[Ferro-Alloys.com]The International Aluminium Institute has recently published the most comprehensive greenhouse gas emissions reductions pathways available to the aluminum sector over the next three decades. The pathways are based on the IAI’s unrivalled data and leading analysis of the global aluminum industry. The new report, Aluminium Sector Greenhouse Gas Pathways to 2050, sets out three credible and realistic approaches to emissions reductions for the aluminum industry, in line with the International Energy Agency’s Beyond 2 Degree Scenario. While the industry works to reduce its emissions by about 80 %, demand for aluminum products is also predicted to grow. Over the coming decades, global demand for primary aluminum will increase by up to 40 % and recycled aluminum from post-consumer scrap will more than triple through to 2050, as economies grow, urbanize, and build up their infrastructure.

The pathways are:
 
1. Electricity decarbonisation - More than sixty percent of the aluminum sector’s 1.1 billion tonnes of CO2e emissions (2018) are from the production of electricity consumed during the smelting process. Decarbonised power generation and the deployment of carbon capture utilisation and storage (CCUS) offer the most significant opportunity to reduce emissions to near zero by 2050.
 
2. Direct emissions - Emissions from fuel combustion make up 15 % of the industry's emissions. Here, electrification, fuel switching to green hydrogen and CCUS offer the most credible pathways. Process emissions make up a further 15 % and require new technologies, such as inert anodes. These emissions and those in transport and raw materials will need to be reduced by 50-60 % from a Business as Usual (BAU) baseline scenario by 2050.
 
3. Recycling and resource efficiency - Increasing collection rates to near 100 % as well as other resource efficiency progress by 2050 would reduce the need for primary aluminum by 20 % compared to BAU, which in turn will cut the sector's emissions by an additional 300 million tonnes of CO2e per year - a figure second in magnitude only to the first pathway, electricity decarbonisation.
 
Aluminum is vital to our society. Our homes, workplaces, vehicles, digital devices, packaging, buildings that provide shelter and security – to name just a few examples – rely heavily on aluminum. Aluminum is also integral to global emissions reduction efforts, with solar panels, wind turbines and electric vehicles all depending on it.
 
The International Aluminium Institute has the most comprehensive global data on aluminum with more than 40 years of analysis on production, consumption, energy use and environmental impact.
