| Abstract |
About two decades ago, an idea was proposed to visualize the amount of carbon dioxide (CO2) emission that must be mitigated over the next 50 years to plateau its atmospheric abundance (1). Put forward was a stabilization triangle divided into seven equal wedges, each representing the amount of carbon emissions that can be reduced by existing technologies. However, a decade later, when the 2015 Paris Agreement was adopted, climate goals shifted from fixing carbon emissions at a constant level to achieving a balance between the amount of anthropogenic greenhouse gas put into and removed from the atmosphere (net zero). Technologies have also advanced, and mitigation approaches now span many sectors. On page 1009 of this issue, Johnson and Staffell (2) report an updated framework of modernized wedges that maps out 36 decarbonization strategies. This construct allows diverse approaches for different stakeholders to pursue in order to reduce greenhouse gas emission. |
