One costly but effective solution is carbon removal technology, which many companies and federal initiatives
The news comes after an April report from the United Nations’ Intergovernmental Panel on Climate Change said that the need for carbon removal is “unavoidable,” if the world hopes to reach global temperature targets necessary to prevent climate catastrophe. The panel hopes to see carbon removal technology use increase a thousandfold within the decade — despite the difficulty in doing so financially, politically and affordably.
Not only does the world need to decarbonize as quickly as possible, explains energy systems engineer Niall Mac Dowell, but the planet will also need to reach negative emissions to make an impact. CO₂ makes up just 0.04 percent of the air, but 10 percent of exhaust gases, and carbon removal costs around 15 times the cost of carbon capture and storage.
Still, carbon removal has just begun to see enough bipartisan support and necessary financial investments, like those from Musk and Alphabet, to begin making things happen. Although carbon removal is more difficult than carbon capture and storage, or trapping gases at the tops of smokestacks and pumping them back into the Earth, the task is set to have a large, much-needed impact that hasn’t happened with carbon capture and storage technologies.
