That's sort of the point of carbon pricing. The idea is to give companies incentives so they allocate resources to the development of new technologies. In any case, they are in the best position to do that.
It's often difficult for governments to pick winners and losers, to know which technologies to support and which not to support. So let's take advantage of the industry's expertise, give it the incentives in the form of credits it could generate in the system, and let it invest its own funds.
