Climate change bringsĀ detrimental consequences on the environment, society, and public health are amply supported by the facts. One of the most harmful effects of climate change is air pollution, which has been linked to cancer, heart disease, and respiratory disorders.

Yet, a current study funded by the National Institute of Environmental Health Sciences (NIEHS) shows that reducing greenhouse gas emissions can have a significant impact on air quality and human health.

Human Health and Air Quality

The WHO estimates that air pollution contributes to seven million avoidable deaths per year and is a substantial environmental risk factor. Outdoor air pollution is a factor in lung cancer, stroke, cardiovascular disease, and respiratory conditions. Fine particulate matter (PM2.5), one of the most hazardous contaminants, can significantly improve people’s health if its airborne concentration is reduced.

Emissions of Greenhouse Gases and Air Pollution

Two greenhouse gasses that are regarded to be the main contributors to climate change are methane and carbon dioxide. Their influence is due to human activities like the burning of fossil fuels or industrial processes that release these gasses into the atmosphere. These sources might also produce other air pollutants, leading to poorer air quality, in addition to greenhouse gasses.

For instance, burning fossil fuels releases carbon dioxide as well as PM2.5. So, by reducing air pollution, reducing greenhouse gas emissions also contributes to improving air quality.

The Advantages of Reducing Greenhouse Gasses

Reducing greenhouse gas emissions can greatly improve air quality and human health, especially in heavily populated areas like South and East Asia, North America, and Europe. By 2030, the benefits of reducing greenhouse gas emissions in China and East Asia will outweigh the expenses 10-70 times over. The results show how important it is to reduce greenhouse gas emissions for the sake of public health in general.

According to research, reducing greenhouse gas emissions can enhance both air quality and human health. The research urges taking prompt action to take advantage of these benefits, which are more economical than expected. Thus, reducing greenhouse gas emissions is crucial for halting climate change, protecting lives, and improving air quality.
