The Improper Use of Wood Stoves That Causes Significant Smoke Emissions Can Be Classified as Pollution, Based on the Environmental Crimes Law (Law No. 9,605/1998), and Result in Administrative or Criminal Sanctions in Specific Situations.
Brazilian environmental legislation states that causing pollution at levels that result in or may result in harm to human health or the environment constitutes an environmental crime. This provision is detailed in the 54th article of Law No. 9,605, of February 12, 1998 (Environmental Crimes Law). According to the text of the law, causing pollution of any nature that may jeopardize human health or compromise the environment is subject to penalty (detention, fines, or both), and federal legislation also allows for the application of administrative sanctions for environmental infractions, according to the regulations of Decree No. 6,514/2008.
Federal legislation does not expressly prohibit wood stoves in residences. What may constitute an environmental infraction is the excessive emission of smoke or pollutants that generates harm, discomfort, or risk to public health or the environment, which can be penalized based on general pollution control norms.
Wood Stoves and Air Pollution
Wood stoves operate through the combustion of wood or biomass, a process that generates solid particles and gases in the smoke. This type of emission is considered a source of air pollution, especially in urban areas or with close proximity to neighbors, where the smoke may invade neighboring properties.

Although the focus here is on environmental legislation, studies on wood combustion show that burning this fuel can generate high concentrations of fine particles and other pollutants in the air, which can affect local air quality.
Judicial Cases Related to the Use of Wood Stoves
In judicial decisions, there are records of situations involving wood stoves in urban areas where the impact of smoke on the health and tranquility of neighbors was recognized.
In a case judged by the Court of Justice of Minas Gerais, the smoke from the use of the wood stove was considered a cause of discomfort and aggravation of health issues, resulting in the demolition of the structure and a daily fine limited to R$ 10,000, in addition to compensation for moral damages.
In another example of jurisprudence, the continued use of a wood stove that caused ongoing discomfort to a neighbor was the subject of a legal action discussing the necessity to cease the harmful interference with health and safety.
These cases reinforce that smoke, when considered a relevant nuisance or source of health risk, can be treated as a situation subject to civil liability and potential administrative sanctions.
Fines and Environmental Sanctions
Decree No. 6,514/2008 regulates the administrative sanctions provided for in the Environmental Crimes Law and establishes that activities that cause atmospheric pollution may be subject to notice of violation and fines.
The amount of the fine depends on the applicable legislation in the specific sphere (municipal, state, or federal), the severity of the emission, and technical criteria defined by the competent environmental authorities.
In some cases of violation for pollution resulting from smoke emissions, penalties can exceed R$ 10,000, depending on the circumstances and local regulations.
Municipal Legislation and Local Restrictions
In addition to federal legislation, various municipalities have their own regulations in their codes of conduct and environmental laws that govern the use of fire and the emission of smoke in urban areas.
In many municipal codes, the emission of smoke that causes disturbance, discomfort, or risk may be treated as an administrative infraction subject to penalties, including fines.
For example, municipal laws already foresee fines for urban burnings and burning debris in residential areas.
Difference Between Owning and Using a Wood Stove
Federal environmental legislation does not classify owning a wood stove as illegal. What can lead to penalties or fines is the use that results in significant pollution emission or discomfort, especially in urban areas:
- excessive smoke emissions;
- use for burning waste, garbage, or prohibited materials;
- inadequate chimneys or uncontrolled emissions;
- pollutant emissions that affect neighbors or public areas.
In these scenarios, the environmental authority can issue a notice of violation based on pollution control norms.
Interference in Health and the Environment
The legislation addressing atmospheric pollution in Brazil is supported by the Law No. 9,605/1998, which aims to protect the environment and human health against pollution of any kind.
The Federal Constitution also establishes the protection of the environment as a collective right and duty of the public authorities and the community (Article 225), creating a constitutional basis for complementary regulations and the actions of environmental agencies.
Complaints and Enforcement
In situations where the smoke from a wood stove is considered a nuisance or a risk, municipal or state environmental agencies may receive complaints from neighbors, conduct inspections, and determine corrective measures.
If the violation is confirmed, the responsible party may receive a notice of violation and fines based on applicable environmental legislation, according to federal, state, and municipal regulations.
The use of wood stoves at home is not prohibited by federal law in Brazil simply by existing. However, when the use of this equipment results in smoke emissions at levels that cause air pollution, health risks, or significant discomfort, this may be classified as an environmental infraction based on the 54th article of Law No. 9,605/1998 and result in penalties, administrative fines, and even civil liability in related judicial decisions.
Therefore, in some areas, especially in urban locations with their own legislation or in cases of neighborhood complaints, residents using wood stoves improperly may have been fined amounts reaching R$ 10,000 or more, according to case records and applicable regulations.
