Abstract Existing studies indicate that future global carbon dioxide (CO 2 ) removal (CDR) efforts could largely be concentrated in Asia. However, there is limited understanding of how individual Asian countries and regions will respond to varying uncertain scales CDR concerning their energy-land-water system. We address this gap by modeling various levels CDR-reliant pathways under climate change ambitions find high reliance leads residual fossil fuel industry emissions about 8 Gigatonnes CO yr −1 (GtCO 2050, compared less than 1 GtCO moderate-to-low reliance. Moreover, expectations multi-gigatonne delay the achievement domestic net zero for several regions, lead higher land allocation fertilizer demand bioenergy crop cultivation. Here, we show should prioritize emission reduction strategies while capitalizing on advantages when it most viable.
