Carbon Capture for a Net Zero Future in Vietnam


Utilizing on the Direct Air Capture (DAC) technology, INTRACO looks for solutions that “capture carbon emissions in the air”, while keeping the operating and maintenance costs at $100/ton CO2 captured.


The Earth is already about 1.1°C warmer than it was in the late 1800s, and emissions continue to rise. According to the Paris Agreement, to keep the Earth's temperature at no more than 1.5°C, emissions need to be reduced by 45% by 2030 and to zero by 2050.


According to a report from the United Nations Framework Convention on Climate Change (UNFCCC), reducing carbon emissions is not enough, the world needs to develop technologies that remove carbon from the atmosphere to achieve net zero emissions (Net-Zero) in 2050.


How can we reduce CO2 level in the air in an efficient manner to support the Vietnamese government's Net-Zero 2050 program?

Join the Carbon Capture challenge for a Net Zero future!

INTRACO is an enterprise specializing in the development of projects on climate change and carbon emission reduction.

Currently, INTRACO has been implementing 21 projects in 5 countries including Vietnam, Laos, Cambodia, Philippines and Japan. In which, 19 projects focus on reducing Carbon (Carbon Reduction) and 2 projects on removing Carbon from the atmosphere (Carbon Removal).

What is Direct Air Capture (DAC)? DAC (Direct Air Capture) is a technology that uses chemical or physical processes to remove CO2 from the atmosphere. The CO2 can then be stored in underground reservoirs through secure geological sequestration or used to create new products such as building materials and low-carbon fuels.
