I want you to think about how many leaf blowers are actually being used, and how many hours even the most inefficient small engine would have to run to compare to a single semi-truck route.

It's so incredibly fucked how you people miss the forest for the trees.

So I promise I'm not trying to be a dick here. While what you're saying is essentially reasonable, it's actually not true.

The amount of emissions in these small, wildly inefficient engines is considerably worse than even a large pickup truck. The reason is because emissions standards, including the introduction of catalytic converters, etc. don't apply to lawn equipment. The result is that these don't actually burn fuel correctly, and spew out lots of harmful pollutants in a way that even large ICE vehicles don't.

Like sure, there are larger sources of emissions, but I'm kinda in favor of making changes that would offer a large benefit proportionate to the amount of lifestyle change needed to make the switch. As in, making this switch would be easier than not. These emissions produce no benefit to us, and they cost us a weird amount of money to produce.

So I promise I'm not trying to be a dick, but do you actually understand the results from the articles you posted?

A basic mass balance on the claims implies a very narrow interpretation of "emissions". It doesn't even pass the most basic sniff test, come on.

Not only do those articles completely ignore CO2, what about the energy required to manufacture and transport the fuel in the first place?

Those studies focus on NOx emissions, a very small subset of overall environmental impact. They basically cherry pick the fuck out of what consitutes as an "emission", and ignores the massive difference in greenhouse gasses produced.

There are claims that running a leaf blower for 30 minutes produces as much "emissions" as driving a Raptor like 1 thousand miles.

Lmao, if you think a quarter gallon of gas from the leaf blower is "worse" than 100 gallons of fuel the truck would burn, you have to be mad.

Think about it for more than a couple seconds.

And even funnier about this, the solution for this shit is already here. Aside from commercial landscaping companies, electric is already taking over. Its basically a non-issue as far as realists are concerned.

This is an alert from the Summer's Eve Emergency Broadcast System. This is not a test. I repeat, this is not a test.

Reddit has experienced a Level Spez douche release which impacted Lemmy.world approximately 96 hours ago. Lemmy users may observe increased douche activity, including but not limited to: unjustified smugness, irrelevant and erroreous corrections, bad arguments, ego fragility, unwarranted hostility, and assorted douchebaggery. Users are advised to remain calm, refrain from engaging encountered douches in serious conversation, and to liberally use the block feature.

Do you have any solid information to provide or are you just making vague allusions toward some unsubstantiated assumptions so you can justify to yourself being a judgmental ass?

It's so incredibly fucked how "you people" are judgmental shits who are busy jerking yourself off every time you can "well ackshally" someone.
