Groen is a Belgian political party representing Green politics in Flanders. Yesterday, January 11, it unveiled a new party logo along with the the tagline Werkt voor iedereen, meaning "Works for All".
The previous logo was allegedly introduced eight years ago. It included an exclamation mark that has been removed with the new logo, as it wasn't seen as fitting a party that aims to be moderate and listening, and has established itself as a movement which is "here to stay".
And yes, it has already been pointed out that the new logo is very similar to similar to the Groupon logo.
