As long as the green aspect was mentioned I thought I would share some info.

I delivered a new 8-series to a customer the other day. The customer has a fleet of mostly Toyota 5,000 lb. pneumatics. They also have a 3 month old ale with the GM engine.

They were very concerned with emission since this is a primarily indoor application. They called me over to show me something. They had their CO (Carbon Monoxide) monitor in hand and the Yale and new Toyota were side by side. Both had been used for a few hours and the operators were on break.

They proceeded to show me the CO levels at idle. Both trucks were 4-5 PPM at the tailpipe.

At full RPM the Yale was 130+ PPM and the Toyota was 8 PPM. They gave me an order for 5 more trucks the next day.
