CAQM submits report to Supreme Court: Vehicles contribute 19 to 24% to pollution in Delhi-NCR

The Commission for Air Quality Management (CAQM) has submitted a report before the Supreme Court, analyzing various sources of air pollution in Delhi-NCR. According to this report, the transport sector contributes 19 to 24 percent to polluting the air in Delhi, while biomass burning causes 17 to 23 percent of the pollution.

CAQM prepared this report by compiling data from several studies conducted between 2015 and 2025, meaning it is not based on a single study. The report states that the air in Delhi and NCR is affected by both local pollution and pollution coming from surrounding areas. Additionally, PM2.5 is identified as the main pollutant affecting Delhi's AQI.

The major sources of pollution during the winter season include: transport (vehicle emissions, accounting for 19 to 24%), biomass burning (pollution from burning garbage, wood, and crop residue, accounting for 17 to 23%), industry (emissions from factories and thermal power plants), dust (dust rising from roads, soil, and construction activities), and secondary particulate matter (fine particles formed by the interaction of gases from various sources).

The report also includes data on stubble burning incidents. According to it, there has been a 91.9% reduction in stubble burning incidents in Punjab between September 15 and November 4 compared to the year 2021, while the reduction in Haryana during the same period was 98.4%.

CAQM emphasized that Delhi's air quality is not only influenced by local pollution but also by pollution carried through the air from neighboring regions. This is why the results of various studies conducted between 2015 and 2025 were included while preparing the report to accurately assess the sources of pollution.

Study shows that a decline in rare mammal and bird species below 50 individuals does not lead to extinction

Zoologists concluded that rare mammal and bird species whose populations have decreased to below 50 individuals due to human activity are not doomed to inevitable extinction.

This conclusion is based on the study of the fate of 141 such species. It was noted that direct conservation measures were implemented for 51 of these species. These measures include captive breeding of animals, as well as combating invasive predators and competitors.

Thanks to these efforts, the population of 31 species, which accounts for 61 percent of the total number, was able to recover to a level of 100 individuals or more.

In contrast, among the 90 species for which no protective measures were applied, only two species managed to restore their population to 100 or more individuals. Furthermore, 33 species became completely extinct.

The results of this scientific study were officially published in the journal Proceedings of the Royal Society B: Biological Sciences.

Drone detected illegal sand mining in Bukhara region; materials handed over to prosecutor's office

Illegal extraction of sand and gravel mixture was discovered in the Bukhara region, causing environmental damage amounting to nearly 9 billion soms. This violation was found during a raid operation utilizing an unmanned aerial vehicle in the Gizhduvan district.

Environmental police officers found out that a local resident was extracting sand and gravel on the territory of the 'Kukcha' mahalla without obtaining the necessary permits, and the plot did not belong to him.

After calculations, specialists determined that the total damage inflicted on the environment amounted to 8.9 billion soms. The collected materials were sent to the prosecutor's office of the Bukhara region for further review.

The relevant authorities now face the task of conducting a legal assessment of the violator's actions, determining measures for holding them accountable, and ensuring compensation for the damage caused to nature.

The regional environmental department noted that the use of natural resources and illegal mining of minerals entails legal responsibility. The department emphasized that natural resources cannot be considered private property.

Tehran and Yerevan agree on joint efforts to combat pollution of the Aras River

Officials from Iran and Armenia have reached an agreement to strengthen joint measures to address the pollution problem of the Aras River, which serves as the common border between the two states and faces environmental damage.

The meeting took place during the 17th Conference of the Parties (COP17), held in Armenia from October 19 to 30. It was emphasized that relevant bodies and authorities will continue to resolve the river's environmental issues through coordinated national efforts, according to IRNA.

Ahmad Reza Lahidjandzadeh, Deputy Head of the Department of Environment (DOE), highlighted the strategic importance of the Aras River from economic, social, and cultural perspectives. He stated that preserving the river's ecology and improving water quality are necessary conditions for the region's sustainable development, as well as for protecting the health of residents along its banks.

This official also called for strengthening bilateral ties to prevent pollutants from entering the rivers and to improve the river's environmental management.

The Iranian delegation presented a report on the measures and actions taken by the country to limit the discharge of pollutants into the Aras River.

Furthermore, Hamid Zohrabee, Deputy Head of the Iranian Department of Environment (DOE), met with his Armenian counterpart Aram Meymaryan during COP17. Zohrabee proposed establishing a joint park of peace and friendship with Armenia to strengthen cross-border cooperation in biodiversity conservation and wildlife protection in the Caucasus region.

The proposed cross-border park would facilitate joint efforts to conserve biodiversity in northwestern Iran and the Caucasus region while simultaneously protecting critical wildlife habitats, including those used by the Persian leopard.

Both officials also discussed ways to expand environmental cooperation and address common issues, including the protection of the Aras River. Meymaryan welcomed this proposal and highly praised the active participation of the Iranian delegation at COP17.

It was decided to establish a working group to monitor the agreements reached after the summit.

COP17 was conducted in two stages: first technical discussions, followed by the ministerial segment. The leaders' summit took place on October 16, during which President Masoud Pezeshkian addressed the conference. This marked the first time the President of the Islamic Republic of Iran attended the Convention on Biological Diversity Conference of the Parties.

Speaking at the summit, Pezeshkian called for 'peace diplomacy' to protect biodiversity, condemning the destructive impact of aggressive wars as ecocide, and strongly urged the international community to create effective, transparent, and enforceable mechanisms for protecting natural heritage during military operations.

Shina Ansari, Head of the Department of Environment, also spoke at the meeting, stating that environmental diplomacy can be a tool of peace diplomacy, and that the link between biodiversity, peace, and security must be viewed as a bilateral process.

Ansari added that the connection between biodiversity and peace is not merely an ethical or political issue, but a fundamental problem in the field of environmental management, international law, and human security.

According to the Convention on Biological Diversity, the main causes of biodiversity loss, as is generally accepted, include land-use change, habitat destruction, pollution, unsustainable exploitation of natural resources, and climate change.

The Iranian delegation also met with Vivek Menon, Chairman of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN). They discussed ways to strengthen cooperation in developing programs for the management and conservation of endangered species. Special attention was paid to conservation and restoration programs for the Asiatic cheetah, great bustard, and Persian onager in their natural habitats, as well as the reintroduction of the Persian red deer into its natural ranges.

The parties also discussed increasing technical and scientific cooperation and providing funding under sanctions. Menon expressed hope that the current interaction between IUCN staff and Iranian experts would ensure the survival of endangered species such as the Asiatic cheetah in Iran.

During this summit, Iran officially joined the Coalition Actions for Endangered Species Recovery (CARES), whose goal is to strengthen international cooperation for the conservation and recovery of the country's wildlife. CARES was introduced at COP17 in Yerevan on October 16. Colombia and Armenia launched this initiative with the participation of 17 founding countries: Armenia, Belize, Brazil, Canada, China, Colombia, Costa Rica, Ecuador, Fiji, Indonesia, Madagascar, Mexico, Panama, Papua New Guinea, Peru, the United Kingdom, and Vanuatu. Iran became a member of the coalition as the 18th country.

The coalition is supported by the Reverse the Red Action partnership as its secretariat. The membership document was signed by Zohrabee on October 26. Speaking at the event, Zohrabee emphasized the need for fair distribution of resources and technologies to save endangered species. Iran's name will be listed on the coalition's website as a country that has developed action plans to conserve 40 species of wildlife to receive technical, scientific, and financial support from CARES.
