Greenpeace Analysis On Economic Cost Of Air Pollution

Why in News

According to a Greenpeace Southeast Asia (non-governmental organisation) analysis of cost to the economy due to air pollution, PM 2.5 air pollution claimed approximately 54,000 lives in Delhi in 2020.

  • PM 2.5 refers to fine particulate matter smaller than 2.5 micrometers in diameter. It causes respiratory problems and also reduces visibility. It is an endocrine disruptor that can affect insulin secretion and insulin sensitivity, thus contributing to diabetes.

Key Points

  • Report on Indian Cities:
    • Delhi:
      • In July 2020, Greenpeace found out that of the 28 global cities studied, Delhi bore the highest economic cost of air pollution with an estimated loss of 24,000 lives in the first half of 2020 despite a strict Covid-19 lockdown.
      • In 2020, air pollutant levels in Delhi remained almost six times above the prescribed WHO (World Health Organisation) limits of 10 μg/m3 annual mean.
      • The estimated air pollution-related economic losses were USD 8.1 billion, which amounts to 13% of Delhi's annual Gross Domestic Product (GDP).
    • Mumbai:
      • An estimated 25,000 avoidable deaths in Mumbai in 2020 have been attributed to air pollution from PM 2.5 and Nitrogen Dioxide (NO2).
    • Other Cities:
      • Damage due to air pollution is equally worrying in other cities - Mumbai, Bengaluru, Chennai, Hyderabad and Lucknow - featured in the global analysis.
      • Bengaluru, Chennai and Hyderabad estimated an approximate 12,000, 11,000, and 11,000 avoidable deaths respectively due to polluted air.
  • Global Scenario:
    • Globally, approximately 1,60,000 deaths have been attributed to PM 2.5 air pollution in the five most populous cities — Delhi (India), Mexico City (Mexico), São Paulo (Brazil), Shanghai (China) and Tokyo (Japan).
    • In 2020, the estimated economic cost of PM 2.5 air pollution exceeded USD 5 billion in 14 cities included in the analysis.
    • Tokyo (Japan):
      • Of the included cities, the highest estimated total financial cost from air pollution was recorded in Tokyo, which suffered approximately 40,000 avoidable deaths and an economic loss of USD 43 billion due to PM 2.5 air pollution in 2020.
    • Los Angeles (USA):
      • It recorded the highest per capita financial cost of PM 2.5 air pollution of all cities on the estimator, at approximately USD 2,700 per resident.
  • Indicators Used in Measurement:
    • PM 2.5 Measurements:
      • Real-time ground-level PM 2.5 measurements were collected from different places and combined together in IQAir’s database.
        • IQAir is an air quality technology company.
      • Using Algorithms, such data was applied to scientific risk models in combination with population and public health data to estimate the health and economic costs of air pollution exposure.
    • Willingness To Pay:
      • To show the impact of air pollution-related deaths on the economy, the approach used by Greenpeace is called ‘willingness-to-pay’ — a lost life year or a year lived with disability is converted to money by the amount that people are willing to pay in order to avoid this negative outcome.
    • Cost Estimator:
      • The ‘Cost Estimator’, an online tool that estimates the real-time health impact and economic cost from fine particulate matter (PM 2.5) air pollution in major world cities, was deployed in a collaboration between Greenpeace Southeast Asia, IQAir and the Centre for Research on Energy and Clean Air (CREA).
  • Fatality of Air Pollution:
    • Globally:
      • WHO:
        • According to WHO, toxic air is now the biggest environmental risk of early death, responsible for one in nine of all fatalities.
        • It kills 7 million people a year, far more than HIV, tuberculosis and malaria combined.
      • World Bank:
        • According to a 2016 World Bank report, the lost lives and ill health caused are also a colossal economic burden: USD 225bn is lost labour income in 2013, or USD 5.11tn per year (about $1m a minute), if welfare losses are also added.
    • In India:
      • Overall: Long-term exposure to outdoor and household (indoor) air pollution contributed to over 1.67 million annual deaths from stroke, heart attack, diabetes, lung cancer, chronic lung diseases, and neonatal diseases, in India in 2019.
      • Infant Related Data: High PM contributed to the deaths of more than 1,16,000 Indian infants who did not survive their first month.
        • Infants in the first month of life are already at a vulnerable stage and a growing body of scientific evidence-supported studies in India indicates that particulate air pollution exposure during pregnancy is linked to low birth weight and preterm birth.
