What does the "carbon stack" typically comprise for an ecommerce company or marketplace on Patch's platform?

It depends on what you're trying to do. If you’re trying to get to net-zero, you need some sort of carbon accounting provider to give you the ability to report or reduce your emissions, and you need a carbon credit provider. That's something like Patch—or you can access Patch through one of these other integrated systems. Those are the two major pieces. That's truly the lowest common denominator. 

Then there are these other data monitoring systems that we’re actually in the process of folding into Patch, companies like Sylvera or BeZero, which provide an extra level of data and resolution on the underlying carbon projects. They're trying to be like the Moody’s, if you will, of carbon.
