Carbon emissions in the UK have been dropping since the peak in the 1970s - and are now at a similar level to where they were in the 1880s or thereabouts, despite us all using a lot more energy.
So we will achieve it by doing what we've been doing since then, only more so.
your weird fantasy that climate change is made up to allow the elite to exert more and more control over or lives fortunately has no basis in reality.
