Described herein are embodiments related to systems, methods, and processes for sharing sustainability-related attributes and data across multiple domains. More specifically, some embodiments describe a sustainability aggregation device which may include a controller or other processor, and a memory. The memory includes a sustainability aggregation logic that can receive telemetry data associated with a first network domain, and in response, generate a multi-layer topology graph for the first network domain. In response to the graph being generated, it can be augmented with one or more sustainability-related attributes. However, the device can prune the augmented multi-layer topology graph based on one or more export policies and export the pruned augmented multi-layer topology graph to a second network domain. The multi-layer topology graph may also be utilized within a closed-loop system to monitor various aspects of the network domain and adjust one or more configurations as needed based on the received data.
