The economic costs of Nepal’s air quality crisis

The Kathmandu Post highlights the escalating air quality crisis in Nepal, which has become an unbearable and routine spring reality. With air quality indices soaring to hazardous levels, the city's inhabitants and its economy are under siege. The article underscores that this is not merely an instance of bad weather but a national crisis with profound and detrimental effects on society's capacity to prosper.

Air pollution is now the leading risk factor for death and disability in Nepal, shortening the average Nepali’s life span by 3.4 to 4.1 years and contributing to between 26,000 and 42,000 premature deaths annually, according to a 2025 report by the World Bank.

The human cost is staggering. Air pollution is identified as the leading cause of death and disability in Nepal, demonstrably shortening the average lifespan and contributing to tens of thousands of premature deaths each year. Beyond the immediate health impacts, the economic toll is substantial, with lost productivity, increased healthcare expenditures, and disruptions to vital sectors like aviation and tourism draining a significant portion of the country's GDP.

The same study highlights that lost productivity through disruptions in sectors of aviation and tourism, paired with healthcare costs and labour loss, drains about 6 percent of the country’s GDP.

Furthermore, the Post argues that failing to address pollution in urban centers like Kathmandu risks undermining Nepal's position in a global economy increasingly reliant on vibrant city hubs. The unique geographical challenge of the Kathmandu Valley, a bowl-shaped basin prone to trapping pollutants, exacerbates the problem, especially during winter inversions. The article stresses that this environmental crisis directly impacts the 'culture of possibility'—the very engine of growth, innovation, and upward mobility that cities are meant to represent, thereby jeopardizing Nepal's future prosperity.

By failing to prioritise mitigating pollution in cities, Nepal risks undermining its position within a global system where prosperity is increasingly urban, concentrated and unevenly distributed.
