Methodology & Supporting Materials
The PACTA for Banks Methodology allows users to perform climate scenario analysis on corporate lending portfolios. It consists of three core components: physical asset-level data, financial exposures, and climate scenarios. The PACTA methodology relies on an assessment of physical assets (such as steel or power plants) linked to financial assets (such as loans, bonds, and shares) and the alignment of these assets with climate scenarios.
While 2DII can provide for scenario input and asset-level data, the methodology is a stand-alone methodology. Any climate change scenario or asset level data (ALD) set could be used to implement the methodology, provided the ALD and scenarios use the indicators on which the methodology is built.
The methodology document presented here is broken down into 3 sections:
- Section 1 explains the methodology and the underlying rationale in more detail. It describes the output metrics and discusses the required inputs. Additionally, it details the scope of the methodology. Finally, it discusses different options for allocating the macro carbon budgets (scenarios) to micro-economic actors (portfolios/clients) and for allocating the physical asset-level data to financial instruments such as loans.
- Section 2 provides the mathematical formalization behind the metrics.
- Section 3 concludes with a breakdown of the sectors, including sector overviews, the metrics used, and data inputted.
This is a publicly available, “living” methodology, meaning that we are constantly exploring ways to improve it and expand its scope.

PACTA for Banks Supporting Documents
2DII has provided a series of documents and additional resources for banks to use as part of the PACTA for Banks Toolkit:
Formatted Scenarios: 2DII has prepared a series of climate change scenarios to be used in conjunction with the PACTA for Banks Software. These scenarios range from business-as-usual to better than Paris-aligned. A document introducing climate change scenarios and detailing the methodology that 2DII has used to derive these scenarios from the raw underlying data, provided by third party scenario providers, is provided.

Steel Asset Level Emission Model: This document details the methodology behind the steel emission intensities used in the PACTA for Banks Free Data Set.
Cement Asset Level Emission Model: This document details the methodology behind the cement emission intensities used in the PACTA for Banks Free Data Set.
Disclosure and Communication Guidelines: 2DII will highlight some examples of good practice when it comes to disclosing PACTA results. In addition to this, a list of methodological parameters will be presented.
