This repository holds the necessary tools and guidance for exchanging emissions data in line with RMI's Aluminum Emissions Reporting Guidance, along with licensing and sample files.
The guidance was launched for a public consultation in June of 2023--you can read the announcement here and related two-pager here.
The guidance serves as a methodological foundation for RMI's Aluminum Data Model. Designed in concert with the guidance, the Aluminum Data Model encapsulated the outputs of the guidance, represented as a Data Model Extension to the Pathfinder Data Model.
RMI's Aluminum Emissions Reporting Guidance serves as a tool for aluminum companies to report emissions in a way that drives industry-wide actions on decarbonization and accelerates the development of a differentiated market for low-carbon aluminum.
The broad intent of the implementation of this guidance is to ensure the following:
- Increase transparency of aluminum product-level emissions with a globally consistent methodology.
- Credibly recognize aluminum producers leading the market in terms of climate performance.
- Accelerate the development of essential technologies for net-zero aluminum by ensuring sufficient information is available to link demand with supply.
- Enable end users to compare climate performance across supplied aluminum products (of various specifications) to better inform procurement decisions.
- To aid end users in purchasing aluminum with credible and transparent climate data so they can demonstrate evidence of climate performancei to their customers.
There are three accounting principles for reporting aluminum sector emissions using this Aluminum Emissions Reporting Guidance:
As much as possible, emissions calculations should be based on first-hand information from various supply chain partners.
Companies shall report emissions against a fixed boundary (i.e., a consistent set of processes) to enable comparability and consistency between disclosures.
Ensure calculation and reporting decisions enable the development of a market for low-carbon products.
RMI's Aluminum Data Model enables the use of machine-readable sharing of the product level information calculated with RMI's Aluminum Emissions Reporting Guidance.
It has been designed as an extension to the Pathfinder Data Model. Extensions to the model allow for sector specific information to be added to the data model.
RMI's Aluminum Data Model is comprised of the following properties:
Emissions associated with all relevant processes from bauxite mining to final cast-house. For more information see Sec 2.2 Fixed System Boundary of RMI's Aluminum Emissions Reportings Guidance.
The ore-based or mine-to-smelter portion of aluminum production. For more information, please refer Secs 2.3 and 3.2 of RMI's Aluminum Emissions Reporting Guidance.
Final cast-house products such as slabs, billets, foundry alloys, wire rods, and other specialty products. For more information, please refer to Sec 2.3 of RMI's Aluminum Emissions Reporting Guidance.
Emissions associated with all relevant processes from bauxite mining to semi-fabrications. For more information see Sec 2.2 Fixed System Boundary of RMI's Aluminum Emissions Reportings Guidance.
