Taking Greenhouse Gases from the Sky: 7 Things to Know About Carbon Removal

With greenhouse gas emissions climbing and climate impacts becoming increasingly severe, the urgency to address climate change has never been greater.  Many of the solutions to date have focused on mitigation—ways to slash emissions as quickly as possible, such as by adopting renewable energy, promoting energy efficiency and stopping deforestation.  These efforts remain critically important, and we need to accelerate them.  Yet the science shows they will not be enough on their own to have a good chance of meeting the goals of the Paris Agreement on climate change.

To prevent the worst impacts of climate change, the world will need to reach net-negative emissions, a point at which we’re actually removing and storing more carbon from the air than we’re putting into the atmosphere.  This will involve deploying techniques that remove carbon from the atmosphere and permanently store it.

Here, we take a look at the latest science on negative emissions and carbon-removal approaches:
