Why is it important to retrofit older vehicles for emissions control?

Retrofitting older vehicles for emissions control is crucial because it addresses the outdated emissions standards that these vehicles might not meet. As environmental regulations evolve, newer vehicles are designed with advanced technologies to minimize pollutants. By retrofitting, older vehicles can be upgraded with similar technologies to reduce the amount of harmful emissions they produce. This improves air quality and public health by decreasing the number of pollutants released into the atmosphere, thus aligning older vehicles with current environmental standards.

The other aspects listed do not directly relate to the primary purpose of retrofitting for emissions control. Luxury features or insurance costs are not the focus when discussing environmental impact, and retrofitting is intended to enhance efficiency and compliance rather than allow for increased fuel usage.
