The project was born from the partners’ desire to respond to current challenges related to integrating young people into a green and sustainable economy. The initiative aimed to create a favourable framework for developing the skills needed for employment and launching businesses in sustainable sectors, while also encouraging responsible entrepreneurship. The training aimed to prepare youth workers and youth leaders to support young people’s transition towards the green labour market and sustainable entrepreneurship. They acquired the competences, knowledge and skills needed to pass on relevant know-how to young people, participating in business plan workshops, in sessions on developing green skills facilitated by national groups, and contributing to the creation of the “Green Start-up Business Plan Model” tool for youth-led enterprises. Specific objectives achieved: SO1 – The 21 youth workers and youth leaders from 7 organisations improved their skills and adopted green best practices needed to support young people’s integration into the green labour market, through a 7-day training programme with diverse activities (green skills workshops by national groups, visits to entrepreneurs, business plan workshops, presentations on green jobs and business opportunities in each country, etc.). Link SO2 – The 21 youth workers were informed about available funding sources for young people wishing to launch a green start-up, so they could share these opportunities with their beneficiaries. SO3 – The participants’ entrepreneurial spirit was stimulated by emphasising the essential role of sustainability, innovation and creativity. SO4 – We promoted the concept of the green economy among young people, both as an employment opportunity and as an entrepreneurial option, by developing and promoting the tool, implementing the business incubator, and delivering workshops by youth workers in each country. SO5 – The 21 youth workers presented green practices and successful eco start-ups from their countries, e.g., Vcelobal, Tierra Verde and Ponio from Slovakia, Agrow Analytics and Ubora Solar from Spain, Miret sneakers and plodovi.hr from Croatia. National workshops: The Greek team created a multiple-choice quiz covering key facts and concepts related to green jobs, sustainability and renewable energy, with questions on topics such as Greece’s energy mix, circular economy, greenwashing, ESG in finance, and carbon footprint. The Slovak team presented the concept of green start-ups from their country, offering inspirational examples and raising awareness on environmentally oriented entrepreneurship. The two Spanish teams presented green start-up concepts from their country and city, offering inspirational examples and promoting environmental entrepreneurship. One Spanish team facilitated a “World Café” activity where participants explored six key sustainability themes – renewable energy, energy efficiency, sustainable urban development, sustainable mobility, zero waste, and circular economy. The Croatian team introduced participants to the 4Rs of sustainability – Reduce, Reuse, Recycle, Return – and challenged them to design green start-up ideas integrating at least two of these principles. The Latvian team presented the concept of green start-ups from their country, with inspirational examples promoting environmental entrepreneurship. SO6 – The 21 youth leaders and youth workers disseminated the competences gained during the training through the business incubator created for 30 local young people, helping them develop 4 eco start-up ideas: a café-shelter providing leftover food to homeless people, a “petting zoo” farm for rescued animals, a café powered by green energy and using only reusable equipment, and the first silkworm farm in Transylvania. They also used/will use the tool and knowledge from workshops to facilitate the transition of young people in their communities to the green labour market and eco-entrepreneurship, as well as to train other youth workers who will multiply the results. SO7 – The Erasmus+ Programme was promoted through training activities, the created tool, the business incubator, social and mass media materials, and through follow-up events already organised or to be organised by participants.
