Why the International Day of Clean Air for Blue Skies Matters

Clean air is a mixture of nitrogen and oxygen, comprising about 78% and 21% of the atmosphere. It is pollutant-free, with a balanced humidity level, and without offensive odors or harmful gases.

When these criteria are not met, poor air quality can cause a two-fold problem. First, it leads to various health issues, such as strokes, heart disease, lung cancer, and respiratory infections. Moreover, air pollution amplifies global warming through pollutants like black carbon and methane.

The International Day of Clean Air for Blue Skies builds upon the importance of clean air for human health and the environment.

Data and Statistics

The World Health Organization estimates that approximately 99% of the global population in 2019 will reside in areas where air quality does not meet WHO standards.

Moreover, the WHO reported approximately 7 million people die prematurely each year due to air pollution due to stroke, heart disease, and respiratory conditions.

The World Bank estimates that the world spends over $225 billion annually on air pollution deaths.

How to Create Clean Air

  • Regularly maintain and service vehicles to ensure they do not emit excess pollutants into the atmosphere.
  • To reduce greenhouse gas emissions, limit the use of private vehicles and encourage public transportation, cycling, or walking.
  • Plant and care for trees and plants in personal spaces and communities. They absorb harmful pollutants and produce oxygen.
  • Conserve energy by using energy-efficient appliances, reducing electricity consumption, and using renewable energy sources to reduce the burning of fossil fuels.
  • Reduce waste by recycling and composting, and avoid burning trash, which releases harmful toxins and particulates into the air.
  • Lobby policymakers to invest in air quality measures.
