An Overview of Carbon Sequestration

What is carbon sequestration?

Carbon sequestration, or carbon capture and storage (CCS) is the process of taking carbon dioxide out of the atmosphere and storing it. CCS is a critical part of the solution suite for limiting global warming to1.5°C above pre-industrial levels. The Intergovernmental Panel on Climate Change (IPCC) includes CCS in 3 out of its 4 pathways to 1.5°C. CCS can allow for a more gradual and therefore easier path to decarbonization.

What does the future hold for carbon sequestration?

Today, there are only 26 operational commercial CCS sites in the world. These sites capture 40 million tons of CO2 a year — good progress, but far short of the 50 billion tons that we emit each year.
