Climate stabilization wedge

Climate stabilization wedges are used to describe possible climate change mitigation scenarios and their impact, through the grouping of different types of interventions into "wedges" representing potential decreases in CO2 emissions. When stacked on top of each other, wedges form a "stabilization triangle" that represents the estimated amount of carbon that needs to be removed from the atmosphere to flatten carbon emissions and prevent atmospheric carbon from doubling.
