Much before air pollution emerged as a critical health and environment issue in India, we developed state-of-the-art capacities for studying air quality. Our research focusses on a range of issues, including ambient air quality and apportionment of contributing sources , indoor air quality assessment for urban and rural households, regional scale assessment, impacts on health and agriculture, and capacity building of stakeholders for better management. Our research and analyses have been taken into account by policy makers for improvements in various standards and policies.

वायु प्रदूषण से बचने के विकल्पों को प्राथमिकता देने की सख्त ज़रूरत

Mr Ajay Shankar

पिछले महीने उत्तर भारत में वायु प्रदूषण असहनीय स्तर पर पहुंच गया था। ज़हरीली हवा को देखते हुए दिल्ली-एनसीआर में जन स्वास्थ्य आपातकाल की घोषणा कर दी गयी थी। निर्माण कार्यों और पूरी ठंड के दौरान पटाखे फोड़ने पर प्रतिबंध लगा दिया गया। पर वायु प्रदूषण की समस्या सिर्फ़ दिल्ली तक ही सीमित नहीं है। भारत के दूसरे शहर भी वायु प्रदूषण से हांफ रहे हैं। दिल्ली के पड़ोसी राज्य उत्तरप्रदेश के प्रयागराज (इलाहबाद), कानपुर, आगरा, और लखनऊ भी प्रदूषित शहरों की श्रेणी में आते हैं।

These suggestions are based on the collaborative research study by Indian and Finnish research institutes.


Hope on air quality: How air quality in north India can be transformed within 5 years

Air pollution in Delhi has been rightly described as a health emergency. In the Union budget, the finance minister enhanced the outlay for reducing air pollution to Rs 4,400 crore, almost a tenfold increase, and states should follow this lead. The National Clean Air Program, started over a year back, has the goal of improving air quality by 25-30%. Since the causes of, and mitigation measures for air pollution are better understood now, it is time to raise the nation’s ambition to getting fully clean air by 2025. Getting clean air needs smart interventions.

Poisoning air in the breath will be even more dangerous in 10 years, steps have to be taken together

Air pollution is a problem that has no immediate solution but will have to be constantly trying to reduce it. To deal with this, the government has also initiated several initiatives. For example, the Ujjwala scheme provides LPG fuel to the poor households who use solid biomass for cooking such as wood and cow dung. Pollution from the smoke emanating from it not only spreads but also has a bad effect on the health of women. Similarly, encouraging efforts are being made at various levels to promote low carbon technologies for power generation and transportation.

वायु प्रदूषण एक ऐसी समस्या है जिसका तत्काल कोई समाधान नहीं है लेकिन इसे कम करने के लिए लगातार प्रयास करते रहना होगा। इससे निपटने के लिए सरकार ने कई पहल भी शुरू की है उदाहरण के लिए, उज्ज्वला योजना उन गरीब घरों को एलपीजी ईंधन मुहैय्या करवाती है जो खाना पकाने के लिए ठोस बायोमास का इस्तेमाल करते हैं जैसे-लकड़ी और गोबर के उपले। इससे निकलने वाले धुएं से प्रदूषण तो फैलता ही है साथ ही यह महिलाओं के स्वास्थ्य पर ख़राब असर करता है। इसी प्रकार, बिजली उत्पादन और परिवहन के लिए कम कार्बन प्रौद्योगिकियों को बढ़ावा देने के लिए विभिन्न स्तरों पर उत्साहजनक प्रयास किए जा रहे हैं।

People walking the streets with N95 masks on, odd-even scheme coming into action for vehicles, schools shutting down to avoid further trouble... we're talking about that time of the year when air pollution becomes a major topic of discussion. The problem exists throughout the year and the reasons are plenty. All that is required is some administrative measures and small steps by individuals to curtail air pollution.

Air pollution kills more people than poor diet, smoking, lack of physical fitness and high blood pressure do, put together. It is an ongoing public health emergency in India, claiming one in every eight lives. Larger portions of India's economy are being lost to health issues, reduced agricultural yields and damage to biodiversity and ecosystems caused by air pollution.

Emissions control in thermal power stations: Issues, challenges, and the way forward

February 21, 2020

As per TERI's analysis, of the total environmental pollution in 2016, the power sector reportedly accounted for 51% of sulphur dioxide (SO2), 43% of carbon dioxide (CO2), 20% of oxides of nitrogen (NOx), and 7% of PM2.5 emissions.

Crop residue management: Solution to achieve better air quality

January 30, 2020

Residents of different cities (probably villages too) of India breathe some of the least healthy air of the globe. During 2017, about 76.8% of the population of India were exposed to annual population-weighted mean PM2·5 greater than the limit recommended by the National Ambient Air Quality Standards (NAAQ: 40 mg/m3) (Balakrishnan, Dey, Gupta, et al. 2019). Over last five years, the annual population-weighted mean ambient PM2·5 concentrations were significantly higher over the Indo- Gangetic Plain (IGP) region in comparison to other parts of the country.

Fleet Modernization: A solution to achieve better air quality

December 10, 2019

India's transport demand has grown from a total of 5.3 million in 1981 to 230 million in 2016, with two-wheelers and cars having 73% and 14% share, respectively. Commercial vehicles though constitute only about 5% of the total fleet, contribute to nearly 80% of total PM emissions.

Phase-wise implementation of fleet modernization (transforming pre BS-IV commercial vehicles to BS-VI) would lead to a 40-80% reduction in PM and NOx emissions from the sector by 2025.

Opportunities with Biofuel: Co-benefit of Air Quality Improvement

December 5, 2019

While biofuels have been discussed as one of the ways to reduce air pollution, changing the process of bio-diesel production is needed to reduce tailpipe emissions of nanoparticles. These are lesser known pollutants even more harmful than PM2.5 and PM10.

The transport sector is an important contributor to pollution in cities. The sector accounts for a significant contribution in PM2.5 concentrations in most Indian cities. In Bengaluru, the sector accounts for almost 50% of PM2.5 concentrations.

Advancement of Fuel Quality and Vehicle Emissions Norms to Improve Urban Air Quality in India

September 14, 2014

The health impacts of the deteriorating ambient air quality in urban cities worldwide are of serious concern. According to the World Health Organisation (WHO), one of the top ten causes of death is attributed to air pollution (WHO, 2010); diesel engine exhaust, for instance has been linked with increased lung cancer risk (WHO, 2012). Motor vehicles are one of the major sources contributing to air pollution at local, regional and global scale. India, which has the largest number of megacities in the world, is facing serious air quality problems in its urban areas.
