Cambra de Comerç de Barcelona

The provided articles do not directly mention the Cambra de Comerç de Barcelona (Barcelona Chamber of Commerce). Therefore, a summary of its activities and relevance based on these articles is impossible. The articles discuss separate issues: a shortage of truck drivers in Spain and the appointment of Eloi Planes as the new president of the Instituto de la Empresa Familiar (IEF). While the IEF was founded in Barcelona, there's no direct link established to the Cambra de Comerç. Without further information explicitly connecting the Chamber to these events, any summary would be speculative and inaccurate. The articles highlight challenges in the transportation sector and leadership changes within a family business organization, but their connection to the Barcelona Chamber of Commerce is not apparent.
