The Indian government has taken several measures to combat air pollution in major cities. Some of the key measures include:

• The implementation of the National Clean Air Programme (NCAP), aimed at reducing pollution levels by up to 30% by 2024.
• The introduction of the Bharat Stage VI emission norms, which aim to reduce emissions from vehicles by up to 80%.
• Banning the use of pet coke and furnace oil as fuel in industries operating in the National Capital Region (NCR).
• Encouraging the use of public transport, including the introduction of electric buses and the extension of the metro network in major cities.
• Enforcing stringent regulations on construction sites to control dust and other pollutants.
• Promoting the use of clean energy sources, including solar and wind power, and the development of green industries.

These measures, along with others, are expected to improve air quality and reduce the adverse health impacts of air pollution on people living in major Indian cities.
