Smith, Pete; et al. (2015): Biophysical and economic limits to negative CO2 emissions
Smith, Pete; Davis, Steven J.; Creutzig, Felix; Fuss, Sabine; Minx, Jan; Gabrielle, Benoit et al. (2015): Biophysical and economic limits to negative CO2 emissions. In Nature Climate change. DOI: 10.1038/nclimate2870
"We quantify potential global impacts of the different NETs on various factors (such as land, greenhouse gas emissions, water, albedo, nutrients and energy) to determine the biophysical limits to, and economic costs of, their widespread application. Resource implications vary between technologies and need to be satisfactorily addressed if NETs are to have a significant role in achieving climate goals."
