Air pollution remains one of the world’s biggest public health threats, contributing to millions of premature deaths each year. Recognising the urgent need for action, more than 50 countries have committed to reducing the health impacts of air pollution by 50% by 2040 at a World Health Organization (WHO) conference. The pledge comes as air pollution-linked diseases, including lung ailments, heart conditions, and strokes, continue to burden healthcare systems globally. Experts stress that pollution-related deaths could keep rising without significant intervention, particularly in low- and middle-income nations where air quality regulations remain weak.
A Deadly Public Health Crisis
Air pollution is responsible for an estimated 7 million deaths annually, with toxic air contributing to respiratory and cardiovascular diseases. According to the WHO, 99% of the global population breathes air that exceeds safe pollution limits, exposing billions to harmful, delicate particulate matter (PM2.5), nitrogen dioxide (NO₂), and ground-level ozone.
The burden of pollution falls disproportionately on vulnerable populations. Children, pregnant women, and the elderly face heightened risks, with studies linking prolonged exposure to polluted air to reduced lung development in children and increased pregnancy complications. In heavily polluted regions, such as India’s National Capital Region and parts of China, chronic respiratory illnesses have surged, placing immense pressure on healthcare systems.
The 2040 Commitment: What It Means
At the WHO conference, participating nations agreed to develop and implement policies to halve pollution’s health impact by 2040. This includes stricter emissions controls, cleaner transportation policies, and investments in renewable energy. Many of these measures align with existing climate commitments, as cutting pollution often goes hand in hand with reducing carbon emissions.
Some countries have already introduced ambitious policies. The European Union has tightened air quality standards to bring pollution levels closer to WHO recommendations. Meanwhile, nations like Norway and Canada have committed to phasing out fossil fuel-powered vehicles in favor of electric alternatives. However, experts caution that more vigorous enforcement and accountability mechanisms will be needed for this global commitment to be successful.
Challenges in Implementation
While the pledge marks an important step, translating commitments into meaningful change will require overcoming significant challenges. Economic reliance on coal and fossil fuels complicates the transition to cleaner alternatives in rapidly industrialising nations. Many developing countries also lack the infrastructure to support widespread adoption of electric vehicles and renewable energy.
Moreover, air pollution is often a cross-border issue, meaning national efforts alone may not be enough. In South Asia, the burning of crop residues contributes significantly to air pollution, releasing:
- 70% of fine particulate matter (PM2.5) harms respiratory health. These microscopic particles worsen conditions like asthma and chronic obstructive pulmonary disease (COPD), increasing haze and reducing visibility.
- 40% black carbon (BC), a short-lived climate pollutant that accelerates ice and snow melt by darkening surfaces and lowering their ability to reflect sunlight.
Coordinated international efforts, such as technology-sharing agreements and stricter regional air quality regulations, will be crucial in tackling these transboundary pollution challenges.
A Race Against Time
With pollution-related deaths projected to rise, action over the next decade will determine whether this commitment translates into real health benefits. The WHO has urged governments to integrate air quality policies with broader health and climate goals, emphasising that reducing pollution saves lives, cuts healthcare costs, and improves economic productivity.
For millions living in cities choked by smog, the pledge offers hope. However, as history has shown, pledges alone are not enough—sustained political will and public pressure will be critical in ensuring that clean air becomes a reality rather than just an aspiration.
