Satellite images provide clear picture of greenhouse gas emissions
A research project by the Department of National Remote Sensing under the Ministry of Natural Resources and Environment (MoNRE) has for the first time used images provided by VNREDSat-1, Vietnam’s very first remote sensing satellite, in calculating carbon dioxide emissions.

Hanoi (VNA) – A research project by the Department of National RemoteSensing under the Ministry of Natural Resources and Environment (MoNRE) has forthe first time used images provided by VNREDSat-1, Vietnam’s very first remotesensing satellite, in calculating carbon dioxide emissions.
Using the VNREDSat-1 imagery and geographic information system (GIS)application, the project completed digital databases on the ecological, soiland climate conditions of the country and the Tay Nguyen Central Highlands, aswell as a database to calculate greenhouse gas emissions, while setting up mapsfor land cover in Tay Nguyen localities and its changes.
High-resolution images provided by VNDREDSat-1 help improve the accuracy ofland-cover mapping, thus improving the reliability of calculation of thegreenhouse gas emissions in different areas.

Director of the Ozone Layer Protection and Low Carbon Economy DevelopmentCentre under the MoNRE’s Climate Change Department Ha Quang Anh said that alongwith creating a giant stride in technology in Vietnam, the project helpspolicy-makers outline effective measures to mitigate indiscriminate miningexploration, and promote environmental protection.
The project showed that changes in forest reserves, biomass, and land uses havegreat impacts on greenhouse gas emissions in energy and agriculture, 20 percentof which is contributed by deforestation and changes in land use.
The Central Highlands, which accounts for 35.7 percent of the country’s forestareas, absorbs 50 percent of the nation’s total carbon dioxide emissions, theproject reveals./.
Measures to reduce greenhouse gas emissions were discussed at a conference organised by the Ho Chi Minh City Department of Natural Resources and Environment this week.
The Ministry of Agriculture and Rural Development (MARD) and the World Bank (WB) - the trustee agency of the Forest Carbon Partnership Facility (FCPF) - signed an Emissions Reduction Purchase Agreement (ERPA) at a ceremony on October 22.
After basically containing the spread of COVID-19, Vietnam is becoming the first developing country to adopt carbon pricing in the post-pandemic period to help guide a cleaner recovery, the site eastasiaforum.org reported in an article on November 19.
Under the directive, the PM instructed relevant agencies to regularly inspect, supervise and proactively implement disaster prevention, response and rescue measures in line with their assigned roles and mandates, ensuring readiness, avoiding passivity or delays, and maintaining operational continuity amid ongoing political and administrative restructuring at levels.
According to Dr. Vu Anh Tuan, Deputy Director General of the Vietnam Space Centre and head of the project, this is the first study in Vietnam to simultaneously employ Sentinel-2 satellite data, advanced machine learning algorithms, and the Google Earth Engine (GEE) cloud computing platform to model and monitor key seawater quality parameters.
The Deposit Return System is seen as a potential instrument for effectively advancing Vietnam’s vision of a circular economy, as outlined in Article 142 of the 2020 Law on Environmental Protection.
The figures were highlighted in a Pre-Feasibility Study on a DRS tailored for single-use beverage packaging in Vietnam, conducted by Eunomia Research & Consulting.
Young people should not view AI as salvation but rather as a tool under human control. Young creators should focus on learning and accumulating practical knowledge, using AI as a tool to carry out artistic projects in the most effective and cost-efficient manner.
Saigon Hi-Tech Park’s ambitious 50% renewable energy goal far exceeds the city’s 15% target, positioning the park as a trailblazing “living lab” for sustainable energy solutions.
Vietnam's economic losses from natural disasters are estimated to account for 1 to 1.5% of GDP annually - a steep price that will continue to rise unless the country takes strong action.
Wutip, the first storm in the East Sea so far this year, has wreaked havoc across central Vietnam, claiming lives, displacing residents, and causing widespread damage to houses, crops, and infrastructure, the Department of Dyke Management and Disaster Prevention and Control reported as of 6:30 pm on June 13.
The tremor occurred at 7:39:46 am (Hanoi time), with the epicentre located at latitude 14.924°N and longitude 108.236°E, at a depth of approximately 8.1 kilometres. The natural disaster risk level was classified as 0 – the lowest on the scale.
Addressing a session on “Accelerating Financing for Resilience: Tailored Solutions for Disaster Risk Reduction,” Deputy Minister Hiep emphasised Vietnam's proposal in building sustainable financing in response to natural disasters, which aligns with the Sendai Framework for Disaster Risk Reduction's goals.
Vietnam has demonstrated its strong commitments by participating in global sustainable development forums, signing multiple free trade agreements, and attracting support from international partners for the implementation of the SDGs.
The fight against plastic pollution could not succeed through isolated efforts, but it must be a collective endeavour involving the entire political system, businesses, citizens, and the international community, said Minister of Agriculture and Environment Do Duc Duy.
Lang Son Global Geopark, with its outstanding geological values, cultural heritage, and unique natural landscapes, represents a valuable addition to UNESCO’s global geoparks system.
In 2019, Quang Ninh became one of the first localities in Vietnam to launch a province-wide campaign against plastic waste, mobilising the participation of the political system, the business sector, and the general public. Other localities—such as Hai Phong, Da Nang, Binh Duong, and Ho Chi Minh City—have also effectively implemented waste-sorting initiatives at source, along with models for plastic-free markets and urban areas.
This year’s World Oceans Day on June 8 is themed 'Wonderful Oceans: Sustaining What Sustains Us', while World Environment Day is on June 5 with the theme: 'Beat Plastic Pollution'.
According to Director of the provincial Department of Agriculture and Environment Le Huu Toan, a fire prevention and control plan has been in place since the dry season began, including round-the-clock patrols and rapid-response teams to snuff out fires before they could spread.
Renowned artists including Ha Anh Tuan, Den Vau, and Phan Manh Quynh, along with many directors and attendees, took part in planting hundreds of rare tree species such as mun (Diospyros mun) and cho chi (Parashorea chinensis) in the Thung Bong area of the Cuc Phuong National Park, contributing to forest ecosystem restoration.
The dispatch noted that since the beginning of 2025, natural disasters have claimed 29 lives and left several others missing. A total of 67 houses have collapsed, and 2,342 homes have been unroofed or damaged.
