Safer States is a national alliance of environmental health groups led by state-based organizations working towards a healthier and more just future. 

By addressing critical issues such as toxic chemicals, plastics, and climate change, Safer States empowers collective action through its extensive network and capacity-building initiatives. The organization’s resources focus on ensuring clean air and water, holding polluters accountable, and promoting the development of safer consumer products. 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.

This website explores the concept of planetary boundaries, a framework of nine key Earth system processes that humanity must stay within to ensure long-term sustainability and avoid irreversible environmental harm.

Earthjustice lays out the pillars of the argument against the oil and gas industry’s push for a petrochemical boom, which threatens to lock in more climate pollution and toxic chemicals in already overburdened low-income and minority communities.

The Planetary Health Alliance is a global consortium of over 400 organizations from 60+ countries dedicated to studying and addressing the effects of global environmental change on human health.

This spring, Save Our Susquehanna (SOS), a grassroots group in central Pennsylvania, successfully halted Houston-based Encina’s proposed “chemical recycling” plant, one of the largest proposals in the nation.

On April 18, after two years of local opposition, Encina announced it would not proceed with the plant in Point Township, Pennsylvania. This decision marks a significant victory for Pennsylvanians, achieved through the determined efforts of SOS and support from The Climate Reality Project, Clean Air Council, GAIA, and Beyond Plastics. Read on to learn how local advocates united to defeat Encina’s proposal.

The American Chemistry Council promotes chemical recycling as a solution to plastic waste but this article highlights concerns raised by environmentalists about its efficacy and environmental impact, as well as the lobbying efforts to reclassify it as manufacturing in 24 states.

This article discusses the latest update to the planetary boundaries model, highlighting the inclusion of numerical guideposts for each boundary and emphasizing the interconnected factors influencing Earth’s habitability beyond climate change.

In this study several commercial paints were analyzed for volatile and nonvolatile per- and polyfluoroalkyl substances (PFAS), finding that paints could be potential sources of human exposure to PFAS, with one paint exceeding the reference dose for children and adults.

Who do you think would win at the sustainability tug-o-war? Team safer materials or team low-carbon products?

Healthy Building Network (HBN) has often heard these two issues framed as a competition–a false choice. Instead, we know that these two powerhouses must work together for optimal results.

In 2022, HBN and Perkins & Will published a study highlighting building products that can do just that: optimize material health and lower their carbon footprint. This study identified key drivers and paths towards low embodied carbon and safer materials as well as when to consider and optimize both at the same time. To illustrate this point, we plotted an actionable path for project teams using flooring products as an example.

Team Low-Carbon Products: The embodied carbon of building materials contribute a whopping 11% to global carbon emissions.1 Most of these emissions happen before that product even gets installed. Additionally, the poorest countries and regions are those most impacted in terms of damage and loss of life by the effects of climate change.2 “That 11% might sound small compared with the impact of operational energy (28%), but for new construction, embodied carbon matters just as much as energy efficiency and renewables. That’s because the emissions we produce between now and 2050 will determine whether we meet the goals of the 2015 Paris climate accord and prevent the worst effects of climate change,” explains a BuildingGreen report

Team Safer Materials: We spend 90% of our time indoors, and hundreds of industrial chemicals are found in our indoor spaces— in the dust, in the air we breathe, and in our bodies.3 The health impact of building materials are not limited to their time in use in the building, they often occur during manufacturing, installation, and at the product’s end of life. People living in close proximity to industrial facilities experience persistently worse air quality than average and exposure to industrial pollutants disproportionately impacts people of color.4 Another report suggests man-made pollution has exceeded the Earth’s safe operating boundaries.5 “Transgressing a boundary increases the risk that human activities could inadvertently drive the Earth System into a much less hospitable state, damaging efforts to reduce poverty and leading to a deterioration of human wellbeing in many parts of the world, including wealthy countries.” Professor Will Steffen, researcher at the Centre and the Australian National University, Canberra.6

Reducing toxic chemical use and the emissions associated with building materials NOW is a vital sustainability strategy for any project team.

The Research: 

To identify the key drivers of embodied carbon and the key opportunities to reduce embodied carbon for each product type we read Environmental Product Declarations (EPDs), reviewed literature and data compilations, and conducted manufacturer interviews. The hazards associated with flooring products, the chemicals used to make those materials and the hazards associated with the chemicals used to install those products were collected using InformedTM product guidance and hazard data in the Pharos database

Embodied Carbon:

 Our research concluded that flooring products’ embodied carbon impacts are mostly associated with the raw material supply. The biggest opportunities to reduce embodied carbon in flooring comes from choosing a different product type that uses less impactful raw materials as well as products with longer service life. Carpet was consistently the most impactful product type due in part to its short service life. Plant-based flooring products, such as wood and natural cork, were consistently the least impactful.

Material Health:

 Not surprisingly, the biggest opportunities to avoid chemicals of concern in flooring come from choosing a product type with typically fewer chemicals of concern. Products made from plastic, such as vinyl, nylon, or polyurethane tend to use more hazardous chemicals during manufacturing, installation, use, and end of life, than mineral or plant-based products. Selecting a product that is yellow or above in InformedTM color ranking Flooring Guidance, such as wood or linoleum, or even a non-vinyl resilient flooring will minimize the use of hazardous chemicals. Products in the red zone such as vinyl and carpet, should be avoided.

Conclusion: 

When we looked at the opportunities to improve embodied carbon and improve material health for flooring we found that they were largely complementary.

  • Use flooring with a long service life. Avoid products with a short service life, like carpet, and select a product with a long service life, like wood. 
  • Choose biobased product types. Linoleum, wood, and cork are all flooring product types that were identified as both resulting in lower embodied carbon and safer in terms of material health. 
  • If you must use carpet, avoid use of virgin nylon carpet product types. While carpet generally can contain more chemicals of concern than other product types, carpet made with virgin nylon as a generic product type was identified as having the highest embodied carbon within the flooring category. 
  • Use circular and safe materials. Use recycled content from known sources. Prefer products that have been tested for these chemicals and have below detectable levels or below levels that would be found in virgin resin content for these materials. 

These findings highlight the importance of pre-emptive design.  Parallel to the way we conduct early modeling for energy or water use, the industry needs to model for embodied carbon and material health. A materials modeling approach–where the entire team is engaged early – before design development or construction development – will enable educated decisions before the design is set.  Use HBN’s Embodied Carbon and Material health in Flooring and Drywall report and tools like Informed™ and the Carbon Smart Materials Palette to select typically healthier, low-carbon building product options.
