Do you believe a religious metaphor to be useful for understanding climate change?
Do you believe adding CO2 molecules to the air to be intrinsically sinful with the result that no amount of subsequent removal of CO2 can wash away the sin?
The problem isn't on the buyer side. It's that the seller is inherently going to break his promises and defraud you for a penny.
But my main point is that global warming is eminently amenable to technical solutions similar to how for example putting humans on the moon was eminently amenable. Not all societal concerns are so amenable, but for those that are, it seems to me very suboptimal to resort to analogies with religious concepts in public discussions of the concern.
My first comment has a score of -4 now by the way.
Also, I would have hoped that we could have managed to solve the pollution issue in a rational way, but hope is getting thin. And religion comes with the power of strong taboos that might succeed where we previously failed. Or maybe what is blocking us is how progress has been given the status of a new religion, and while we can appreciate where it got us, we also have to consider whether the costs aren't going to outweigh the benefits in the future...
