1.2. Research purpose
Our purpose is threefold: (i) to provide a methodology or framework to support and evaluate corporate
environmental strategies and management approaches; (ii) to propose a methodological approach for structuring
multi-objective problems involving multi-stakeholder DM in a participatory context, searching for value co-creation
from both societal and corporate perspectives; (iii) to apply the theoretical conclusions drawn from the previous
objectives to a case study in the context of a bus public transport company. The main reasons for choosing this
context are now presented bearing in mind that integrating environmental policies into corporate sustainability is
strongly dependent on the area of intervention. Public transport companies play a quite visible role in the dimensions
of corporate social responsibility, namely because of four reasons: (i) they provide daily services crucial to mass
customers’ mobility; (ii) their investments are usually of high value and rather sensitive to technological
development; (iii) they play a crucial role in the energy sector and (iv) are strongly dependent upon macro-policies.
In this paper we concentrate ourselves in the results obtained so far for the first one of the above raised drives,
illustrated with examples from an ongoing case study in STCP (Sociedade de Transportes Colectivos do Porto).
