Grigol Nemmy, who studies in the energy systems and environments in the University of Wisconsin, said that these technologies promise and remove large volumes of CO2 – but he also noted that they have "side effects and concerns". For example, demand for land could increase the energy of biomass for agricultural purposes.
"One of the major concerns about climate change is food availability, harvest and water supply and we talk about the problem that uses water and land used for food," Nemt told the applicant. "This is the thing that society is quite sensitive and small disorders can really have a big impact."
Both carbon filming Technological processes "for their infancy," Levin said, and has potential disadvantages that need to be overcome. Energy from CO2 is required by carbon neutral, for example to avoid emissions emissions.

At the same time, at least two companies are trying to get CO2 into a firearm. Climeworks's first operator in Switzerland was joined by 2017 and aimed at 1% of the world's global emissions by 2025. The second, based in British Columbia, developed by Carbon Engineering, estimates that up to a million tons of CO2 cost competitive with other renewable energy technologies.
