The breathable barrier is designed to stop CO2 emissions right at the source. Utilizing a honeycomb system of interconnected moss, which survives by absorbing nutrients and water from the air, the panels act as a filter and collect emissions particles before they can make it into the local environment. Capable of being integrated onto the existing transportation infrastructure, the green moss also makes for a stunning visual and triples as a padded sound absorber to keep road noise to a minimum. This design is a winner of the 2018 . Designers: Hsuan Ting Huang & Tsung Ying Hsieh
