Brazil's Decarbonization Strategies Leverage Half a Century of Technological Advancements
Brazil is making significant strides in reducing carbon emissions from the transportation sector, with bioethanol playing a central role in its decarbonization efforts. The country's extensive use of bioethanol as a mainstream fuel has contributed to improving combustion efficiency and reducing the carbon footprint of vehicles.
The story of Brazil's decarbonization endeavor began in 1975 with the launch of the Proálcool program, which aimed to replace a substantial portion of petrol consumption with ethanol derived mainly from sugarcane and corn. Since then, Brazil has managed to replace over 50% of its petrol consumption with ethanol, avoiding nearly 1.4 billion tonnes of CO₂ emissions to date.
The widespread adoption of ethanol-powered cars began with the launch of flex-fuel vehicles in 2003. By 2022, these vehicles had reduced gasoline use in the transport sector by 41.7%, effectively lowering CO₂ emissions by 630 million tons, equivalent to planting 4 billion trees. Today, 97% of cars produced domestically in Brazil are flex-fuel vehicles, which can run on 100% gasoline, 100% ethanol, or any mixture of the two.
Brazil’s national biofuel program, RenovaBio, launched in 2016, complements these efforts by setting annual decarbonization targets for fuel distributors aligned with the Paris Agreement. This program uses CBIO certificates representing carbon emissions avoided by biofuel production, helping to financially incentivize ethanol producers and distributors to reduce carbon emissions in the fuel sector.
Brazil’s use of bioethanol extends beyond ground transportation. The country is testing ethanol in new sectors like marine engines for shipping to expand decarbonization beyond ground transportation. Additionally, Brazil is increasing second-generation (2G) ethanol production from sugarcane waste, boosting sustainable ethanol supply.
From an economic perspective, the use of sugarcane can also reduce Brazil's reliance on oil and improve incomes for producers. Ethanol is 20-30% cheaper than gasoline in Brazil.
The energy situation varies around the world, and Toyota, a global automotive giant, will continue an omnidirectional approach without wavering from its multi-pathway. While the company is pursuing a carbon-neutral society, it is also exploring hydrogen and options beyond battery electric vehicles (BEVs).
Toyota Times traveled halfway around the world to investigate a decarbonization endeavor 50 years in the making in Brazil. The government of Brazil initiated efforts to free its economy from dependence on imported oil in response to the 1973 oil crisis. Today, Brazil is the world's largest producer of bioethanol made from sugarcane, with production reaching 31.1 billion liters in 2022.
Julia Tauszig, UNICA's International Relations Coordinator, states that the use of sugarcane can cut exhaust emissions (CO₂) by up to 90%. The resulting ethanol from sugarcane is an environmentally friendly biofuel that doesn't increase atmospheric carbon when burned.
As the world moves towards a carbon-neutral society, Brazil serves as a benchmark and global leader in renewable transport fuels. The contribution of BEVs and other vehicles to decarbonization differs greatly depending on whether a country's electricity comes from renewable energy or fossil fuels. However, Brazil's success with bioethanol demonstrates that there are multiple paths to achieving a carbon-neutral transportation sector.

- The decarbonization story in Brazil, spanning over five decades, has its roots in the 1975 launch of the Proálcool program, an attempt to replace a significant portion of petrol consumption with ethanol derived mainly from sugarcane and corn.
- Today, Brazil's energy sector is heavily invested in environmental-science, with 97% of cars produced domestically running on ethanol or its mixture with gasoline, contributing to a reduction of over 630 million tons of CO₂ emissions in the transport sector.
- The financial sector is also involved in this decarbonization process, as the RenovaBio program uses CBIO certificates to financially incentivize ethanol producers and distributors to reduce carbon emissions in the fuel sector, aligning with the Paris Agreement's targets.
