The world cannot be saved if we reduce carbon emissions to zero. We also need to remove carbon from the air – a massive undertaking, the likes of which we have never done before. Over the last few centuries, we have added 2.4 trillion tons of carbon dioxide to the Earth’s atmosphere. Davide Monteleone has made several trips across Europe to visit some of the leading facilities in the field of CO2 capture and storage. He photographed how large machines suck CO2 out of the air, plants where carbon dioxide is injected underground and submarine tanks that allow us to store it under the seabed. Some companies have found a way to recycle CO2, and others are growing microalgae to absorb it.
