Its not all great, these reusable bags are starting to fill up in landfills. People forget to bring them, or make an unplanned stop to the grocery store to pick up a few things and buy a new bag. Then at home the bags pile up and get thrown out. Many are barely 'reusable', the are crap and don't get used again an get thrown out (my favorite are the ikea bags, they are big and great for groceries - vs many grocery store offerings which are garbage).
Nutshell, it they may not be a net plus for the environment when so many poor quality bags which are more energy/resource intensive to make end up being single-use anyway.
