According to the WWF report, the UAE's "Ecological Footprint," which is a measurement of human demand on the environment, is the world's largest, per capita.

The 2006 study was the third report published since 2000 using the "footprint" scale. The UAE has topped the report in each of those years, according to Jonathan Loh, a biologist who co-authored the report.

"Yes, we are one of the largest energy consumers in the world. There should be some awareness of the energy consumption and environment," said Fatima Al Jaber, chief operations officer of Abu Dhabi based Al Jaber Group.

"The authorities should create awareness among the public and try to reduce energy consumption."

The report was published with data from 2003, which was the most recently available, according to Loh.
