This document provides a framework for assessing the environmental impacts of research and innovation policy. It introduces impact pathways that connect public interventions in research and innovation to environmental pressures and impacts. These impact pathways are visualized using an "IA canvas" tool. The framework also discusses how to integrate environmental considerations into ex-ante and ex-post impact assessments of research and innovation policy. It provides guidance on identifying, measuring, and classifying relevant environmental pressures and impacts, including example methodologies, indicators, and data sources.
