Brazil has been using ethanol as a fuel source for vehicles since the 1970s. The Brazilian government has been subsidizing and funding research to develop an ethanol-based fuel engine, and in 1979, they launched commercial vehicles that ran on ethanol in the national market. By 1985, over 95% of new cars on the road ran exclusively on ethanol. Brazil's long-term policy of supporting alcohol use in vehicles has been successful, and the country has continued to meet its standards for the consumption of biofuels. Today, most cars in Brazil are flex, meaning they can run on both gas and ethanol.

Brazil's ethanol fuel program
By 1985, over 95% of all new cars on the road in Brazil were running exclusively on ethanol, and the country was producing over 10 billion liters of ethanol per year to meet the demand. The success of Brazil's ethanol fuel program can be attributed to several factors, including the country's large arable land suitable for sugarcane cultivation, the development of dual-fuel engines, and the high oil prices that made ethanol a more affordable alternative.
In recent years, Brazil has continued to favor ethanol-fueled cars, with flex-fuel vehicles (FFVs) that can run on any mix of gasoline and ethanol, or even 100% ethanol, making up over 83% of the country's total car sales in 2022. The Brazilian government has also implemented tax exemptions for fuels like biodiesel and ethanol to encourage their use over gasoline. However, this preference for ethanol-fueled cars has hindered the uptake of electric vehicles in the country, with pure electric vehicles accounting for only 0.4% of total car sales in 2022.

Flex-fuel vehicles
Brazil's fleet of flexible-fuel vehicles is the largest in the world. Since 2003, over 30.5 million flex-fuel cars and light-duty trucks have been registered in the country, alongside over 6 million flex-fuel motorcycles. As of 2017, flex-fuel autos and light commercial trucks represented 88.6% of all light-duty vehicle registrations.
The development of flex-fuel vehicles was a response to the 1973 oil crisis, when OPEC increased oil prices tenfold. The Brazilian government began mandating the use of ethanol blends with gasoline, and neat ethanol-powered cars (E100) were launched to the market in 1979. By 1985, over 95% of new cars ran on ethanol. However, ethanol production and sales of ethanol-only cars decreased in the late 1980s due to sharply falling gasoline prices and a shortage of ethanol fuel supply.
The first commercial flexible-fuel vehicle, the Gol 1.6 Total Flex, was launched by Volkswagen in March 2003. By 2010, manufacturers that build flexible fuel vehicles included Chevrolet, Fiat, Ford, Peugeot, Renault, Honda, Mitsubishi, Toyota, Citroën, Nissan, and Kia Motors. By 2013, flex vehicles from multiple manufacturers had become a commercial success, dominating the passenger vehicle market with a 94% market share of all new cars and light vehicles sold.

Electric vehicles
Brazil is witnessing a revolution in sustainable mobility, with a significant increase in the use of electric vehicles (EVs). The country registered approximately 177,000 electric vehicles in 2024, a substantial jump from the 41,000 units recorded in 2019. This surge reflects a notable shift in consumer mindset, indicating a greater acceptance of sustainable technology.
The Brazilian market for electric vehicles is experiencing rapid growth and development, driven by several factors. One key factor is customer preference. Consumers in Brazil are increasingly opting for electric vehicles due to their environmental benefits and cost savings. Electric vehicles are recognised as a more sustainable and eco-friendly alternative to traditional gasoline-powered cars. They produce zero tailpipe emissions, which can significantly reduce air pollution in cities. Additionally, electric vehicles offer lower operating costs, including reduced fuel and maintenance expenses, making them a cost-effective choice for Brazilian consumers.
Another factor contributing to the growth of the electric vehicle market in Brazil is the increasing availability and variety of electric vehicle models. More automakers are introducing electric models to the Brazilian market, providing consumers with a broader range of options. This increased competition among automakers is leading to more affordable electric vehicle prices, making them more accessible to a wider range of buyers.
Furthermore, the development of charging infrastructure is crucial to the success of electric vehicles. Brazil currently has around 12,100 charging stations, a significant increase from the 735 stations available five years ago. The country is committed to expanding this infrastructure further, with projections indicating that the number of charging stations could reach 30,000 in 2029 and 60,000 in 2034. This expansion addresses concerns about range anxiety and accessibility, making electric vehicles a more viable option for longer-distance travel.
Brazil's unique circumstances, including its abundant renewable energy resources and strong automotive industry, also play a role in the growth of the electric vehicle market. The country's significant hydropower generation provides a clean and sustainable source of electricity to power electric vehicles, making them even more attractive to environmentally conscious consumers. Additionally, government support and incentives, along with a growing focus on sustainability, are driving the adoption of electric vehicles in Brazil.

Environmental effects
Brazil's use of ethanol as a fuel source for vehicles has had several environmental effects. On the positive side, the use of ethanol has improved Brazil's air quality. Sugarcane ethanol, the most common type of bioethanol in Brazil, has been found to reduce greenhouse gas emissions by 61% under the EPA's Renewable Fuels Standard 2 and by 71% under the European Union's Renewable Energy Directive. By 2020, over 80% of the Brazilian automobile fleet was expected to be capable of running on pure ethanol, further displacing gasoline usage.
However, there have also been negative environmental consequences. The production of ethanol in Brazil has been found to damage water quality, ecosystems, and certain communities. The cultivation of sugarcane, from which ethanol is produced, requires a lot of water, which can be a problem in countries with water scarcity. Additionally, Brazil's biofuel mandates do not include environmental sustainability criteria, and greenhouse gas emission reduction levels are not considered. This has led to concerns about the environmental impact of the increased demand for ethanol, with over 10 billion liters of ethanol being produced annually by 1985 to meet the growing demand.
The success of ethanol-fueled cars in Brazil has also had an impact on the adoption of electric vehicles (EVs). In 2022, sales of flex-fuel vehicles (FFVs) that run on ethanol or gasoline continued to surpass EV sales, with FFVs claiming over 83% of Brazil's total car sales. This trend may hinder the country's uptake of battery-operated cars in the long term.
Overall, while the use of ethanol as a fuel source in Brazil has led to improvements in air quality and reductions in greenhouse gas emissions, there are also concerns about its environmental sustainability and the potential impact on the adoption of alternative fuel sources, such as electric vehicles.

Government incentives
Brazil's government has played a significant role in the country's transition to ethanol-fuelled cars. The nation's ethanol fuel program was initiated in 1976, serving as a response to the 1970s oil crisis, during which OPEC increased oil prices by 10x. At the time, Brazil couldn't afford to import oil nor live without it, so the government began investing heavily in ethanol technology. The National Alcohol Program (PROÀLCOOL) was created by a presidential decree in 1975, and by 1979, Brazil introduced cars that could run on 100% ethanol or blends of ethanol and gasoline.
The government also subsidised and funded research to develop a domestically fuelled ethanol engine, which resulted in the launch of commercial vehicles in the national market in 1979. This early support for ethanol as a fuel source laid the foundation for Brazil's future adoption of flex-fuel vehicles.
Brazil's long-term policy of supporting alcohol use in vehicles, even during years of low oil prices, has paid off in recent times with relatively high oil prices. By 2006, about 80% of car sales were flex-fuel, and by 2022, flex-fuel vehicles made up over 83% of Brazil's total car sales.
In 2023, the Brazilian government further incentivised the use of alternative fuels by extending a federal tax exemption for biodiesel and ethanol for one year, while also offering a gasoline and ethanol tax exemption for two months. These exemptions were initially passed by the former Bolsonaro government to gain popularity ahead of the 2022 general election.
Brazil's success in integrating ethanol into its energy infrastructure serves as a reminder to other nations that rapid energy transitions are possible.
