Companies, organizations, and firms working in the building, construction, and design space have a unique opportunity and responsibility. Collectively, we are contributing to nearly 40% of energy-related carbon emissions worldwide. While the goals, commitments, pledges, and promises around these challenges are a step in the right direction, no one entity alone will make major improvements to this daunting issue.

We need to come together, demonstrate courageous change leadership, and take collective approaches to address the built environment's impacts on climate. Collectively, we have a unique opportunity to improve people's lives and make positive, measurable changes to impact:

  • Buildings, homes, and hardscapes

  • Community planning

  • Consumer, commercial, and public sector behavior

Our Collective Challenge to Reduce our Carbon Footprint

According to many sources, including the U.S. Green Building Council (USGBC), the built environment accounts for 39% of global energy-related carbon emissions worldwide. Operational emissions from buildings make up 28% and the remaining 11% comes from materials and construction.

By definition, embodied carbon is emitted by the manufacture, transport, and installation of construction materials, and operational carbon typically results from heating, cooling, electrical use, and waste disposal of a building. Embodied carbon emissions are set during construction. This 11% of carbon attributed to the building materials and construction sector is something each company could impact individually based on manufacturing processes and material selection.

The more significant 28% of carbon emissions from the built environment is produced through the daily operations of buildings. This is a dynamic that no company can influence alone. Improving the energy performance of existing and new buildings is a must, as it accounts for between 60–80% of greenhouse gas emissions from the building and construction sector. Improving energy sources for buildings, and increasing energy efficiency in the buildings' envelope and operating systems are all necessary for future carbon and economic performance.

Why It Is Imperative to Reduce our Carbon Emissions Today

There are numerous collectives that are driving awareness, understanding, and action at the governmental and organizational levels, largely inspired by the Paris Agreement enacted at the United Nations Climate Change Conference of Parties (COP21) in 2015. The Architecture 2030 Challenge was inspired by the Paris Agreement and seeks to reduce climate impacts from carbon in the built environment.

Since the enactment of the Paris Agreement and Architecture 2030 Challenge, myopic approaches to addressing carbon have prevailed, including the rampant net-zero carbon goals for individual companies, firms, and building projects. Though these efforts are admirable, many lack real roadmaps to achieve these goals. In light of this, the US Security and Exchange Commission has issued requirements for companies, firms, and others to divulge plans to meet these lofty goals and ultimately report to the government on progress in reaching targets. These individual actions will only take us so far.

Additionally, the regulatory environment continues to evolve and drive change. If we consider the legislative activity in Europe, which frequently leads the way for the rest of the world, we can all expect carbon taxes to become the standard. There are currently 15 proposed bills that would implement a price on carbon dioxide emissions. Several states have introduced carbon pricing schemes that cover emissions within their territory, including California, Oregon, Washington, Hawaii, Pennsylvania, and Massachusetts. Currently, these schemes primarily rely on cap and trade programs within the power sector. It is not a matter of if but when carbon taxes will become a reality in the US.

Theory of Change

Climate issues are immediate and immense. Our industry is so interdependent that we can't have one sector delivering amazing results while another is idle. Making changes and improvements requires an effort bigger than any one organization could manage. Working together, we can share resources and ideas in new ways. We can create advantages and efficiencies in shared R&D, supply chain, manufacturing, transportation, design, installation, and more.

Collaboration will bring measurable near-term positive change that would enable buildings and homes to become net-positive beacons for their surrounding communities. We can create a network where each building/home has a positive multiplier effect. The network is then compounded by linking to other elements that contribute to a community's overall carbon footprint.

Proof of Concept: GAF Cool Community Project

An estimated 85% of Americans, around 280 million people, live in metropolitan areas. As the climate continues to change, many urban areas are experiencing extreme heat or a "heat island effect." Not only is excess heat uncomfortable, but heat islands are public health and economic concerns, especially for vulnerable communities that are often most impacted.


Pacoima, a neighborhood in Los Angeles, was selected by a consortium of partners as a key community to develop a first-of-its-kind community-wide research initiative to understand the impacts various cooling solutions have on urban heat and livability. Pacoima is a lower income community in one of the hottest areas in the greater Los Angeles area. The neighborhood represents other communities that are disproportionately impacted by climate change and often underinvested in.

Implementation:

Phase 1: This included the application of GAF StreetBond® DuraShield cool, solar-reflective pavement coatings on all ground-level hard surfaces, including neighborhood streets, crosswalks, basketball courts, parking lots, and playgrounds. The project also includes a robust community engagement process to support local involvement in the project, measure qualitative and quantitative impact on how cooling improves living conditions, and ensure the success of the project.

Phase 2: After 12 months of monitoring and research, GAF and partners will evaluate the impact of the cool pavements with the intent to scale the plan to include reflective roofing and solar solutions.

This ongoing project will allow us to evaluate for proof of concept and assess a variety of solutions as well as how different interventions can work together effectively (i.e., increasing tree canopies, greenspacing, cool pavements, cool roofs, etc.). Through community-wide approaches such as this, it's possible that we could get ahead of the legislation and make significant innovative contributions to communities locally, nationally, and globally.

GAF Is Taking Action to Create Community-wide Climate Solutions

With collaboration from leaders across the building space and adjacent sectors, we believe it is possible to drive a priority shift from net neutral to net positive. Addressing both embodied and operational carbon can help build real-world, net-positive communities.

We invite all who are able and interested in working together in the following ways:

  • Join a consortium of individuals, organizations, and companies to identify and develop opportunities and solutions for collective action in the built environment. The group will answer questions about how to improve the carbon impacts of the existing and future built environment through scalable, practical, and nimble approaches. Solutions could range from unique design concepts to materials, applications, testing, and measurement so we can operationalize solutions across the built environment.

  • Help to scale the Cool Community project that was started in Pacoima. This can be done by joining in with a collaborative and collective approach to climate adaptation for Phase 2 in Pacoima and other cities around the country where similar work is beginning.

  • Collaborate in designing and building scientific approaches to determine effective carbon avoidance—or reduction—efforts that are scalable to create net-positive carbon communities. Explore efforts to use climate adaptation and community cooling approaches (i.e., design solutions, roofing and pavement solutions, improved building envelope technologies, green spacing, tree coverage, and shading opportunities) to increase albedo of hard surfaces. Improve energy efficiency to existing buildings and homes and ultimately reduce carbon at the community level.

How GAF's Co-Op Program Makes a Difference in Students' Lives

As part of its effort to build resilient communities, GAF provides students across the country with opportunities to gain work experience and hands-on training. The GAF co-op program offers participants autonomy and leadership in project management, engineering design, budgeting, project installation, and more.Over the years, the GAF co-op recruiting program has helped students advance academically, grow professionally, and earn competitively while working full time with North America's largest roofing and waterproofing manufacturer.How the GAF Co-Op Program WorksThe program gives students high-impact, hands-on experience in the manufacturing sector. They perform meaningful work alongside supportive GAF mentors and senior leadership while earning a competitive wage. Participants can also receive credits from their university, which they can apply to their coursework.Differences between a Co-op and an InternshipInternships and co-ops have a few notable differences. At GAF, the main difference is the length of time. Internships at GAF usually last 10 weeks, but the co-op program is six months. While internship programs often allow students to stay enrolled in school and complete coursework as they gain professional training, co-op participants must take a semester off to gain full-time work experience.Not all companies pay internship participants for their work. However, at GAF, both interns and co-op students are paid competitive hourly wages. GAF also offers financial relocation assistance for qualifying co-op program candidates.Finally, participants in the GAF programs are there to learn real skills that will help them advance their future careers. GAF interns and co-op students are given the same responsibilities, and chances to collaborate on major projects, as full-time employees.Recent GAF Co-Op Success StoriesMin U, a mechanical engineering student at the University of Maryland, says he "fell in love with manufacturing" thanks to his placement on an engineering project. The experience gave him a firsthand account of the role engineering plays in manufacturing safety, profit, and operations. This ultimately led him to shift his career goals from construction management to manufacturing engineering.When Dante Stellar, an industrial engineering student at Virginia Tech, met GAF representatives at a career fair, he says he didn't expect to become a self-proclaimed "nerd for shingles" and develop a passion for manufacturing. However, that's exactly what happened. And that newfound passion paid off when Dante won Student of the Year from Virginia Tech's Cooperative Education and Internship Program. Dante notes he's now eager to return to GAF and aspires to become a manufacturing leader in the world of shingles.Michael Hesseltine, an electrical engineering student at Texas A&M University, chanced upon a GAF co-op recruiting listing online. After a series of interviews, he landed a project engineering co-op in Ennis, Texas. Working with the Ennis team on major projects solidified his manufacturing engineer career goals.Co-Op Students Complete Meaningful WorkStudents in the GAF co-op program are involved in meaningful projects and get to see their work's impact on day-to-day operations.During his time in Ennis, Michael designed a baler that compacts fiberglass scrap, reducing site disposal trips and costs. He also oversaw renovations of the site's maintenance mechanical break room from start to finish. He notes that his favorite contribution was helping design the electrical system for a dewatering press.In Baltimore, Min's core project was ensuring site compliance with state regulations for discharging stormwater runoff. Min managed all the project contractors and budget with his manager's and mentor's support. Throughout his time there, Min was exposed to Lean methodologies, 5S, risk mitigation, insurance compliance, cost control, and procedure standardization. He gained an overall understanding of manufacturing equipment and business.At the Tampa plant, Dante worked on a rock pad storage expansion project and installed a starwheel machine guarding the manufacturing line, among other important projects. According to Dante, the defining moment of his co-op experience was his granule silo refurbishment project, which involved replacing eight silos, including floor plates and support beams.Dante explains the trust and opportunities his mentors provided were key to his success. "At GAF, I was given the chance to interact with contractors, and immerse myself in the plant, which accelerated my learning," he says.Co-Op Students Build Professional RelationshipsThrough "lunch and learn" sessions, leadership speaker series, meetings with senior leadership, and mentorship, co-op students build long-term professional relationships.Dante was given the chance to showcase the coordination and safety efforts involved in his granule silo project to the GAF executive leadership team in Parsippany, New Jersey.For Min, getting the right feedback to grow meant having the right relationships. He notes the mentorship from his manager Alex Smith and engineering manager Mike Kloda was key to his progression. As advice to future co-op participants, he explains that "everyone is here to help... but it's up to you to drive that forward."Meanwhile, the autonomy and leadership opportunities program leaders gave Michael allowed him to grow technically and professionally. "I was often the go-to person for projects, managing contractors and ensuring everything was on track," he says.Joining an Industry Filled with OpportunityThe GAF co-op program helped Min, Michael, and Dante start and solidify their careers in manufacturing engineering. Following their experience, each student was excited and motivated by the autonomy, responsibility, and growth opportunities they were given. In fact, Min has since accepted a full-time role as a project engineer at the GAF plant in Baltimore. His expected start date is July 7, 2025.GAF is committed to fostering diversity, equity, and inclusion throughout the organization. It believes a talented and diverse organization can drive innovation, growth, and transformation more effectively. To further bolster inclusivity, GAF offers academic and merit scholarships, partners with the Thurgood Marshall College Fund to recruit from the nation's most diverse talent at Historically Black Colleges and Universities and Predominantly Black Institutions, and reaches out to candidates at career fairs nationwide.Bright and motivated minds who want to explore manufacturing have plenty of opportunities. From shingles to solar to environmental impact, GAF offers many exciting career paths.Are you ready to do work that matters and be empowered to explore a leadership role?

Roof Insulation: A Positive Investment to Reduce Total Carbon

Have you ever thought about building products reducing the carbon dioxide emissions caused by your building? When considered over their useful life, materials like insulation decrease total carbon emissions thanks to their performance benefits. Read on for an explanation of how this can work in your designs.What is Total Carbon?Total carbon captures the idea that the carbon impacts of buildings should be considered holistically across the building's entire life span and sometimes beyond. (In this context, "carbon" is shorthand for carbon dioxide (CO2) emissions.) Put simply, total carbon is calculated by adding a building's embodied carbon to its operational carbon.Total Carbon = Embodied Carbon + Operational CarbonWhat is Embodied Carbon?Embodied carbon is comprised of CO2 emissions from everything other than the operations phase of the building. This includes raw material supply, manufacturing, construction/installation, maintenance and repair, deconstruction/demolition, waste processing/disposal of building materials, and transport between each stage and the next. These embodied carbon phases are indicated by the gray CO2 clouds over the different sections of the life cycle in the image below.We often focus on "cradle-to-gate" embodied carbon because this is the simplest to calculate. "Cradle-to-gate" is the sum of carbon emissions from the energy consumed directly or indirectly to produce the construction materials used in a building. The "cradle to gate" approach neglects the remainder of the embodied carbon captured in the broader "cradle to grave" assessment, a more comprehensive view of a building's embodied carbon footprint.What is Operational Carbon?Operational carbon, on the other hand, is generated by energy used during a building's occupancy stage, by heating, cooling, and lighting systems; equipment and appliances; and other critical functions. This is the red CO2 cloud in the life-cycle graphic. It is larger than the gray CO2 clouds because, in most buildings, operational carbon is the largest contributor to total carbon.What is Carbon Dioxide Equivalent (CO2e)?Often, you will see the term CO2e used. According to the US Environmental Protection Agency (EPA), "CO2e is simply the combination of the pollutants that contribute to climate change adjusted using their global warming potential." In other words, it is a way to translate the effect of pollutants (e.g. methane, nitrous oxide) into the equivalent volume of CO2 that would have the same effect on the atmosphere.Today and the FutureToday, carbon from building operations (72%) is a much larger challenge than that from construction materials' embodied carbon (28%) (Architecture 2030, 2019). Projections into 2050 anticipate the operations/embodied carbon split will be closer to 50/50, but this hinges on building designs and renovations between now and 2050 making progress on improving building operations.Why Insulation?Insulation, and specifically continuous insulation on low-slope roofs, is especially relevant to the carbon discussion because, according to the Embodied Carbon 101: Envelope presentation by the Boston Society for Architecture: Insulation occupies the unique position at the intersection of embodied and operational carbon emissions for a building. Insulation is the only building material that directly offsets operational emissions. It can be said to pay back its embodied carbon debt with avoided emissions during the building's lifetime.A Thought Experiment on Reducing Total CarbonTo make progress on reducing the total carbon impact of buildings, it is best to start with the largest piece of today's pie, operational carbon. Within the range of choices made during building design and construction, not all selections have the same effect on operational carbon.When making decisions about carbon and energy reduction strategies, think about the problem as an "investment" rather than a "discretionary expense." Discretionary expenses are easier to reduce or eliminate by simply consuming less. In the example below, imagine you are flying to visit your client's building. Consider this a "discretionary expense." The input on the far left is a given number of kilograms of carbon dioxide equivalent (CO2e) generated for the flight, from the manufacturing of the airplane, to the fuel it burns, to its maintenance. The output is the flight itself, which creates CO2 emissions, but no durable good. In this case, the only CO2 reduction strategy you can make is to make fewer or shorter flights, perhaps by consolidating visits, employing a local designer of record, or visiting the building virtually whenever possible. Now consider the wallpaper you might specify for your client's building. It involves a discretionary expenditure of CO2e, in this case, used to produce a durable good. However, this durable good is a product without use-phase benefits. In other words, it cannot help to save energy during the operational phase of the building. It has other aesthetic and durability benefits, but no operational benefits to offset the CO2 emissions generated to create it. Your choices here are expanded over the previous example of an airplane flight. You can limit CO2 by choosing a product with a long useful life. You can also apply the three Rs: reduce the quantity of new product used, reuse existing material when possible, and recycle product scraps at installation and the rest at the end of its lifespan. In the final step in our thought experiment, consider the insulation in your client's building. As before, we must generate a certain amount of CO2e to create a durable good. In this case, it's one with use-phase benefits. Insulation can reduce operational energy by reducing heat flow through the building enclosure, reducing the need to burn fuel or use electricity to heat and cool the building. The good news is that, in addition to the other strategies considered for the flight and the wallpaper, here you can also maximize operational carbon savings to offset the initial embodied carbon input. And, unlike the discretionary nature of some flights and the often optional decision to use furnishings like wallpaper, heating and cooling are necessary for the functioning of almost all occupied buildings.Based on this example, you can consider building products with operational benefits, like insulation, as an "investment." It is appropriate to look at improving the building enclosure and understanding what the return on the investment is from a carbon perspective. As the comparison above demonstrates, if you have a limited supply of carbon to "invest", putting it into more roof insulation is a very smart move compared to "spending" it on a discretionary flight or on a product without use-phase carbon benefits, such as wallpaper.This means we should be careful not to measure products like insulation that save CO2e in the building use-phase savings only by their embodied carbon use, but by their total carbon profile. So, how do we calculate this?Putting It to the TestWe were curious to know just how much operational carbon roof insulation could save relative to the initial investment of embodied carbon required to include it in a building. To understand this, we modeled the US Department of Energy's (DOE) Standalone Retail Prototype Building located in Climate Zone 4A to comply with ASHRAE 90.1-2019 energy requirements. We took the insulation product's embodied energy and carbon data from the Polyisocyanurate Insulation Manufacturers Association's (PIMA) industry-wide environmental product declaration (EPD).To significantly reduce operational carbon, the largest carbon challenge facing buildings today, the returns on the investment of our building design strategies need to be consistent over time. This is where passive design strategies like building enclosure improvements really shine. They have much longer service lives than, for example, finish materials, leading to sustained returns.Specifically, we looked here at how our example building's roof insulation impacted both embodied and operational carbon and energy use. To do this, we calculated the cumulative carbon savings over the 75-year life of our model building. In our example, we assumed R-30 insulation installed at the outset, increased every 20 years by R-10, when the roof membrane is periodically replaced.In our analysis, the embodied CO2e associated with installing R-30 (shown by the brown curve in years -1 to 1), the embodied carbon of the additional R-10 of insulation added every 20 years (too small to show up in the graph), and the embodied carbon represented by end-of-life disposal (also too small to show up) are all taken into account. About five months after the building becomes operational, the embodied carbon investment of the roof insulation is dwarfed by the operational savings it provides. The initial and supplemental roof insulation ultimately saves a net of 705 metric tons of carbon over the life of the building.If you want to see more examples like the one above, check out PIMA's study, conducted by the consulting firm ICF. The research group looked at several DOE building prototypes across a range of climate zones, calculating how much carbon, energy, and money can be saved when roof insulation is upgraded from an existing baseline to current code compliance. Their results can be found here. Justin Koscher of PIMA also highlighted these savings, conveniently sorted by climate zone and building type, here.Support for Carbon Investment DecisionsSo how can you make sure you address both operational and embodied carbon when making "carbon investment" decisions? We've prepared a handy chart to help.First, when looking at lower-embodied-carbon substitutions for higher-embodied-carbon building materials or systems (moving from the upper-left red quadrant to the lower-left yellow quadrant in the chart), ensure that the alternatives you are considering have equivalent performance attributes in terms of resilience and longevity. If an alternative material or system has lower initial embodied carbon, but doesn't perform as well or last as long as the specified product, then it may not be a good carbon investment. Another consideration here is whether or not the embodied carbon of the alternative is released as emissions (i.e. as part of its raw material supply or manufacturing, or "cradle to gate" stages), or if it remains in the product throughout its useful life. In other words, can the alternative item be considered a carbon sink? If so, using it may be a good strategy.Next, determine if the alternative product or system can provide operational carbon savings, even if it has high embodied energy (upper-right yellow quadrant). If the alternative has positive operational carbon impacts over a long period, don't sacrifice operational carbon savings for the sake of avoiding an initial embodied product carbon investment when justified for strategic reasons.Last, if a product has high operational carbon savings and relatively low embodied carbon (lower-right green quadrant), include more of this product in your designs. The polyiso roof insulation in our example above fits into this category. You can utilize these carbon savings to offset the carbon use in other areas of the design, like aesthetic finishes, where the decision to use the product may be discretionary but desired.When designing buildings, we need to consider the whole picture, looking at building products' embodied carbon as a potential investment yielding improved operational and performance outcomes. Our design choices and product selection can have a significant impact on total carbon targets for the buildings we envision, build, and operate.Click these links to learn more about GAF's and Siplast's insulation solutions.

GAF Scaling Environmental Product Declarations—Publishes 21 EPDs

At GAF, we're serious about our sustainability promise: to protect what matters most, including our people, our communities, and our planet. We recently published 21 new GAF product-specific Environmental Product Declarations (EPDs) as one way we're delivering on that promise.EPDs are critical to improving green building solutions. These standardized and third-party-verified documents outline the environmental impacts associated with a building product's life cycle—from raw material extraction to end-of-life disposal or reuse. Through the EPD creation process, we have been advancing on our sustainability goals, demonstrating our commitment to the environment and our customers, and increasing product sustainability in the roofing industry.Here's a look at our most recent progress and what's expected to come.GAF Sustainability GoalsThe 21 new EPDs are an exciting milestone toward our GAF 2030 Planet Goals, which have four focus areas: increase product transparency, reduce carbon emissions, drive circularity in the roofing sector, and divert operational waste. By 2030, we plan to publish EPDs for our entire commercial and residential core product portfolio. As we've scaled the GAF EPD creation process, through extensive life cycle assessments across our portfolio, we better understand the environmental impact of each stage in our products' life cycles. This opens up internal and external sustainability opportunities as we learn from, and analyze, our life cycle assessment results.Evolving to Product-Specific Environmental Product DeclarationsRoofing has long relied on industry-wide EPDs created from aggregate product data. As a result, our architecture, engineering, and construction (AEC) community members have had fewer opportunities to make informed sustainability choices around roofing materials.According to several sources, the built environment accounts for 39% of global energy-related carbon emissions worldwide. Collectively, we as a roofing industry could help reduce this number by increasing our transparency documentation. With more product-specific Environmental Product Declarations, companies and customers can make more informed product sustainability decisions.And although GAF currently has the highest overall number of transparency documents for roofing materials in the industry, we know we also have an opportunity to grow.GAF Uses Life Cycle Assessments to ImproveWe review product Life Cycle Assessments (LCAs) to understand the environmental impact of each product's production stages, from raw material extraction to end-of-life. Then, we can use that information to identify areas of improvement and make informed decisions to reduce a product's environmental impact, resulting in a reduction in embodied carbon. The knowledge we gain from our LCAs creates the potential for product improvements and new innovations to help further our 2030 Planet Goals.Looking Toward 2030 and BeyondWe're working hard to continue leading the industry with transparency documentation such as EPDs, Health Product Declarations, and Declare Labels. But we're not stopping there.We're fostering collaboration in our broader building, construction, and design space to help reduce the built environment's total carbon emissions. At GAF, sustainability isn't checking a box. We believe in and champion protecting our homes and our planet. By changing how we do business, we hope to improve how builders can build and, ultimately, how our world lives.Empowering the AEC CommunityTransparency and product sustainability documentation help us all build a better world. We're committed to empowering designers, builders, architects, and engineers by providing information about the lifecycle and environmental impact of GAF products whenever possible.Explore some of our most recent EPDs below.Polyiso InsulationEnergyGuard™ Barrier.
