Air Quality Life Index (AQLI) 2024

Introduction to Air Quality Life Index (AQLI) 2024

The Air Quality Life Index (AQLI) 2024 report was recently released by the Energy Policy Institute at the University of Chicago (EPIC). This index translates particulate air pollution into its impact on human life expectancy, making the invisible threat tangible.

In India, a significant challenge persists: over 40% of the population breathes air exceeding the national annual PM2.5 standard of 40 µg/m³. This highlights the urgent need for robust air quality management.

Key Findings: Impact on Life Expectancy

The AQLI 2024 report underscores the profound impact of air pollution on global life expectancy. It reveals that achieving the World Health Organization (WHO) guidelines for PM2.5 could significantly extend human lives.

Global Scenario: Pollution Reduction and Life Gains

Several regions have demonstrated the effectiveness of stringent environmental policies in combating air pollution and improving public health.

• United States (US): Has achieved a substantial 67.2% reduction in pollution levels since 1970, leading to an average lifespan extension of 1.5 years for its citizens.
• China: Implemented rigorous policies since 2014, resulting in a remarkable 41% decrease in air pollution. This improvement has added 2 years to the life expectancy of the average Chinese person.
• Europe: Has seen a 30.2% reduction in pollution since 1998, contributing an additional 5.6 months to the average life expectancy across the continent.

Regional Analysis: South and Southeast Asia

Despite some improvements, South and Southeast Asia continue to face severe air quality challenges, remaining the most polluted region globally.

• Recent Trends: The region observed a 4% decline in PM2.5 levels in 2022 compared to 2012, indicating some progress.
• Persistent Challenge: Despite this, South Asia alone accounts for 45% of global life years lost due to high pollution, highlighting the immense health burden.
• Most Polluted Countries: Bangladesh, India, Nepal, and Pakistan are consistently ranked among the most polluted nations worldwide.
• Myanmar's Impact: In Myanmar, air pollution is currently reducing life expectancy by an average of 2.9 years.

Regional Analysis: Africa

Air pollution levels in Central and West Africa largely remained unchanged in 2022, posing a significant public health threat.

• Average PM2.5 Concentration: The region's average PM2.5 concentration stands at 22.2 µg/m³, which is 4.4 times higher than the WHO guideline.
• Life Expectancy Reduction: This level of pollution is reducing life expectancy by an average of 1.7 years across the region.
• Emerging Policies: Encouragingly, countries like Nigeria, Rwanda, and Ghana have recently initiated and implemented their own air quality regulations and standards.

Regional Analysis: West Asia (MENA)

The Middle East and North Africa (MENA) region has emerged as a new hotspot for air pollution, with growing concerns about its impact on public health.

• Life Expectancy Reduction: Air pollution in the MENA region is reducing life expectancy by an average of 1.3 years.
• Most Polluted Nations: Qatar and Iraq are identified as the most polluted countries within this region.

Regional Analysis: Latin America

Latin America has experienced a concerning increase in PM2.5 levels in recent years, indicating a deteriorating air quality situation.

• Rising Pollution: PM2.5 levels increased by 4.8% from 2021 and 3% from 1998 in the region.
• Most Polluted: Bolivia is the most polluted country in Latin America.
• Guatemala's Impact: In Guatemala, air pollution is reducing life expectancy by 2.1 years.
• Urban Initiatives: Major cities such as Bogotá, Mexico City, and Quito are actively implementing measures like driving restrictions and improvements in public transport to combat urban air pollution.
