In pursuing a sustainable future, young people are at the forefront as essential partners in navigating transitions and shaping tomorrow. The Just Transition Mechanism is a crucial tool that ensures a fair shift towards a climate-neutral economy while leaving no one behind. Youth involvement is vital as they hold the key to the future economy. Recognizing their right to decision-making and engaging them in the transition process is imperative. The European Union has initiated the development of a toolkit for youth participation in the Just Transition Fund, which underscores the commitment to youth inclusion. This toolkit facilitates co-governance and fosters ambitious and meaningful youth participation processes in target regions. By amplifying the voices of young people, the transition can offer real revitalization and hope for communities. The toolkit is tailored to regional policymakers and stakeholders, guiding them in organizing meaningful youth participation. It draws from extensive research and direct engagement with young people, policymakers, and experts and offers practical techniques and examples to enhance youth engagement strategies. By empowering young people and fostering inclusive decision-making, the toolkit paves the way for better quality strategies and interventions, ensuring a just transition for all. In conclusion, empowering young people in the transition process is not just a matter of inclusion but a fundamental necessity for creating a sustainable and equitable future. Through meaningful participation and co-governance, young people can drive positive change, shaping a transition that benefits communities and preserves the planet for future generations.
