Which method is effective in controlling air quality?

Implementing stricter industrial emission limits is an effective method for controlling air quality because it directly reduces the volume of harmful pollutants released into the atmosphere from industrial activities. Industries often contribute significantly to air pollution through the emission of volatile organic compounds (VOCs), particulate matter, and other toxic substances. By enforcing stricter limits on these emissions, regulatory bodies can compel industries to adopt cleaner technologies and practices, thereby improving overall air quality.

Stronger regulations often lead to innovations in pollution control technologies, prompting companies to invest in cleaner production processes or alternative materials that do not pollute as much. Additionally, stricter limits can lead to better compliance monitoring and enforcement actions, which hold industries accountable for their contributions to air pollution. Consequently, with healthier air quality, public health benefits substantially arise, reducing respiratory problems and other health-related issues linked to poor air quality.

Meanwhile, other strategies such as increasing vehicle emissions testing might help reduce emissions from vehicles, but they do not address the broader industrial sources of pollution. Reducing public transport availability can inadvertently worsen air quality since it can lead to increased reliance on personal vehicles. Encouraging more commercial development typically leads to higher emissions due to increased traffic and industrial activity, further deteriorating air quality. Therefore, embracing stricter industrial emission
