A unified methodology for calculating and exchanging product-level Scope 3 data across value chains. Developed by WBCSD.
With many competing climate objectives, the S&P PACT Indices are a sophisticated solution and this paper provides further transparency on what factors are driving constituent weights relative to the parent index.

What is particularly remarkable about this fixed income S&P PACT Index is that it has had a (back-tested) annual tracking error of only 0.2% versus its underlying index; specifically, it has achieved a material benchmark-relative reduction in carbon exposure of 59.1% as of .

The PACT Methodology provides a unified approach to product carbon footprint (PCF) calculations and data exchange across industries. It emphasizes accurate, granular, and comparable data to improve carbon transparency and decision-making.
PACT Methodology Version 3 represents a significant advancement in product-level carbon calculation, enhancing accuracy and transparency by building on the feedback received from its users and the latest GHG accounting best practices.
