Whatever might be the actual cause, i.e. scientific, political, or health advisory, the truth is that since the National Lockdown or Janta Curfew that began from 24th March 2020 and continues till 17th May 2020 our environment took a breather. We human beings have finally begun to learn our lesson. Just by staying home, we have managed to reduce a few but a considerable percentage of our carbon footprints. We now see clear blue skies, improved Air Quality Indexes, cleaner water bodies across the globe.
Before going further, one may ask what is Carbon Footprinting? And why is it so important to limit it? To get your answer, click here
The major sectors contributing to the increase in our carbon footprints are transport, industries, power plants, construction activities, biomass burning, road dust resuspension, and residential activities. In addition, landfill fires, deforestation are other major causes of the rapid growth of carbon footprints that also contribute to air pollution.

Air pollution is one of the world’s most dangerous health risks, as it kills seven million people each year according to the World Health Organization. Studies show that in comparison to tobacco, smoking reduces life expectancy by an average of 2.2 years, HIV / AIDS by 0.7 years, and other vector-borne diseases such as malaria — by 0.6 years, air pollution reduces life expectancy to 2.9 years. Air pollution is majorly caused by the excessive emission of carbon dioxide — the gas most commonly emitted by humans — and others, including methane, nitrous oxide, and fluorinated gases, which trap heat in the atmosphere.
The COVID-19 pandemic has caused shut down to industrial activities and cancelled flights and other journeys, cutting down the greenhouse gas emissions and air pollution around the world. If there is something positive to take from this terrible crisis, it could be that it’s offered a taste of the air we might breathe in a low-carbon future.
India’s Central Pollution Control Board (CPCB) has recently reported an improvement in air quality in the country. The data suggests a nearly 71% fall in nitrogen dioxide levels due to the sharp drop in fossil fuel combustion after the lockdown in the above sector. Ghaziabad the major polluted Indian city of 2019 closely followed by Greater Noida, Noida, and Bulandshahr that have witnessed severe air quality conditions with crossed the 400 marks of the Air Quality Index (AQI) on several occasions which are improved with a recorded range of 60 to 100 AQI.
