"Global carbon emissions from fossil fuels continue to rise and 2024 is likely
to be the world’s hottest year on record.
It’s becoming increasingly clear that limiting global warming to 1.5°C will
require much more than existing efforts to reduce emissions and decarbonise
industry. We also need to remove enormous amounts of carbon dioxide from the
atmosphere, 7-9 billion tonnes a year.
The Intergovernmental Panel on Climate Change (IPCC) says carbon dioxide
removal technology will be required to achieve global and national net zero
targets. In other words, there is no net zero without CO₂-removal, because
emissions of greenhouse gases are not declining anywhere near fast enough.
There will be trade-offs, as CO₂-removal can be costly and often uses up
energy, water and land. But Earth is hurtling towards a climate catastrophe,
with more than 3°C of warming under current global policies. We must do
everything we can to avert disaster, which means slashing emissions as much as
we possibly can, and removing what’s left.
Within the international scientific community the debate about carbon dioxide
removal has moved on from “could we, should we?” to “we must” – recognising the
urgency of the situation. So it’s worth coming up to speed on the basics of
carbon dioxide removal technology, both old and new, and the role we can expect
it to play in Australia’s net-zero future."
