It’s a sign of the times when the ultra-exotic carmakers veer in a greener direction. In the last twelve months, Ferrari, Bentley, and even Rolls Royce have put forth plans to become more eco-friendly. Now, it’s Lamborghini’s turn.

The company has announced its intentions to reduce CO2 emissions by about a third in the next six years. Officially, it’s a 35 percent decrease by the year 2015. This will be accomplished via a two-pronged approach: one aimed at vehicle design, the other at modifying manufacturing systems.

First off, Lamborghini is actively researching both hybrid and biofuel alternatives for its vehicle line. And though there are no specific details with regards to either option, it is likely that the Italian automaker will unveil concept versions of one or both technologies by next Spring.

In addition, Lambo designers and engineers are developing ways to decrease vehicle mass, improve aerodynamics, reduce friction, and optimize combustion processes. Some of these efforts have already paid off with the Gallardo LP 560-4, a car that has reduced tailpipe emissions by 18 percent. Without, of course, compromising performance.

In terms of operations, Lamborghini is outfitting their Sant’ Agata Bolognese factory with solar roof panels. Due for completion by the end of the year, the photovoltaic system will reduce CO2 emissions by 20 percent.

Another 10 percent reduction in emissions will be achieved by revamping the heating and lighting systems of the facility, as well as increasing insulation.

Overall, the high-end carmaker will spend roughly 50 million dollars over the next several years to make these improvements.

Lamborghini’s efforts are obviously insignificant in the grand scheme of the automotive world – and beyond. Rather, they help to effectively measure the true span of the green car movement.
