"The recent Sixth Assessment Report from the Intergovernmental Panel on Climate Change showed only narrow pathways to preventing the Earth from warming more than 1.5 degrees Celsius above preindustrial levels. [...] Indeed, even if governments worldwide collectively move to stop using fossil fuels and fully transition to clean sources of energy by midcentury, given the amount of existing GHGs already in the atmosphere, additional measures are needed to achieve negative emissions and keep the Earth within 1.5 degrees Celsius of warming. Negative emissions scenarios can only be accomplished using a combination of mitigation pathways that include 100 percent clean energy as well as methods to draw down and sequester excess carbon dioxide (CO₂) from the atmosphere—a process, known as carbon dioxide removal (CDR), that can be either nature- or technology-based."

"As a sign of ever-increasing interest in CO₂ mineral storage, Carbfix has compiled a mapping tool that shows the feasibility of applying the Carbfix technology for industries and nations to assess as a part of their climate strategy. The global storage potential is greater than the emissions of the burning of all fossil fuels on Earth.It is estimated that Europe could theoretically store at least 4,000 billion tons of CO₂ in rocks while the United States could store at least 7,500 billion tons."

"Dr. Klaus Lackner was one of the first scientists to explore how to remove excess CO2 from the atmosphere. In this wide-ranging masterclass interview, Klaus and host Dan Miller discuss the feasibility, scalability, safety, and cost of large-scale Direct Air Capture (DAC) and sequestration of atmospheric CO2. Klaus Lackner is the director of Center for Negative Carbon Emissions and a professor in the School of Sustainable Engineering and the Built Environment of the Ira A. Fulton Schools of Engineering at Arizona State University."
