For regular products it is actually the remaining way per truck that accounts for the majority of their footprint. Kinda why I usually roll my eyes when people cry about dirty cargo ships, while likely driving their own personal car. There's so many areas that would be more important to tackle first.

The whole concept of using wood pellets is bonkers though. You're basically using land to grow trees to burn them, which is stupidly inefficient and certainly not sustainable. It's pretty much a form of greenwashing, to give people the illusion of climate neutral energy production (similar to things like bio & e-fuels).
