I assume you mean:

https://www.epa.gov/sites/production/files/2015-09/documents... (2015)

"All Nonroad sources account for approximately 242 million tons of pollutants each year, accounting for 17% of all VOC missions, 12% of NOx emissions, 29% of CO emissions, 4% of CO2 emissions, 2% of PM10 emissions, and 5% of PM2.5 emissions."

What's "Nonroad" isn't clearly defined here, so I assume it's quite a lot more than "Gas-powered blowers".

page 7 and figure 2, "GLGE represented nearly 4% of All Emissions of VOCs and 12% of All Emissions of CO"

Carbon Monoxide (CO) does not cause climate change. (https://climate.nasa.gov/news/2291/fourteen-years-of-carbon-...)

It's dangerous to humans in closed spaces, but that's not where leaf blowers are operated. (And yes, I also hate them, but that's not he point.)

So then I can only assume you included the carbon monoxide number because it was ... large?

it's a pollutant, and the primary pollutant of gas lawn equipment.

It includes boat motors.

I expect the non-particulate emissions are dominated by 2 stroke motors (well, other than COâ‚‚).
