Not these ones, though. They're certainly going to reduce emissions in the local area, but their solution inherently cannot scale up. Their planes are tiny, and their flights are super short. It's basically as different from regular commercial flights as you can get, while still working with airplanes.
But not a "major" impact. The vastly bigger problem where Harbour Air operates is "real" flights (because it's the YVR area) and cargo shipping (because it's also the port of Vancouver).
And for this area specifically, it'd be nice if we stopped having a giant, uncovered piles of sulphur pellets, full of sulphur powder from being dumped in piles, literally getting dispersed every second there's even the faintest amount of wind. Which, given that it's the pacific north west, is "every second of every day".
