For the environmentally minded, clearly the monster truck is the way to green nirvana.................

I like things like that, whether accurate or not at least it shows it's not a simple as the green nimbys would have you think!

Yes. Leafblowers don't have emission controls, and the US fuel economy test is a lot more indicative of every day driving, meaning it can't be "gamed" with silly gear ratios and throttle mappings like the EU one can.

The cars put out less CO because they have a cat that turns the CO into CO2.
I'm sure if you compred the CO2 output of blowers vs. cars then you'd find the cars CO2 to be many many times that of the blower.

The only way to make a sensible comparison would be to give each emission type a "weighting", reflecting how bad a gram of that element is relativly to the others, and produce a weighted score. (For example each gram of CO may score 10 points, but a gram of CO2 only say 1 or 2 points or something because CO2 is less bad for the environment than CO.) The get the total for each engine and compare that.

yes In this test the measurements of NOx, CO, HC etc. are a percentage of the overall volume of exhaust. The leafblowers are 'dirty' in the sense that a greater percentage of their exhaust comprises of harmful emissions, but there will be far less total volume of exhaust than the 6.8L Raptor.

What they said. As much bks as the 'survey' that indicated a Hummer was more environmentally friendly than a Prius.

The guy seems to be focusing on hydrocarbon emissions.

Test figures show 149g/km for a Fiat 500, and 387g/km for a 6.2 Ford.
