AREA welcomes the launch of the European Year of Skills 2023

May 12, 2023

To achieve the EU’s decarbonisation goals and deployment of clean, low-carbon and efficient heating and cooling technologies, a skilled workforce with the proper training and certification is of utmost importance. All current upskilling and reskilling opportunities require not only additional promotion and funding, but also backing by additional training tools and programmes and stakeholder partnerships. Furthermore, we need to ensure that the training and certification are mutually accepted in the EU countries, which in turn should also ensure a reciprocal process of recognising such coming from overseas.
