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.
After revision:  Our results show that negative emissions could play a large role, offsetting on the order of 2.5 GtCO2 negative emissions per year with up to 1.5 GtCO2 per year of that coming from DAC.
