Metro Ligero Oeste (MLO) is a public transport operator
committed to providing safe, efficient, high-quality mobility,
contributing to people’s well-being and the sustainable
development of the municipalities it serves.
Sustainability is an essential part of our management and
guides our decisions. We work to minimize the environmental
impact of our activity, optimizing resource use, encouraging
energy efficiency and promoting collective mobility that reduces
emissions and improves the quality of the urban environment.
Our commitment also extends to the social and economic
spheres. We maintain a constant dialogue with our stakeholders
to generate shared value, drive responsible growth and ensure
transparent, ethical management with a long-term outlook.




We have a solid Code of Ethics that covers our values, principles and conduct guidelines. It governs the behaviour of everyone at MLO when carrying out their professional activity, as well as in their relationship with our various stakeholders. This code is a core element of our corporate culture and reinforces our commitment to regulatory compliance.
It also reflects our commitment to responsible business
conduct and respect for human rights. The Protocol
on Prevention and Action in Situations of Harassment,
derived from the Equality Plan signed in December
2023, has been revised in order to strengthen its scope
and ensure more specific handling. As a result of this
revision, it has been put together as a standalone
document, approved on 21 January 2025.
In line with these principles, there were no complaints
related to our activities or administrative, economic
or judicial sanctions of any kind registered during this
period.
Regarding the relationship with stakeholders, our
commitment to the local community has been reinforced.
A new commitment was included, aimed at contributing
to quality-of-life improvement not only for our users,
but also for the community, through the promotion
of educational and social initiatives, fomenting local
employment and boosting sustainable mobility.
At MLO we have an Integrated Management System that groups various regulations and certification standards, providing a structured framework to comply with our strategic plan and promote efficiency, transparency and accountability:
Regulatory compliance is a fundamental principle for MLO, and is part of our Integrated Management System. This allows us to guarantee compliance with all legal requirements applicable to our activity, but also with the voluntary commitments we have undertaken.
Our Integrated Management System is characterized by procedures designed to identify risks and opportunities. Its main objective is to
minimize, and, where possible, eradicate the negative impacts of our operations. At the same time, it seeks to promote and maximize the
positive impacts in the different areas of our business activity.
This proactive approach contributes to strengthening the organisation’s resilience and increasing its positive contribution to the business and
social environment.
Among the procedures for requesting advice and raising concerns, we
have communication channels with our stakeholders that function as
complaint and claim mechanisms, as well as channels for receiving
suggestions and concerns.
These communication channels play a fundamental role in providing our
stakeholders with a direct and completely confidential way to express
their concerns, offer comments, ask questions or raise any matter they
deem relevant.
