Aluminium Industry Achieves Significant GHG Emissions Reduction Amidst Production Growth
The aluminium industry is witnessing a remarkable transformation as it manages to grow production while simultaneously reducing its greenhouse gas (GHG) emissions. Recent findings released by the International Aluminium Institute (IAI) highlight these significant developments, showcasing an impressive 2.75% increase in global aluminium production, which reached 111.2 million tonnes in 2023. This growth is particularly noteworthy given the stable total emissions reported at approximately 1,116 million tonnes of CO2 equivalent (CO2e).
More importantly, the emissions intensity—a measure that indicates the amount of CO2e emitted per tonne of aluminium produced—has seen a substantial decline. In 2023, this figure fell by 2.33%, marking a total emissions intensity of 10.04 tonnes of CO2e per tonne. This reduction is part of a larger trend observed since 2020 when the industry peaked in emissions. To date, emissions intensity has decreased by 11.5%, emphasizing the strides taken in sustainable practices within the sector.
IAI Secretary General Miles Prosser has expressed optimism regarding these results. He noted that these figures reinforce the belief that the industry has reached a pivotal juncture, wherein the growth of aluminium production is no longer tightly linked with an increase in emissions. The data serves as an encouraging indication that initiatives implemented by IAI members are taking root, enabling enhanced production without significantly escalating greenhouse gas emissions.
Despite these positive developments, Prosser also acknowledged the considerable challenges that lie ahead. While emissions levels held steady in 2023, they underline the ongoing necessity for the industry to foster further reductions. Prosser emphasized that while existing efforts and investments in emission-reduction technologies have created a robust foundation, the journey toward significant climate goals will require accelerated action.
The aluminium sector is crucial in supporting various industries seeking to minimize their carbon footprints, particularly through its role in generating and distributing clean energy and facilitating the shift to electric vehicles. As the world increasingly turns its attention to sustainability, the demand for aluminium continues to rise. This presents both a challenge and an opportunity for the industry to step up its investments in emissions reduction initiatives across its value chain.
In its latest report, the IAI disclosed specific figures regarding production processes. The emissions intensity for primary aluminium production saw a decline from 15.1 million tonnes of CO2e per tonne in 2022 to 14.8 tonnes in 2023. This highlights significant improvements in production methods geared toward more sustainable practices.
Furthermore, IAI's data encompasses a comprehensive overview of emissions originating from various aspects of aluminium production, including bauxite mining, alumina refining, anode production, casting, and recycling, among others. It assesses both direct emissions from industrial processes and indirect emissions associated with energy consumption, highlighting the sector's environmental impacts and its journey towards emissions reduction.
As 2023 comes to a close, the aluminium industry stands at a crucial crossroad. The progress made thus far is commendable, yet it serves as a reminder of the imperative need for the industry to innovate and expand its efforts toward global sustainability. With the groundwork laid in prior years, stakeholders within the aluminium sector must now look toward broader, faster, and deeper emissions reductions to meet both regulatory demands and societal expectations for a greener future.
