How does the Rural Environmental Registry (CAR) work in Brazil?

The Rural Environmental Registry (CAR) is an electronic registry that gathers environmental information from rural properties and became mandatory under the Brazilian Forest Code (Law No. 12.651/2012). In simple terms, it is a self-declaratory registration of rural property, which can be used for environmental control, monitoring, planning, and regularization, constituting one of the main instruments for implementing and complying with the Forest Code. 

The Brazilian Forest Code is the main regulation governing the protection of native vegetation on rural properties. The legislation establishes rules for land use and ecosystem conservation, defining rules for Permanent Preservation Areas (APPs), Legal Reserves (RLs), and compliance with these rules can be assessed using data from the Rural Environmental Registry (CAR). 

In practice, the registration system would also make it possible to associate the origin of agricultural products — such as soybeans, beef, or coffee — with a specific rural property, allowing verification of compliance with environmental legislation. This ability to link production and territory gives the CAR a central role not only in environmental policy but also in the territorial traceability of production chains.

Despite its relevance, the CAR (Rural Environmental Registry) still faces significant structural and operational challenges. These challenges are mainly associated with the complexity of the parameters to be verified, the heterogeneity and fragmentation of databases, and institutional limitations in analytical capacity. These factors have compromised the speed of validation processes and, consequently, the effective consolidation of the environmental regularization process. After more than a decade since the implementation of the Forest Code, it is observed that a substantial portion of CAR registrations remain unvalidated or with land tenure inconsistencies, which weakens legal security and compromises credibility.

One of the main obstacles relates to the division of responsibilities among the different federative entities, which mainly results in asymmetries in implementation. At the federal level, the Union, through the Brazilian Forest Service (SFB), plays a central role in the management of the National Rural Environmental Registry System (SiCAR), responsible for unifying information at the national level. The federal government is also responsible for defining normative guidelines, procedures, and deadlines for registration and validation of registrations. Recently, there has been a movement towards centralizing management at the federal level, with the migration to the Meu Imóvel Rural platform, expanding the Union's responsibility in managing the database and validation processes, especially in states that do not have their own fully operational systems. Additionally, the federal role in integrating the CAR with land and environmental databases, including INCRA records such as the CCIR and SIGEF, is noteworthy.

At the state level, environmental agencies are responsible for analyzing and validating the information self-declared by rural producers. This process involves verifying the consistency of the data and the conformity of Permanent Preservation Areas (APPs) and Legal Reserves (RLs). Many states have developed their own systems integrated with SiCAR or directly manage registrations in the federal system, allowing for greater adherence to regional specificities. Furthermore, states frequently work in conjunction with the Public Prosecutor's Office to formalize Terms of Adjustment of Conduct (TACs), aiming at the environmental regularization of properties.

At the municipal level, city halls play a complementary role, especially in supporting rural producers and in the local coordination of environmental regularization, as foreseen in the National Environmental System (SISNAMA). Among their responsibilities, the following stand out: providing technical support to small producers in registering and updating the CAR (Rural Environmental Registry), monitoring information at the local level, and contributing to environmental regularization processes, when institutionally competent. 

The weaknesses observed in the system also stem, to a large extent, from the fragmentation between environmental, land, and tax databases, as well as the limited interoperability between systems. The absence of automated cross-referencing with official records—such as the INCRA's Land Management System (SIGEF), the Federal Revenue Service's National Rural Cadastre System (SNCR), and land registry offices—makes it difficult to verify ownership and the consistency of the declared information. 

In 2025, institutional changes impacted the federal governance of the CAR (Rural Environmental Registry) and the SICAR (Rural Environmental Registry System). The system's management was transferred to the Ministry of Management and Innovation in Public Services (MGI), in coordination with the Brazilian Forest Service (SFB), responsible for CAR implementation, and with technical support from the Social Security Technology and Information Company (Dataprev), responsible for the digital infrastructure. This organizational arrangement defined responsibilities among the involved agencies and structured the system's management at the federal level (CPI, 2025).

Following the migration of Sicar to Dataprev in 2024, the federal government prioritized improving the CAR database and its integration with other public registries, such as the National Rural Registry System (SNCR) and the Land Management System (Sigef), both managed by the National Institute for Colonization and Agrarian Reform (Incra). This integration allows for the cross-referencing of information between different databases, which helps to identify cadastral and land inconsistencies.

In 2025, the pre-filled CAR (Rural Environmental Registry) was launched, presented at COP30. This tool allows users to automatically fill in part of their registration data with information already available in public systems by entering their CPF (Brazilian individual taxpayer registration number) or CNPJ (Brazilian company taxpayer registration number), reducing manual steps and standardizing the registration process. There were also advances in coordination between the federal government and the states, with the creation of the CAR Network, a technical forum focused on information exchange and the development of joint solutions for the analysis of registrations and environmental regularization.

Despite progress, implementation remains slow. While some states have advanced in the analysis and validation of the CAR (Rural Environmental Registry), with greater use of automation and institutional capacity, others still face structural difficulties and give little priority to the policy's progress. This inequality is evident both in the speed of registration analysis and in the capacity to implement the PRA (Environmental Regularization Program). 

The technological advancements observed in some states, by themselves, do not eliminate the main bottlenecks in implementation, and this lack of verifiable land information in the CAR (Rural Environmental Registry) is becoming one of the main obstacles to the continuity of the analyses. In many cases, spatial conflicts between perimeters prevent automatic validation and require rectification by the producers. When this correction does not occur, the process tends to remain paralyzed.

This heterogeneity stems not only from differences in institutional capacity between states, but also from structural obstacles. According to a CPI report (2025), among the main obstacles are the fragility of land information, the overlapping of properties, and inconsistencies present in some of the self-declared information. In many cases, these limitations prevent the advancement of automatic validation, requiring corrections by the owners, which slows down the process and increases the number of stalled registrations.

At the same time, the registration phase for rural properties is already consolidated in all Brazilian states, although the national database continues to expand. In 2025, the number of registrations grew by 5,6%, exceeding 8 million registrations, driven by the individualization of settlement lots and the inclusion of small farmers and Traditional Peoples and Communities (PCTs) (CPI, 2025). This progress, however, does not eliminate the challenges of implementation: in many regions, the high number of registrations reflects more fragmented land structures, with a predominance of smallholdings, which hinders the management and analysis of the registrations.

A large portion of the records remain in intermediate verification stages, and the progress of the analyses still depends on the operational capacity of the states and the quality of the information declared.

Institutional factors also influence this process. Legal disputes and differences in the interpretation of environmental legislation affect the definition of criteria and the conduct of analyses, generating uncertainties in environmental regularization.

Although there has been recent progress, the implementation of the CAR (Rural Environmental Registry) is still marked by differences between states and by limitations in the quality of information and operational capacity. In this context, the effectiveness of the registry depends less on expanding the number of registrations and more on its validation and use in environmental regularization.

The Rural Environmental Registry (CAR) is consolidating itself as a relevant infrastructure for the implementation of the Forest Code and for its articulation with climate and land use agendas. However, its potential depends on the reliability of the data, the capacity for analysis, and overcoming institutional and land tenure obstacles that still limit its application.
