Vietnam is the first country within the INSEE Group to operate a carbon market.
On the last day of June 2026, Vietnam opened its first carbon exchange at the Hanoi Stock Exchange, marking a formal institutional commitment to the country's net-zero 2050 ambition. Among the earliest participants was INSEE Vietnam, a cement manufacturer that traded 510 emissions allowances on opening day — a quiet but deliberate act signaling that industry, not just policy, is beginning to price the cost of carbon into its future. In a sector long associated with heavy emissions, the gesture carries weight: it suggests that the architecture of a low-carbon economy is being built not only in law, but in the ledgers of those who pour its foundations.
- Vietnam's carbon exchange launched June 29 with real trades on day one, transforming a long-standing policy ambition into a functioning market mechanism.
- INSEE Vietnam moved swiftly, accounting for 510 of the 1,210 allowances traded on opening day — a visible stake in a market where hesitation carries its own signal.
- The company's cement already emits 33% less carbon than conventional Portland cement, giving it a structural advantage as regulatory pressure on the construction sector intensifies.
- Biodiversity commitments — including 48,000 trees planted near endangered crane habitats — reveal a corporate strategy that extends well beyond carbon accounting.
- Vietnam becomes the first country in the INSEE Group to operate a carbon market, positioning the local subsidiary as a test case and model for the wider organization.
- The carbon exchange is expected to sharpen competitiveness across Vietnam's construction sector, rewarding early movers and raising the cost of inaction for those who wait.
On June 29, Vietnam's carbon exchange opened at the Hanoi Stock Exchange — a formal marketplace for emissions allowances designed to anchor the country's commitment to net-zero by 2050. By the end of that first day, 1,210 allowances had changed hands. INSEE Vietnam, a subsidiary of Siam City Cement, accounted for 510 of them, representing 510 tonnes of CO₂ equivalent through a mix of purchases and sales. The decision to participate on day one was not incidental — it reflected how deeply the company has already restructured itself around lower-carbon production.
INSEE operates an integrated cement plant in Hon Chong, An Giang province, and has spent recent years redesigning its manufacturing around decarbonization. Its Power-S cement achieves a 33 percent reduction in emissions compared with conventional Portland cement, verified through life cycle assessment. In 2025, the company's average emissions across cement production stood at roughly 337 kilograms per tonne — well below the industry average. These gains came through clinker optimization, expanded use of alternative fuels and raw materials, and circular economy practices embedded across the value chain.
The company's environmental commitments extend beyond carbon. INSEE has pledged to achieve a net positive impact on biodiversity by 2030, and during 2024 and 2025 planted more than 48,000 trees near protected areas in the region — part of a habitat restoration effort for the eastern sarus crane, an endangered species. The work connects industrial production to ecosystem health in ways that reach past the factory boundary.
Dao Nguyen Khanh, INSEE Vietnam's head of Sustainability Development and Communications, described the carbon market participation as both a corporate milestone and a learning moment for the broader INSEE Group — Vietnam being the first country within it to operate such a market. After more than three decades in Vietnam, the company is positioning its carbon exchange activity as one more step in a long-term commitment to the country's low-carbon transition, and to keeping its construction sector competitive as 2050 draws closer.
On June 29, Vietnam switched on its carbon exchange, and within hours, a cement company called INSEE was among the first to buy and sell emissions allowances on the new platform. The exchange opened at the Hanoi Stock Exchange as a formal marketplace for trading carbon credits and allowances—a mechanism meant to help the country meet its commitment to reach net-zero emissions by 2050.
During that opening day, 1,210 emissions allowances changed hands across the market. INSEE, a subsidiary of Siam City Cement, accounted for 510 of those allowances through a combination of purchases and sales. In practical terms, that represented 510 tonnes of carbon dioxide equivalent. The company's willingness to participate on day one signals something about how seriously it takes the regulatory environment shifting around it, and how it sees the carbon market as integral to its future operations.
INSEE operates an integrated cement plant in Hon Chong, in An Giang province. The company has spent recent years rebuilding its production footprint around lower-carbon methods. Its Power-S cement product achieves a 33 percent reduction in carbon emissions compared with conventional ordinary Portland cement, measured through life cycle assessment. In 2025, INSEE's average emissions across its cement production stood at approximately 337 kilograms per tonne—well below the industry average for the same period. The company attributes this to clinker optimization, increased use of alternative energy sources, and wider adoption of circular economy practices in its manufacturing process.
The emissions reductions did not happen by accident. INSEE has invested in energy-efficient production technologies, expanded its use of alternative fuels and raw materials, and strengthened circular economy initiatives across its value chain. All of its cement products are now designed with lower embodied carbon baked into the formula from the start. This represents a deliberate strategic pivot: reducing greenhouse gas emissions has become a core business priority, not a compliance checkbox.
Beyond decarbonization, INSEE is also pursuing biodiversity conservation. The company has committed to achieving a net positive impact on biodiversity by 2030. During 2024 and 2025, it planted and handed over more than 48,000 trees around the Phu My Species and Habitat Conservation Area and the Hon Chong Landscape Protection Area. The trees are part of a habitat restoration effort for the eastern sarus crane, an endangered species. The work connects cement production to ecosystem health in a way that goes beyond the factory gate.
Dao Nguyen Khanh, head of Sustainability Development and Communications at INSEE Vietnam, framed the company's participation in the carbon exchange as both a corporate milestone and a learning opportunity for the broader INSEE Group. Vietnam, he noted, is the first country within the group to operate a carbon market. Khanh expressed confidence that the exchange would become an important driver of Vietnam's green transition and reinforce the company's long-term commitment to supporting the country's low-carbon economy.
INSEE has operated in Vietnam for more than three decades. The company continues to expand its portfolio of sustainable cement and construction materials while investing in technologies and operational improvements designed to reduce environmental impacts. The carbon market participation is positioned as another step in that direction—a way to strengthen both the competitiveness and sustainability of Vietnam's construction sector as the country moves toward its 2050 net-zero target.

The Hearth Conversation Another angle on the story
Why does it matter that INSEE was among the first to trade on this exchange? Couldn't any company have done it?
The timing signals something. On day one, when the rules are still settling and the platform is untested, you're taking a risk. INSEE chose to be visible, to participate immediately. That tells regulators and competitors that the company sees this as legitimate and necessary, not something to wait out.
The numbers seem modest—510 allowances out of 1,210 total. Is INSEE a major player in this market?
Not necessarily the largest, but significant enough to move the needle. What matters more is the signal: a major cement producer is engaging with carbon pricing as a real constraint on its business. That changes how the industry thinks about emissions.
The company talks a lot about trees and biodiversity. Is that genuine or marketing?
The numbers are concrete—48,000 trees planted in specific locations, tied to habitat restoration for an endangered crane. That's measurable. Whether it's marketing or genuine commitment, the work is real. The question is whether it's proportional to the emissions the company produces.
What does 337 kilograms of CO₂ per tonne of cement actually mean? Is that good?
It's below the industry average, which INSEE emphasizes. But cement is inherently carbon-intensive—the chemical process of making it releases CO₂. The real question is whether 337 is approaching the theoretical minimum, or whether there's still a long way to go.
Why would a company voluntarily trade away emissions allowances if it doesn't have to?
Because the market creates value. If you reduce emissions below your allowance, you can sell the surplus. INSEE is both buying and selling, which suggests it's optimizing—using the market to find the most efficient allocation of its carbon budget.
What happens next? Does this market actually change how Vietnam's cement industry operates?
That depends on whether the carbon price is high enough to force real change, and whether the government enforces the system. A market that's too cheap or too loose becomes theater. But if it works, companies will start competing on emissions efficiency the way they compete on cost.
