Potential Pathways, Infrastructure, and Impacts
The Net-Zero America research, funded in-part by the Carbon Mitigation Initiative, quantifies distinct technological pathways, all using technologies known today, by which the United States could decarbonize its entire economy. With multiple plausible and affordable pathways available, the societal conversation can now turn from “if” to “how” and focus on the choices the nation and its myriad stakeholders wish to make to shape the energy transition.
The Net-Zero America website presents the pathways in an interactive context to enable policy makers and other stakeholders to extract specific results that are most useful to them. The site should be used in conjunction with the Net-Zero America report to fully understand the data contained herein.
This is the heart of the Carbon Mitigation Initiative’s Stabilization Wedges concept, a simple framework for understanding both the carbon emissions cuts needed to avoid dramatic climate change and the tools already available to do so.
Since the wedges concept is becoming a paradigm in the field of carbon mitigation, CMI has developed this website both as an educational resource and as an archive of resources for those who’d like to incorporate the wedges into their own presentations and workshops.
Developing countries now contribute more than half of global emissions, and this share is growing at a fast pace. But, most of the world’s emissions come disproportionately from the wealthy citizens of the world, irrespective of their nationality. We estimate that in 2008, half of the world’s emissions came from just 700 million people. These facts encapsulate the challenge of creating an agreement that assigns fair emissions targets to nations.
The paper “Sharing Global CO2 Emissions Among One Billion High Emitters” addresses this issue and provides a new framework for a global climate change treaty.
