Japan underground
Japan may bury carbon emissions underground, according to this news report.
“A proposal to bury 200 million tons of carbon dioxide a year by 2020 - cutting the country’s emissions by one-sixth - is under study, Masahiro Nishio, an official at the Ministry of Economy, Trade and Industry, said on Monday.

Tackling carbon dioxide is a priority for Japan, the world’s second-largest economy. It expels 1.3 billion tonnes a year, making it one of the world’s top offenders, despite being a key driver behind the Kyoto Protocol. Underground storage could begin as early as 2010, but there are still many hurdles to overcome, Mr Nishio said.
Capturing carbon dioxide and injecting it underground is prohibitively expensive, costing up to $US52 ($70) a tonne, Mr Nishio said. The ministry aims to halve that cost by 2020. Safety concerns must also be addressed to ensure that earthquakes or rock fissures do not allow a sudden release of millions of tonnes of carbon dioxide.”
