Measures being taken to address the issue of air pollution in major Indian cities, particularly in Delhi, include: 1. Implementation of the Graded Response Action Plan (GRAP) which categorizes measures based on the severity of pollution levels. 2. Stringent regulations for industries, such as the closure of polluting coal-fired power plants and the introduction of cleaner technologies. 3. Encouraging the use of cleaner fuels by promoting the adoption of liquefied petroleum gas (LPG) for cooking and natural gas for vehicles. 4. Imposition of restrictions on construction activities, burning of waste, and firecracker usage during specific periods, particularly during winter when pollution levels peak. 5. Introduction of odd-even vehicle rationing schemes to reduce vehicular emissions. 6. Initiatives to promote public transportation systems, such as the expansion of the metro network and the introduction of electric buses. 7. Monitoring and enforcement of emission standards for vehicles, with periodic vehicle inspection programs. 8. Establishing air quality monitoring stations and real-time reporting of pollution levels to raise awareness among the public. 9. Promotion of awareness campaigns and public participation to encourage individual actions in reducing pollution.
