Talking about the report findings, Avinash Chanchal, Climate Campaigner at Greenpeace India said,

While many cities including Delhi have recorded marginal improvements in air quality due to lockdowns, the health and economic cost of air pollution remains severe. It is pertinent that governments prioritize sustainable and clean energy sources, as well as the cities, need to encourage low cost, active and carbon-neutral mobility choices such as walking, cycling, and accessible public transport.

He further said,

Speeding up the transition to clean energy and clean transport not only saves lives but also dramatically reduces healthcare-related costs.

On the other hand, cautioning people and authorities about the rise in air pollution in the year 2021, CEO of IQAir Frank Hammes said,

The year 2020 brought an unexpected dip in air pollution. In 2021, we will likely see an increase in air pollution due to human activity, again. We hope this report highlights the urgent action that needs to be taken by the authorities to combat air pollution, which remains the world’s greatest environmental health threat.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene
