The model combines legal thinking, technological management, and regulatory risk mitigation. In 2025, environmental concern funds moved more than R$60 billion in Brazil.
According to the Climate Bonds Initiative, the accumulated sustainable debt market in Brazil reached US$ 49.3 billion by the first half of 2025, establishing the country as the main market in Latin America in this segment, consolidating itself as the main protagonist of the demand for investments linked to the green agenda. In this expanding environment, where funds and investors seek legal security, solid governance, and reliable technical criteria, the Brazilian market has just gained a new methodological proposal aimed at attracting capital. The initiative arises from a doctoral thesis defended at the Institute of Energy and Environment of the University of São Paulo, the IEE-USP.
The researcher Rodrigo Brandão Fontoura, a lawyer and professor with experience at institutions such as FGV, Ibmec, and PUC-Campinas, presents in the study the ESGx model. The proposal was developed to help Brazilian companies reduce regulatory risks and align with the more rigorous demands of the global financial market.
USP thesis proposes ESGx model to strengthen governance and attract investments
According to the study, the most widespread ESG indicators in the Brazilian energy market still present significant gaps. The thesis argues that for the country to transform its environmental potential into effective capital attraction, it will be necessary to raise the technical standard of corporate sustainability evaluation and management.

More than 80 million kilometers of wires need to be replaced by 2040: the energy transition doesn’t just depend on panels and electric cars, but on a colossal race for copper, aluminum, transformers, and recycling of old cables.

In a historic decision, Aneel regulates the use of batteries in the Brazilian electrical system and lays the groundwork for large-scale energy storage, reducing waste, enhancing energy security, and attracting new billion-dollar projects.
In Fontoura’s view, Brazil is experiencing a strategic opportunity to expand its position in the green economy, but international capital tends to concentrate on companies that demonstrate consistent technical governance, robust risk management, and clear compliance criteria. It is precisely at this point that the ESGx model intends to act.
The methodology was designed to expand the traditional concept of ESG and offer a more comprehensive analysis of the business structure. The goal is to strengthen investor confidence and improve the positioning of companies that wish to issue green bonds, raise international funds, or access new fronts of sustainable financing.
ESGx model expands sustainability analysis with eight management pillars
The ESGx proposes the enhancement of the traditional ESG model through eight management pillars. In addition to the environmental, social, and governance axes, the methodology also includes the fields of economics, integrity, compliance, risk management, and innovation.
The proposal is that each sustainability demand be analyzed transversally, considering different strategic dimensions of business operations. Instead of limiting the evaluation to more generic criteria, the model suggests a broader filter, focusing on corporate governance, regulatory prevention, and adaptability to the business environment.
This approach seeks to respond to a growing market demand. To issue green bonds or raise funds directly from major global managers, companies need to demonstrate not only environmental commitment but also institutional consistency and execution capability.
Electric energy sector leads sustainable bonds and expands leadership in Brazil
The advancement of the sustainable bonds market shows how the energy sector is taking a central role in the green financing agenda. By accounting for almost half of the volume issued, the electric energy area reinforces its strategic position within the transition to a low-carbon economy.
The leadership of the electric sector also reflects the structural weight of energy distribution in the country. According to Abradee, the distributors associated with the entity serve more than 90 million customers and cover 99.6% of Brazilian consumers, which shows the strategic dimension of this segment within the national infrastructure.
This scale helps explain why the agenda of governance, regulatory predictability, and corporate sustainability has gained so much relevance in the sector. In a capital-intensive market, with a strong dependence on institutional trust and a constant need for investment, more robust management models tend to become increasingly decisive for enabling long-term fundraising.
The dominant presence of the private sector increases the importance of more sophisticated governance and sustainability models. In a critical infrastructure market, regulatory trust and institutional predictability have become decisive factors for enabling long-term investments.
Energy in Brazil attracts capital through scale, demand, and digital transformation
In Fontoura’s assessment, the private sector identifies in the energy distribution in Brazil a rare combination of market scale, demand growth, and the possibility of value capture. This scenario is further strengthened by the pressure brought by the digital economy, which requires more intelligent, decentralized, and data-driven energy systems.
This transformation expands the space for companies capable of integrating innovation, risk management, compliance, and sustainability into a single corporate strategy. In other words, the market is not only looking for green assets but also business structures capable of sustaining growth with regulatory security and operational efficiency.
As a result, the advancement of sustainable bonds and the emergence of methodologies like ESGx indicate that the debate on corporate sustainability in Brazil has entered a new phase. More than institutional discourse, the green agenda now demands technical consistency, expanded governance, and real capacity to meet the demands of global capital.
Sustainable bond market in Brazil enters a new phase of technical demand
The growth above R$ 60 billion in movement shows that the sustainable finance market in Brazil continues to advance. But the expansion of volume also increases the pressure for more solid evaluation criteria, especially in capital and regulation-intensive sectors, such as energy.
In this context, the thesis developed at IEE-USP proposes a response directly connected to current demands. By expanding the corporate sustainability analysis framework, ESGx attempts to bring Brazilian companies closer to the standards required by investors seeking predictability, integrity, and long-term security.
The result is a movement that goes beyond the issuance of bonds. What is at stake is Brazil’s ability to convert its potential in the green agenda into real investment flow, with strong governance, clear methodology, and sufficient credibility to compete for the most demanding capital in the international market.
