Yes, we all now the United Arab Emirates love oil. Dubai is not different. Or is it? Recently it let fall its eye on another kind of oil: waste cooking oil. This February, Neutral Fuels LLC made a deal with the municipality to deliver 100% bio-fuel for the municipality vehicles. Waste cooking oil is treated to be used in vehicles without any changes to the engines and it will cost no more than conventional diesel. Using biofuels made from waste oil results in a lower carbon footprint of driving the vehicles. For Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, it is one way to reach his own ambitious plans to make Dubai a sustainable city. Yet, it is not the ideal solution. If they want truly sustainable transportation, they better rethink the transportation system drastically instead of feeding their cars with just another type of oil.
