Global Conference on Air Pollution and Health 2025

The second Global Conference on Air Pollution and Health is currently taking place in Cartagena, Colombia. Organised by the World Health Organization (WHO) and the Colombian government, the conference aims to galvanise global support to halve deaths from air pollution by 2040 compared to 2015 levels. Air pollution claims nearly seven million lives annually, with the most severe impacts felt in developing nations. The conference marks the urgent need for legislative action, public awareness, and community engagement to combat this public health crisis.

Air Pollution Statistics and Impact

Air pollution is a leading cause of premature mortality worldwide. About 2.1 billion people die due to energy poverty. Nine out of ten individuals breathe air that fails to meet WHO standards. The economic toll of air pollution is staggering, estimated at $8.1 trillion, equating to 6.1% of the global GDP. Children are particularly vulnerable, with 2.7 billion under the age of 15 exposed to unsafe air quality.

Health Consequences of Air Pollution

Air pollution affects nearly every organ system in the human body. Pollutants can cause oxidative stress and inflammation. They have been linked to cognitive decline and mental health issues, including anxiety and depression. The prenatal and early childhood stages are critical, with evidence showing increased risks of neurodevelopmental disorders.

Legislative and Policy Measures

The conference puts stress on the need for robust legislation to enforce WHO guidelines. Political will is essential for implementing effective air quality measures. The role of city mayors is very important in aligning local actions with global climate goals. Coordinated efforts between health and environmental sectors are necessary for impactful policy changes.

Energy Transition and Its Importance

Transitioning to clean energy is vital for reducing air pollution. A Lancet study marks a 6.9% decrease in deaths from fossil fuel-related air pollution. The reduction is largely attributed to decreased coal usage. Strategies targeting black carbon emissions are critical, as they pose health risks.

Addressing Energy Poverty

Energy poverty remains challenge, particularly for low-income households. Despite initiatives like India’s Ujjwala programme, many still lack access to clean energy. Investment in clean energy solutions is crucial to ensure equitable access and improve air quality.

Community and Personal Stories

The conference also shares personal accounts of those affected by air pollution. Stories like that of Rosamund Adoo-Kissi-Debrah, who lost her daughter to asthma, highlight the human cost of inaction. Medical professionals also shared their observations, reinforcing the need for urgent change.

Global Collaboration and Action

The conference promotes collaboration among scientists, policymakers, and community leaders. Cities are encouraged to implement air quality policies and share best practices. Collaborative efforts can lead to improvements in air quality and public health outcomes.
