That definitely helps and I don't want to imply otherwise or say that you shouldn't buy green products. But it is nowhere near enough.
For products with no green alternative, what do you expect people to do? How to do you compare the supply chains of products given they are intentionally as opaque as possible.
Everything is shipped over polluting airplanes stored in polluting plastic containers and manufactured with polluting nonrenewable power.
Not to mention there are other ethical concerns to care about. I don't want to support companies with bad labor practices either. But once you filter out the companies doing obviously horrible things the remaining list is terribly short.
And I shouldn't have to worry about this! It's not my job to audit every company. If you can't make a product without shoving externalities on everyone else you shouldn't be making a product, period.
The normal solution people have been hoping for is regulations: a carbon tax makes so much sense, as does outright banning particularly harmful practices like we have with old refrigerants. But this hasn't worked yet, and a wishy washy consumer-driven market solution hasn't worked either
