DATAM promotes a national joint project to achieve the Nationally Determined Contributions (NDC) by combining the Proof of Carbon Reduction (PCR) technology with sustainable domestic and foreign green technology to share technology with underdeveloped countries and developing countries, thereby improving the quality of human life, reducing fossil energy consumption and reducing greenhouse gas emissions. It was established to contribute to the response of the POST-2020 new climate system. DATAM is promoting the eco-friendly public transportation conversion project with the approval of the national project from the Laos government in January 2019. In June, DATAM is promoting the eco-friendly smart public transportation BRT system construction project that concluded an agreement with Ho Chi Minh City, the world's best traffic congestion city.
