The term “EIA” actually refers to two completely different things depending on your context. In the Netherlands, EIA stands for Energie-investeringsaftrek, a tax deduction scheme for energy-saving business investments. Under EU law, EIA refers to Environmental Impact Assessment, a mandatory review process for major development projects. This article unpacks both meanings, clarifies what data and resources each involves, and helps you find exactly what you need.
Where can EIA data be found online?
Where you find EIA data depends entirely on which EIA you mean. For the Dutch Energy Investment Allowance, the primary source is the Dutch Enterprise Agency (RVO), which publishes the Energy List, application guidelines, and budget information. For EU Environmental Impact Assessments, project data is published through national approval authorities and, in some cases, the European Commission’s own databases.
For the Dutch EIA scheme, the RVO website is your single most reliable starting point. It hosts the current Energy List (Energielijst 2026), application portals, and detailed guidance on qualifying investments. The Energy List is updated annually, so always make sure you are consulting the version relevant to your investment year.
For EU Environmental Impact Assessments, data is more decentralised. Individual EU Member States are responsible for conducting and publishing EIA procedures through their national or regional competent authorities. Some countries maintain searchable online registers of EIA decisions, while others publish information project by project through planning or environmental agencies.
What datasets does the EIA actually publish?
The Dutch EIA scheme publishes the Energy List as its core dataset, a structured list of qualifying energy-saving investments, each assigned a specific code. It also publishes annual budget figures, application statistics, and guidance documents. For 2026, the total EIA budget is €460 million, giving businesses a clear sense of the scheme’s scale.
The Energy List itself is the most practically useful document within the scheme. It contains two categories of qualifying investments:
- Clearly defined investments with a specific code, where the qualifying criteria are fixed and transparent
- Tailor-made (generic) investments that result in substantial energy savings and meet a defined savings standard, even if they do not appear under a specific code
For EU Environmental Impact Assessments, the “dataset” is not a centralised database but rather a body of project-specific documentation. Each assessed project must include a report covering the project’s location, design, and size; its potential significant effects on population, human health, biodiversity, land, soil, water, air, climate, landscape, material assets, and cultural heritage; reasonable alternatives considered; and measures to avoid, prevent, reduce, or offset likely environmental impacts. This documentation is made available to the public as part of the mandatory participation process.
How does the EIA API work?
Neither the Dutch EIA (Energie-investeringsaftrek) nor the EU Environmental Impact Assessment framework operates through a public API in the conventional sense. The Dutch scheme is administered through RVO’s digital application portal, which is a form-based submission system rather than a machine-readable data interface. EU EIA data is similarly not available through a standardised API, as it is managed at the national level across Member States.
If you are looking for programmatic access to energy investment or environmental data in Europe, you are more likely to find relevant resources through Eurostat, the European Environment Agency (EEA), or national energy agencies that publish structured datasets. These organisations do offer data downloads and, in some cases, API access for broader energy and environmental statistics.
For businesses working with the Dutch EIA scheme specifically, the practical “interface” is the RVO digital portal, where applications must be submitted within three months after the order for the qualifying investment is placed. There is no workaround to this requirement, the submission must be made digitally and on time.
What tools can query EIA data without coding?
For the Dutch Energy Investment Allowance, no specialist tools are needed. The RVO website provides the Energy List as a downloadable document, and the application process is handled through a standard digital portal. Any entrepreneur or their advisor can search the Energy List directly to check whether a specific investment qualifies, without any technical skills required.
For EU Environmental Impact Assessment data, the approach is similarly manual. Most national competent authorities publish EIA documentation through their planning or environmental agency websites, which are searchable using standard web search tools. There is no EU-wide query tool that aggregates EIA decisions across Member States into a single searchable interface.
If your goal is to research whether a specific type of project requires an EIA, the most reliable no-code approach is to consult the relevant national authority directly. Projects that automatically require an EIA include nuclear power stations, long-distance railways, motorways, express roads, hazardous waste disposal installations, and dams of a certain capacity. For other project types, including urban and industrial development, roads, tourism development, and flood relief works, the decision is made on a case-by-case basis or by applying criteria such as project location, size, or type.
How do you download bulk EIA data files?
Bulk download options for EIA data are limited in both contexts. The Dutch RVO publishes the Energy List as a downloadable PDF or structured document each year, which is the closest equivalent to a bulk data file within the scheme. There is no bulk export of application records or tax deduction data available to the public, as this information is commercially sensitive.
For EU Environmental Impact Assessments, bulk access to project documentation is not available through a centralised download mechanism. Individual project reports must be accessed through the relevant national or regional authority. Some Member States maintain registers that allow you to filter and access multiple EIA decisions, but the format and accessibility vary significantly by country.
If you need to work with large volumes of energy or environmental data for research or analysis purposes, the most practical route is to use open data portals from Eurostat or the European Environment Agency, which do offer structured, downloadable datasets on energy consumption, emissions, and environmental indicators across EU Member States.
What are the most common issues when accessing EIA data?
The most common issues when accessing EIA data fall into a few predictable categories, whether you are dealing with the Dutch tax scheme or the EU environmental assessment framework.
- Confusing the two meanings of EIA. Because “EIA” refers to both the Dutch Energie-investeringsaftrek and the EU Environmental Impact Assessment, many searches return a mix of results from both frameworks. Always clarify which EIA you need before starting your research.
- Using an outdated Energy List. The Dutch Energy List is updated annually. Investments that qualified in a previous year may not qualify in 2026, and new qualifying technologies are added regularly. Always verify against the current Energielijst 2026.
- Missing the application deadline. For the Dutch EIA scheme, the application must be submitted digitally within three months after the order is placed. Missing this window disqualifies the investment entirely, regardless of whether it appears on the Energy List.
- Assuming all investments automatically qualify. To qualify for the Dutch EIA, the investment must be listed on the Energy List as a company asset, must be unused, and must meet the specific requirements defined for that code. Investments not on the list may qualify under a generic code, or a proposal can be submitted to add them, but this must be done before 1 September 2026, and the procedure is conducted in Dutch.
- Navigating decentralised EU EIA data. Because EU Environmental Impact Assessment data is managed at the national level, there is no single portal. Researchers often need to identify the correct national or regional authority before they can locate relevant project documentation.
Understanding these friction points in advance saves significant time and reduces the risk of costly errors, particularly for businesses planning to claim the Dutch tax deduction.
How RIFT Approaches Industrial Decarbonisation
While this article focuses on EIA frameworks and data access, it is worth noting that for industrial companies navigating sustainability decisions, the regulatory and financial landscape around clean energy investment is only one part of the picture. The other part is finding technologies that actually work at scale.
That is where we come in. At RIFT, we have developed Iron Fuel Technology (IFT) as a practical, high-efficiency solution for decarbonising industrial heat, one of the largest remaining sources of industrial CO₂ emissions. Our Iron Fuel Boiler delivers:
- Up to 95% energy efficiency, outperforming many conventional fossil fuel systems
- Near-zero direct CO₂ emissions during combustion (just 10 kg CO₂/MWhth, stemming solely from a pilot safety flame)
- RIFT claims the lowest NOₓ emissions of any fuel, at under 5 Mg/MJ, based on our demo-scale results
- Seamless integration with existing industrial boiler infrastructure
- A fully circular fuel cycle, iron powder burns cleanly, leaves only iron oxide, which is regenerated using low-carbon hydrogen
Our technology is demonstrated at TRL7 (megawatt-industrial scale) and is already moving into commercial deployment, with the world’s first commercial Iron Fuel Technology contract signed with Kingspan Unidek. Backed by €113.8 million in funding, we are scaling from pilot to commercial reality.
If you are a sustainability manager evaluating industrial heat solutions for your organisation, we would welcome the conversation. Get in touch with our team to explore whether Iron Fuel Technology is the right fit for your decarbonisation goals.
Frequently Asked Questions
Can a company claim the Dutch EIA deduction for investments in Iron Fuel Technology or other emerging clean energy systems?
Potentially yes, but it depends on whether the specific technology appears on the current Energy List (Energielijst 2026) under a defined code, or whether it qualifies under a generic (tailor-made) investment category based on substantial energy savings. If the technology is not yet listed, companies can submit a proposal to have it added, but this must be done before 1 September 2026 and the procedure is conducted in Dutch. Engaging an energy tax advisor early in the process is strongly recommended to assess eligibility before placing an order.
What is the actual financial benefit of the Dutch EIA scheme, and how is the deduction calculated?
The Dutch EIA allows businesses to deduct a percentage of the investment cost of qualifying energy-saving assets from their taxable profit, on top of the standard depreciation allowance. This reduces the effective cost of the investment by lowering the tax burden in the year the deduction is claimed. The exact deduction percentage is set annually, so businesses should consult the current RVO guidance or a tax advisor to calculate the precise benefit for their specific investment amount and tax situation.
What happens if I miss the three-month application deadline for the Dutch EIA scheme?
Missing the deadline is a hard disqualifier — there is no grace period or appeals process that restores eligibility once the three-month window after placing the order has passed. This makes it critical to identify qualifying investments and initiate the RVO application process at the same time as, or immediately after, placing the order. Building this step into your procurement workflow, rather than treating it as an afterthought, is the most reliable way to avoid losing the deduction.
How do I determine whether a specific development project in my country requires an EU Environmental Impact Assessment?
The starting point is the EU EIA Directive (2011/92/EU, as amended by 2014/52/EU), which defines two categories of projects: those that always require an EIA (Annex I, such as nuclear power stations, motorways, and large dams) and those subject to a case-by-case screening by national authorities (Annex II, including many industrial, infrastructure, and urban development projects). To get a definitive answer for your specific project, contact the relevant national or regional competent authority in your country, as they are responsible for applying the Directive’s criteria to local circumstances and can confirm whether a full EIA is required.
Is EIA data from other EU countries available in English, or will I need to navigate national-language sources?
In most cases, EU Environmental Impact Assessment documentation is published in the official language of the Member State where the project is located, which means researchers working across multiple countries will typically encounter a mix of languages. Some larger Member States publish summaries or guidance in English, particularly for cross-border projects, but this is not guaranteed. Using translation tools alongside official national environmental agency websites is a practical workaround, and in some cases, the European Commission’s own publications on EIA policy provide English-language overviews of how individual countries implement the framework.
Are there professionals or advisors who specialise in helping businesses navigate the Dutch EIA application process?
Yes — energy tax advisors and specialist consultancies in the Netherlands routinely help businesses identify qualifying investments, match them to the correct Energy List codes, and manage the RVO application process within the required deadlines. This is particularly valuable for complex or high-value investments, or where a generic (tailor-made) qualification route is being pursued. Your industry association or accountant can often provide a referral, and the RVO website itself offers guidance documents that can help you assess whether specialist support is warranted for your situation.
Can a single investment qualify for both the Dutch EIA tax deduction and other sustainability incentives, such as the SDE++ subsidy?
In many cases, yes — the Dutch EIA deduction can be combined with other support schemes, but the specific rules around stacking incentives depend on the nature of the investment and the schemes involved. The SDE++ (Stimulering Duurzame Energieproductie en Klimaattransitie) targets renewable energy production and CO₂ reduction projects, while the EIA focuses on energy-saving investments, so the two can sometimes apply to different aspects of the same project. Always verify the combination rules with RVO or a qualified advisor before assuming both apply, as certain restrictions on cumulating state aid may limit what can be claimed simultaneously.
