Porto Alegre faces serious environmental degradation due to high emissions from daily vehicle that create higher traffic. These vehicles emit greenhouse gases, particulate matter, and nitrogen oxides, harming both the climate and public health. Environmental NGOs and Public Health Organizations are pushing for urgent fleet electrification to reduce this impact. At the same time, aging infrastructure results in inefficient fuel use, higher maintenance costs, and further pollution pressuring the government to replace outdated buses more frequently. Financial instability also challenges the system: widespread fare evasion reduces revenue, limiting the city’s ability to invest in upgrades and service improvements. Meanwhile, public safety concerns, especially among women, reduce ridership and exclude vulnerable groups from accessible mobility. Women’s Rights Organizations and gender equality advocates highlight this barrier.

The Porto Alegre Zero-Emission, Safe & Equitable Transit (PAZET) Program is a three phased strategy to modernize the city’s outdated bus system. It begins with a technically feasible transition - blending biodiesel into existing fleets and piloting electric buses - avoiding costly full replacement. Charging infrastructure will be added in stages, aligned with bus lifecycles.
Financially, PAZET is viable through municipal funding, international climate finance, and NGO partnerships. Cost-benefit analysis and improved fare compliance, combined with a subsidized monthly pass, will enhance equity and revenue.
Socially, the program prioritizes safety through women-only sections, CCTV, and public education campaigns, with community feedback guiding design.
Environmentally, it reduces emissions immediately and moves toward a fully zero-emission electric fleet powered by renewables.
The program meets stakeholder needs: residents gain safer, cleaner transit; government meets climate targets; operators receive fleet support; and low-income riders benefit from affordable access. PAZET offers a scalable, inclusive, and sustainable mobility solution.

<aside> As a team developing this comprehensive proposal for Porto Alegre's public bus fleet transformation, we present a robust framework based on our thorough research and analysis. However, we approach its potential implementation with a strong sense of practical humility, recognizing that real-world projects of this scale involve dynamic factors and require detailed understanding.
While our feasibility assessments are detailed within the scope of this project, we understand that actual implementation would demand continuous adaptation. External elements like evolving market prices for electric buses, shifts in global clean energy policies, or unforeseen logistical challenges could influence timelines and resource allocation.
From a financial viability standpoint, our projections rely on current data and identified funding avenues. We acknowledge that securing and optimizing these diverse financial streams in practice would require agile management and potential adjustments based on economic shifts or new investment opportunities.
Ultimately, our commitment is to propose a flexible and adaptable strategy. We believe this approach, grounded in continuous learning and an understanding of real-world complexities, is essential for delivering the full environmental and social benefits to Porto Alegre.
