Federal Immission Control Act (BImSchG): Legal Foundations, Regulations, and Significance
Concept and Purpose of the Federal Immission Control Act
Das Federal Immission Control Act (BImSchG) is the central German law for protection against harmful environmental impacts caused by emissions. It came into force on March 15, 1974, as Article 1 of the Act on Combating Environmental Pollution and has since formed the legal foundation for immission control in Germany. The BImSchG regulates how to handle air pollution, noise, vibrations, light, heat, radiation, and similar environmental impacts in order to protect humans, animals, plants, soil, water, atmosphere, and property.
Scope and Applicability
The Federal Immission Control Act applies nationwide and has been specified by a series of regulations and administrative provisions (in particular the BImSchV regulations). It especially concerns businesses, facilities, and activities whose operation is associated with potentially harmful environmental impacts. Primarily, the law is aimed at operators of facilities requiring approval within the meaning of § 4 BImSchG, but so-called non-licensable facilities and mobile sources also fall within its scope to some extent.
Fundamental Principles and Objectives
The core goal of the Federal Immission Control Act is prevention and protection against harmful environmental impacts. Its aim is to safeguard both human health and the environment as a whole from significant disadvantages and to prevent such impacts as early as possible. In addition to the protection concept, the law also follows precautionary aspects regarding the avoidance and minimization of emissions.
Key Areas of Regulation
Protection against harmful environmental impacts (§ 1 BImSchG)
According to § 1 BImSchG, the law aims to protect humans, animals, plants, and property against harmful environmental impacts and to prevent such risks from arising. The basis is the precautionary principle and consideration of the state of the art.
Facilities Requiring Approval (§§ 4 to 21 BImSchG)
A major focus is on the permitting law for facilities that are particularly relevant to the environment due to their nature or operation. Facilities requiring approval are specified in detail in the 4th BImSchV (Regulation on Facilities Requiring Approval). When granting a permit, the authority examines whether the construction and operation of the facility comply with the requirements of the law and the associated regulations and provisions.
Approval Procedure
The approval procedure (§§ 10 ff. BImSchG) is regulated in detail and includes, among other things, rights of public participation, environmental impact assessment, and requirements for applicants. For certain types of facilities, an immission control permit is mandatory and is subject to various ancillary provisions.
Monitoring and Operator Obligations (§§ 52 ff. BImSchG)
Operators of facilities requiring approval are subject to extensive monitoring, inspection, and reporting duties. This includes regular self-monitoring, compliance with limit values, measurement and reporting obligations, as well as tolerance of on-site official monitoring measures.
Regulation Authorizations and Limit Values
The BImSchG authorizes the federal government to set technical and organizational requirements and limit values for various emissions by regulation. Relevant regulations include, among others, the 22nd BImSchV (Regulation on Immission Values for Air Pollutants), TA Luft (Technical Instructions on Air Quality Control), or TA Lärm (Technical Instructions on Noise Protection).
Emission Limitation and State of the Art
According to the state of the art, emissions must be limited (§ 5 BImSchG). What constitutes the “state of the art” is derived from expert reports, technical rules, and experience. As a rule, the current technical possibilities for limiting emissions must be implemented without exception.
Public and Private Rights
Participation and Rights to Legal Action
Within the framework of approval procedures, the BImSchG and associated environmental laws provide extensive participation and involvement rights for the public, including hearings, objections, and the right to access files. Recognized environmental associations can also assert rights to legal action according to the Environmental Remedies Act.
Neighboring Rights Claims (§§ 22, 23 BImSchG)
The Act contains specific provisions to protect neighboring legal interests against harmful environmental impacts. Private claims for injunctive relief or removal exist especially when harmful environmental impacts are caused by a facility that does not require approval.
Criminal and Regulatory Offenses
The Federal Immission Control Act also contains sanction provisions. Administrative or criminal offenses, such as unauthorized operation of facilities without approval, exceeding limit values, breach of conditions, or non-compliance with official orders, can be punished according to §§ 62 ff. BImSchG with fines or imprisonment.
Interfaces and Links to Other Legal Fields
The BImSchG is closely linked with other environmental law provisions, such as the Water Resources Act, the Circular Economy Act, building law regulations, nature conservation regulations, as well as European directives and regulations (such as the Industrial Emissions Directive). The implementation of requirements of EU environmental policy often also occurs through the BImSchG and its regulations.
Administrative Procedures and Legal Protection
Administrative Procedures
The central administrative procedures for implementing the Federal Immission Control Act are the approval and monitoring procedures. In this context, particular features of environmental law, such as public participation, environmental impact assessments, and the observance of transparency and information obligations, must be taken into account.
Legal Remedies
Against administrative acts based on the BImSchG, such as the granting or denial of approval, general administrative judicial remedies are available. Environmental associations also have the right to bring an action by way of association lawsuits in accordance with the requirements of the Environmental Remedies Act.
Significance for Environmental and Climate Protection
The Federal Immission Control Act makes a central contribution to national environmental protection and compliance with international and European environmental policy obligations. By including climate protection within its scope, particularly through the adaptation of relevant provisions, the BImSchG is integrated into climate protection and the reduction of greenhouse gas emissions.
Current Developments
Amendments to the BImSchG are often oriented towards scientific and technical developments as well as requirements of the European Union. Current topics include in particular the improvement of air quality, reduction of greenhouse gas emissions, protection against health impairments, and adaptation to new technical standards for emission limitation.

Frequently Asked Questions
How does the obligation to obtain approval under the Federal Immission Control Act (BImSchG) work?
The obligation to obtain approval under the Federal Immission Control Act (BImSchG) generally applies to facilities listed in Annex 1 of the 4th BImSchV (Regulation on Facilities Requiring Approval). Such facilities may only be constructed, operated, or significantly altered if an immission control permit has first been obtained from the competent authority. The approval procedure includes a comprehensive assessment of all environmental aspects, especially with regard to the protected goods: humans, animals, plants, soil, water, atmosphere, as well as cultural assets and property. During the approval process, the planned emissions of the facility are assessed, requirements to protect against harmful environmental impacts are imposed if necessary, and compliance with all public law regulations is ensured. For certain large-scale projects, public participation is also envisaged, during which affected citizens and public stakeholders may raise objections. The law distinguishes between formal and simplified procedures, depending on the size and potential environmental impact of the proposed facility. The decision to grant approval must include information on legal remedies and may only be issued if all requirements are met.
What monitoring and supervision obligations exist for operators of facilities requiring approval under the BImSchG?
Operators of facilities requiring approval are subject to extensive monitoring and supervision obligations under the BImSchG. According to § 52 BImSchG, facilities must be regularly monitored by the competent immission control authority. Operators are obliged to provide the authority with all documents, measurement data, and other information required for review. This specifically includes self-monitoring measures such as regular emissions measurements, which may be required by the 13th BImSchV (Regulation on Large Combustion Plants) or the 17th BImSchV (Regulation on Waste Incineration Plants). The results of such monitoring must be recorded and submitted upon request. If deficiencies are found, the operator is obliged to remedy them without delay and, if necessary, take further measures to comply with limit values or other requirements. Authorities may also carry out unannounced inspections and require corrective measures up to and including prohibition of facility operation.
What is the significance of the location principle in the legal context of the BImSchG?
The location principle holds special significance in the BImSchG. It means that when assessing whether a facility causes harmful environmental impacts on the neighborhood, the specific circumstances of the given location are decisive. The standard is whether the emissions customary in the area would be unacceptably increased by the new or altered facility. For certain protected interests—for example, in valuable residential areas or sensitive institutions like schools and hospitals—stricter conditions apply, which are specified during the approval process. The approving authority therefore always examines which uses are permissible and reasonable at the location and is guided by the values set out in the Technical Instructions on Noise Protection (TA Lärm) or the Odor Immission Guidelines. Deviations from generally applicable standards may be required to protect the neighborhood.
To what extent does the Federal Immission Control Act contain exceptions and exemption possibilities?
The Federal Immission Control Act includes several regulations concerning exceptions and exemptions. According to § 7 BImSchG, the authority may allow exceptions to certain requirements in individual cases, insofar as this is expressly provided for by statutory regulations. Such exemptions mainly concern technical regulations, minimum distance requirements, or certain measurement and monitoring obligations. The prerequisite for granting an exception is that the fundamental obligations of the law—in particular the prohibition of harmful environmental impacts—continue to be fully observed. The decision on an exemption must be made after careful consideration of all affected interests and must regularly be substantiated. So-called minor installations, i.e., facilities with very low environmental relevance, may also be exempted in whole or in part from certain obligations depending on state regulations.
What role do limit values and technical instructions play in the BImSchG?
Limit values and technical instructions play a crucial role in the BImSchG to ensure effective protection of humans and the environment. The applicable limit values can be found both in the Act itself and in numerous subordinate regulations, especially in the so-called TA Luft (Technical Instructions on Air Quality Control), TA Lärm (Technical Instructions on Noise Protection), and in various immission control ordinances (e.g., 13th to 44th BImSchV). These include specific requirements for emission and immission limit values, which must be observed as part of the approval and ongoing operation. The technical instructions also reflect the recognized state of the art and thus provide a standard for interpreting indeterminate legal terms in the Act. If established limit values are exceeded, the authority is required to order appropriate measures to reduce immissions, up to the partial or complete prohibition of facility operation.
What are the legal conditions for neighbor rights in the context of the BImSchG?
Neighbors of facilities requiring approval are granted special protection under the BImSchG. Neighborly claims in particular arise from § 5 BImSchG, which requires facilities to be constructed and operated in such a way that harmful environmental impacts on the neighborhood are excluded. In the event of emissions exceeding statutory limit values, neighbors are entitled to assert defensive claims, which can be enforced by objection and legal action within public law. During the approval process, there is also a right to participation (e.g., submission of objections in the formal process), which in certain cases leads to a comprehensive examination of private interests. However, neighbors’ rights under the BImSchG are limited to harmful environmental impacts; further forms of impairment must be pursued, if necessary, under civil law.
What are the key obligations in incident control law under the BImSchG?
Incident control law forms its own regulatory area within the BImSchG and serves to prevent and avert hazards resulting from operational disturbances or accidents involving dangerous substances. In accordance with § 17 BImSchG and the 12th BImSchV (Incident Ordinance), operators of certain facilities are obliged to take extensive safety precautions, prevent operational disturbances, and be prepared for possible incidents. This includes the development of safety concepts, internal alarm and emergency response plans, regular training of staff, and reporting and information duties toward the competent authority and the public. In the event of an incident, operators must immediately inform the authority, initiate immediate response measures, and analyze the causes. Fulfillment of these obligations is monitored through regular inspections, and violations can be sanctioned with substantial fines or shutdowns of operations.
