Insulation selection has generally focused on prioritizing a product’s ability to reduce greenhouse gas (GHG) emissions from building operation, though increasingly considerations include GHG emissions from a material’s life cycle, from manufacture through disposal (known as embodied carbon).
However, this singular focus on GHGs fails to account for other harmful emissions associated with the life cycle of these materials, including toxic pollution that disproportionately burdens Black, Indigenous, people of color (BIPOC), and/or low-income communities. As billions of pounds of new insulation is being installed in buildings each year, failure to address these toxic impacts will mean that building decarbonization efforts will further entrench environmental injustice.
Healthy Building Network (HBN) joined NRDC and Energy Efficiency for All in an analysis of the life cycle chemical and environmental justice impacts of two popular building insulation materials—fiberglass and spray polyurethane foam (SPF).
The analysis found that both SPF and fiberglass release pollution into BIPOC communities over their life cycles, but SPF carries a much heavier pollution burden. The combined population surrounding the facilities that manufacture the key ingredient of SPF has almost double the percentage of Latino people compared to the U.S. overall. These facilities reported releasing an average of about 560,000 pounds of related hazardous chemicals every year and have a history of noncompliance with EPA regulations. Our previous research also found that spray foam has significant hazardous chemical concerns during installation and use in buildings.
Regarding embodied carbon, while the specifics vary, studies (such as here, here, and here) consistently show that closed cell SPF has significantly higher embodied carbon per R-value than fiberglass insulation. Further, SPF is made from almost entirely fossil fuel-derived inputs, with no recovery, reuse, or recycling of the material—necessitating continued extraction and refining of fossil fuels to produce this insulation product. Overall, comparing material health, environmental justice, and embodied carbon impacts between SPF and fiberglass, fiberglass is preferable on all accounts.
However, fiberglass manufacturing still releases hazardous pollution into communities who are disproportionately BIPOC and/or low income, and many fiberglass facilities have exhibited regular noncompliance with EPA regulations. Fiberglass manufacturers can reduce and eliminate such pollution by using less hazardous chemistries. For example, all four U.S. manufacturers reported reduced releases of formaldehyde by changing to safer binder formulations for many of their products between 2002 and 2015.
Why It Matters
As laid out in the Equitable and Just National Climate Platform:
“To achieve our [climate] goals, we will need to overcome past failures that have led us to the crisis conditions we face today. Past failures include the perpetuation of systemic inequalities that have left communities of color, tribal communities, and low-income communities exposed to the highest levels of toxic pollution and the most burdened and affected by climate change. The defining environmental crisis of our time now demands an urgency to act. Yet this urgency must not displace or abandon the fundamental principles of democracy and justice…Unless justice and equity are central components of our climate agenda, the inequality of the carbon-based economy will be replicated in the new economy.”
To truly be part of a just and equitable transition to a clean economy, climate solutions like building insulation must advance the well-being of BIPOC and low-income communities. We recommend that embodied chemical and environmental justice impacts drive material decision-making on par with consideration of GHG emissions.
Your Action Today = Healthier, More Just Future
In general, there are significant opportunities to improve the life cycle of building insulation materials through avoiding hazardous chemicals, implementing circularity, and taking other actions stemming from the principles of green chemistry and environmental justice.
Manufacturers and policymakers should advance transparency about what is in a product, how and where it is made, and the hazardous releases that occur throughout its life cycle. In the meantime, those who choose building materials can start by avoiding hazardous chemicals in a product’s content to help protect not only building occupants and installers, but also others impacted by those hazardous chemicals throughout the supply chain. Our InformedTM product guidance can help you choose safer materials.
All stakeholders–including manufacturers, policymakers, and those who choose building materials–should support the leadership of frontline communities and make changes to their own practice so that all families have healthy places to live, learn, work, and play.

PFAS are used in paints, food packaging and even cosmetics. We know they are in our water, air, soil and bodies – but less about how they will affect us.
The Louisville Charter for Safer Chemicals, endorsed by over 100 organizations, confronts the chemical industry’s role in the climate crisis and provides guidance for advancing environmental justice in communities disproportionately affected by harmful chemical exposure.
This report discusses how President Biden’s Executive Orders need to go further than examining energy sources to combat the climate crisis, emphasizing the need for the chemical industry to adapt and innovate, considering its significant impact on greenhouse gas emissions and environmental health.

The 2021 winners were announced in a virtual ceremony. The full list of awardees is below.
Congratulations, Gina!
Healthy Building Network (HBN) and 100+ organizations stand united behind the new Louisville Charter for Safer Chemicals, a roadmap for transforming the chemical industry to one that is no longer a source of greenhouse gas emissions and significant human and environmental health harms.
The goal of the updated charter is to protect human health and the environment and achieve environmental justice for all who experience disproportionate impacts from cumulative chemical sources, including people of color, low-income people, Tribes and Native/Indigenous communities, women, children, and farmworkers.
The original Charter was created in 2004; at that time, HBN joined a broad coalition of grassroots, labor, health, and environmental justice groups in an extensive process initiated by community organizations in Louisville, KY. Louisville’s “Rubbertown” area hosted 11 industrial facilities that released millions of pounds of toxic air emissions every year. The Charter was named in honor of this city and all of the communities across the nation exposed to toxic chemical contamination—starting with the people who are harmed first and worst. We participated in the 2021 update process, supporting the efforts of the most heavily impacted communities to more explicitly address the chemical industry’s massive contribution to the climate crisis, and the need to advance environmental justice in communities who are disproportionately impacted.
The Louisville Charter is a unifying guide for everyone working to ensure that toxic chemicals are no longer a source of harm, from local and national policy-makers and labor organizers, to health care workers and concerned community members, to committed leaders in the building industry. It is meant to be versatile and used in a wide variety of contexts for one overarching purpose: to overhaul chemical policies in favor of safety, health, equity, and justice, and avoid false solutions that simply shift harms to other people and places.
HBN is proud to be a signatory of the Charter and join this diverse and intersectional community of partners demanding urgent action to protect, strengthen, and restore our most vulnerable communities.

In this article, we aim to expand your thinking about the cost of materials to account for the costs borne by individuals and fenceline communities who are exposed to toxic chemicals every day. The bottom line is that some products can be sold cheaply because someone else is carrying the burden of the true cost.
When you shop for a flooring product, what do you consider? Perhaps you think about the look and feel of the product and its durability. You likely also consider the price. The cost of using a material is influenced by the cost to purchase the product itself, the installation cost, maintenance costs, as well as how long the product will last (when you will have to pay to replace it). These are all internalized costs, paid by the building owner.
These costs alone, however, do not consider the full impacts of materials along their life cycles. More and more building industry professionals are paying attention to the content of building products and working to avoid hazardous chemicals in an effort to help protect building occupants and installers from health impacts following chemical exposures. To understand the true, full cost of a product, we must look beyond just the monetary cost of purchasing and maintaining a product.
Many of the costs associated with products are more or less hidden when choosing a building material. Just a few of these hidden costs are outlined below.
Toxic Chemical Impacts on Human Health
The US Occupational Safety & Health Administration (OSHA) estimates that American workers alone suffer more than 190,000 illnesses and 50,000 deaths per year that are related to chemical exposures. These chemical exposures are tied to cancers, as well as other lung, kidney, heart, stomach, brain, and reproductive diseases.1
While some workers may see greater exposures to hazardous chemicals, all of us are impacted. Many of you are likely familiar with PFAS, aka per- and polyfluoroalkyl substances. PFAS have been used in a wide range of applications, including stain-repellent treatments for carpet and countertop sealers. The widespread use of PFAS has led to extensive contamination of the planet and people. Increasing research and attention to this group of chemicals has led to some quantitative understanding of the costs to society of their use. A recent publication in Environmental Science and Technology outlined some of the true costs of PFAS chemicals. The authors highlight that, “A recent analysis of impacts from PFAS exposure in Europe identified annual direct healthcare expenditures at €52–84 billion. Equivalent health-related costs for the United States, accounting for population size and exchange rate differences, would be $37–59 billion annually.” Importantly, they further call out the fact that, “These costs are not paid by the polluter; they are borne by ordinary people, health care providers, and taxpayers.”2
And this is just the cost of one group of chemicals. Another recent study estimated the cost of US exposures to phthalates, a group of chemicals used to make plastics more flexible, to be approximately $40 billion or more due to loss of economic activity from premature deaths.3 While more research is needed, the scale of these estimated costs is staggering.
Environmental Contamination Costs
The release of PFAS chemicals has contaminated water supplies globally. About two-thirds of the US population receives municipal drinking water that is contaminated with PFAS. Reducing the levels of PFAS in drinking water can be expensive, and none of the methods fully remove PFAS. In the Environmental Science and Technology study mentioned above, the authors note that “following extensive contamination by a PFAS manufacturer in the Cape Fear River watershed, Brunswick County, North Carolina is spending $167.3 million on a reverse osmosis plant and the Cape Fear Public Utility Authority spent $46 million on granular activated carbon filters, with recurring annual costs of $2.9 million. Orange County, California estimates that the infrastructure needed to lower the levels of PFAS in its drinking water to the state’s recommended levels will cost at least $1 billion.” Again, these costs are typically not paid by the polluter but shifted to the public.4
Climate Change Impacts
Chemicals used in the production of some PFAS are ozone depleters and potent greenhouse gases. New research released in September by Toxic-Free Future, Safer Chemicals Healthy Families, and Mind the Store ties the release of one such chemical, HCFC-22, to the production of PFAS used in food packaging. The reported releases of this one chemical from a single facility is equivalent to “emissions from driving 125,000 passenger cars for a year.”5
The costs of climate change impacts are immense. For example, the number of billion-dollar disasters and the total cost of damages due to natural disasters have been skyrocketing. The National Oceanic and Atmospheric Administration describes how climate change contributes to increasing frequency of some extreme weather events with billion-dollar impacts. They outline the broader context of these extreme weather events saying that, “the total cost of U.S. billion-dollar disasters over the last 5 years (2016-2020) exceeds $600 billion, with a 5-year annual cost average of $121.3 billion, both of which are new records. The U.S. billion-dollar disaster damage costs over the last 10-years (2011-2020) were also historically large: at least $890 billion from 135 separate billion-dollar events. Moreover, the losses over the most recent 15 years (2006-2020) are $1.036 trillion in damages from 173 separate billion-dollar disaster events.”6

Environmental Injustice
In the US, communities of color and low-income communities are disproportionately impacted by environmental pollutants.8 These communities often face hazardous releases from multiple sources due to high concentrations of manufacturing facilities near their homes. The area along the Mississippi River between New Orleans and Baton Rouge is known as “Cancer Alley” because of the concentration of industrial activity and the associated elevated cancer risks.9 Figure 2 maps facilities that report to EPA’s Toxics Release Inventory (TRI) in this area. These are facilities that release or manage hazardous chemicals that require reporting to EPA.
The city of Geismar, LA is home to 18 TRI facilities. These facilities reported a total of over 15 million pounds of on-site releases of hazardous chemicals to air, water, and land in 2019.10 Several of these facilities produce chemicals used in the building product supply chain. Two facilities produce chlorine for internal or external production of PVC, which can be used to make pipes, siding, windows, flooring, and other building products.11 Two other facilities manufacture a key ingredient of spray foam insulation, MDI. Some of these facilities have a history of noncompliance with EPA regulations, one having significant violations for eight of the last twelve quarters and another having significant violations for all twelve of the last twelve quarters.12 Surrounding communities are impacted by regular toxic releases from these facilities and are vulnerable to accidents involving toxic chemicals. For example, an explosion and fire at the vinyl plant in 2012 released thousands of pounds of toxic chemicals, led to a community shelter in place order, and shut down roads and a section of the Mississippi River.13
More than 5,000 people live within three miles of one or more of these four facilities. This community is disproportionately Black — 35% of the population compared to 12% in the US overall. Thirty percent of the population is children, with about 1500 kids under the age of 18. This community has a higher estimated risk of cancer from toxics in the air than most places in the US — almost four times the national average.14
The message we hope you take away from this article is that we must move beyond discussions based purely on the material costs or up-front costs of products. We must all work together to acknowledge and shed light on the true costs that toxic chemicals have within our society and on specific communities. The impacts of hazardous chemicals are, of course, not just monetary –people’s lives are significantly impacted in multiple ways. The current system subsidizes cheap products by robbing individuals of the opportunity for healthy lives and for children to play, and grow up, and enjoy a full and normal life.
Unfortunately, there is not currently enough information available to make detailed cost accounting broadly possible, and no framework exists for accounting for and comparing the full extent of product costs. Transparency about what is in a product, how the product is made, and hazardous emissions – beyond those required to be reported by law – is critical. Programs that place extended responsibility on manufacturers to manage materials at their end of life (as part of extended producer responsibility or EPR)15 can be a starting point for conversations about the full life cycle impacts of products and can help hold manufacturers accountable for a broader array of costs, once they are better understood.
In the meantime, Habitable works to incorporate a life cycle chemical perspective into our safer material recommendations like our Informed™ product guidance and Pharos database. These tools are a work in progress initially focused on avoiding hazardous chemicals in a product’s content. As a starting point, this helps protect not only building occupants and installers, but also others impacted by those hazardous chemicals throughout the supply chain. When hazardous chemicals are used, it is likely that someone throughout the supply chain is impacted. Informed™ can help you choose safer building products based on the information that we have today as we work to expand our incorporation of life cycle chemical impacts into our research and to provide guidance on a broader range of materials.
Habitable looks forward to continuing to identify and provide the critical data needed to assist in decision making with a more comprehensive view of the true costs of materials, and to developing resources to help communicate the collective return on investment seen by a society where all people and the planet thrive.
Coming Clean and EJHA teamed up with NRDC, Rashida Jones, and Molly Crabapple to tell the stories of vulnerable fenceline communities living near over 12,000 high-risk chemical facilities in America, urging action to protect their health and safety.
Some people can probably name a chemical that contributes to climate change, whether that is carbon dioxide or methane. But what about other chemicals that you are not as familiar with? In the building materials world, these may include fluorinated blowing agents used in some foam insulation. The agents either have high global warming potential (GWP) or use chemicals in their production that have high GWP.1 Another example is the release of the toxic, global warming, and ozone-depleting chemical carbon tetrachloride in the enormous supply chain of vinyl products, otherwise known as poly vinyl chloride (PVC).2 Purveyors of vinyl products, you may unwittingly be contributing to global warming!
Yes, the way in which certain chemicals contribute to climate change is important, but this interplay is not the only consequence of chemicals on our climate. Climate change is also altering how toxic chemicals impact our health and the health of the environment – as the world warms, reducing our exposure to toxic chemicals becomes ever more important.
While most toxic chemicals do not cause climate change, they do affect how climate change might impact you. These impacts compound as more chemicals are produced or utilized.15 In 1970, the U.S. produced 50 million tons of synthetic chemicals.16 In 1995, the number tripled to 150 million tons, and today, that number continues to increase.17
Very few of the tens of thousands of chemicals on the marketplace are fully tested for health hazards, and details on human exposure to these chemicals are limited.18 We are exposed to these chemicals every day, in varying quantities and mixtures. Over a lifetime, the small exposures add up. Predictions of health outcomes from long-term exposure are already fuzzy at best, but add on the component of climate change and the mystery deepens.19 While researchers continue to study climate change and chemicals to answer the questions we have, there are steps that we can take to help mitigate the negative impact of climate change on chemicals.
Habitable’s Small Piece of the Pie — How We’re Keeping Consumers Safe
We cannot remove all chemicals from our lives and many play important roles, but, we can follow the precautionary principle. If there is a less toxic chemical or product available that meets our requirements, we should use it. At Habitable, our work is guided by the precautionary principle—otherwise known as ‘better to be safe than sorry.’ Our chemical and product guidance provides advice on better products.Empowering industry to choose safer chemicals and products helps reduce the burden of toxic chemicals on all people and the planet – especially our most vulnerable populations.
Why We Can and Must Do Better
Between climate change and toxic chemicals, it could be easy to push toxic chemicals to the side as a someday problem and choose to tackle climate change first. But the truth is that the impacts of toxic chemicals are real and happening today and will only get worse in a warming world. These two issues are connected and influence each other’s outcomes. Climate change is having a significant impact on our world, but prioritizing reduction of toxic chemicals can reduce the negative consequences that climate change will have on chemicals, and consequently on us.
