1. What are Greenhouse Gases (GHG)?<\/b><\/span><\/h2>\n

Greenhouse gases are atmospheric gases that intercept long-wave (mainly infrared) radiation emitted from the Earth’s surface, then re-radiate in all directions including back to Earth, causing the greenhouse effect. Major greenhouse gases include water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), trioxygen (O3) and chlorofluorocarbons (CFCs).<\/p>\n

Widely reported by scientific research as the most important man-made greenhouse gas, CO2 is estimated to exist in the atmosphere for more than 300 years, and thus accounts for the greatest portion of the warming of the Earth.<\/p>\n

2. Why do greenhouse gases cause global warming?<\/strong><\/h2>\n

Greenhouse gases stay in the atmosphere for hundreds of years. They act as a barrier, trapping the heat that radiates from the Earth\u2019s surface and prevent it from escaping into space. The heat kept under the atmosphere makes the Earth\u2019s temperature warmer.<\/p>\n

3. Global greenhouse gas emissions<\/strong><\/h2>\n

China, the US and India are the three largest greenhouse gas emitters in the world, according to the Rhodium Group’s report. Per capita emissions are calculated as the total emissions divided by population.<\/p>\n

According to the Australian Museum (2023), Australia, the US and Canada have the highest per capita emissions while in this figure, Vietnam lies at the world average (2.0 – 5.0 tons of CO2 per capita).<\/p>\n

4. Greenhouse gas emissions in Ho Chi Minh city<\/strong><\/h2>\n

Reports from Ho Chi Minh City Institute for Development Studies and Tuoi Tre newspaper (2023) showed that, Ho Chi Minh City generated 50 million tons of CO2, in which nearly one half (45%) came from the industrial production sector, and 30% from residential buildings. The proportion of electric vehicles accounts for only 0.16% of the total number of gasolien\/diesel two-wheeled vehicles\/motorcycles.<\/p>\n

5. Which businesses need to prepare a greenhouse gas inventory report?<\/strong><\/h2>\n

\u00a0<\/strong>Vietnam’s Ministry of Natural Resources and Environment drafts an updated list of establishments that are required to carry out greenhouse gas inventories<\/p>\n

This draft list includes 2,893 establishments, an increase of 981 establishments compared to the current list. Of these, the industry and trade sector accounts for the largest proportion with 2,261 establishments, followed by the transportation sector (81 establishments), construction (140 establishments), natural resources and environment (70 establishments), and agriculture and rural development (341 establishments).<\/p>\n
