Not until recently has Dubai ramped up its recycling and green efforts. Because of the city's lackadaisical recycling methods, landfill space is running out. In 2011, it was reported that the average daily amount of trash disposed was 8,000 tons a day. This number would decrease significantly if Dubai took recycling more seriously. In the past, many inhabitants have complained about Sheikh Zayed highway (the United Arab Emirates' longest road into Sharjah) which was known for having enormous amounts of waste that cover the road with a rank odor.In 2012, a study showed that UAE had the third-biggest ecological footprint per capita in the world.
