Assessing carbon removal pathways, their potential, barriers and policy options to accelerate development as part of a suite of climate actions.
Since the Industrial Revolution, humans have emitted more than 2,000 gigatons of carbon dioxide into the atmosphere. (A gigaton is one billion metric tons.) This thickening blanket of heat-trapping greenhouse gases is the cause of the global warming we are experiencing today. If nothing changes, climate impacts such as forest fires, stifling heat waves and damaging sea level rise will only continue to intensify.
