Before revision:  Our results show that , for China to be net-zero in 2060, it would need to deploy negative emissions technologies (NETs) at very large scales, on the order of 2.5 GtCO2 negative emissions per year with up to 1.5 GtCO2 per year of that coming from DAC. DAC, like other forms of negative emissions , such as bioenergy with carbon capture and storage and afforestation is an emerging technology that has not been demonstrated at a commercial scale . Deploying NETs at this scale will have widespread impacts on financial systems and resources availability such as water, land, and energy in China and beyond .
