The GreenELEMENT project will develop an innovative Green Business Leadership Key Competencies (GBLC) training programme for vocational education and training trainers to support 21st century business leaders in solving sustainability in their enterprises. It will help them develop a “green leadership mindset” and act responsibly in the market and economy, while respecting the environment and society. It will also support VET training policies and institutions in updating their training processes in the context of digitalization and to develop the knowledge, skills, and key competences of SME leaders in green business.
