A rapidly urbanizing city in Kerala is grappling with escalating air pollution, particularly high levels of PM2.5 and nitrogen oxides (NOx), primarily attributed to increased vehicular traffic and burgeoning industrial activities. Which of the following integrated strategies would be most effective for long-term, sustainable pollution control in this scenario?

Accepted Answer

B. Developing an extensive public transportation network, encouraging non-motorized transport, transitioning industries to renewable energy sources, and enforcing stringent industrial emission standards. — Option B offers the most comprehensive and sustainable long-term solution by addressing both major sources (vehicular and industrial) through systemic changes.

Options A, C, and D offer partial, short-term, or less effective solutions, such as merely shifting pollution or relying on palliative measures rather than source reduction.

Answer

A. Implementing strict vehicle emission testing, promoting the use of private electric vehicles, and subsidizing cleaner industrial fuels.
