This might work at the higher end with tech brands and expensive products. People near the poverty line or people with no savings (most people) simply can't afford to do any of this. Sustainable, green, locally sourced = expensive.
It's a good thing to do if you can. But this won't change the world or the corporations generating most pollution. Everyone needs heat and food. Everyone needs power. And most of us, wealthy and poor, don't get to choose who creates our electricity or supplies us with water.
