Vietnam cement EPD disclosures: 135 products but only 6 firms, and no national standard yet

Vietnam's cement industry is starting to publish Environmental Product Declarations (EPDs), but the numbers show how early the transition is. Only 135 cement and clinker products from six companies have disclosed their carbon footprint, led by Vicem Ha Tien with 51 products. The average clinker emission rate is 0.91 tons of CO2 per ton, with limestone decomposition and fuel combustion in the kiln responsible for the vast majority of emissions. The article from Vietnam.vn highlights a major obstacle: the country lacks its own EPD standard system and a domestic certifier recognized internationally. That makes it harder for more producers to participate and for export buyers to verify the data. With cement production around 126 million tons of capacity and exports at 21.77 million tons in 2025, the sector faces real pressure to standardize carbon reporting. For anyone tracking low-carbon construction materials or carbon disclosure policy, this is a useful snapshot of where Vietnam's cement industry stands. The gap between a few pioneers and the rest of the industry is the story.

Only 6 companies out of the whole industry means the EPD numbers are still a drop in the bucket. Good to see the data, but the real test is whether buyers start demanding it.

0.91 tons CO2 per ton of clinker is the average. That is heavy. The breakdown shows limestone calcination does most of the damage, so cutting clinker ratio in cement is the obvious lever.

They mention cement grinding only 4.4% of emissions. That makes sense since it is mostly electricity. So decarbonizing the grid helps a bit, but the kiln is the hard part. Need alternative fuels and process heat solutions.

Vietnam has no domestic EPD standard or certifier. That is a big gap if they want export markets to take these declarations seriously. International buyers will ask questions.

The policy question is how to make EPD adoption cheaper and mandatory. Right now six firms volunteering is not a market signal. If green public procurement requires EPDs, more companies will follow.

For construction materials, the clinker content matters. Domestic cement at 70% clinker emits 0.65 tCO2/t, export at 90% emits 0.82. Blended cement is a practical way to cut embodied carbon without new kilns.
