Every January 28 , the World Day for the Reduction of CO2 Emissions is celebrated, a date marked by the United Nations to reflect on the importance of reducing emissions, one of the main causes of climate change. In 2024, global CO2 emissions reached a record 41,600 million tonnes, according to the Global Carbon Budget report, prepared by 120 specialists from more than 80 institutions. This 0.8% increase compared to 2023 underscores the urgent need for more ambitious climate action. If this trajectory continues, there is a 50% chance that the critical limit of 1.5°C will be exceeded in just six years, which would exacerbate the effects of global warming, such as the increase in extreme weather events and the accelerated loss of biodiversity. Despite advances in renewable energy, the growing use of natural gas and oil remains the main driver of fossil-based emissions, which now total 37.4 billion tonnes per year. In addition, changes in land use and deforestation contribute an additional 4.2 billion tons . In this context, it is essential to strengthen the capacity of natural sinks, such as forests and the ocean, which currently absorb about half of the CO2 emitted. However, its effectiveness is being compromised by factors such as deforestation and climatic phenomena. According to the World Health Organization (WHO), air pollution is one of the greatest environmental health risks , causing about 7 million deaths a year due to toxic levels of polluted air. In addition, it points out that 99% of the world’s population breathes air that does not respect the WHO guidelines on air quality, as it contains environmental pollutants in the form of particles that cause health problems (cardiovascular, cerebrovascular and respiratory diseases).

Collective commitment, more urgent than ever

The World Day for the Reduction of CO2 Emissions reminds us that combating climate change is not only the task of governments or large institutions, but a commitment that requires the participation of the whole of society. From taking individual measures, such as reducing energy consumption, to demanding more ambitious public policies and supporting local reforestation and renewable energy initiatives, we can all contribute to reducing our carbon footprint. Reducing CO2 emissions must be a priority on the global and personal agenda. This global day is an invitation to reflect on our impact on the planet and to take concrete action to ensure a sustainable future. As a society, we still have time to make a difference.
