They establish guidelines, standards, and regulations to ensure the proper evaluation of renewable energy projects. These bodies monitor compliance, review assessments, and provide guidance on best practices for environmental impact assessment and management.

Several case studies provide insights into effective environmental impact assessment in renewable energy projects. These studies demonstrate the importance of comprehensive evaluations, stakeholder engagement, and adaptive management approaches to address environmental concerns successfully.

Assessing the environmental impact of renewable energy projects is crucial for achieving sustainable development goals. By evaluating key factors such as land and habitat impact, wildlife and biodiversity impact, water resources impact, noise and visual impact, social and cultural impact, and cumulative impact, we can ensure that renewable energy projects are implemented in an environmentally responsible manner.

Through robust environmental impact assessment processes, mitigation measures, and stakeholder engagement, we can strike a balance between renewable energy development and environmental conservation.

Assessing Environmental Impact: Renewable Energy Projects published on 03 July Introduction Renewable energy projects, such as wind farms, solar power plants, and hydropower installations, offer substantial benefits in terms of clean energy production.

Understanding Environmental Impact Assessment EIA Environmental Impact Assessment EIA is a systematic process used to identify and evaluate the potential environmental effects of a proposed project or development.

Key Environmental Factors in Renewable Energy Projects When assessing the environmental impact of renewable energy projects, several key factors need to be considered: --Land and Habitat Impact Renewable energy projects often require a significant land area for installation.

Mitigation and Environmental Management Plans Based on the findings of the environmental impact assessment, mitigation measures and environmental management plans are developed. Most of these renewables have unique characteristics that are very different form conventional generation. Special models and analytical techniques are required to assess their impact on system reliability and security, and to ensure an acceptable performance level.

Powertech provides such technologies based on our DSA Tools software package and the dynamic security assessment approach implemented for many of our clients.

Once impacts have been identified and predicted, the next step is to evaluate the degree of impacts and whether they are considered acceptable or not.

This is a key step in the impact assessment process as the results may be directly translated into recommendations for decision-makers concerning the wind energy project. In the context of a World Heritage property, this step focuses on the evaluation of the significance and characteristics of an identified impact on the individual attributes conveying the OUV of a World Heritage property.

Nevertheless, overall impacts on the OUV and other values will also need to be assessed. How can impacts be evaluated?

There are multiple methodologies for the evaluation of impacts and several ways of presenting them such as matrixes, colour-codes and tabular visualizations of impacts. An appropriate methodology should be selected according to the nature of the proposed project and the types of impacts predicted.

An overview of evaluation methods is presented in the Guidance and Toolkit for Impact Assessments in a World Heritage Context. For more detailed information related to assessing potential visual impacts, see Note 5 and for cumulative impacts see Note 6.

The impacts of a wind energy project need to be evaluated with regard to all project phases considering each step in the project lifecycle , as different impacts might occur at each phase design and planning , construction , operation or end-of-life phase.

For example, the construction of wind turbines could cause high level impacts that need to be avoided or mitigated, but these will be redundant later during operation and maintenance phases, which might create other impacts.

If the proposed wind energy project will potentially have negative impacts on the OUV, three conclusions could be reached as a result of the evaluation:. Positive impacts of the proposed wind energy project will also need to be highlighted as part of the assessment evaluation process.

Positive impacts identified, predicted and evaluated are fundamental to understand the project itself and its possible relevance to rights-holders and stakeholders. Positive impacts of the proposed wind energy project should primarily be considered against the objectives set for the proposed actions, and the following conclusions could be reached as a result of their evaluation:.

If the impact is neutral or positive on the OUV, it can proceed. However, if it has a negative impact on the OUV overall as for example, the wind turbines will pose an adverse visual impact for a cultural landscape with important visual values these will need to be avoided for example, the wind turbines or a problematic transformer station be moved further from the boundaries of a site or mitigated for example, using subsoil cables for transmitting electricity from the wind farm , otherwise this aspect of the proposal or the project itself is not to proceed.

The evaluation of impacts and their significance on the attributes and the OUV overall, will lead to the need to explore:. In the World Heritage context, the positive impacts must not be weighed up against any negative impact the proposed project might have on the OUV of a World Heritage property.

As the OUV is irreplaceable, offsetting is not an option. A wind energy project with a significant adverse impact on the OUV of a World Heritage property should be considered unsuitable and should not be granted permission. Any mitigation attempts to balance out potential negative impacts on the OUV with otherwise positive impacts reflects an improper approach and is unacceptable from a World Heritage protection point of view.

Should not all wind energy project be considered as positive by default? As wind energy installations are linked to renewable energy projects, they could be considered by default as initiatives with an overall positive impact in terms of their contribution to combating the ongoing climate emergency and their role in achieving the Sustainable Development Goals.

However, due to the Outstanding Universal Value of World Heritage properties, negative impacts of planned installations on these areas should be avoided where and whenever possible, and alternatives should always be investigated through an impact assessment process.

The impact assessment process will need to assess the consequences of a proposed wind energy project from all relevant aspects, including its benefits and positive impacts. Wider benefits of these projects could include social aspects, such as access to clean energy, opportunities for local employment and reduced energy prices for local communities.

Nevertheless, these benefits should not be achieved at the cost of negative impacts on World Heritage properties. Alternative solutions can be found, for example by finding other locations for the whole wind farm or its ancillary facilities, or by reducing their size and scale. Mitigation and enhancement.

What are the reasonable alternatives to the proposed wind energy project that avoid or minimize any negative impacts and achieve the objectives of the proposed action? How can negative impacts be avoided or minimized, and positive impacts achieved and enhanced?

The impact assessment process should identify and evaluate the possible negative and positive impacts of the proposed wind energy project and clearly state which ones are considered to be acceptable or not acceptable with regard impacts on the OUV of the property, its other values and in relation to rights-holders and local communities.

In the World Heritage context, a case-by-case assessment is needed to consider how to proceed if potential negative impacts have been identified on values of a World Heritage property. Some attributes that convey the OUV might not be particularly sensitive to impacts of a proposed wind energy project and certain very low impacts might not need mitigation.

Other attributes might be more sensitive to the same type of impact, depending on the characteristics of the OUV that is unique for all World Heritage properties. In these cases, mitigation should be considered to avoid or minimize the negative impacts.

Concerning impacts on values that are not part of the OUV and attributes of the World Heritage property, the mitigation measures might take a less strict approach, especially when these would help safeguard the broader societal values derived from the project.

The proposed project-specific mitigation measures, therefore, need to consider a matrix that includes both specificities of the OUV, the attributes that convey the OUV and the other values, as well as the elements and characteristics of impacts derived from the proposed wind energy project and its different project phases.

See also the Guidance and Toolkit for Impact Assessments in a World Heritage Context for a more detailed explanation concerning the mitigation measures.

Examples for mitigating negative impacts. Rectifying, reducing or offsetting negative impacts. Rectifying and reducing negative impacts, in general, are not considered to be suitable tools for mitigating negative impacts in the World Heritage context.

Nevertheless, these methods might be used for mitigating negative impacts on other values that are not related to the OUV and attributes of a World Heritage property. This solution is acceptable only if within a reasonable timeframe, there are no foreseen negative impacts on the OUV overall.

Overall negative impacts of a wind energy project could not be rectified by calculating with rehabilitation works after the licensing period of operation 20 to 30 years expires and potentially a wind farm gets dismantled and the land it occupies gets rehabilitated.

Reducing negative impacts encompasses actions that aim to decrease its impact level, but not to a level where there would be no noticeable impact. Offsetting means compensating for any negative impact that could not be avoided, minimized, rectified or reduced through providing positive measures.

As the OUV is irreplaceable, this method for mitigating negative impacts is unacceptable in the World Heritage context. Case study. Specific guidance on the identification, evaluation and mitigation of impacts by wind energy farms and installations is provided by IUCN and The Biodiversity Consultancy in the resource manual Mitigating Biodiversity Impacts Associated with Solar and Wind Energy.

The document offers step-by-step guidance in the identification and assessment of impacts throughout the project lifecycle — early planning, project design, construction, operations, closure and decommissioning or repowering — of both onshore and offshore wind and solar farms.

Please note that the International Union for Conservation of Nature IUCN , an advisory body of the World Heritage Committee considers large- and industrial-scale infrastructure incompatible with the objectives and the conservation outcomes of Natural World Heritage properties.

As wind energy projects by default should have a positive impact in relation to the Sustainable Development Goals and reducing the negative impacts of climate change, the positive impacts of these proposals need to be at the focus of the entire impact assessment process and ensure that the positive elements of the wind energy projects are not lost in the project development phase.

As Target 7. Therefore, a feasible balance should be found by creative problem-solving approach, to meet both interests. Examples for enhancement of positive impacts.

A key concern for mitigation and enhancement measures is ensuring their effective implementation beyond the impact assessment process. They might be used by the relevant authority as conditions in the permit and licensing documents for the construction and operation of the wind energy facility.

In any case, the mitigation and enhancement measures should become a coherent part of the wind energy project cycle from planning to end of life options and a clear framework needs to be provided to ensure that the following aspects are taken care of:.

The above aspects become even more important if the mitigation and enhancement measures are not directly linked to the planning and construction phase, but rather the maintenance or the end-of-life actions of the wind energy project.

Following-up mitigation measures. The effective implementation of mitigation measures requires the establishment of clear agreements with the wind energy developer. The implementation of mitigation measures should be included in management and operational documents dealing with the construction phase, the long-term operation of the wind energy project and responsibilities concerning decommissioning once the lifecycle is exhausted.

All these pieces of information should be an integral part of the licensing documents, the Environmental and Social Management Plan that guides actions on the ground when the contractor implements the actions and other relevant project management plans.

These documents should be available for all relevant parties, throughout the operational phase of wind energy facilities. With regard to the processes in the impact assessment concerning the mitigation of negative impacts and the development of project alternatives, the evaluation of impacts can be and if needed should be an iterative process which is repeated if new information becomes available or if the proposed project is revised to assess the impact of alternative project option s.

It is important to keep in mind that the evaluation of impacts is not the end of the process but rather the key moment of interaction with decision-makers. The results should be formulated in a way to clearly define the possible impacts stemming from the project and the possible mitigation measures.

If the project is considered to have no negative impact the recommendation should consider the definition of elements and key considerations to be included in the licensing process. Involvement of rights-holders and other stakeholders. The participation of right-holders, local communities and other stakeholders is key throughout an impact assessment.

It is, therefore, important to engage with them in this step as well, as rights-holders and other stakeholders should have the chance to express their perspectives and understand the potential impacts of the proposed project on their livelihood.

How should the impact assessment process and its conclusions be communicated to interested parties, including rights-holders and other stakeholders? To be effective and to fulfil its objectives, an impact assessment process should result in a report made available for all interested parties.

It is important to ensure that clear information is provided on the methodology employed for the assessment and clear conclusions are conveyed.

It is equally important that the language of the report is clear for both the decision-makers and for right-holders and other stakeholders concerning the analyses and the recommendations as well.

The level of detail needed, and the amount of information included in the report will depend on the complexity of the proposed wind energy project. The report should use and reflect the information, analyses and assessment carried out during the impact assessment process.

Within this frame, it will need to focus primarily on:. The report structure is advised to follow the step-by-step development of the impact assessment process. Nevertheless, impact assessment reports might need to follow format- or content-wise national regulations or guidance documents.

Ensure that World Heritage is addressed in the report. An impact assessment process for the identification and evaluation of the impacts of a wind energy project on a World Heritage property is often part of a wider Environmental Impact Assessment EIA or Environmental and Social Impact Assessment ESIA that is normally a requirement and obligation for project proponents under the national legal framework this is the case for all EU Member States.

In these cases, it is highly important that the assessment and also the report adequately address the impacts on the OUV and attributes of the World Heritage property in question.

Reviewing the report. Has it been carried out aligned with the relevant legal and professional framework and did it adequately consider the impacts on the OUV of the World Heritage property? The aim of reviewing the report is to determine whether the applied assessment methodology and the outcomes are adequate, if it has fully complied both with the relevant legal and professional framework and the established Terms of Reference, and moreover, if it is fit for purpose in terms of transparency and usability.

The review process it is an important step to ensure quality control; it can be conducted in different ways and at multiple levels. It is often mandatory, especially in countries, which legislation includes an Environmental and Social Impact Assessment EIA or ESIA process.

The review is often carried out by a government agency with a specific mandate or by an external independent reviewer team through a transparent process. The review must provide a clear description of the assessment process, the information used, and its final conclusions and recommendations.

Every effort should be made to ensure that:. In general terms, the review of an impact assessment will result in one of the two following outcomes:. Making the report available for rights-holders and other stakeholders and UNESCO.

The report should also be made available for rights-holders and other stakeholders to allow them to comment and check how their views and comments have been taken into account and how these influenced the project proposal and the assessment. In some countries, the report is made available for public review for example, through an online platform , allowing further room for comments.

The report of the impact assessment, in the reviewing stage, is a useful annex to this notification that allows both the World Heritage Centre and the Advisory Bodies to carry out their evaluation on the proposal and the report itself and provide feedback to the State Party often in the form of a Technical Review prepared by the Advisory Bodies, ICOMOS or IUCN.

Is the proposed wind energy project the best possible option also considering other possible alternatives? Under what terms should the proposed wind energy project be approved? Decisions are made throughout the impact assessment process as described in steps 1 to 8. The final impact assessment report provides decision-makers with clear conclusions and recommendations.

Based on those recommendations and the evidence that led to them, the relevant national, regional or local authorities should consider one of these three options:.

How the impact assessment result relates to decision-making of the UNESCO World Heritage Committee? This might be the case if an impact assessment does not consider the impacts of the proposed project on the OUV of a World Heritage property, which can happen when the proposal is not within the boundaries of the property or its buffer zone, but also if the methodology followed for assessing impacts were inadequate.

The World Heritage Committee might regard the approved project incompatible with fulfilling the obligations of a State Party under the World Heritage Convention and request the State Party to rectify the situation even if the project has been implemented.

On one hand, this may lead to national authorities facing lengthy legal procedures and having to pay the project developer financial compensation.

On the other hand, if the proposed or implemented project poses potential or ascertained threat for the OUV of the World Heritage property, it may lead to its inscription on the List of World Heritage in Danger See paragraphs of the Operational Guidelines or its deletion from the World Heritage List See paragraphs to of the Operational Guidelines.

How should the agreed mitigation measures be implemented? What should be done to monitor and manage the implementation of the proposed action?

When a wind energy project is approved and can be implemented, the information and recommendations that result from the impact assessment process should be incorporated in the relevant project documentation and contracts, such as the licensing agreement and should be part of an Environmental and Social Management Plan ESMP.

The impact assessment report itself will be the basis to develop a set of follow-up actions. The complexity of the required mitigation and enhancement measures and other follow-up actions will also depend on the level and complexity of the wind energy project.

While a small project might only require the preparation of a list of measures and actions needed, a major, large-scale wind energy project will require the drawing up of the ESMP. The relevant heritage authorities and experts from the impact assessment will need to be consulted in the development of this document, which will become part of the contract documentation of the project.

The mitigation and enhancement measures and other follow-up actions are to be implemented and monitored together with the wind energy project. The follow-up plan or the ESMP should include clear monitoring procedures to ensure that the recommendations of the impact assessment report are adequately and effectively implemented and that no unexpected further impacts arise from the project, which may need immediate managing.

The implementation of the follow-up phase needs to be ensured primarily by the project developer and the wind energy site manager. The National Focal Point for World Heritage is also expected to follow up on implementation of the World Heritage Committee Decisions and Recommendations of the Advisory Bodies in this regard.

The Guidance and Toolkit for Impact Assessments in a World Heritage Context includes a full set of follow-up activities. Please check these for developing measures in relation to wind energy projects.

What if changes are needed for a wind energy facility within its lifecycle? Considering that a wind energy project may change during its lifecycle i. This could imply a decision to dismiss the decommissioning process in favour of repowering, often with the installation of technologically more advanced infrastructure: the enlargement of existing facilities or construction of new wind turbines, modern ancillary facilities, new access tracks to the wind farm site, etc.

In these cases, a new impact assessment process should be initiated to ensure that after its redesigning, the proposed new elements and the wind energy facility as a whole are adequately assessed before permission is granted. Furthermore, it should be ensured that it will not threaten the OUV of a World Heritage property.

This is a necessary exercise as during the years the context of a World Heritage property may also change, for example, through the construction of other wind farms or other types of projects in the surrounding areas. These may add up to impacts and call for the assessment of cumulative impacts.

The needed actions might already be identified and included in the management systems in place either the ESMP or the management system of the World Heritage property. Monitoring the follow-up activities and measures. The step-by-step guidance assists those involved in carrying out an ESIA or any type of stand-alone assessment of impacts of a wind energy project proposed in relation to a World Heritage property.

Although it is less likely that a project will be planned within a property, even projects within the buffer zone or the wider setting of a World Heritage property may have an impact on its OUV.

The step-by-step guidance focuses specifically on information needed for the assessment of wind energy projects and when indicated, it should be used in conjunction with the Guidance and Toolkit for Impact Assessment in a World Heritage Context.

For each step or element of the ESIA, this guidance tool offers an overview of the key information needed for the assessment of the potential impacts of wind energy projects with specific reference to impacts on the OUV of a concerned World Heritage property. If used in other places of the guidance, it refers to the impact assessment processes in general terms.

As impact assessments are not linear processes but iterative processes, any changes to the proposed project or new information will need to be integrated into the process as they it becomes available. This may also result in the need to revise the process as it develops.

To this end, a proactive problem-solving approach will need to take be adopted throughout the entire impact assessment process, as a one of the fundamental purposes of an impact assessment is to consider alternatives and mitigation measures to the impacts on the OUV of World Heritage properties concerned.

The findings and result of the ESIA are documented in an impact assessment report with clear recommendations for decision-makers and explanations of these proposed recommendations to all interested parties including right-holders and other stakeholders.

The development of an ESMP is regarded as a good practice that allows well-founded monitoring for all interested parties including monitoring of the agreed mitigation measures and other safeguards.

National level regulations on how to conduct an Environmental Impact Assessment or an Environmental and Social Impact Assessment are present in most countries, and in many cases, these are complemented by guidance documents that further expand on methodologies and good practices.

In some cases, there are specific guidance on how to assess impacts of wind energy projects in relation to protected areas. Impacts can also be both negative and positive and can arise from projects planned to be located within a World Heritage property, its buffer zone or its wider setting.

Identifying and evaluating impacts in relation to the OUV of World Heritage properties is a complex task that requires considerable expertise and a thorough evaluation of all relevant information. The most evident impact that comes to mind when thinking about wind energy projects is usually their visual impact see for details Note 5.

However, impacts can be more than visual — inadequately planned wind farms, for example, can be located on migratory routes or within sensitive biodiversity areas, or disturb significant archaeological sites.

When looking at the impact of wind energy projects, it is also important to bear in mind that a project may have different impacts over its lifecycle as well as several impacts at the same time. Such compound of impacts should not be analysed in isolation but considered cumulatively an overview of cumulative impacts can be found in Note 6.
