Reducing Aluminium Industry Emissions Intensity and Growth

Aluminium Industry Achieves Remarkable Emissions Reduction

The aluminium industry has made significant strides in reducing its greenhouse gas emissions intensity while boosting production levels. Recent data indicates that the emissions intensity decreased by 2.33%, bringing it down to 10.04 tonnes of CO2 equivalent (CO2e) per tonne of aluminium produced. This is a commendable accomplishment, particularly as global demand for aluminium continues to rise in various sectors, including clean energy and electric vehicles.

Continuous Production Growth with Stable Emissions

In 2023, global aluminium production saw an uptick of 2.75%, reaching a remarkable 111.2 million tonnes. Interestingly, total emissions have remained approximately stable at around 1,116 million tonnes of CO2e, underscoring the industry's effort to grow while maintaining emission levels. This is the third consecutive year where production has increased without a corresponding rise in emissions, a clear indication of the industry’s commitment to sustainability.

The Importance of Emissions Intensity Reduction

The concept of 'emissions intensity’ refers to the amount of greenhouse gases produced per tonne of aluminium. In recent years, this figure has shown notable improvement; since 2020, emissions intensity has plummeted by 11.5%. This reduction is not only a benchmark for the industry but also a significant step toward achieving long-term environmental goals.

Initiatives Driving Change in the Aluminium Sector

According to experts, the initiatives adopted by key industry players, particularly through organizations like the International Aluminium Institute (IAI), are pivotal in this transformation. Miles Prosser, the Secretary General of IAI, stated that the data represents a turning point. The industry has effectively decoupled metal production growth from emissions growth, which suggests that innovative practices are being implemented successfully.

Continued Challenges Ahead

Despite the achievements, the figures from 2023 also highlight that there remain considerable challenges ahead. While emissions levels have remained steady, the industry recognizes the urgency to reduce emissions more significantly. Investments in emissions-reduction projects are essential for advancing the sector. Prosser emphasized the need for deeper and broader reductions as the demand for aluminium grows.

Aluminium’s Role in a Sustainable Future

Aluminium plays a critical role as a sustainable material across various applications, especially in generating and distributing clean energy, transitioning to electric vehicles, and promoting eco-friendly packaging solutions. With a rising demand for aluminium, manufacturers are making substantial investments to lower greenhouse gas emissions throughout the production value chain.

The Emissions Intensity of Primary Aluminium Production

Delving deeper into the emissions intensity specifics, primary aluminium production saw a reduction from 15.1 tonnes of CO2e per tonne in 2022 down to 14.8 tonnes in 2023. This continuous decrease reflects the sector’s commitment to minimizing environmental impact while meeting increasing global needs.

Insights and Statistical Overview

The IAI provides thorough insights into greenhouse gas emissions from various aspects of the aluminium production process. This includes emissions data encompassing:

• Bauxite mining
• Alumina refining
• Primary aluminium production
• Anode production
• Casting
• Aluminium recycling
• Semis production
