Since 2007, every year in late March the world celebrates WWF’s Earth Hour with a global voluntary environmental action of switching off the lights. As part of this year’s Earth Hour global celebration slated for March 31 (8.30pm–9.30pm) people all around the globe are invited to participate in a new activity, the ‘I Will If You Will’ activity, which encourages them to make commitments and promise to do something unusual if the others will pledge to take ‘green’ actions’ to save. The new platform, created in partnership with Leo Burnett and launched at youtube.com/earthhour, is open for everyone who wishes to inspire their friends, family and just people around to set personal sustainability goals.

McDonald’s UK has launched a new campaign revolving around the theme of simple or serious conversations that are started over a cup of coffee. With the new promotion dubbed ‘Cups,’ developed by Leo Burnett, the fast food giant focuses on simple moments of everyday life. The company’s, which usually highlights burgers and fries in its campaigns (like it was in the recent ‘Timber v. Farmer’ advert), this time turned to promoting its range of coffees.
