The chemical industry is a key driver of economic growth and innovation but remains one the largest contributors to greenhouse gas (GHG) emissions. Achieving sustainability demands advancements in green chemistry cleaner production methods. This study investigates emission reduction strategies across Scope 1, 2, 3 by applying both top-down bottom-up approaches within four system boundaries. Austrian sector, with focus on ammonia, methanol, olefins, serves as case study. Results highlight potential abatement technologies alternative feedstocks—such low-carbon hydrogen methanol—to significantly reduce Hydrogen-based for ammonia along methanol olefin production, could 1 2 emissions approximately 80% compared conventional However, remain challenging due embedded carbon feedstocks CO2 use particularly product end-of-life phases. A comprehensive life cycle assessment crucial addressing these impacts. To evaluate emissions, this explores three decarbonization scenarios: reference scenario—relies fossil-based high emissions; geogenic scenario—integrates feedstock, reducing about 46%; bio-based scenario—combines biogenic achieving an total at national level. findings emphasize need system-wide approach that integrates solutions circular economy achieve climate neutrality. uncertainties policy, bio-resource availability, data gaps must be addressed ensure effective alignment goals.
