Environment Minister Keit Pentus-Rosimannus has said that Estonia is currently using its oil shale resources primitively and that a future use could be more lucrative.
Pentus-Rosimannus said that producing oil from oil shale triples the value of the resource while the production process emits only half as much CO2 as burning the shale for heat or electricity, uudised.err.ee reported today.
“What knowledge, skills and technological developments are at our disposal in 2040 or 2050 is very hard to predict,” she said.
Eesti Energia CEO Sandor Liive said at an energy conference in September that Estonia should use up all of its oil shale resources as quickly as possible, as EU's climate policies will, in 30 to 40 years, render the resource worthless.
Economy Minister Juhan Parts said in June that the state should weigh the risks and benefits of increasing the mining of oil shale.
Pentus-Rosimannus said that Estonia's nature could not handle an increase in the current 20-million-ton annual mining limit.
