Negative-emission technologies, such as direct air capture  of CO2, could reduce emissions up to 3 GtCO2/year by 2035, equivalent to 7% of 2019 global emissions. However, they can increase net water consumption by 35 km3 yr-1 in 2050  under the low-overshoot emissions scenario. According to other estimates, capturing 10 Gt CO2 could translate to water losses of 10-100 km3, depending on the technology deployed and climatic conditions  . Some DAC technologies that include solid sorbents also produce water as a by-product, but not in quantities that can offset total water losses  .
