The busybodies in our government have no problem throwing the poor under the bus to achieve some feel-good goal so they can go home to their mansions at night and feel good about themselves. They're hurting real people.
All this rule changes is the efficiency for NEW wood burning stoves. It doesn't make them even cost any more. It just means they run more efficiently and put out less smoke. Pre-existing stoves don't need to be pulled out or anything.
So for the rural poor that means less cost for heating (or work of chopping wood if you prefer), and less lung disease, for really no increased cost.
Can't see that as a bad thing.
