vishkap financial accountability is necessary, but I don't understand how a loan can be different.
Klima has requested more than once the budgets for building. The request now is a bigger budget (less future requests therefore), and provide a real world entity that has the possibility of accepting more and bigger clients.
The idea, is of course to be as more decentralized as possible, and there it's clear and shown in the past months with for instance QV and other moves.
The split will allow the protocol to focus 100% on the protocol itself, and allow carbonmark to build the infrastructure where Klima will benefit, and the infrastructure that so far Klima doesn't have and need (rw entity).
On the other hand, the difference is truly minimal
