Finnish newspaper Helsingin Sanomat created the HS Climate Pen to challenge policymakers to take action, especially in light of the upcoming UN climate action summit. The HS Climate Pen has ink that's made with carbon dioxide, one of the primary greenhouse gases in Earth's atmosphere.
To create the ink that powers the pen, Helsingin Sanomat worked with VTT Technical Research Centre of Finland to transform carbon dioxide into carbon black that could be used as a color pigment. The body of the pen boasts a 3D-printed design that's made from recycled aluminum and the production process of creating the pen was compensated through Nordic Offset.
Helsingin Sanomat gifted the pen with carbon dioxide ink to G20 leaders as a call for climate action, especially with regards to the Paris Agreement at the UN Climate Action Summit.
