sustainmovementApple launched a new app campaign yesterday in an effort to expand their environmental efforts. The new campaign, similar to 2014’s Apps for (RED), is called Apps for Earth.

Apple started this campaign in conjunction with the World Wildlife Fund (WWF), and from April 14-24 100% of paid-app and in-app purchases will go to the WWF. Apple’s app developers have created 27 different campaign-related versions of popular apps, including games, photo editing and other utility apps.

The new environmentally-conscious campaign will extend beyond the app store to both Apple.com and Apple retail stores.
