Two Million Child Asthma Cases Are Linked to Vehicle Emissions Every Year

In the mosaic of human health challenges, childhood asthma emerges as a consistent and pervasive threat, with one surprising culprit behind this chronic respiratory condition: the vehicles that have become a fixture of modern life. According to a report published in the esteemed journal Lancet, a staggering two million childhood asthma cases globally are tied to vehicular emissions annually. This revelation isn’t just alarming; it’s a call to immediate, pointed action that intersects public health and policy in crucial ways.

A Toxic Legacy of Traffic

Dieselgate, a term coined to describe the scandal that rocked the automobile industry in 2015, revealed that many leading car manufacturers had been rigging their vehicles to cheat emissions tests. Fuelled by the urgent need to reduce carbon emissions, diesel vehicles rose to prominence due to their better fuel efficiency. However, the ‘clean diesel’ claim, which promised reduced emissions, was found to be a farce. The cover-up involved software in diesel cars that could detect when they were being tested, changing the performance accordingly to improve results. But on the roads, these vehicles produced nitrogen oxides, a group of toxic pollutants that cause respiratory diseases, including asthma in children, in unprecedented amounts.

Peugeot’s involvement in the diesel emissions scandal in France illustrates the complexities of this issue, hinting at a broader problem within the automotive industry, where the pursuit of profit occasionally overshadows environmental and health considerations. The repercussions ripple outward, implicating an intricate web of stakeholders ranging from consumers who bought affected vehicles to the global community facing the health impacts of such widespread air pollution.

Breaking Down the Data

Researchers at George Washington University studied the impact of nitrogen dioxide (NO2) from traffic on children’s asthma cases from 2000 to 2019. They discovered that out of 1.85 million new asthma cases linked to NO2, two-thirds occurred in urban areas. Intriguingly, asthma cases in urban regions decreased from 20% in 2000 to 16% in 2019, likely due to stricter clean air regulations in wealthier countries like the U.S. 

Unsurprisingly, this correlation between asthma and vehicular emissions bears significant geographic disparities. The burden is not evenly distributed, with regions like South Asia, the Middle East, and Sub-Saharan Africa, where robust clean-air regulations are the exception rather than the norm, shouldering the highest share of childhood asthma cases attributed to traffic pollution.

This lopsided toll is both an indictment and a challenge to the global community. It underscores the need for international cooperation, funding mechanisms, and knowledge sharing that can ensure that the right to clean air is not a privilege but a universal entitlement, particularly for those with the highest stake in our collective future – our children.

Susan Anenberg, a co-lead author of the study, emphasised the risks NO2 poses for children developing asthma, especially in urban locales. She stressed that prioritising clean air is vital for child health. By reducing fossil fuel transportation, we can improve respiratory health and potentially lower paediatric asthma cases and deaths while also mitigating greenhouse gas emissions for a healthier climate.

Policy and Personal Responsibility

For any meaningful change to occur, the findings of this study must catalyst swift action on multiple fronts. Policymakers stand at the forefront, armed with the ability to enact and enforce the regulations that can steer our trajectory away from this public health crisis.

However, the onus is not solely on governments and authorities. There is an individual responsibility to be shouldered as well, evident in the choices we make as consumers and the pressure we exert through collective advocacy. The conscious decision to hold manufacturers accountable for diesel claims, prioritise sustainable modes of transport, demand cleaner fuels, and support policies that reduce vehicular emissions are all steps within our power to mitigate the risk for the coming generations.

What Lies Ahead

Climate change and air pollution are no longer abstract future scenarios or isolated ecological problems. They are active influencers of public health, with tangible impacts that are quantifiable and, more distressingly, preventable.

In the case of childhood asthma linked to vehicle emissions, the prognosis isn’t set in stone. It remains within our grasp to change the trajectory, reduce the toll, and offer a better future to the children who are its victims. The question that remains is whether we’ll have the fortitude to confront this systemic issue with the urgency it demands.

The study gives voice to the harrowing impact of vehicular emissions, delivering a potent and inescapable message about the nexus of our transportation choices and the health of our children. It serves as a rallying cry for a concerted, multisectoral response that values the sanctity of the air our children breathe.

The time to act is now. Our cities, our communities, and our children can’t afford to wait. Visit to learn how you can make a difference.
