India at Epicentre as Air Pollution Becomes World’s 2nd Biggest Killer

India at Epicentre as Air Pollution Becomes World’s 2^nd Biggest Killer – Global Air Report 2025

KAKALI DAS

The recent State of Global Air Report 2025 has sounded a global alarm that should have received prime attention from policymakers, media, and the public alike. It reveals a truth both shocking and tragic: air pollution has become the second biggest cause of premature deaths across the world, right after hypertension.

What was once considered an environmental concern has now emerged as a public health emergency that threatens the very process of life , breathing itself. The report’s findings show that India has unfortunately become the epicentre of this crisis, where the act of inhaling air, essential for survival, has turned into one of the deadliest risks for millions.

According to the report, around 8 million people die prematurely every year because of air pollution. This figure alone should be enough to shake global conscience, but what makes it even more alarming is that India and China together account for 54 percent of these deaths. The numbers are grim, but the situation in India is particularly painful. Among children under the age of five, India leads with over 169,000 premature deaths annually due to air pollution. These are not just statistics; they represent countless families losing loved ones, often without realising that the invisible air they breathe is silently claiming lives every single day.

The report identifies two main culprits behind this deadly crisis – household air pollution and vehicular emissions. Both are directly linked to human activity, meaning this disaster is of our own making. Air pollution has now grown beyond an environmental issue; it has become a health, social, and economic problem affecting every aspect of life.

The report also draws attention to the inequality embedded in this global crisis. Air pollution is particularly concentrated in low and middle-income countries, where rapid industrialisation and urbanisation are taking place without adequate environmental safeguards. South Asia, especially India, is at the heart of this problem. The levels of fine particulate matter, known as PM2.5, in South Asia are more than double the global average and have remained consistently high for years. Even ozone exposure, another key pollutant responsible for respiratory illnesses, is much higher in South Asia than in most other regions.

India’s position in this grim ranking is deeply concerning. The country records the highest number of premature deaths caused by pollution globally, and it also tops the list for child deaths due to polluted air. Around 2.1 million premature deaths occur in India each year because of a combination of outdoor and household air pollution. What makes this even more distressing is that people are not only exposed to polluted air outside, on roads or in cities, but also within their homes, the very place that should provide safety and comfort.

In the national capital, Delhi, the situation has reached a critical level. The particulate matter concentration in Delhi NCR is 8 to 10 times higher than the safe limits prescribed by the World Health Organization. This is not a seasonal phenomenon; it has become a persistent reality, particularly worsening during the winter months when stubble burning, industrial emissions, and stagnant air combine to create a toxic blanket over the city. One in every five deaths in India, according to the report, is linked to air pollution.

India faces a dual burden– both outdoor and indoor air pollution are taking a severe toll. The government has introduced various schemes, such as the UjjwalaYojana, which promotes LPG use instead of firewood or coal for cooking, and the FAME scheme, which supports the electrification of public transport. However, while policies exist on paper, implementation remains far from satisfactory. The gap between policy formation and execution continues to widen, leaving millions of citizens exposed to deadly air every day.

Globally, there is also a clear divide in how different regions are affected. Europe and North America, for instance, have managed to reduce pollution-related mortality through stricter environmental standards and clean energy transitions. In contrast, regions like Asia and Africa continue to suffer the highest mortality burdens, while also struggling with economic pressures to industrialise and urbanise. This exposes the global inequality in environmental health, where developing nations are paying the price for both their own growth and the unchecked consumption patterns of the developed world.

Air pollution does not act alone. It is a catalyst for other life-threatening diseases, including heart attacks, strokes, diabetes, lung cancer, and chronic respiratory conditions. The damage it causes is both direct and indirect, eating away at the health and productivity of societies over time.

When we examine the economic cost of this crisis, the picture becomes even darker. The report highlights that India loses around 1.5 percent of its GDP due to air pollution-related health problems and productivity losses. The country’s economy is bleeding silently as its people fall sick more often, die earlier, and contribute less to national growth. The healthcare burden is rising sharply because air pollution leads to chronic illnesses that require long-term treatment.

The poor, who already struggle for basic needs, are hit the hardest.They have fewer healthcare options, live in areas with worse air quality, and cannot afford to protect themselves. Thus, air pollution not only destroys health but also deepens social inequality, trapping vulnerable groups in a cycle of poverty and illness.

Air pollution also damages education and the development of human capital. Children growing up in polluted environments suffer from reduced lung capacity, cognitive decline, and poor academic performance. This affects the future workforce of the nation, meaning air pollution is not just killing people today, it is stealing the potential of future generations.

The causes of this pollution are multiple. Outdoor sources include vehicular emissions from diesel and petrol, industrial discharges, construction dust, and agricultural stubble burning. These are aggravated by weak enforcement of environmental laws and poor waste management. Indoor sources are equally deadly. Millions of households still rely on biomass, coal, and wood for cooking, especially in rural and low-income areas. Poor ventilation, burning of incense, and even mosquito coils and sprays contribute to toxic indoor air. Together, these outdoor and indoor sources create a deadly cocktail that the population breathes daily, often unknowingly.

Addressing air pollution requires understanding that it is not merely an environmental or technical issue. It is a scientific, social, and moral challenge. The solution must involve awareness, behavioural change, technological innovation, and above all, strong political will. Every citizen has a role to play, from reducing personal emissions to demanding accountability from industries and governments.

The crisis must also be understood in economic and geopolitical terms. Countries like India and China are industrialising at a rapid pace, and this growth is heavily dependent on fossil fuels. Yet, the developed nations, which have already benefited from centuries of industrialisation, are now pushing for global climate commitments. There must be technology sharing and fair financial support from the global north to help developing nations transition towards cleaner energy without sacrificing their growth. This is not just an environmental necessity but a matter of justice.

Clean air should not be seen as a luxury or privilege. It is a basic human right, as fundamental as food, water, and shelter. Denying people clean air is equivalent to denying them the right to live with dignity. The government must recognise this and treat the issue with the urgency it deserves.

There is still hope if immediate and coordinated action is taken. India has pledged to achieve net zero carbon emissions by 2070, but this target can only be met with sustained commitment, technological investment, and community participation. Real-time monitoring of air quality, stricter emission controls, incentives for green energy, and awareness campaigns are essential steps forward.

Global cooperation is equally crucial. Air pollution knows no borders, what happens in one region affects the entire planet. Therefore, the world must come together not just in conferences and declarations but through real action and shared innovation. Richer nations must assist poorer ones in adopting clean technologies, just as all must hold each other accountable for meeting environmental goals.

The State of Global Air Report 2025 is not just a study; it is a warning and a mirror. It shows how humanity’s progress, greed, and negligence have turned air, the very essence of life into a, weapon of slow destruction. Yet it also reminds us that this crisis is reversible. The same human will that created this problem can also solve it, if guided by compassion, science, and determination.

Air pollution is not someone else’s problem; it is everyone’s crisis. Every breath we take connects us to this planet, and every polluted breath shortens not just an individual’s life but the collective future of humankind. It is time to recognise that the fight for clean air is not separate from the fight for health, equality, and survival. The world cannot afford to treat it as a side issue any longer. The call is clear – clean air is not optional, it is essential, and the time to act is now.
