Assessment of carbon reduction benefits of wind power contributes to better policy-making of energy development from a decarbonization perspective. In this study, we employed a combination of the life cycle assessment and wind power generation model to evaluate the carbon emission and power generation at the provincial and municipal levels of the whole life cycle of wind power in Xinjiang, a region abundant in wind resources and in need of wind power development for achieving decarbonization of the energy system. We also quantified the carbon reduction benefits offered by wind power when compared to thermal power and photovoltaic power. This approach effectively addressed the insufficient consideration of spatial differences in traditional life cycle assessments. The results showed that the average electricity generation of wind power in different cities of Xinjiang was 13.1×10⁷ kWh. The total carbon emission over the life cycle of wind power amounted to 3944.24 tCO₂-eq, of which 1424.79 tCO₂-eq could be reduced through material disposal and recycling. In terms of carbon reduction benefits, wind power in Xinjiang achieved an average reduction of 906.72 gCO₂-eq/kWh compared to thermal power, accounting for 97.44% of the total emissions of thermal power. The priority areas for wind power development include Hami, Bayingolin, and Beitun. Compared to photovoltaic power, the carbon reduction benefits can be as high as 43.85 gCO₂-eq/kWh (Degradation rate(DR)=1%) and 169.84 gCO₂-eq/kWh (DR=3%), respectively. In this scenario, wind power should be primarily deployed in the Kizilsu Kirgiz Autonomous Prefecture, Kashgar, and Hotan. It should be noted that there is uncertainty in assessing the emission intensity and carbon reduction benefit of wind power at a small local scale. Further evaluation is needed to obtain more refined results. In the future, there should be a strong emphasis on the development of the local wind power industry in Xinjiang, creating a green supply chain and accelerating the development of disposal and recycling technologies to enhance carbon reduction benefits.
