The Environmental impact assessment (EIA) is actually only one component of the legislation on "environmental assessments" of the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMVU). Another component here is, for example, the Strategic Environmental Assessment (SEA). The Environmental Impact Assessment Act (UVPG) brings together all measures and provides the framework for this. In general, the impact of projects on the environment should be assessed and negative effects minimized. The law also applies to wind and solar parks, for example. The UVPG contains important instruments to ensure sustainable development and came into force in 1990. It is based on various European directives and serves to transpose these guidelines into German law. Since then, the UVPG has been amended several times and the most recent amendments date from December 2023.
Objective of the UVPG
The environmental impact assessment (EIA) analyzes the potential impact of a project on various aspects such as humans, animals, plants, soil, water and air as well as cultural and natural resources. In a Report These impacts are presented and the affected public and specialist authorities can comment on them. The competent authority uses this information to make its decision on whether to approve the project. The detailed assessment is intended to ensure that projects are planned and implemented sustainably and that potential negative impacts on the environment are minimized.
The UVPG defines the procedures and requirements for environmental impact assessments. It stipulates that project developers must prepare an environmental impact study that identifies and assesses the potential impact of the project on the environment. Based on the results of the study, measures to minimize the impact are then developed and integrated into the planning process.
The main principles of the Environmental Impact Assessment Act (UVPG)
The EIA Act is based on a number of basic principles that are intended to ensure that the environmental impact assessment is carried out effectively and sustainably. The most important principles include:
Early public participation
The UVPG attaches great importance to the Early participation of the public in the planning process of a project. This enables citizens to voice their concerns and worries about potential environmental impacts and ensure that their interests are adequately taken into account.
Transparency and access to information
The EIA Act requires that all relevant information about the project and its potential impacts be made available to the public. This ensures Transparency and enables citizens to make informed decisions and actively participate in the planning process.
Consideration of alternatives
The UVPG requires that the environmental impact assessment must also include Alternatives to the planned project. This makes it possible to compare the impact of different options on the environment and find the most sustainable solution.
Phases of the EIA
ScopingIn this phase, the relevant aspects of the environmental impact assessment are identified and the scope of the assessment is defined.
Environmental impact studyIn this step, a detailed study is prepared that analyzes the potential impact of the project on the environment. This includes the identification of potential risks and the development of measures to minimize the impact.
Public participationThe public is invited to participate throughout the entire process. This can take the form of hearings, consultations or public displays of documents.
RatingBased on the environmental impact study and feedback from the public, an assessment of the project's impact on the environment will be carried out.
DecisionBased on the assessment, a decision is made as to whether the project is approved, rejected or approved under certain conditions.
Practical application examples
Environmental impact assessment is used in many different areas, such as construction, energy production, transportation and agriculture.
One example of the application of the UVPG is the construction of a new highway. Before the project begins, an environmental impact study is carried out to assess the impact of the highway on the environment. Based on the results of the study, measures are then taken to minimize the impact. In this example, there were recommendations for the construction of noise barriers or the protection of natural habitats. The same procedure can also be initiated, for example, for a major construction project by a company, in agriculture or for the designation of an industrial estate
UVPG and renewable energies
In general, an environmental impact assessment may be required for any construction or infrastructure project. However, as part of the climate targets and the goal of CO₂ neutrality, the conditions for EIAs and SEAs for renewable energy plants were relaxed or even partially lifted in the amendment of March 2023. This applies in particular to certain onshore and offshore wind turbines or solar parks and is intended to speed up the approval process.
In individual cases, only a strategic environmental assessment of the construction area concerned has been sufficient since then. Plant-related environmental impact assessments are not required for wind energy plants, the expansion of electricity grids or ground-mounted solar plants if they are larger than 20,000 m², for example, and a development plan is in place. This corresponds to an area of around 2.6 soccer pitches on which a 2.36 MWp solar park could be erected. By way of comparison, the largest ground-mounted system currently being built in Germany is 650 MWp on an area of around 5 million m². In principle, there are and have been PV roof systems or Solar carports on already sealed surfaces from an UVPG Not affected.
Criticism of the Environmental Impact Assessment Act (UVPG)
The UVPG is a complex law that prescribes an extensive procedure for carrying out environmental impact assessments. This can lead to Delays and high costs especially for smaller projects or projects with a limited budget.
Lack of transparencyEIA processes and decisions are often criticized for not being sufficiently transparent. This can lead to mistrust and dissatisfaction among the public, which impairs confidence in the correctness of the decisions.
Public participationAlthough it is a cornerstone of the UVPG, there is criticism that citizens' concerns may not be sufficiently taken into account. Some argue that public participation takes place too late in the process. Others that decisions have already been made before the public is heard.
Influence: There are concerns about possible manipulation or influence on the EIA process by the project sponsors or other interest groups. This may mean that the results of the EIA are not objective and unbiased.
Lack of alternative solutionsSome critics argue that the EIA sometimes does not sufficiently consider alternative solutions or locations for a project. This can lead to less environmentally damaging or more sustainable options being overlooked.
Incomplete assessment of the environmental impactIt is often criticized that the EIA does not adequately consider all potential environmental impacts of a project. This can lead to certain impacts being underestimated or overlooked.
Lack of involvement of technical expertsEIA requires a multidisciplinary assessment of environmental impacts. It is sometimes criticized that not enough technical experts are involved in the process to ensure a sound assessment.
Long-term monitoringAfter a project has been completed, it is difficult to monitor the long-term effects and impacts on the environment. This can lead to long-term environmental impacts not being adequately recorded or assessed.
Political influenceIn some cases it is argued that political interests can influence the results of the EIA, especially when it comes to controversial or politically sensitive projects.
Examples of successful environmental impact assessments
Despite the challenges and controversies, there are many examples of successful environmental impact assessments that have promoted sustainable development.
In Germany, the EIA is often used for large infrastructure projects such as Offshore wind farms carried out. One example of this is the Alpha Ventus offshore wind farm in the North Sea. Prior to its construction, comprehensive EIAs were carried out to assess the potential impact on the marine environment, fisheries and other stakeholders. The results led to measures to minimize environmental impacts and to create protection and compensation measures for sensitive ecosystems.
An EIA is also carried out in Germany for major transport infrastructure projects such as highway expansions or the construction of new high-speed rail lines. One example is the EIA for the Expansion of the A7 freeway between Hamburg and Hanover. This EIA included extensive studies on noise, air and water pollution as well as the impact on nature conservation areas. The results led to adjustments in the planning process in order to minimize environmental impacts.
The construction of new industrial plants often requires an EIA to assess the potential impact on the environment and the health of local residents. One example is the EIA for the construction of a Chemical parks in a rural area. The EIA examined impacts such as air pollution, waste disposal and water consumption. Based on the results, measures were implemented to control emissions and prevent pollution.
Conclusion on the environmental impact assessment (UVPG)
The Environmental Impact Assessment Act (UVPG) is an important instrument for ensuring sustainable development. Since its introduction in 1990, the UVPG has helped to promote sustainable development and integrate environmental protection concerns into planning and approval processes.
The main objective of the UVPG is to comprehensively analyse the impact of projects on the environment and to take measures to minimize negative effects. Environmentally compatible solutions are to be found through early public participation, transparency and the consideration of alternatives.
Although the UVPG makes an important contribution to environmental protection, there are also many points of criticism. The most important are the Time delays and the additionaln Costs for projects. These include concerns about transparency, public participation, potential influence, insufficient consideration of alternative solutions and incomplete assessment of environmental impacts. Despite these challenges, there are many successful examples of environmental impact assessments in Germany and Europe.
Overall, the environmental impact assessment remains an essential instrument for incorporating environmental concerns into planning and approval processes and ensuring that environmental interests are taken into account in a balanced manner. Through continuous improvements and adjustments, the Environmental Impact Assessment Act can continue to contribute to supporting sustainable development in Germany.
