The event marked the International Day for the Preservation of the Ozone Layer 2025 (September 16). Under the national plan for managing and phasing out ozone-depleting substances (ODS) and controlled greenhouse gases, Vietnam aims to reduce CO2 emissions by 11.2 million tons through 2045.

Vietnam is on the right track in implementing the Vienna Convention and the Montreal Protocol, said Le Cong Thanh, Deputy Minister of Agriculture and Environment.

“Vietnam has improved its policies and legal framework on ozone layer protection through the incorporation of relevant regulations into the 2020 Law on Environmental Protection and its implementing documents.”

“This provides a solid foundation for Vietnam to manage controlled substances more effectively and in a coordinated manner, while linking ozone protection goals with other national priorities such as greenhouse gas emissions management and the pursuit of green transition targets,” Thanh explained.

At the workshop, participants exchanged information on bilateral, multilateral, and public–private cooperation models in managing and phasing out ozone-depleting substances and greenhouse gases for sustainable development. They proposed various tools, technological solutions, and new initiatives to support this effort.

The Montreal Protocol is a landmark 1987 international treaty to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances.
