Have a read on this:
Even if we take industry’s claims at face value, nothing is keeping fossil-fuel companies from more drilling on public lands right now. The oil industry already controls at least 26m acres of public land and is sitting on more than 9,000 approved drilling permits they’re not using.
They have a similarly gratuitous surplus offshore, where nearly 75% of their active federal oil and gas leases, covering over 8m acres, have yet to produce a single drop. Any new leases issued today wouldn’t produce anything of value for years, or even decades in some cases.
In other words, the oil industry has the land already and they’re not using it. This is by choice, I surmise, to keep prices and profits high.
