Brazil's Electric Bus Revolution Gains Momentum Despite Infrastructure Hurdles

Brazil’s push for electric buses is gathering speed, with around 1,500 battery-powered vehicles now operating in nearly 30 cities. The shift has already cut over two million tons of greenhouse gas emissions. Yet challenges remain in scaling up the infrastructure needed to support further growth. São Paulo leads the transition, hosting most of the country’s electric bus fleet. The city benefits from both local and international funding to expand its clean transport network. Meanwhile, the Mutirão Brasil programme is preparing to add 600 more electric buses across eight cities within the next year. This effort focuses on upgrading grids and optimising depots to handle the increased demand.

The biggest hurdle lies in the logistics of powering these fleets. High upfront costs and long lead times for electrical upgrades create delays. Even a single 150-kilowatt charger in São Paulo can support anywhere from two to eight buses, depending on the depot and route requirements. Specialised tools, like the E-Bus Energy Sizing Tool, help calculate the exact power capacity needed at each location.

Since 2019, the International Council on Clean Transportation (ICCT) has supported this transition through the ZEBRA initiative. The programme provides technical assistance to 20 Brazilian municipalities, helping them plan and implement electric bus systems. Brazil’s goal is to deploy 38,000 renewable-powered buses by 2035, covering 35% of its transit fleet. Achieving this target hinges on improving depot infrastructure and charging networks. Without efficient upgrades, the expansion of electric buses could face further setbacks.
