The urgent need for a fair and prosperous society, with a resource-efficient economy, calls for a readaptation of our lifestyles, based on learning solutions able to respond to different learning needs. Among others, micro-credentials have recently emerged as a successful approach for professional upskilling through targeted, flexible, inclusive learning paths. Inspired by the good practice of NE(W)AVE project , GREENLAB partnership (11 partners from 6 EU countries, representing the fields of VET and employment), will apply the micro-credential approach to the design of specialised VET learning resources in sustainability management and environmental consulting. Partners will initially identify those common transversal and sector-specific skills needed to succeed in line with the green transition, actively involving the target groups (i.e. business managers, project managers, business consultants, VET providers, policymakers) to ensure that the resources developed respond to their real needs. This analysis will guide the co-creation of a cutting-edge Open Online VET Course, based on micro-credentials, which will be tested with 200 representatives of GREENLAB professional fields across 5 countries and will be complemented by an impact study leading to its finalisation. VET professionals too will benefit from the creation of innovative resources enriching their learning offer and from the organisation of international opportunities for knowledge exchange, enhancing their understanding of the micro-credential approach. Moreover, several encounters with policymakers will increase their awareness of current VET and business needs, and their willingness to intervene for the green transition. Regular promotion will ensure an international transfer of innovation, involving 350 key stakeholders in final events, thus contributing to the long-term exploitation of project results and to GREENLAB’s core aim to shape more sustainable mindsets.
