ADAGE - Apr 15 - OkCupid has launched its first-ever global badge in honor of Earth Month. The new Climate Change Badge lets users add a "Climate Change Advocate" designation to their profiles by answering "Yes" to the question "Do you want a profile badge to show you care about climate change?" The badge only formally launched on April 8, but already, 9 out of 10 users have opted in. The company is donating $25K to EarthDay.org as part of the initiative. Users with the badge are getting 44% more likes and 72% more matches than non-badged users, according to OKCupid's latest data. They're also having 27% more conversations than non-badged users.
