Al Hilal Bank has announced that it will continue its sustainability efforts of switching off the lights in its branches and offices after working hours and will add a new green initiative in commemoration of World Environment Day on June 5, 2013. Since dimmer screens save energy by as much as 20 per cent, the bank will promote and offer dark-themed backgrounds and screensavers via strategic websites, emailers, Facebook tabs and Twitter links. Through its online campaigns for its ‘Go dark’ initiative, Al Hilal hopes to encourage more organizations and individuals to support simple actions that protect the environment. World Environment Day is celebrated every year on the 5th of June and organized by UNEP - theUnited Nations Environment Programme. This year’s event was held under the theme ‘Think.Eat.Save.’ and was hosted by Mongolia.
