Electric cars produce far less brake dust pollution than combustion-engine cars

I didn't quite get if you think changing gears for the purpose of engine braking wears the clutch more than normal or not. Are you using the force from the clutch to force the engine to go from a low RPM to a high RPM? In cases like that where the difference in RPM is significant, I would press the clutch pedal, then speed up the engine by pressing the gas pedal, downshift, then release the clutch. Rev matching, basically. It does wear the clutch a teeny tiny bit, but not more than any other gear change.

If your comment wasn't meant to imply that engine braking wears the clutch more than normal gearing, if you just want to avoid gear changes as much as possible, disregard this comment. (Although... I'm not sure that that's a valid worry, modern clutches last a LONG time when used properly)

You might not execute the rev-match perfectly every time, esp if you're doing a heel-toe. I think it's also harder on the synchro.

Sure, and I definitely don't rev-match close to perfect every time. I'm just saying you don't have to use the clutch to accelerate your motor all the way from minimum RPM, which it sounded like my parent comment might be suggesting

I think that suggestion was that you're holding the clutch pedal in longer while you bring up the RPMs, compared to upshifting which is faster. The clutch does wear a bit even when "fully" disengaged. But I don't think it matters enough here, just don't leave it like that during a red light.
