This report describes the approach of an in-project training methodology and its plan for the RE4GREEN project to develop gender-specific capacities and skills of RE4GREEN consortium partners and their staff for use in the various tasks during the project. Firstly, RE4GREEN’s gender-responsive methodology is presented. Following this, the findings from an internal survey, aiming to identify the capacity-building needs of consortium partners, are detailed. In addition, this section will elaborate on how these findings will shape the development of RE4GREEN's comprehensive framework for research and innovation (R&I) to address environmental and climate ethics and integrity challenges. Subsequently, the planned outputs intended to bolster the consortium's capacity to conduct gender-responsive and inclusive research, including training sessions, a checklist, a gender glossary, and factsheets, are outlined. Whilst this report frames RE4GREEN’s bold stance, which centres gender considerations in the promotion of a just and inclusive Green Transition, the methodology and plan presented herein may offer a blueprint for similar projects.
