Is the Ban on 10-year-old Diesel Cars Justified?

The recent decision by the Delhi government to deregister diesel cars older than 10 years, effective from January 2022, has sparked debate among environmentalists, automotive enthusiasts, and policymakers. This move has been taken in the wake of rising pollution levels in the National Capital Region (NCR). The question of whether such a ban is justified is multifaceted and requires careful consideration.

Context and Impact

The announcement by the Delhi government, in line with the National Green Tribunal (NGT), underscores the growing concern over air quality in the region. While the decision may seem impactful, it is essential to examine the broader implications and necessary conditions for such a ban to be effective.

The Validity of the Ban

There is a significant debate about whether a ban on 10-year-old diesel cars is justified. Critics argue that a blanket ban is not necessary for countries where employment is a major issue or where economies are still developing. Alternatives, such as stringent emission checks, phased implementation, and incentives for transport operators, are proposed as more practical solutions.

Improving Maintenance and Emissions

Another argument against a total ban is that many diesel car owners do not maintain their engines properly, leading to excessive pollution. A well-maintained diesel car can perform as efficiently as a new one, emitting less harmful pollutants. The need for stringent emission checks and proper maintenance cannot be overlooked. Some argue that newer diesel engines are compliant with stricter norms, thereby reducing pollution.

Modular Design and Registration Validity

Another perspective involves the modular design of modern vehicles. Vehicles can be brought back to near-original condition through the replacement of a few components. It is highly illegal and impractical for the government to reduce the registration validity of vehicles without proper justification. Suspected vehicles should be subjected to rigorous inspection procedures.

Impact on Society and Environment

A ban on 10-year-old diesel cars would not be justifiable unless it significantly reduces air pollution. New cars, designed to meet modern pollution norms, might still pose a burden on the environment. The promotion of car ownership at the expense of public transportation and infrastructure is itself detrimental to ecological health.

Alternatives to a Ban

Instead of a ban, a phased approach could be beneficial. For instance, the government could set a timeline—such as 20 years for older vehicles, 15 years for mid-aged ones, and 10 years for newer ones—and offer incentives to transport operators and users. This could encourage more responsible ownership and maintenance of vehicles.

Conclusion

The justification for a ban on 10-year-old diesel cars hinges on several factors, including the level of pollution reduction, the number of affected vehicles, and the overall impact on society and the environment. While a blanket ban may seem drastic, it is essential to consider alternatives that balance environmental concerns with economic and social needs.
