Does UK's Department of Energy Security & Net Zero actually know what its doing?

On the one hand (as previously noted) it's expanded it supply of #carbon #emissions licences, leading UK's 'carbon market' to see a major drop in price(s);

On the other, in internal documents guiding policy it assumes a carbon price at nearly four times this level to make #renewableenergy look comparatively cheap(er) in analysis of policy.

Inconsistency or a internal disagreement about the direction of policy?
