The eco-friendly trend that has hit car makers this past decade is starting to gather more followers, with GM being among the last to join.
To show its support, the US car maker promised that by 2017 they will have twice as many vehicles that are capable of doing 40 mpg or 5.9 liter/100 km.
This announcement is the latest step in a series of improvements that GM implemented in order to be more eco-friendly. Since 2010, GM has also been fitting solar panels all over their installations, managing to reduce their world wide power usage by 7 percent.
In addition to energy saving, Gm is also recycling up to 90 percent of all waste material produced. If the promise to have more eco-friendly cars turns out to be true, the giant will earn the gratitude of many ecologists. Unlike the CO2 emissions imposed on cars by 2020 in Europe, the US seems to be a bit more flexible, giving car makers more room to juggle.
