>I thought they're made of renewable lumber and compost better than plastic?
All of which is irrelevant to climate impact. Taking oil out of the ground, turning it into plastic bags, then burying it is carbon neutral, if we ignore the energy required for processing. This is fair because it also takes energy to process pulp to make paper bags. Composting actually causes co2 to be released, so that's actually counterproductive.
