It doesn't even come close:
While many people think this is a new technology, it’s not. In fact, the US Department of Energy spent at least $6 billion over two decades on it. Not to mention the tax credits oil and gas companies have received for pilot projects.
Even the biggest projects stretch to absorb a few thousand tonnes of carbon dioxide. Meanwhile, we emit over 50 billion tonnes of greenhouse gases each year. That’s a million-fold gap. So, even if artificial carbon removal scaled 1,000x — which is still years and billions of dollars away at best — it would need to grow by another 1,000-fold even to be a small percentage of the solutions we need.
Understand, we could never even come close to the level of carbon capture that naturally exists on our planet. Trees and ocean life, such as seaweed and plankton, absorb a substantial amount of atmospheric carbon, while also producing oxygen. But this isn't just a boondoggle, it's actually a boon for fossil fuel companies:
