"There are several so-called negative emissions technologies that could remove carbon dioxide from the air, including those aimed at removing CO2 by enhancing natural forest and wetland uptake, using bio-energy in power production and scrubbing CO2 efficiently from air."

"To make negative emission technologies viable, industry needs physical and measurable proof of those which will be most effective and then the means to implement them at full scale. That means large government and private investments in research and development for these technologies."

"Any concerns over costs, though, should be compared to cost of doing nothing."
