Here is some info from the UN. They take into account a lot of factors beyond carbon output, including acidification of oceans and land use changes. So the 1000 uses is how many uses to be better in all categories. For carbon output, it is around 150 uses.
I guess it depends which categories are more important to you. Plastic is obviously going to be superior in agricultural run-off issues. Cloth is obviously superior in micro plastic emissions. They don’t evaluate microplastics though, so it might be skewed in favour of plastic.

It doesn’t sound like he changed the biblical rules, just opened the doors a bit. So LGTBQ+ people might still go to hell (according to Catholics) but they can go to church and do whatever they do.
The church can rewrite any of the rules though. If it is official, they call it dogma. They consider it a revelation and it becomes a new rule.
