics?

Plastics are synthetic or semi-synthetic materials made of polymers and chemical additives. Modern synthetic plastics came on the scene about 100 years ago.2 Almost all plastics (99%) are made from fossil fuels: oil, natural gas, or coal.3

How are plastic products made?

Plastic production begins with fossil fuel extraction; these fossil fuels are then refined and processed into petrochemicals. Petrochemicals are used to create different types of plastics with specific properties. Manufacturers shape these plastics into everyday products, often adding other chemicals to make them stronger, more flexible, or colorful.

How do plastics drive fossil fuel demand?

As the energy sector shifts to renewables, the fossil fuel industry has turned toward plastics as a way of maintaining demand for their planet-harming products.4,5 The International Energy Agency has predicted that petrochemicals, which are used to make plastics, will soon become the largest driver of global oil demand.6

How much plastic is made and thrown away?

Global plastic production was over 470 million tons in 2019.1 This is more than the weight of all the humans alive today.8 And annual production is projected to double by 2050.1 Industry is on track to create more plastics in the next 25 years than have been produced in the history of the world so far.1,a

When they think of plastics, people often think of packaging—and, indeed, packaging makes up a significant 31% of all plastics’ use. But the building and construction sector is the second-biggest contributor, responsible for 17% of global plastics production. From PVC pipes to nylon carpet and vinyl siding, tens of millions of tons of plastics are used in construction each year.10 Other major uses include transportation, textiles, consumer and institutional products, and electrical/electronic equipment and devices.

Plastic use by sector in 2019.10
Plastic use by sector 2019

Plastics last a long time and do not biodegrade, which translates to a lot of plastic waste.11 Humankind generated about 390 million tons of plastic waste in 2019,1 and this amount is projected to almost triple by 2060, reaching over 1.1 billion tons per year.9 The vast majority of plastic waste is landfilled, incinerated, or mismanaged (disposed of in uncontrolled dump sites, burned in open uncontrolled fires, or leaked to the environment where it builds up in ecosystems on land and in waterways).1,12 For example, international estimates project that by 2060, there could be a staggering 543 million tons of plastic accumulated in aquatic environments, including 160 million tons in the ocean.9

Why aren’t plastics as cheap as they seem?

While many plastic materials appear inexpensive, the price tag excludes substantial societal costs of harm to human health and the environment.13

Annually, production of plastics causes an estimated $592 billion in health harms globally.14,b A small subset of plastic-related chemicals generates an estimated $249 billion in medical and associated social costs every year in the U.S. alone.15 Plastic pollution is estimated to result in $100 billion of environmental damage every year.13 And these are conservative estimates.c Reducing plastics use can lead to major health and economic benefits.

The costs of climate change, too, are immense. Global warming increases the frequency of extreme weather events, each causing billions in damage. The U.S. faced 27 separate billion-dollar weather and climate disasters in 2024 alone—nearly matching the record-setting 28 events in 2023. These disasters resulted in over $182 billion in damages that year.16 Plastic production contributes to these mounting costs.

Government subsidies hide the real cost of plastics, with annual global subsidies totaling $7 trillion for fossil fuels and on the order of $30 billion for plastic production in the top 15 producing countries.17,18 A similar pattern exists at the local level. The Environmental Integrity Project reviewed 50 plastic plants built or expanded in the U.S. since 2012 and found that 32 of these plants received almost $9 billion in state and local tax breaks and taxpayer subsidies. Two-thirds of the more than 591,000 people living within three miles of the 50 new or expanded plants are people of color, revealing how environmental burdens often fall disproportionately on communities of color.19

These costs are paid by individuals and governments, not fossil fuel or plastic companies.14

What is plastic pollution?

The United Nations defines plastic pollution as “the negative effects and emissions resulting from the production and consumption of plastic materials and products across their entire life cycle.”13 Plastics generate pollution at every stage of their life, from fossil fuel extraction, through manufacturing, use, and disposal. This pollution—including greenhouse gases, microplastics, and toxic chemicals—harms everyone.

How does plastic pollution harm everyone?

Widespread pollution generated across the plastic life cycle is harming people and Earth’s ecosystems.12,20 Sometimes this pollution is readily apparent: smoke plumes or smells from a factory or plastic bottles in the gutter. Whether we can see or smell it or not, plastic pollution affects all of us—through greenhouse gas emissions; through the microplastic particles and toxic chemicals that make their way into our bodies from air, water, and food; and through impacts on the health of people and our planet. For example:

Climate change

Plastics contribute to climate change at every stage of their life cycle. Greenhouse gases are released during fossil fuel extraction, refining, and transportation. Plastic manufacturing processes emit additional climate pollutants. Even after use, plastic products continue damaging the climate as they degrade or burn in incinerators.21 Plastic production alone is responsible for over 5% of global greenhouse gas emissions and continues to grow.22

Microplastics

While plastics don’t biodegrade, they do break down into small and tiny particles known as micro- and nanoplastics. These particles range from about the size of an orange seed to the width of a strand of DNA, and they are everywhere.23 We are exposed to them through the food we eat, the water we drink, and the air we breathe. Microplastics have been found throughout human bodies, including our blood, kidneys, hearts, brains, and more, and there is evidence they build up over time.24–27 Project TENDR, an alliance of experts on toxic chemicals and brain development, notes that, “[b]abies today are born with their brains and bodies already contaminated with plastics. Micro- and nano-plastic particles have been found in the placenta and newborns’ first stool, with exposures continuing through breastmilk and infant formula.”28 Scientists are only just starting to learn how microplastics harm the health of children and adults, but research suggests they contribute to a range of adverse outcomes, such as cancer and infertility.29

Microplastics from paint?!

Did you know most paint is made with plastic? Researchers estimate that paint—including architectural, marine, road marking, general industrial, automotive, and industrial wood paint—is the largest source of microplastic leakage into oceans and waterways, accounting for 58% of known sources. A third of paint used in the architectural sector each year will eventually end up in the environment (oceans, waterways, and land), including an estimated 4 million tons of plastic.30

Toxic Chemicals

In addition to plastics themselves being a health concern as described above, plastics also use and release toxic chemicals throughout their life cycle. These chemicals are used throughout plastics production—extraction and refining of fossil fuels and production of chemicals, plastics, and products. In addition to “regular” releases of toxic chemicals that occur during production, each life cycle step and transportation of chemicals for each process also creates risk of fires, explosions, spills, and leaks.31 More than 16,000 different chemicals may be used to make, or are present in, plastics. Over 25% of these are known to be hazardous to human health or the environment, and most others lack information on their safety. This includes thousands of chemicals that are intentionally added to plastics to impart particular properties, such as making them more flexible, durable, or colorful.32 Chemicals used to create plastics pollute our air, water, soil, and bodies and have been linked to cancer, reproductive issues, children’s developmental harm, asthma, obesity, and many more health impacts.14,33–36

Human Health Impacts

Workers, communities, and users of plastic products face direct exposure to these harmful substances. Additionally, chemical wastes from plastic production and most plastic products themselves are landfilled or incinerated, burdening communities with additional pollution.1,14,34,37 Even recycling can release microplastics and toxic chemicals that affect human health.38,39

Environmental Impacts

Beyond local contamination, many plastic chemicals as well as microplastics spread globally through air and water, disrupting ecosystems and contaminating environments worldwide.1,32,36 Landfilling and incineration of plastic waste further burdens the environment with persistent pollution, while recycling processes can also release environmental contaminants.14,32,38,39

Who is disproportionately harmed by plastics?

While we are all harmed by plastic pollution, some of us are harmed more than others.

Children are especially vulnerable to chemical exposures. Beginning in the womb and continuing into adolescence, their cells and bodies are in a dynamic state of growth.40 Chemical exposures have many damaging effects. They can interrupt hormone systems and inhibit healthy brain development. Scientists suspect chemical exposures have contributed to the increased rates of childhood cancers like leukemia and neurodevelopmental disorders like ADHD present today.28,40,41 Exposure to toxic chemicals early in life can continue to harm health years later through effects such as reduced fertility and increased risk of obesity, asthma, and cancer.41

Communities near polluting facilities (chemical plants, landfills, incinerators, etc.) are directly affected by noise, odors, chemical emissions, and heavy duty diesel emissions.42–44 Such “fenceline” communities are disproportionately communities of color, Indigenous communities, and low-wealth communities.14,42,45 Often, industrial facilities are concentrated in “sacrifice zones” such as Louisiana’s Cancer Alley. This 85-mile stretch of communities along the Mississippi River between New Orleans and Baton Rouge is home to about 200 fossil fuel and petrochemical facilities. Residents of the area suffer from elevated rates and risks of reproductive, maternal, and newborn health harms; cancer; and respiratory ailments such as asthma.46 Hear directly from Cancer Alley residents in this video from Human Rights Watch.

Plastic chemicals and microplastics travel through air and ocean currents, concentrating in the Arctic and disproportionately affecting the land, water, and traditional foods of Arctic Indigenous communities.36,47 Climate change is also greater in Arctic regions which are warming almost four times faster than the planet as a whole. The health of these communities is threatened by the toxic impacts of the fossil fuel and plastics industry in addition to climate-induced threats to food security and community displacement.36

What can you do to fight against plastic pollution?

From the vinyl flooring under our feet to the polyester in our clothing, plastics surround us in ways we’re only beginning to fully understand. The evidence is clear: these ubiquitous materials are driving climate change, contaminating our bodies with chemicals and microplastics, and releasing toxic chemicals that disproportionately harm children, communities of color, Indigenous communities, and low-wealth communities. The hidden costs reveal the true price of our plastic dependency. 

Here are four concrete steps you can take right now to meaningfully reduce plastic use while protecting people and the environment:

  • Minimize new material use and reuse existing products when possible
  • Choose healthier materials when new products are necessary
  • Choose long-lived, timeless materials that remain in place for their full service life
  • Evaluate recycling claims critically, as recycling often perpetuates rather than reduces plastics’ harmful life cycle impacts

The same innovation that created this challenge can solve it. As sustainability professionals, we have the knowledge, networks, and influence to accelerate the transition already underway.

  1. OECD Global Plastics Outlook projects total plastic production 2025-2049 to be 16,285 million tonnes. Plastic production from 1950-2024 is estimated to total 12,193 million tonnes. Limited data is available for plastic production prior to 1950, but even assuming 1950 levels of production in each of the prior 15 years only marginally increases the total plastic production to date.
  2. All costs are in US dollars.
  3. Scarcity of data means that these estimates do not include a full accounting of cost, but they provide a general idea of the monumental and costly scale of impact.

Safer States offers valuable tools and support for creating safer solutions for human health and the environment, including a bill tracker that identifies state policies that move the needle toward achieving a healthier world.

SERA’s former Sustainability Manager Beth Lavelle recently wrote an op-ed in the Portland Business Journal that has inspired some interesting conversations in the office about architects’ and designers’ responsibility to safeguard the public’s right to a healthy and safe environment.

Recent court cases (Held v. Montana, Juliana v. U.S.) have led to decisions that directly tie climate change to constitutional rights. The Held decision found that the state of Montana, “. . . is failing to meet their affirmative duty to protect Plaintiffs’ right to a clean and healthful environment, and to protect Montana’s natural resources from unreasonable depletion.” Beth’s thought-provoking question is: If the U.S. government can be found at fault for depriving the public of a clean and healthy environment, does the building sector risk similar liability?

Beth’s piece focuses on the need for greater regulation to require the use of green building strategies, and I argue that the same is true for healthy building materials. When designers, builders, and developers choose toxic materials, they risk liability for the harm they cause to the users of their spaces as well as those involved along the supply chain.  

As architects and designers, we bear a profound responsibility to shape the world around us, not just aesthetically, but also ethically and responsibly. Our designs don’t exist in isolation; they interact intimately with the lives of individuals, communities, and the environment. In this regard, the materials we specify play a pivotal role in shaping the health and safety of the spaces we create.

The Challenge: Competing Priorities and the Bottom Line

Cost & Performance:
From a material cost point of view, healthier materials can often be comparable to the price points of more toxic materials. However, the time and labor hours spent researching, validating, and tracking healthier material selections and certifications can significantly add to total project costs, and this is often a barrier to designers’ selection process. The reality is, it takes less time to select finishes when we’re only focused on performance and aesthetics, without the added layer of validating and certifying material health properties too. 

There’s little motivation for clients to choose healthy materials:
Clients are faced with a variety of pressures and priorities, like staying within budget and getting the project done on schedule. They also might assume that the government is regulating and eliminating toxic products from the market – which is not the case. Without awareness and the drive from company values, regulatory requirements, or consumer demand, there may be little motivation for clients to choose healthier materials, especially in any case where there is a cost premium. As much as designers can advocate for healthier materials on our projects, we are often limited by project priorities and available project fee hours.

Navigating the complexities of certifications–information overload:
With all of the project responsibilities designers must juggle, and a vast landscape of material certifications with different levels of rigor and limited considerations beyond the use phase, it can be overwhelming and burdensome to understand and navigate healthier material product selection. After all, we are not scientists!

Useful Options and Better Strategies

The good news is, we are beginning to see more resources to help designers make healthier product decisions, regardless of client priorities and certification goals. One of SERA’s go-to resources is Habitable’s Informed Product Guidance. The intuitive red-to-green color ranking compiles decades of research to summarize key health impacts and considerations across the life-cycle of common building materials.

The first step? Avoid selecting materials in the red categories, and opt for yellow or green instead. Want to learn more? Expand the drop-down menus to read about the health impacts of that material type. Importantly, this tool does not suggest specific manufacturers or products. Instead, it provides guidance about types of materials, making it easier for designers to prioritize what to look for when generating finish palettes and selecting specific products. Identifying safer building product types means that designers don’t have to do as much research or memorize long lists of materials. It’s like shopping the perimeter at grocery stores, where the fruits, vegetables, and other fresh goods are usually laid out. The center aisles are where all the candy, super-processed snacks, and other less natural products lurk–if you stay out of that area, you can be confident that you’ll be eating relatively healthful foods, even without knowing the latest updates on ingredients or additives. (The almonds in that candy bar may be certified organic, but we all know it’s not a very healthy option, right?). Habitable’s Informed Product Guidance can help get you to the right aisles—and know that you’ll be specifying products that are generally safer for building occupants, workers, and communities.

Considerations from the science side: looking at materials through the life-cycle lens

For example, it’s common for housing developers to opt for Luxury Vinyl Tile (LVT) due to its durability, easy installation, and low first cost. However, we can see by looking at the Informed Product Guidance that LVT is in the red category. Phthalates, chemicals known to disrupt the hormonal system, were once commonly found in LVT. While in recent years we’ve seen more and more phthalate-free LVT products become available, even “better” vinyl is still not a preferred material! This is because of the toxic processes required to make polyvinyl chloride (PVC), and the toxic pollution created when it’s disposed of. And let’s not forget, vinyl is a form of plastic derived from fossil fuels, so its use continues our reliance on the polluting fossil fuel industry at a time when we are electrifying our buildings to decrease fossil fuel use.

What does that all really mean? Not only can building products have negative health impacts on the daily occupants of a space, they often impact installers, factory workers handling the material production, and the communities living near those processes. And unfortunately in the case of housing, renters are likely unaware of any of this when selecting a place to live. Which brings us back to the dilemma for designers: is it really ethical to specify a material when we know its negative health impacts? And if we make the decision to take care in our specifications, how can we encourage our clients to approve healthier alternatives?

The Long-Term Solution: Increased Demand and Regulation

From our perspective, it remains essential for designers and building professionals to make a commitment to disrupt the status quo, prioritize implementing better product selections on our projects, and have meaningful conversations with clients about the importance of healthier and non-plastic materials. In other words, continue to make noise! At the same time, what’s really going to make a change in the industry is an increase in demand for healthier products.

One avenue for increased demand can come from consumers. Apartment dwellers, home owners, office workers, hotel guests, and restaurant-goers (and so on!) have the right to know whether a material or product contains toxic substances or uses them in manufacturing. More often than not, consumers are in the dark about the toxics found in building products due to lack of visibility and awareness. Much like nutrition labels found on food products, it’s reasonable to expect that building materials and finishes in the public marketplace could include clear labels like hazard pictograms or ingredients lists. At a minimum, this may help consumers start to have some visibility into the harmful chemicals used in the built environment. Imagine a world where healthy buildings, spaces, and materials are desired and actively sought-out by the general public! That just might be enough incentive to drive market change. 

While visibility and awareness may increase some demand for healthier materials, the burden of change is broader than that. Arguably, the biggest agent of change will come from government regulation to reduce harmful substances used in consumer products in the first place. For example in the EU, REACH Regulation aims to protect health and the environment against harmful chemicals. And the Classification, Labeling and Packaging (CLP) Regulation ensures hazards posed by chemicals are clearly communicated when placed on the market, enabling consumers to make informed decisions when purchasing or using products. It is critical that the U.S. government begins to take responsibility for policies and regulation that better protect citizens and the environment, and boost innovation for safe and sustainable chemicals. 

Looking forward, we envision a world where healthier materials will be actively sought out by consumers, more strictly regulated at the government level, and ultimately become the baseline standard for all construction and building materials and finishes. For now, we must continue to advocate for change, educate ourselves (using tools like Habitable’s Informed Product Guidance to step up from red-ranked products!), and intentionally make healthier product selections on our projects. This responsibility isn’t just a passing concern; it’s a duty we owe to ourselves, to each other, and to future generations.
