How can large amounts of CO2 be used positively to return the levels to normal?
A. CO2CRC and other organisations are researching alternative uses for CO2. But the industrial sources of CO2 are so large that a portfolio of solutions is needed to achieve deep cuts into greenhouse gas emissions. Australia alone emits 560 megatonnes of CO2 each year, half of which is emitted from power stations. Reducing greenhouse gases requires a portfolio of responses including increasing energy efficiency; switching to less carbon-intensive fuels; biological sequestration; and harnessing renewable energy from the wind, sun and tides as well as geosequestration.
