To help engage young people in the clean energy transition and just transition for impacted communities, the EU’s Youth for a Just Transition toolkit provides a pathway for inputs from youth into execution of the Just Transition Fund. It offers principles, best practices and strategies that can help maximise the participation of youth in the programming, implementation, monitoring and evaluation of the fund. The toolkit is based on extensive literature reviews as well as interviews with experts and stakeholders, leading to 30 best practice examples for youth engagement. Actions identified include appointing youth ambassadors, structured dialogue with young people and dedicated activities at schools. As a result, the toolkit is expected to lead to better-targeted strategies and measures for implementing the just transition that incorporate the needs, opinions, fears and hopes of youth as an important part of the dialogue and decision-making process.
