Federal Incentives and Policy Drivers for Type IL Cement
During 2019–2024, multiple federal actions incentivized the cement industry’s shift to Type IL (Portland-Limestone Cement). Congressional legislation explicitly promoted lower-carbon materials. For example, PCA President Mike Ireland noted that the 2022 federal infrastructure and climate laws included “millions of dollars in environmental provisions that specifically call for the use of lower-carbon cements in government construction.” These provisions came through bills like the Bipartisan Infrastructure Law (2021) and the Inflation Reduction Act (2022), which funded “Buy Clean” procurement programs favoring low-embodied-carbon cement and concrete.
In November 2023, the U.S. General Services Administration (GSA) announced $2.15 billion for low-carbon material procurement (with ~$767 million earmarked for low-carbon concrete) under the Inflation Reduction Act. PCA actively engaged with GSA in shaping these requirements – “PCA engaged GSA on specific things that should be taken into consideration… which resulted in more appropriate global warming potential limits for cements,” according to a PCA briefing. In other words, PCA worked with federal officials to ensure the new “green” procurement rules were achievable with Type IL cement, positioning it as the compliant solution.
Beyond procurement, federal agencies offered direct funding to cement producers to cut emissions. In 2024, the U.S. Department of Energy (DOE) awarded over $1.2 billion (via the infrastructure law and IRA) to four PCA member companies for carbon-capture and low-carbon cement projects. Ireland welcomed this DOE funding, calling it “a welcome acknowledgement from the government that America’s cement manufacturers are taking ambitious steps toward reaching carbon neutrality.” This federal support aligned with PCA’s “Roadmap to Carbon Neutrality” and validated the industry’s environmental messaging – while also subsidizing technologies that can protect cement plants’ future profitability.
Regulatory developments also nudged PCA’s promotion of Type IL. The EPA and DOT moved toward climate-focused standards, creating an opening for PCA to champion Portland-limestone cement as a ready solution. By May 2022, 44 state Departments of Transportation had approved the use of Type IL cement in infrastructure, after testing its performance. PCA applauded this milestone, touting PLC’s “CO₂ footprint up to 10% lower” than ordinary cement.
By April 2024, all 50 states and D.C. accepted Type IL, which “coincides with growing cement consumption by state transportation departments, fueled by the Bipartisan Infrastructure Law.” In PCA’s eyes, federal infrastructure spending and procurement rules clearly incentivized switching to Type IL – an ostensibly environmental move that also expanded market demand for the industry’s new product.
PCA’s Engagement with Government Officials and Politicians
The Portland Cement Association closely coordinated with policymakers through this period, often framing Type IL cement as a win-win for climate and construction. PCA organized annual “fly-in” lobbying events in Washington, D.C., bringing cement executives to meet with Members of Congress and agency leaders.
For instance, the 3rd Annual Cement & Concrete Fly-In in April 2019 (held in D.C.) highlighted industry sustainability efforts. “The awards highlight how America’s cement manufacturers are focused on sustainably producing the highest quality product with minimal environmental footprint,” said PCA CEO Mike Ireland at that 2019 event. (Those Energy & Environment awards were literally presented at the fly-in on Capitol Hill, underscoring PCA’s strategy of showcasing “green” practices to policymakers.)
By 2024, these fly-ins explicitly centered on pushing lower-carbon cement and easing regulations. In June 2024, Ireland led a record delegation of cement CEOs to Capitol Hill to discuss decarbonization – and to ask for regulatory relief. “There’s a lot happening in Washington this year that directly impacts America’s cement manufacturers… Our industry’s top objective is to reach carbon neutrality,” Ireland stated, while cautioning that “unrealistic EPA regulations” and a “cumbersome permitting system” hinder progress. He noted companies “appreciate recent funding from the DOE to assist in decarbonization efforts” but warned Congress that new air rules could force cuts in plant operations.
As federal infrastructure funds ramped up construction, “the country needs more cement and concrete, not less,” Ireland argued, urging lawmakers to “work with us to arrive at reasonable policies and standards” that would allow continued production of “resilient, sustainable” materials. This direct plea shows PCA leveraging environmental goals (carbon neutrality) to seek favorable treatment – essentially asking politicians to promote Type IL cement usage in public projects while scaling back regulations that might hurt profitability.
PCA also interfaced with the executive branch. In late 2021, Ireland explicitly called on government agencies to promote Type IL cement: “It is vital for the government to promote the use of Portland-limestone cement (PLC). This is a concrete mix that reduces emissions 10%, and at a competitive cost… [States] should also promote it for use in the many major infrastructure projects to come.” This statement, published just after the 2021 infrastructure bill, reveals PCA’s strategy – get federal and state officials to specify Type IL cement in projects for quick climate wins.
The key phrase “at a competitive cost” hints at one motivation: PLC offers environmental benefit without higher expense. In fact, PCA’s advocacy materials repeatedly emphasize “market-based solutions”. The association’s policy stance is to cut carbon “while preserving [the industry’s] global competitiveness.” In practice, PCA worked hand-in-hand with officials to bake Type IL into procurement standards and to secure “favorable policies and funding for the use of alternative cements” under federal programs. This collaborative lobbying ensured that environmental initiatives like Buy Clean were shaped in ways that helped cement manufacturers capture lucrative government contracts.
PCA Leadership’s Statements on the Shift to Type IL
Public remarks by PCA leaders from 2019–2024 consistently portray the transition to Type IL cement as an environmental innovation. Mike Ireland, PCA’s CEO, was the chief spokesperson. When PCA launched a major PLC promotion campaign in October 2020, Ireland framed it as the industry “continuing to innovate” for sustainability: “PLC is another example of the cement industry evolving… sustainably producing the high-quality cement that is needed to help keep America’s infrastructure strong and resilient.”
That campaign included a new microsite (GreenerConcrete.com) with case studies and a carbon-footprint calculator to evangelize PLC’s benefits. Ireland said the initiative would “educate engineers and other specifiers on how PLC can easily be incorporated into numerous projects” – stressing that using Type IL is an easy, drop-in substitution for ordinary cement (a point PCA often made to quell concerns).
As the market rapidly adopted PLC, Ireland highlighted the environmental impact. In a January 2024 newsletter, he noted that by mid-2023 “the market share for blended cements was 54.5%, and PLC’s share of blended cement was 95%… In other words, PLC is becoming the new norm in American concrete construction.” He touted that “the U.S. avoided more than 1.8 million metric tons of CO₂ in 2022 using PLC and other blended cements.”
Ireland’s messaging to industry peers reinforced that “PLC—when used properly—is just as durable, strong, and resilient as Portland cement, but with the added benefit of a smaller carbon footprint.” These statements show PCA’s leaders aligning the sustainability narrative (carbon reduction, no performance trade-offs) to build confidence in Type IL among engineers, contractors, and regulators.
Notably, PCA credited government action for accelerating this shift. In that same 2024 memo, Ireland praised the fact that “46 State DOTs have now approved [PLC’s] use” and directly linked it to federal support: “In 2022, Congress passed groundbreaking legislation… specifically calling for the use of lower-carbon cements.” Such remarks indicate PCA’s leadership was openly acknowledging and thanking policymakers for helping make PLC the industry standard. It suggests a coordinated effort: PCA members invested in producing PLC, while PCA lobbyists and allies in government cleared the path by updating standards and allocating funding to favor this “greener” cement.
Environmental Justification vs. Financial Benefits to Manufacturers
While PCA’s public rationale centered on environmental benefits, evidence suggests this green push also aligned with significant financial and operational advantages for cement manufacturers. Portland-limestone cement’s chemistry is straightforward: by inter-grinding up to 15% uncalcined limestone into cement (instead of clinker), CO₂ emissions per ton are about 10% lower. Crucially, this also means using less energy-intensive clinker per ton of cement, which lowers production costs.
Industry experts point out that “using Type IL cement can potentially lead to cost savings due to the reduced clinker content and the associated lower energy consumption during production.” In short, making PLC requires less fuel and raw material per ton of finished cement – a clear economic win for producers. PCA and its members seldom advertise this profit motive, but it underlies their enthusiasm: PLC allows companies to stretch clinker supplies (in effect, raising output by up to ~10% without new kilns) and cut fuel costs, all while selling cement at traditional prices.
The “competitive cost” Ireland mentioned is telling. For consumers and government buyers, PLC is priced similarly to ordinary cement (sometimes even at a slight discount), removing any cost barrier to adoption. For manufacturers, however, the absence of a price premium combined with lower production costs can improve margins or at least maintain them. The Engineering News-Record, reporting on the PLC trend, noted that it “does not sacrifice performance or affordability in comparison with its predecessor. That has made it a relatively straightforward alternative to the higher-carbon version.”
In other words, switching to PLC lets producers claim sustainability gains “without increasing costs” to customers – an ideal scenario for industry acceptance. It also helps insulate the sector from more aggressive climate policies: by voluntarily reducing CO₂ 10% via PLC, cement companies can argue they are doing their part, potentially heading off stricter regulation or carbon pricing that would be costlier. This dynamic led some observers to suggest the environmental narrative doubled as a convenient business strategy. PCA itself emphasizes “market-based policies” and avoiding “regulatory burdens,” indicating a preference for solutions like PLC that cut emissions but also protect the bottom line.
Internal statements or candid admissions of profit motivation are hard to come by in public sources, as PCA understandably keeps messaging positive. However, the coordinated lobbying efforts and rapid industry-wide implementation of Type IL cement reveal the underlying calculus. PCA’s advocacy documents make clear that the goal is to reduce carbon “while preserving…competitiveness” – essentially, to decarbonize in ways that don’t hurt profits.
Promoting Portland-limestone cement fit this formula perfectly. It gave the industry a “green” credential (lower embodied CO₂) to meet the demands of an “environmentally aware America” and comply with new federal mandates, all with minimal disruption to production or sales. Indeed, PCA hailed PLC as “an easy transition with simple modifications to existing specifications” – no expensive retooling needed. Compared to truly cutting emissions (e.g. by installing carbon capture or switching to alternative binders), PLC was a relatively low-cost change that could be scaled up quickly and even yield efficiency gains.
Meetings and Communications Pointing to the True Motives
The record of PCA meetings and communications from 2019–2024 supports the view that environmental benefits and profit motives went hand-in-hand in the Type IL campaign. PCA’s outreach to officials often stressed sustainability, but also consistently sought taxpayer-funded support and regulatory flexibility that benefit manufacturers’ finances.
For example, in PCA’s June 2024 Congressional meetings, Ireland balanced his “carbon neutrality” talking points with requests to ease EPA rules that “could lead to…cuts in plant operations and staffing.” He explicitly tied the need for more cement production to the booming federally funded infrastructure market – reinforcing that industry revenue (supplying all those projects) should not be jeopardized by overzealous regulation.
In PCA’s November 2023 update on GSA’s low-carbon projects, the association proudly noted influencing the GWP limits for cement – a behind-closed-doors negotiation ensuring that most Portland-limestone cement would qualify for federal contracts. This is a clear instance of PCA working with federal officials to secure a market advantage under the guise of meeting climate goals.
Even PCA’s sustainability roadmap and partnerships reveal an element of self-interest. The association promoted PLC as one piece of a broader climate strategy that also calls for government incentives. In PCA’s own words, many roadmap actions “need policy support.” Among these, PCA has been “vocal on… [driving] market acceptance of low-carbon alternative cements such as Portland-limestone cement.” Thanks to PCA’s lobbying, by 2023 the federal government was actively encouraging or mandating PLC use in public works, creating a captive market for cement companies that had shifted to Type IL.
