1. Decarbonization of Light Vehicles in Brazil
Brazil has a successful history of using biofuels in transport. The 1973 Oil Crisis motivated the creation of the National Alcohol Program (Proalcool), establishing ethanol as an alternative to oil-derived fuels. The program contributed to reducing air pollution by replacing lead as an anti-knocking agent and reducing carbon monoxide and hydrocarbon emissions
[1]. Biofuels are considered carbon-neutral on exhaust emissions as the emitted CO
2 has been previously captured from the atmosphere by photosynthesis. However, there are greenhouse gas emissions in fuel production and transportation. The first Brazilian ethanol-powered automobile was launched in 1979.
Automotive gasoline in Brazil is a blend of 27.5% anhydrous ethanol (E27). Ethanol for vehicles (E100) contains up to 4.5% of water. Flex fuel engines can run on any mixture between E27 and E100. There are about 44 million active light vehicles in the domestic fleet and 74% of them are flex fuel
[2]. It is estimated that 70% of flex fuel vehicles run on gasoline. Ethanol consumption is influenced mainly by the ethanol to gasoline price ratio. Ethanol prices are affected by weather, government policies, international sugar prices, crude oil prices, and transport costs
[3].
Out of 1.98 million new light vehicles registered in 2021 (79% passenger cars and 21% light commercial vehicles), 84% were fitted with flex fuel engines, 3% with gasoline engines, and 13% were diesel-powered
[2]. Only 2,851 electric cars were sold in 2021, just 0.14% of light vehicle sales
[4]. In 2020, 85% of electric power in Brazil was generated from renewable sources, led by hydropower 63.8%, followed by wind generation 9.2%, biomass 9.0%, and solar energy 1.7%
[5].
The Vehicle Emissions Control Program (PROCONVE) started in 1986, and it progressively reduces new vehicle emission targets
[6]. Although it sets targets for carbon monoxide, nitrogen oxides, hydrocarbons, soot, aldehydes, and sulfur oxides, it does not establish CO
2 limits directly. New phases in 2022 and 2025 will introduce progressively more stringent limits on non-methane organic gas and nitrogen oxides, both ground level ozone forming substances
[1][7]. Although there is no current legislation explicitly mentioning vehicle electrification as a route to energy efficiency and decarbonization in Brazil
[6], the PROCONVE requirements will demand improvements in current engine technology and possibly an increase in the share of electrified vehicles
[1].
Vehicle electrification is the transition from pure internal combustion engine vehicles (ICEVs) to full battery electric vehicles (BEVs), often with intermediate stages of electric hybridization—the combination of combustion engines and electric motors
[8][9][10]. Electrification is inevitable for carbon neutrality in transport
[1][8][9][10][11]. Besides climate damage, sticking to carbon fuels would isolate a country from the global industry, which would seriously affect its competitiveness and access to technology
[8][9][12][13]. However, Brazil is not ready to shift abruptly to pure battery electric vehicles, as most of its population would be unable to afford them, and the massive investment in infrastructure is beyond its current capacity
[1][8][9][14][15].
2. Technology Evolution and Dominant Design
Green innovations are technologies and practices that improve the quality of human life and reduce the impact on the environment. They minimize the usage of energy and materials, as well as reducing pollutant emissions and waste
[16]. Incremental innovation (continuous change) occurs along an existing technology path, while radical innovation (discontinuous change) is related to the emergence of a new technology
[17]. A new technology path usually starts with an
innovation shock, a rupture from the existing technology
[18].
The emergence of a dominant design is a landmark in the transition of technology from the stage of radical innovation to incremental innovation
[19]. A dominant design is a set of product features that defines a product category and is widely adopted by the industry as a de facto standard competitors must adhere to
[16][17][20]. The phase prior to the dominant design is called the era of
ferment and is characterized by discontinuous innovation, many competitors, intense experimentation, and high growth rates
[19][21][22]. Electric cars are in the fermenting stage of industrial evolution
[17].
A dominant design marks the transition from a focus on product innovation to process innovation
[17]. Although the radical product innovation phase is over, there is an increase in incremental product variations. A key aspect of the emergence of a dominant design is the dramatic reduction in product costs
[19][21]. The increase in production volumes accelerates learning, standardization, and modularization of components
[22][23]. Prices fall and most potential consumers adopt the new product.
A systems view provides a better understanding of technology innovation and dominant designs
[16][23]. Dominant designs emerge not at the product system level but first in components or subsystems
[24]. When dominant designs in the set of central or core subsystems consolidate, a system dominant design emerges. Core components are those that affect the largest number of product characteristics or features, i.e., they have many connections
[16][23]. Peripheral components, affect few characteristics and thus have fewer connections. The larger the number of connections in a product, the higher its complexity (i.e., it has many variables)
[16].
Architecture is the way components of a system are connected and organized
[24]. A dominant design is a family of designs with common and stable core subsystems and architecture
[25]. However, dominant designs are unlikely to be present in all components (subsystems). Once the core components of a design are settled, development shifts to peripheral components. Core components become invariants that are not revisited in a new design
[24][26], reducing the design space, and restricting variations to peripheral features
[23]. A replacement of core components implies a change in the dominant design and new technology.
Adner and Kapoor
[27][28] expanded the notion of technology evolution by adding the
ecosystems dimension. Most technologies depend on complementary technologies to come to fruition, delivering value. An ecosystem is a community of multiple actors and activities aligned to create and deliver value to customers. It includes producers, suppliers, competitors, distributors, customers, and other stakeholders, and adds
complementors, such as BEV recharging infrastructure, energy utilities, battery reutilization, and recycling firms
[29].
Beyond products, competition happens among ecosystems. Substitution depends on the capacity of a new technology to overcome its challenges, and on the existing technology to keep improving
[30][31][32]. In
creative destruction, the new technology overcomes its challenges quickly and the old technology is unable to catch up, being rapidly superseded. The
illusion of resilience happens when the existing technology is unable to evolve, but it lives a bit longer because the new technology struggles to solve its challenges. However, it is a matter of time before the old technology is disrupted.
When a new technology faces significant entry barriers and the incumbent technology still has room for significant improvement, substitution tends to be slow, with robust resilience. Battery electric vehicles in emerging countries are such a case. There are considerable barriers for the dissemination of battery vehicles, and internal combustion engine vehicles can still be improved. However, if the new technology surmounts its difficulties quickly but the incumbent also improves vigorously, replacement is gradual, in a period of robust coexistence. The relation between pure internal combustion engine vehicles and hybrid vehicles is akin to that situation. The need to create a new ecosystem for battery vehicles can generate considerable tension and resistance. Hybrids may bridge the gap using existing manufacturing and fuel infrastructure.
Electric vehicle technology depends on the development of batteries with enough energy storage and power delivery, vehicle design (electric motors, control systems, architecture), on recharging infrastructure, power supply from the grid, battery reutilization, and recycling. The competition is not only between technologies but between the ecosystems supporting internal combustion vehicles (manufacturers, oil industry, biofuels industry, suppliers, dealers) and electric vehicles (manufacturers, battery makers, charging firms, power suppliers, battery reuse, and recycling firms).
Those vehicles should be affordable but practical, comfortable, and safe for small family usage, including enough driving range for holiday trips. The significant cost reduction necessary to make battery electric vehicles accessible to current automobile buyers can only be achieved with the economies of scale that follow the emergence of a dominant design
[24]. The transition to electric cars promises more efficient use of energy and materials in the automobile industry. As the industry moves from fuel intensive to materials and energy intensive
[33][34], battery reutilization and recycling—still in the early stage and with no established standards and procedures—will also be a key element in the transition.
3. Socioeconomic Barriers and Policy Pathways in Brazil's EV Transition
While Brazil’s automotive industry holds considerable potential to participate in the global shift toward electric mobility, the socioeconomic realities on the ground demand tailored solutions that go beyond technology and market trends. In a country marked by income inequality, regional development gaps, and infrastructure limitations, the path toward decarbonizing light vehicles must account for broader social and economic inclusion.
A key challenge is affordability. Although electric vehicles (EVs) promise lower operating costs over time, the high initial cost of acquisition remains a substantial barrier for most Brazilian households. According to a 2023 IBGE household income survey, a significant portion of Brazilian families earn below the national average monthly income of R$2,800 (approximately USD 540), making the purchase of an EV—most of which cost upwards of R$150,000 (USD 29,000)—an unrealistic prospect. Even with government subsidies, without the development of locally manufactured, entry-level EV models, the Brazilian market is likely to remain limited to niche consumers in upper-income brackets.
This disparity underscores the need for targeted fiscal and financial policy tools to catalyze a more inclusive EV adoption. These may include zero-interest loan programs for low-income households, tax deductions tied to household emissions reductions, and subsidies for pre-owned electric vehicles. Additionally, policies should prioritize public and shared electric mobility systems—such as electric buses, taxis, and car-sharing programs—to ensure the environmental benefits of electrification are felt across all social strata.
Another critical barrier lies in the spatial distribution of infrastructure. While EV charging infrastructure is gradually expanding in major cities such as São Paulo, Brasília, and Curitiba, vast rural and peripheral urban areas remain underserved. This limitation contributes to “range anxiety,” particularly in a country as geographically expansive and diverse as Brazil. Moreover, the lack of a unified national strategy for charging infrastructure investment and regulatory harmonization between states hampers private sector participation.
To address this, a national roadmap is needed to develop Brazil’s charging ecosystem. Public–private partnerships can play a pivotal role in deploying fast-charging stations along interstate highways, in public parking areas, and within logistics corridors. Additionally, Brazil can leverage its energy transition agenda—rooted in renewable sources like hydro, wind, and biomass—to power these stations with low-carbon electricity, thus reinforcing the environmental rationale of EVs.
An often-overlooked dimension in the EV transition is the role of education and workforce development. The shift from internal combustion engines to electric drivetrains and battery systems necessitates a radical transformation in automotive engineering, maintenance, and manufacturing skill sets. Without investing in the requalification of workers and alignment of technical education curricula with emerging EV technologies, the transition may displace workers and further entrench existing inequalities in the labor market.
The Brazilian government, through agencies such as SENAI and EMBRAPII, can foster vocational training programs in battery diagnostics, EV assembly, and power electronics, with regional emphases depending on existing industrial capabilities. Moreover, automotive clusters—such as those in São Paulo, Minas Gerais, and Paraná—can become innovation hubs by hosting EV-focused research centers in partnership with universities, startups, and global firms.
It is also important to consider the environmental externalities associated with EV adoption in the Brazilian context. The benefits of EVs in urban air quality and carbon mitigation are substantial, but the upstream environmental impacts of battery raw material extraction and manufacturing must be managed sustainably. Brazil is home to significant lithium and nickel reserves, especially in the states of Minas Gerais and Bahia. If exploited responsibly, these resources could serve both domestic EV production and export markets.
However, mining operations must be governed by strict environmental and social standards, including community consultation, biodiversity protection, and post-extraction land rehabilitation. This could be facilitated through regulatory innovation, such as the introduction of a “green mining” certification system to ensure that battery material production aligns with the broader goals of sustainable development and ESG compliance.
Recycling and second-life applications for EV batteries also represent both a challenge and an opportunity. Currently, Brazil lacks large-scale facilities for lithium-ion battery recycling, leading to potential environmental risks as EV adoption grows. Policymakers and manufacturers must collaborate to establish a circular value chain for EV batteries, incorporating end-of-life collection systems, refurbishment facilities, and advanced material recovery technologies. These processes will not only reduce waste but also decrease reliance on virgin materials, making the overall EV ecosystem more resource-efficient and resilient.
On the international front, Brazil should pursue strategic alliances to accelerate its EV transition. Bilateral cooperation with countries leading in EV technology—such as China, Germany, and South Korea—can enable technology transfer, joint ventures, and investments in local production capacity. Through MERCOSUR and other trade platforms, Brazil can advocate for common regional standards on EV safety, emissions, and charging protocols to facilitate cross-border adoption and market integration.
Finally, public perception and consumer education are critical for accelerating EV diffusion. Although environmental consciousness is growing in Brazilian society, misinformation and skepticism about EV performance, safety, and maintenance persist. Nationwide information campaigns, public demonstrations, and consumer incentives—such as free tolls or preferred parking—can serve as behavioral nudges to shift preferences toward electric mobility.
In summary, Brazil’s path toward vehicle electrification is shaped not only by technical feasibility but also by socioeconomic and institutional dynamics. A holistic transition will require synchronized action across policy, industry, infrastructure, and society. While the nation’s experience with biofuels offers a solid foundation, the next leap into electrified mobility must be underpinned by inclusive planning, regional development, and sustainability at every stage of the value chain.
