1.5 Degrees Scenario: A Model To Drive Emissions Reduction

IAI models 1.5-degree decarbonisation scenario in a bid to drive greater emissions reductions

This scenario will guide and inform what industry does – much is currently happening.

The International Aluminium Institute (IAI) has modelled a 1.5 Degree Scenario to guide its member’s efforts to meet global climate goals. The modelling is based on IEA’s Net-Zero by 2050 scenario, combined with the IAI’s material flow analysis and future demand scenarios.

This scenario is the most ambitious decarbonisation approach and complements existing work which includes: detailed historical emissions, business as usual scenario (BAU) to 2050 and a ‘Beyond 2 Degrees Scenario (B2DS).

Both the 1.5 Degree Scenario and B2DS are consistent with the Paris agreement.

A chart titled "Greenhouse Gas Intensity Per Tonne" compares historical (2018) and projected (2050 BAU, 2050 B2DS, 2050 1.5DS) carbon emissions for primary aluminum production. This model shows emissions falling from 16.1 to 15.8, 2.5, and 0.5 tCO2e
