Is it the ever increasing vehicles on the road to be blamed or the technology used in them? Technology of cars, trucks, buses etc plays a vital role on the ambient air quality. It is just not the volume of vehicles that take the road but the engine and fuels used by these vehicles that increase pollution. Delhi, the national capital of India has moved to a cleaner Bharat stage IV emission standard. By doing so, it has taken a step ahead to maintain equilibrium with the environment. In spite of this drastic step, the city is unable to reach its goal of decreasing the level of pollution. One of the main reasons is the free flow of traffic from other states that are following Bharat stage III emission norms. The standards differ because the technology and fuel in Bharat stage III is at least 15 years behind stage IV.
Compared to other developing and developed countries of the world, India is using technology and fuel that is 15 years behind the emission standards. While Europe is following Euro VI, which is equivalent to Bharat stage VI norms, Singapore has moved to Euro V emission standard. Sunita Narain, CSE Director General raised her concern as India will aim at implementing the desired standards only by 2017. This delay according to her, will be accountable for the imbalance of ecology in the times to come.
According to the statistics, 3,00,000 vehicles enter Delhi including 80,000 polluting trucks. Also, 1400 vehicles are added to Delhi roads daily. In order to curb the problem, compatible fuels have to be made available throughout the country. Along with that the conge4stion on the streets can be brought down by fast tracking the construction of Eastern and Western expressway. The High speed NCR rail network that was proposed by the UD ministry should be prioritised. Places such as Tughlakabad container and Azadpur fruit and vegetable market that occupy a huge space should be relocated outside Delhi.
The recent move to make the inner-circle of Connaught Place pedestrian friendly had been enormously appreciated. Absence of the heavy traffic that grazed the roads of the inner circle will turn the busy markets into an organised place. Kundli-Manesar–Palwal expressway that aims at decongesting Delhi roads has further added to the relief. The traffic passing Delhi will now be diverted in a way that it will reach its destination avoiding the route of the national capital.
