This paper reviews ALBA’s environmental practice development between 2019 and 2023. It analyzes how environmental practices have assisted Bahrain’s aluminum industry in decarbonizing. ALBA is a major aluminum maker and pillar of Bahrain’s economy, and it is a key influence shaping the country’s sustainability trajectory. The environmental trend analysis from a longitudinal lens, utilizing greenhouse gas emissions, energy, water, wastes, and afforestation as prominent environmental indicators, reveals sustained environmental performance improvement by ALBA. The environmental indicators document a decrease in GHG intensity, a boost in energy efficiency, and an increment in recycling of wastes in the span. The paper concludes that drivers of all those improvements are technological advancements, regulatory progress, as well as internal efforts. While ALBA’s remarkable record shows promise, the paper makes known continuities in challenges relating to water reuse, emissions technologies, and third-party verification. The paper makes recommendations on how ALBA’s environmental footprint can be enhanced and is educative for policymakers as well as industrial stakeholders in the GCC.
