Embodied carbon emissions of pumped storage hydropower infrastructure construction in China across temporal-spatial and driving factors dimensions.

ABSTRACT: To meet ambitious carbon neutrality targets, the transition to renewable energy has amplified demand for grid-scale storage, with pumped storage hydropower emerging as the dominant solution due to its technical maturity and economic viability. However, the embodied carbon emissions of pumped storage hydropower infrastructure construction remain critically underexplored. This study presents a systematic assessment of embodied carbon emissions from China's pumped storage hydropower development from 2000 to 2020, employing an environmentally extended input-output model combined with decomposition analysis. The results show that the cumulative emissions rose from 2.38 million tons (Mt) in 2000 to 23.83 Mt in 2020, with significant spatial variation. Anhui and Zhejiang had the largest embodied
