1. Introduction

The construction industry is one of the largest sources of greenhouse gas emissions, accounting for around 37% of total global CO₂ emissions (IEA, 2022). The expansion of Emissions Trading Systems (ETS) beyond the energy sector into carbon-intensive industries — including building materials and operational processes — is reshaping the entire cost structure and competitive strategies of the construction sector.

2. ETS and the Cost of Carbon

ETS establishes an emission cap and allocates allowances to companies. Those exceeding their quota must purchase additional credits, while those reducing emissions can sell their surplus.
This mechanism turns carbon into an economic cost and a tradable asset.

In the construction sector, this means that both embodied carbon (emissions embedded in materials) and operational carbon (emissions during building use) will directly influence pricing structures.

3. Impact on Building Materials

High-emission materials such as cement, steel, and glass will face significant cost pressures.
A recent study published in the Journal of Cleaner Production found that ETS implementation significantly increases the cost of carbon-intensive materials, forcing the construction sector to shift toward products with transparent Environmental Product Declarations (EPD) and lower Life Cycle Assessments (LCA).

4. Technological Innovation and Carbon Management

ETS serves as a major driver of technological innovation.
Research by ICAP (2018) demonstrates a strong correlation between ETS adoption and the rise in low-carbon technology patents.

In the construction context, this is reflected through accelerated investment in low-clinker cement, electric arc furnace (EAF) steel, material recycling, and resource-efficient design.

5. Data Transparency and MRV Systems

To participate in ETS, companies must implement Measurement, Reporting, and Verification (MRV) systems.
This structure closely aligns with existing green building certifications (LEED, BREEAM, LOTUS) and EPD frameworks.

Enterprises that have already adopted such systems will streamline ETS compliance while enhancing data transparency.
A study published by Springer (Li et al., 2023) emphasizes MRV as a foundational pillar for building carbon trading systems within the construction industry.

6. Linkage with Green Finance

International financial institutions such as IFC, ADB, and AIIB increasingly tie funding eligibility to emission transparency.
Thus, carbon transparency is not only a regulatory requirement under ETS but also a prerequisite for accessing green capital.

This trend strengthens the connection between carbon governance and financial competitiveness in the construction sector.

7. Outlook for Vietnam

Vietnam has begun the pilot phase of its domestic carbon market in 2025, with full operation expected by 2028 (Reuters, 2025).
The steel and cement industries will be the first to be affected, but the impacts will inevitably extend across the entire construction value chain — particularly as the EU’s Carbon Border Adjustment Mechanism (CBAM) applies to Vietnamese exports.

8. Conclusion

ETS is redefining how the construction industry operates: shifting from a cost model driven primarily by materials and labor to one shaped by carbon costs, transparent data, and low-carbon technologies.

Enterprises that proactively adopt LCA, EPD, and green certifications before ETS becomes mandatory will secure a sustainable competitive advantage — both in market positioning and financial access.
