Geological solution to a global issue

03 October 2001


Dr John Bradshaw from AGSO - Geoscience Australia will present the geological solution to the global issue of carbon dioxide (CO2) emissions at the Geoscience Australia open day this Sunday at 1pm.

Dr Bradshaw says there has been a 15 per cent increase in the volume of CO2 in the atmosphere since 1960, which is widely attributed to emissions from man made sources. The increase is believed to produce a greenhouse effect, which is contributing to global warming.

"On a per capita basis Australia is among the highest emitters of CO2 in the world," said Dr Bradshaw.

Dr Bradshaw will discuss the options available to Australia to reduce its CO2 emissions highlighting the geological solution of sequestration.

Sequestration occurs when the CO2 is captured, separated and safely disposed of or 'sequested' into the Earth's geological strata at depths greater than 800 metres, where it will remain trapped for many tens of thousands of years.

Sequestration will have an immediate impact on CO2 emissions and assist in defraying the costs of abandoning existing facilities such as coal fired power generation plants. Research done by Geoscience Australia has identified that sequestration could enable Australia to dramatically reduce its CO2 emissions.
