Continuing with the challenge for a balance towards policies and practices for achieving cleaner fuels in
Among Asian countries; Singapore, Japan, Hong Kong have taken a proactive role towards Euro 4 standards and beyond; followed by carefully planned action plan by India, China and Philippines to adopt Euro 4 standards nationwide. However, still there are many Asian countries like Malaysia, Indonesia, Pakistan and Vietnam that have only road maps for Euro 2, while countries including Bhutan and Cambodia, Nepal, Pakistan and Sri-Lanka do not even have any formal fuel quality or vehicle emissions road maps in place. The planning and implementation for removal of lead from gasoline had been remarkable in the Asian subcontinent. However, when it comes to sulphur levels (Figure 1,2)  there is still a contrast in the approach in the region where countries like Japan switching to ultra low sulphur content and at the same time we have countries still struggling to move ahead and manage with Euro 2 fuel quality standards.
To meet Euro 4 target there are certainly technological and financial hurdles, as fuel quality and vehicles technology is not just domain of one industry rather it’s a business preposition of different stakeholders. Whenever we talk about cleaning up vehicles in developing countries, we need to consider and understand role of various technologies and requirement of fuel quality to achieve the end motive of cleaner environment. Besides, cleaner fuels will have a better impact with both new and old generation of vehicles to reduce emissions. There is indeed a price for the incremental costs, estimates show that for meeting fuel sulfur in Asia would cost 0.2-0.8 US cents/L for gasoline and 0.5 – 0.8 US cents/L for diesel, with additional 0.6 cents/L for further reductions to 10 ppm or below for diesel fuel . However, going back to the rationale of cleaner fuels for better environment and public health, there is a time to plan and act now. The path to reach cleaner fuels may be complex but at the end of day if we see the long term benefits; there is certainly a call to keep the marathon on towards achieving cleaner fuels…because it is ultimately us who has to take the decision….
