## Summary

[Vietnam](/en/entity/vietnam) opened Southeast Asia's first mandatory carbon exchange on June 29, launching a pilot trading system on the Hanoi Stock Exchange (HNX) with 110 industrial facilities covering thermal power, steel, and cement. The total allocation stands at 511.47 million tCO2e for 2025-2026. On the opening session, over 1,200 tCO2e changed hands at 130,000-136,000 VND per tonne (~$5.10-$5.35/tCO2e), thin volume but symbolically significant. Covered companies include Hoa Phat Group, Formosa Ha Tinh Steel, EVN, PV Power, and Vicem. Entities may offset up to 30% of their quota with carbon credits; no transaction fees apply during the pilot. The trading window runs to December 24, 2027, with a full mandatory system and auctioning from 2029. The legal basis is Decree 29/2026/ND-CP, Decision 263/QD-TTg, and Circular 48/2026/TT-BTC. Prime Minister Tran Hong Ha's February 9 decision set the June 29 launch date.

## The split

Vietnamese state media (VietnamPlus) and the government portal frame the exchange as a national milestone for the green transition. Independent mass-market daily Thanh Nien emphasises economic competitiveness and the "lever to accelerate the green economy" angle. International business press (Bloomberg, VIR) leads with company-level compliance obligations and the CBAM pressure that accelerated the timeline. Carbon Pulse and the GMK Center note that at ~$5/tCO2e, Vietnam's price is well below EU ETS levels (~€65) and China's (~$12), raising doubts about the signal strength needed to drive industrial decarbonisation. East Asia Forum published a March 2026 analysis warning of enforcement-capacity gaps and thin-liquidity risk, both partially confirmed by opening-session trading volumes.

## By the numbers

- 511.47 million tCO2e, total allowances for 2025-2026 (243M for 2025; 268M for 2026)
- 110, covered facilities at pilot launch (34 thermal power plants, 25 steel mills, 51 cement plants)
- 92, initial participating companies including Hoa Phat, Formosa Ha Tinh, EVN, PV Power, Vicem
- 30%, maximum offset through carbon credits
- 1,200+ tCO2e, first-day trading volume
- $5.10-$5.35, approximate price range per tCO2e (130-136K VND) in the first session
- 2029, start of full mandatory system with auctioning

## Why it matters

Southeast Asia as a bloc has lagged on carbon pricing, and Vietnam's launch is the first mandatory mechanism in the region. The EU's Carbon Border Adjustment Mechanism (CBAM), which starts covering Vietnamese steel and cement exports by 2026, created a direct commercial incentive to establish a credible domestic price: a functioning ETS can offset CBAM charges, while no domestic price means full CBAM liability. The first-day price at ~$5/tCO2e signals the pilot's political nature ,  too low for meaningful abatement incentives, but it establishes infrastructure and precedent for the 2029 mandatory phase.

## What to watch

- Whether liquidity builds in the pilot phase or the market remains symbolic at sub-$10 prices.
- MRV enforcement: whether the Ministry of Agriculture and Environment can verify facility-level emissions against stated allocations.
- CBAM linkage: whether the EU accepts Vietnam's domestic carbon price as offsetting mechanism under Article 6 or bilateral arrangements.
- Whether Indonesia, Thailand, or other ASEAN members accelerate their own ETS timelines in response.

### Academic regional analysis; pre-launch sceptical take on enforcement and liquidity
- **East Asia Forum** (Australia / Regional, en) — March 2026 pre-launch analysis arguing Vietnam's carbon market faces a 'reality check' on enforcement capacity, data verification infrastructure, and the risk of thin pilot-phase liquidity that could undermine price signals. The first-day price around $5/tCO2e is well below EU ETS (~€65) and China's market (~$12), which the Forum flagged as a long-run challenge for industrial competitiveness.
