“Skills for the Baltic Wood industry – European Quality in Vocational Education and Training”. The wood processing sector is one of the main economy drivers and exporting industries in the Baltics with high growth potential but it is facing a lack of workforce with skills relevant to the current industry development – digital, green and other skills and qualifications recognized internationally. During recent years the development of work-based learning (WBL) has been a priority of vocational education and training (VET) policy in the Baltic States and Europe. However, the main activities and improvements are focused on secondary level VET and there are minimal elements of WBL and quality assurance (EQAVET) in the next stages, including EQF level 5 VET. These challenges will be addressed by creating a sector skills alliance and developing a European quality VET training programme that aims to improve the skills of the labour force in the wood processing sector in the Baltic States.
Project
Community energy (CE) projects offer enhanced production of renewable energies (RE) from local sources (wind, solar, biomass, hydropower, geothermal) through active participation of local communities. Together, citizens co-finance, co-develop, and co-operate RE plants, and foster sustainable energy distribution, like local heating networks or biogas filling stations. Through active communication, transparent decision-making, and local benefit sharing CE projects have high social acceptance. Consequently, fostering CE projects is highly promising for increasing the share of RE in the BSR.
