Patna, Feb 4 (PTI): The increasing concentration of carbon dioxide (CO2) at various locations in Patna has raised concerns among environmental experts, prompting calls for continuous monitoring and mitigation strategies, according to Bihar State Pollution Control Board (BSPCB) officials.
A recent survey conducted by the United Nations Development Programme (UNDP) titled Hyperlocal Mapping of Air Pollution and Greenhouse Gas Emission revealed that CO2 levels in certain areas of the city have significantly exceeded the global average. The study, conducted from June 7, 2024, to January 29, 2025, indicates a sharp rise in CO2 emissions across different parts of the state capital.
CO2 Levels Surging Above Global Average
According to the survey report accessed by PTI, Patna’s Samanpura locality recorded a staggering rise in CO2 levels, climbing from 440.9 parts per million (ppm) in June 2024 to 940.8 ppm in January 2025. The highest concentration was noted in December 2024 at 959.1 ppm, while November recorded 912.2 ppm.Other locations also reported elevated CO2 levels in January 2025:
- Shri Krishna Memorial – 515.4 ppm
- Shimli Nabab Ganj – 513.6 ppm
- Mainpura (Danapur Road) – 493.7 ppm
- Kidwaipuri – 490.6 ppm
- Taramandal – 480.7 ppm
- Ashok Netaji Path-Balapur – 446.4 ppm
- Rukanpura – 445.3 ppm
- Shri Krishnapuram-Danapur – 437.2 ppm
Concerns Over Rising CO2 and Its Impact
Although CO2 is not classified as an air pollutant, its high concentration contributes to global warming, which could lead to an increase in local temperatures during peak summer, experts warn.BSPCB Chairman D.K. Shukla emphasized the need for urgent action. "This is the first time BSPCB, in collaboration with UNDP, has conducted such a survey in Patna. The findings indicate an alarming rise in CO2 levels, which are much above the global average. While CO2 is not an air pollutant, its increasing concentration contributes to global warming and requires mitigation efforts," he stated.
Shukla attributed the rise in CO2 to high fossil fuel emissions and a reduction in natural carbon sinks such as wetlands. "The declining number of wetlands, which play a crucial role in absorbing CO2, is a major factor in Patna’s rising emissions," he added.
Experts Call for Immediate Mitigation Measures
To tackle the growing CO2 levels, Shukla proposed massive afforestation efforts in strategic locations. "Planting trees in the right places can significantly reduce CO2 levels. People should also consider indoor plants that help in lowering CO2 and improving air quality. Additionally, reducing the use of fossil fuels is crucial," he said.Environmental experts echoed similar concerns, stressing the need for policy interventions and stringent implementation of climate action plans.
Anumita Roychowdhury, Executive Director of the Centre for Science and Environment (CSE), emphasized the need for a multi-pronged approach to tackle CO2 emissions. "Authorities must intensify efforts to curb emissions from key sources such as industry, vehicles, waste and biomass burning, and solid fuel usage in households. Adopting environment-friendly cooking methods and promoting clean energy solutions will be vital in lowering emissions," she said.
However, Chandra Bhushan, CEO of the International Forum for Environment, Sustainability & Technology (iFOREST), pointed out that high local CO2 concentrations do not necessarily correlate with temperature rise in Patna. "The greenhouse effect is a global phenomenon, not a local one. The reasons behind the high CO2 levels in Samanpura need thorough investigation, especially considering its proximity to the airport," he noted.
Call for Action
Experts agree that while Patna’s rising CO2 levels demand urgent attention, addressing the issue requires sustained monitoring, policy interventions, and public awareness initiatives. Promoting renewable energy, improving urban greenery, and reducing fossil fuel dependency are critical steps toward mitigating the impact of increasing CO2 levels in the city.
