Synergetic energy-water-carbon pathways are key issues to be tackled under carbon-neutral target and high-quality development worldwide,especially in ecologically vulnerable regions(EVRs).In this study,to explore the synergistic pathways in an EVR,a water-energy-carbon assessment(WECA)model was built,and the synergistic effects of water-energy-carbon were comprehensively and quantitatively analyzed under various scenarios of regional *** Province was chosen as the representative EVR,and Lower challenge(LEC)and Greater challenge(GER)scenarios of zerocarbon transition were set considering the technological maturity and regional energy *** results showed that there were limited effects under the zero-carbon transition of the entire region on reducing water withdrawals and improving the water *** the LEC scenario,the energy demand and CO2 emissions of Shaanxi in 2060 will decrease by 70.9%and 99.4%,respectively,whereas the water withdrawal and freshwater aquatic ecotoxicity potential(FAETP)will only decrease by 8.9%and 1.6%,*** could be attributed to the stronger demand for electricity in the energy demand sector caused by industrial transition *** GER scenario showed significant growth in water withdrawals(16.0%)and FAETP(36.0%)because of additional biomass *** promote the synergetic development of regional transition,EVRs should urgently promote zero-carbon technologies(especially solar and wind power technologies)between 2020 and 2060 and dry cooling technology for power generation before *** particular,a cautious attitude toward the biomass energy with carbon capture and storage technology in EVRs is strongly recommended.
