The all-electric Nissan Leaf EV is available in the U.S. but Nissan plans on releasing a plug-in hybrid by 2016.  This is part of the "Nissan Green Program 2016" or NGP 2016. The goal of this program is to reduce the company's carbon footprint, as well as shift to renewable energy.

"Nissan wants to be part of the solution toward a sustainable society - for the sake of the planet and as a significant competitive advantage and a strategic differentiator in the global manufacturing sector," said Nissan President Carlos Ghosn.¹

Future models from the Japanese auto maker are part of this strategy, which includes the improvement of corporate fuel economy by 35%, compared with 2005 levels that are much lower. Nissan will launch vehicles designed, and upgrade class-leading fuel economy across the range of vehicles in the US, Europe, China and Japan.
