I agree, though Nissan is still several steps away from changing over entirely. In the modern world I think the majority of consumers prefer the convenience of social media for quick enquiries, and a simple telephone service for more serious matters. The more simple matters dealt with via social media, the more call centers can concentrate on the bigger issues.

Unfortunately it's not clear, though probably not. From nearly 100% coal power though emissions of any kind are still likely to be higher than the well-to-wheels of an equivalent vehicle.

I know as much as I need to about CO2, and I speak as I find. If there are any inaccuracies in the article you're welcome to correct me, though really I'd suggest taking it up with Grütter Consulting, since the information in the article is based on their study.

The article I sourced this story from had no link to the study itself and unfortunately, Grutter's own website (http://www.transport-ghg.com/eng/Default.htm) has no link to the study so I'm constrained by my source article.
