 This study uses an integrated assessment model to evaluate the impact of land policies and technology subsidies on greenhouse gas emissions, air pollution exposure, and energy access in eastern Africa under different socioeconomic scenarios. The analysis shows that land policies focused on increasing sustainable biomass output can reduce GHG emissions by 10%, but delay progress towards health and energy access goals. An optimized portfolio of technology subsidies, including biogas, liquefied petroleum gas, ethanol, and PV technologies, can yield another 10% GHG savings, decrease air pollution-related mortality by 20%, and improve energy access by up to 15%. After 2030, the effectiveness of both policies decreases and depends on the overall development path of the region. The study suggests that integrated policy analysis is needed to simultaneously achieve progress in multiple sustainable development goals.
