Consequence tree
Definition
The consequence tree is a systematic analytical tool used to identify and structure the diverse second-order and higher-order environmental effects resulting from the deployment of an ICT solution. It acts as a comprehensive map, helping practitioners distinguish between first, second, and higher-order effects to ensure that all relevant impacts on greenhouse gas emissions are identified and categorized before quantification.
Key Characteristics
- Hierarchical Visualization: Structurally separates effects into orders (first, second, and higher-order) to track causality.
- Comprehensive Scope: Facilitates the identification of both direct and indirect (collateral) environmental consequences.
- Analytical Foundation: Provides a prerequisite mapping stage for rigorous GHG emission quantification.
- Systematic Identification: Ensures that subtle or delayed impacts are not overlooked during the assessment of ICT solutions.
Applications
- Supporting the assessment phase within a Consequential LCA.
- Assisting in the mapping of digital-enabled sustainability pathways for Greening by Digital initiatives.
- Providing a structured approach to identifying rebound effects and indirect impacts in ITU-T L.1480 assessments.

- “The consequence tree provides an analytical basis for identifying the effects induced as consequence of the deployment and use of the ICT solution, and delivers a set of collateral effects (consequences) connected to the solution in addition to its main second order effect.” — ITU-T L.1480 (Greening by Digital)
