Already the most environmentally friendly method of transportation, mass transit is about to get a bit friendlier. In two years, Poland will start rolling out subway cars that are 97.5 percent recyclable and super energy efficient thanks to a partnership between Siemens and BMW Group DesignworksUSA, a Los Angeles-based BMW subsidiary.

The Inspiro, seen in the video believe, features an aluminum chassis that is significantly lighter than traditional subway cars. Siemens is also touting demand-controlled air conditioning and an electrodynamic breaking system. All of these features combine in a car that runs on less energy than traditional subway vehicles; officials hope it will reduce energy consumption by as much as 30 percent.
