CARRIS considers Quality and Environment as a path to continuous improvement of the organization and operation of the Company and as a contribution to social welfare. This contribution means the satisfaction of customers' requirements and the statutory and regulatory standards, using the available resources properly.
Therefore, it was implemented an Integrated Management System for Quality and Environment, in the area of urban public transport of passengers, which is governed by the general principles defined in Quality and Environmental Policy.
CARRIS has been developing, over the last few years, a thorough activity in environmental terms, that seeks not only the compliance with all legal requirements, but also to control and reduce all aspects of their business that may interact negatively with the environment.
Based on this aim, CARRIS implemented and Environmental Management System that, on April 2008, was certified by APCER - Portuguese Association of Certification, which is integrated with the Quality Management System, certified on January 2006.
Carris obtained in January 2006 (renewed in January 2009), the Quality Management System certification, granted by APCER - Portuguese Association of Certification, according to NP EN ISO 9001:2000, demonstrating the internal organization of the company and its application on their relation with customers.
