The link between air pollution and public health is becoming increasingly clear, with growing evidence pointing to its significant contribution to cancer and other serious illnesses. A renewed focus on tackling air pollution is emerging, not as a standalone issue, but as intrinsically linked to our global energy systems. The European Code Against Cancer now explicitly recognizes this connection, advocating for a fundamental shift in how we produce and consume energy to safeguard public health.
While individual actions like using air filters and limiting wood burning can offer some localized relief, experts argue these are insufficient solutions. The core of the problem lies in the pollutants released by the burning of fossil fuels – a major driver of both climate change and respiratory illnesses. Addressing this requires a large-scale rethinking of energy infrastructure and a rapid transition to cleaner alternatives.
The Energy-Pollution Connection
Energy production accounts for over three-quarters of global greenhouse gas emissions and simultaneously releases harmful pollutants like fine particulate matter (PM2.5) and nitrogen oxides. These pollutants are directly linked to a range of health problems, including cancer, respiratory diseases, and cardiovascular issues. According to the European Code Against Cancer, in 2021, an estimated 23,000 cancer deaths in the European Union were attributable to ambient particulate matter.
The shift isn’t solely about adopting cleaner energy sources, but also about changing how energy is used. Technology already exists – including heat pumps and energy management solutions – to improve efficiency and reduce emissions. On a larger scale, electrifying energy-intensive sectors like industry, transport, and buildings offers significant potential for reducing reliance on fossil fuels and improving air quality.
Protecting Vulnerable Populations: A Focus on Schools
The impact of air pollution is particularly acute for vulnerable populations, and children are especially at risk. Recognizing this, the European Code Against Cancer specifically recommends that new schools should not be located near busy roads, and existing schools in high-traffic areas should be incentivized to use air filters. This recommendation is gaining traction, with advocates highlighting the potential benefits for student health and academic performance.
Installing air filters in schools is a cost-effective measure to remove harmful particulates and pathogens from the air. A study conducted in Milan demonstrated that implementing air filtration systems in schools led to a more than 10% decrease in student absenteeism. Research from the US, involving 100 schools, showed measurable improvements in maths and reading scores when indoor air quality was improved, findings corroborated by a cohort study of over 8,000 children in the UK.
Ruth Brooker of Clean Air for Kids emphasizes the affordability of this intervention, stating that providing clean air in schools could cost less than £10 (approximately $12.75 USD as of March 13, 2026) per child per year, ensuring they have the same right to breathe clean air as they do to drink clean water.
Beyond Individual Action: Systemic Change is Key
While individual behavioral changes and localized solutions like air filters have a role to play, experts stress that a systemic overhaul of energy systems is essential. Frédéric Godemel of Schneider Electric argues that focusing solely on individual actions, such as limiting wood burning, doesn’t address the root cause of the problem. A fundamental shift towards cleaner, more efficient energy systems is required to achieve lasting improvements in air quality and public health.
This transition involves not only investing in renewable energy sources but also accelerating the electrification of various sectors and improving energy efficiency across the board. The European Code Against Cancer’s emphasis on air pollution as a policy priority is a crucial step in driving this change, recognizing that a healthy environment is fundamental to a healthy population.
The conversation surrounding air pollution and health is evolving, with a growing understanding of the interconnectedness between energy systems, environmental quality, and public well-being. Continued research, policy changes, and technological innovation will be critical in shaping a future where clean air is a reality for all. What remains to be seen is the speed and scale at which governments and industries will embrace the necessary transformations to achieve this goal.
