The state of the atmosphere in our country has taken a worrying turn recently, reversing the improving trend observed after the health crisis. Although the skies may appear clear to the naked eye, the data collected indicate that the quality of the air we breathe has suffered. a clear setbackDriven primarily by weather factors and a strong return to traditional mobility habits. Well, the situation has become complicated just when we thought we were on the right track.
The most recent reports, which analyze the situation throughout the entire country, reveal an uncomfortable reality: if we apply the criteria that Europe will demand very soon, it turns out that 32,6 million people In Spain, people have been exposed to unhealthy levels of pollution. This means that two out of every three citizens have lived with an atmosphere laden with harmful substances, highlighting the urgent need to take seriously the transition to more livable cities that are less dependent on cars.
Ozone and heat: a dangerous mix

One of the major negative contributors has been tropospheric ozone, a gas that doesn't come directly from exhaust pipes, but rather forms in the air when other pollutants react under intense solar radiation. During the summer months, the intense heat waves have caused this pollutant to reach levels of... worst records since 2015This far exceeds the thresholds for providing information to the population in numerous autonomous communities. It's a serious problem, as it affects both large cities and the most remote rural areas.
Rising temperatures are not the only culprit, as the burning of fossil fuels has increased significantly. Oil consumption, especially linked to the aviation fuels And road transport has returned to levels not seen for over a decade. This dependence on crude oil fuels a vicious cycle: more emissions generate more warming, and the heat triggers the formation of toxic gases in our streets, complicating the health of those with respiratory conditions.
As if that weren't enough, nature has also contributed to this bleak scenario. The intense wave of forest fires The dust storm experienced during August injected a huge amount of fine particles into the atmosphere, worsening the situation in regions that usually enjoy cleaner air. Although winter rains helped to clear the air somewhat and prevented prolonged episodes of haze, they were not enough to offset the impact of an extremely hot and dry summer.
In specific areas like the Community of Madrid, ozone levels have shattered historical records. Authorities have had to repeatedly activate information protocols as these levels have been exceeded. 180 micrograms per cubic meterThis is a limit that should put us all on alert. In Extremadura, the situation hasn't been much better, with a vast area of ​​forest and farmland affected by this gas, which, in addition to harming us, seriously damages the health of the forests and crops.
The gap between health and current regulations

There is a striking disconnect between what current law says and what medical experts recommend. While Spanish legislation still permits certain levels of pollution, the World Health Organization He warns that these limits are far too lenient. If we strictly followed the WHO's recommendations to protect our health, virtually the entire Spanish population would be breathing air that doesn't meet minimum safety standards. This is no laughing matter, as lungs don't adhere to legal deadlines.
Nitrogen dioxide, that gas we readily associate with diesel engines, remains king of cities. Although there has been a slight overall improvement, large metropolitan areas Madrid and Barcelona continue to suffer from concentrations that exceed what will be legal from 2030 onwards. This indicates that current measures are clearly insufficient to achieve the sustainability goals we have set for ourselves as a society within the European framework.
One statistic that is truly chilling concerns the youngest children. Measurements taken in school environments Studies from various cities have shown that children breathe air that is much dirtier than official monitoring stations indicate. This is because pollution is concentrated at ground level and at school entrances, where traffic entering and leaving generates pollution spikes that often go undetected by institutional measurement systems.
All this polluted air has a cost that goes beyond health. It is estimated that poor air quality contributes to... impact on the economy This is equivalent to 2,4% of Spain's Gross Domestic Product. Between medical expenses for the more than 60.000 annual hospital admissions and lost productivity, the bill amounts to approximately 32.000 billion euros. Breathing difficulties not only shorten our lives, but also cost us dearly as a country.
Political inaction and lack of transparency

One of the points most criticized by environmental organizations is the slowness of the authorities. Despite having European funds To transform mobility, half of the cities with more than 50.000 inhabitants have still not implemented their Low Emission Zones. This legal delay leaves citizens unprotected against pollution spikes, while the deadlines for complying with European Union regulations continue unabated.
To make matters worse, access to public information has suffered a major setback. The national air quality monitor, the tool where any citizen can check what they are breathing in real time, became inoperative after a cyberattack on the server from the relevant ministry. Months after the incident, the website still isn't working properly, creating an information gap that prevents vulnerable people from taking basic precautions before going out.
Ozone management is also under intense scrutiny. Eight autonomous communities have still not approved specific plans to combat this pollutant, despite repeated requests. court judgments which forces them to do so. The absence of a coordinated National Ozone Plan means that the measures are isolated patches rather than a solid strategy to protect the atmosphere in the long term. It's like trying to put out a fire with a glass of water.
To reverse this situation, experts agree that there is no alternative but to drastically reduce motorized traffic. Promoting active mobility and public transport Electric vehicles are non-negotiable steps, as is limiting short-haul flights and committing to real energy savings. It's not just about swapping a combustion engine car for an electric one, but about rethinking how we get around and how we consume energy in our daily lives.

To try to mitigate these effects, a series of urgent actions are proposed:
- Real decrease in private vehicle traffic in urban centers.
- Promoting travel by foot, bicycle and electric buses.
- Establishing stricter limits on emissions from shipping and aviation.
- Acceleration of stalled regional air quality improvement plans.
At the end of the day, what the 2025 data is telling us is that we cannot let our guard down. The combination of increasingly extreme weather and oil-based mobility is taking its toll on our health and the natural environment. Improving the real air quality In Spain, it requires political courage to enforce existing laws and complete transparency so that citizens are aware of the risks. Only with a profound transformation of our energy and transportation model will we ensure that breathing in our cities ceases to be a risky activity for thousands of people every year.
