Global carbon emissions from fossil fuels continue to rise<\/a> and 2024 is likely to be the world\u2019s hottest year on record<\/a>. <\/p>\n\n

It\u2019s becoming increasingly clear that limiting global warming to 1.5\u00b0C 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<\/a>. <\/p>\n\n

The Intergovernmental Panel on Climate Change (IPCC) says carbon dioxide removal technology will be required<\/a> to achieve global and national net zero targets. In other words, there is no net zero without CO\u2082-removal, because emissions of greenhouse gases are not declining anywhere near fast enough<\/a>.<\/p>\n\n

There will be trade-offs, as CO\u2082-removal can be costly and often uses up energy, water and land<\/a>. But Earth is hurtling towards a climate catastrophe, with more than 3\u00b0C of warming<\/a> 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\u2019s left.<\/p>\n\n

Within the international scientific community<\/a> the debate about carbon dioxide removal has moved on from \u201ccould we, should we?\u201d to \u201cwe must\u201d \u2013 recognising the urgency of the situation. So it\u2019s 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\u2019s net-zero future. <\/p>\n\n
