A team of scientists is proposing a plan to cut Australia's greenhouse gas emissions by injecting carbon dioxide deep underground.The Commonwealth Scientific and Industrial Research Organisation (CSIRO), and Australian Petroleum Co-operative Research Centre (APCRC) are studying the geological disposal of CO2 in the Gladstone-Rockhampton region of Central Queensland which is experiencing rapid industrial growth. The process involves injecting the CO2 in a semi-liquid form into coal seams, depleted oil and gas fields, large voids and cavities, or into unusable or saline aquifers.
