Alsa, the mobility company operating a large city and metropolitan bus fleet in Spain, reports that 28% of its buses are ecological or zero-emission in its latest sustainability review published this year to mark a significant milestone in the country’s history. This figure reflects the ongoing commitment to greener urban transport across its network.
Among the 2,072 total vehicles in service, Alsa deploys Class I and II buses across 44 urban and metropolitan routes in Spain. The fleet includes electric propulsion, hybrid, CNG/LNG, hydrogen, and dual-fuel options, all contributing to cleaner mobility. These green technologies account for 27.9% of the total vehicles, and their deployment helped avoid about 19,639 tons of CO2 emissions in the most recent year reported.
The company has clear decarbonisation targets, including the rollout of 100% electric autonomous buses in Spain, starting with operations in Madrid and Asturias. Other milestones include the commissioning of the first hydrogen bus to serve the urban Torrejón de Ardoz line in Madrid, and the introduction of an electric bus for intercity service. These initiatives illustrate Alsa’s strategic push toward zero-emission public transport across different service segments.
Francisco Iglesias, Alsa’s chief executive, emphasizes that the company’s decarbonisation efforts align with the United Nations Sustainable Development Goals, particularly Climate Action and Sustainable Cities and Communities. He notes a steadfast pledge that all buses will be zero-emission by 2035, reflecting a long-term roadmap for cleaner mobility.
In addition to its fleet modernization, Alsa presents a comprehensive ESG approach verified by Aenor under GRI standards. The sustainability report provides transparent details on environmental, social, and governance practices across its operations in Spain, Morocco, Switzerland, and Portugal, underscoring the company’s accountability to stakeholders and communities it serves.
Looking ahead, Alsa plans three major international contracts within the current year. These include metropolitan services in Porto, expansion of urban services by electric buses for TPG in Geneva, and the expansion of intercity services in Saudi Arabia. These international ventures demonstrate the company’s ambition to apply its green mobility model beyond national borders while maintaining rigorous ESG commitments.
On the diversification front, Alsa formed a new entity following its entry into the medical transport sector last year. This new venture, DESIR, will begin managing the recently signed emergency medical transport contract for the Community of Madrid, broadening the scope of essential mobility services while integrating ESG best practices into a broader transportation portfolio.
