Air pollution has emerged as a serious and serious issue which needs immediate attention and effective measures. The ambient air quality is rapidly reducing, posing an important risk to the environment and human health. As India rapidly urbanises, industrialises and expands its population, the need for comprehensive methods to curb air pollution has never been greater.
1. Regulatory Measures and Policies
Overview of Air Quality Standards in India
Air quality standards (AQI) are the fundamental basis that provide the regulatory framework for air pollution control. The air quality standard is a description of the level of air quality approved by the regulator. Authority as enforceable. The goal of developing standards is to offer reason for safety. To remove or reduce exposure to hazardous air, to protect public health from the harmful effects of air pollutants, and to guide national/local authorities in pollution management options. The Objective of the AQI is to measure the air quality in different locations based on the concentration of pollutants. a new set of Indian National Air Quality Standards (INAQS) for 12 parameters, which are listed below the table, The first eight parameters in Table 1, have short-term (1/8/24 hrs) and annual standards (except for CO and O3), and the rest four parameters have only annual standards.

We know very well that the climatic changes are getting worse day by day, as per the recent incidences that are occurring all over India. But yes, it will also not be a myth that we are not working on it. People in India are doing their best, but we still need to battle climate change and contribute to the planet’s and nation’s survival. And the best way is to Educate society and work on solutions, not problems.
Governments are working there, and the best example in India is SWACH BHART ABHIYAN. The initiative was taken by the Indian government in 2016, and where we saw people also promoting it, we saw a few changes as well, which will contribute to the environment and make policies and subsidies, as we saw in the aforementioned article.
Individuals are urged to contribute by using cleaner modes of transport, conserving energy, and participating in tree planting drives.
