Frequently Asked Questions



What is ISCC?

ISCC is a globally applicable sustainability certification system and covers all sustainable feedstocks, including agricultural and forestry biomass, bio-based and circular materials and renewables. Certification under the ISCC standard assures a fully transparent and deforestation-free supply chain and the protection of land with high biodiversity value and high carbon stock. The ISCC standard complies with human, labor and land rights, as well as good management practices. Furthermore, ISCC provides the methodology, rules, and guidelines for calculating and verifying greenhouse gas emissions and emission reductions.

Please find further information about the ISCC certification system in the ISCC System Documents.

What are the benefits of a membership in the ISCC Association and how does my organization or myself become a member?

Certification processes and requirements


Which certification is right for me?

The relevant certification system depends on the requirements of your target market (e.g. on the applicable regulatory requirements). Below you can find a short summary – a detailed overview is available on the ISCC website.

  • ISCC EU: Biofuels in EU
  • ISCC PLUS: Circular and bio-based products, renewables, food, feed, industrial applications and biofuels outside EU
  • ISCC CORSIA and ISCC CORSIA PLUS: Sustainable aviation fuels (SAF) eligible under the ICAO CORSIA scheme
  • ISCC Solid Biomass NL: Energy
  • ISCC Non-GMO: Food, feed, completely independent from the general ISCC certification on environmental, social and economic sustainability on farm level

How many certificates do I need?

Certificates are site specific, which means that per legal entity and per location one certificate is necessary. This means that one legal entity can have several registrations and certificates – one for each certified operational site. Under this certificate several inputs / outputs, raw material categories and market activities (processing, storing, etc.) can be covered.

Can I get certified under several ISCC systems?

It is possible for you to get certified under multiple ISCC systems. These include ISCC EU, ISCC PLUS, ISCC CORSIA; ISCC Solid Biomass NL and ISCC Non-GMO. There are no limits on the combination – you are free to choose what suits your needs best. For ISCC EU and PLUS combined audits are already possible. Furthermore, if you add an additional certification scheme to the same operational unit, you do not need to apply for a new registration number. It is sufficient you get in touch with us via and we will extend your current registration.

How can I get ISCC certified?

The ISCC certification process includes these main steps:

  1. Choose a recognized Certification Body (CB) and to sign a contract with them.
  2. Get registered with ISCC and fill out the ISCC registration form
  3. Get audited by your certification body and receive your ISCC certificate
  4. Handle sustainable material and use ISCC logos and claims

The first step to become ISCC certified is to choose a certification body (CB) and to sign a contract with them. A list with all recognized CBs is provided on our website. Then you must get registered with ISCC, fill out a registration form, which you find here. After the audit has been conducted successfully, the certificate will be issued from your certification body.

Which certification bodies does ISCC cooperate with and do they have auditors in all countries?

Please find all the certification bodies that ISCC cooperates with here on our website. Many of them work on a global basis. Please get in touch with the certification body’s contact person for more information regarding your specific set-up.

Please note that ISCC does not give recommendations on which certification body to choose. To find out which certification bodies are active in your country, you may browse through the valid ISCC certificates of companies located in your country by applying the search function.

How can I change Certification Bodies?

If you change certification bodies, you must inform ISCC. Please send us an email to stating the name of the new certification body and the date the new contract was signed.

If a system user decides to change their certification body, requirements with regards to the integrity of the system must be met, e.g., regarding the provision of audit reports to the new certification body. If a System User changes the CB twice within a period of five years, the CB newly contracted by the System User with the second change has to apply a higher risk level for the next scheduled audit, i.e. the risk level must be higher than the risk level applied for the previous audit. All requirements can be found in ISCC EU system document 103 Requirements for Certification Bodies and Auditors.

How can I change my registration details?

In order to change data in a submitted registration, please send an email to stating the name of your company, your registration number and what you would like us to change.

How long is an ISCC certificate valid?

The validity of the ISCC certificate is one year – precondition is a successful audit.

How much do I have to pay for an ISCC Certificate?

The certification fees are based on the total turnover of the registered operational unit. Please find here the ISCC fee structure. The fees cover the costs for the registration process and the certificate. Please note that additional costs occur for the audit, charged by the CB. ISCC cannot give an estimate of those costs, as they depend on the scope of the audit.

Your CB will be able to answer specific questions regarding individual certification cases e.g., regarding the applicable scopes.

How long does it take to receive a certificate?

This is highly dependent on what you already have in place and how quickly you can prepare for the audit. Please contact a recognized certification body first and discuss their capacity with them. Once the audit has been conducted, the certification body has 60 days to submit the complete audit package to ISCC.

Additionally, please note that the certificate information is published in a table in the valid certificate section usually a few days after the documentation has been provided to ISCC. The certificate pdf and summary audit report pdf are published once they have undergone an internal review process. Therefore, it may take some time until the pdfs is displayed on our website.

My certificate hasn’t been published on the ISCC website yet, when can I begin selling material?

Your certificate is valid from the date of issue, so it is permitted to handle sustainable material once you receive your certificate from the certification body, even if it hasn’t been published on the ISCC website yet. 

How do I become a recognized certification body for ISCC?

You can find all the requirements and relevant information on the ISCC website, specifically the ISCC System Document 103 “Requirements for Certification Bodies and Auditors”.

The main requirement is the accreditation of the CB against ISO/IEC 17065 or the recognition by a competent national authority (please see chapters 3.2 and 3.3 in the System Document 103 for further specifications). We therefore kindly request you to provide evidence of your recognition or accreditation (e.g. via copy of documents).

If accreditation is not in English, please provide the English translation alongside the original copy.

In addition, please provide evidence of your previous certification experience (e.g. via links to certification examples and recognitions under similar certification systems on your website). Please also provide information on which markets and regions you intend to cover with ISCC certification services as well as the number of auditors and additional staff you intend to assign to ISCC certification services.

If the CB fulfills all necessary requirements, ISCC will subsequently set up a cooperation agreement that has to be signed by both parties, which is supplemented by the ISCC General Terms of Certification (which you can find here).

The ISCC fees for cooperating CBs comprise of an annual license fee as well as a fee per ISCC certificate issued by the CB. Please note that the fees do not include costs for a CB to be recognized by a national authority or accreditation against ISO 17065. Please find the ISCC fee structure (please note only the purple box is relevant for cooperating CBs).

Do you recommend certain CBs for specific scopes?

ISCC does not give recommendations on which certification body to choose. However, you can find a list of all cooperating Certification Bodies here on our website. Most of them are active on a global scale with representatives in many regions of the world. You may also browse through the valid ISCC certificates of companies located in your relevant country by entering it the search function below the table in the row “certificate holder” 

What does ISCC Compliance mean?

Under ISCC the “ISCC Compliant” or “EU RED Compliant” claims can be applied to outgoing deliveries.

The claim “ISCC Compliant” means that the entire upstream supply chain, including the cultivation or collection of the raw material is certified according to ISCC, and the material used in the supply chain consists entirely and solely of ISCC material, at least on a quantity bookkeeping basis. The claim “ISCC Compliant” can be made by ISCC certified operators for outgoing deliveries by adding the statement “ISCC Compliant” to the Sustainability Declaration for outgoing deliveries. The statement “ISCC Compliant” can only be made if the ISCC certified operator has received an equivalent amount of incoming material with the statement “ISCC Compliant” on the Sustainability Declaration. First Gathering Points can only make this statement for deliveries from farms or plantations that comply with the ISCC requirements.

Sustainable material has to be considered “EU RED Compliant” if the ISCC certified operator receives deliveries from suppliers that are certified to any other recognised voluntary certification scheme. Since in this case the upstream supply chain is not ISCC certified, the claim “ISCC Compliant” must not be used.

ISCC certified operators could choose not to include one of the claims above on the Sustainability Declarations. Deliveries of sustainable material without any such statement must be considered “EU RED Compliant” by default.

Which materials can be certified under ISCC?

Depending on the selected certification scheme, meaning ISCC EU, ISCC PLUS or ISCC CORSIA, different materials can be certified. ISCC provides list a of certifiable materials for each certification system in the client section. All materials that can be covered under ISCC EU or ISCC CORSIA can also be covered under ISCC PLUS. 

I would like to certify a material, that is currently not included in the ISCC materials lists. How do I proceed?

The certification body is responsible to discuss with the system user, how their materials are covered on the ISCC material lists. If a material is not yet covered, the certification body can request the material to be added via the ISCC contact form providing the following information: name of material; relevant certification system; categorization as raw material or intermediate/ final product; if applicable, justification for classification as waste/residue e.g. waste code (e.g. based on national waste legislation or European List of Waste, Directive 2008/98/EC) or justification based on the waste decision tree, which is provided in the material lists and if available, the CAS number. A detailed production process chart including all inputs/ outputs and material flows involved must always be provided. For ISCC EU waste/residue material requests, evidence needs to be provided demonstrating that the material is recognized and accepted as a waste or residue in at least one EU Member State within the framework of the RED II and FQD.

Please note that the acceptance of a final product (e.g.biofuel) produced from a raw material which was certified according to the ISCC waste and residue certification process is always the decision of the authorities of the particular EU Member State where the final product comes onto the market (e.g. to fulfil biofuel quota obligations).

Audit and verification


What do I have to keep in mind for my audit?

Please find the ISCC certification process here. The requirements to be fulfilled depend on the scope of the company to be certified. The ISCC audit procedures are scope-specific and provide all relevant requirements. The audit procedures are based on the ISCC System Documents. Further documents are provided in the client section of the ISCC website. It is strongly recommended to plan the audit in time. 

How long do I have to store my records?

Please refer to ISCC System Document 203 – Traceability and Chain of Custody.  

Can I add a warehouse, input material or product to my certification during the certification period?

Yes, this is possible. Please communicate this to your certification body who will then decide if an extension audit is necessary or not. The updated documents will be sent to ISCC and the new certificate uploaded on the ISCC website.

Do I need ISCC certified material before the certification can start?

For an initial audit, you need to prepare templates and other documents (please see check list in client section). The receipt of sustainable material is only possible if the recipient has a valid certificate (ISCC System Document 203, chapter 3.2.2). 

Adding new farmers and materials during the certification period

An additional certification audit is usually not required to add materials or farmers under valid certificates. However, it is always in the responsibility of your certification body to decide if an additional on-site audit is necessary to confirm compliance with ISCC requirements. Please note that we published an ISCC System Update on 30 June 2017 which clarifies the coverage of additional materials and farmers under currently valid certificates. Please take a look a point 3.

Adding additional scopes to an existing certificate

A certificate can cover more than one scope (i.e. the type of certified operation). The Certification Body can adjust the scope of a certificate during the validity period of a certificate. The adjusted certificate has to be provided to ISCC together with the completed audit procedures covering the adjusted scope and any other relevant documents confirming the compliance of the System User with the respective requirements.

Adding additional material to an existing certificate

Additional materials that fall under a scope that is already stated on the certificate can normally be added without an additional on-site audit. For products with individually calculated GHG values, the CB must send ISCC an adjusted audit procedure with the GHG value and the GHG value must have been verified.

However, if a material shall be added for a processing unit, an extension audit may be necessary if the new material requires production facilities that have formerly not been part of the audit. The certification body is responsible to determine if an extension audit is required.

Adding storage facilities to existing certified entities

It is possible to add an additional storage facility under a certificate without the need of an additional audit or a new certificate. The new storage facility must be taken into account for the sampling of storage facilities during your next recertification audit. Please make sure that all relevant documents (contracts, mass balance, etc.) for the new storage are in place. Please inform your certification body about the additional storage facility. Ultimately, it is in the responsibility of the certification body to decide if an additional on-site audit is necessary to confirm compliance with ISCC requirements.


What is a surveillance audit and when must a surveillance audit be conducted?

Mandatory surveillance audits have to be conducted by the certification body six months after the first (initial) certification of any economic operator in a high-risk supply chain. A high risk applies to economic operators that are collecting, processing, storing or trading materials, which may be eligible for extra incentives in individual EU Member States (e.g. double-counting), such as waste and residues or waste and residue-based products. 

For collecting points and traders that are dealing with both waste and residues (e.g. used cooking oil or animal fat) and with virgin vegetable oils (e.g. palm oil, rapeseed oil), a surveillance audit shall be conducted three months after the first (initial) certification (covering the first mass balance period). This surveillance audit shall be conducted in addition to the surveillance audit that has to take place six months after the first certification and shall follow the same risk-based approach. This additional surveillance audit three months after the first certification may be conducted remotely if a risk assessment for the individual system user by the certification body has demonstrated a regular risk. If the risk assessment has shown a risk higher than regular, the surveillance audit shall be conducted on-site. The surveillance audits should mainly focus on traceability requirements, e.g. the verification of delivery documents and mass balances.

Further information about surveillance audits is available in the ISCC document 203: Traceability and Chain of Custody 

Chain of Custody, Traceability and Mass Balance


Which chain of custody options are possible under ISCC?

Under ISCC EU the Chain of Custody options Mass Balance and Physical Segregation are possible. ISCC PLUS also provides the option Controlled Blending. Information about the approaches is available in the documents 203 Traceability and Chain of Custody as well as the ISCC PLUS document 

Where do I find information on the requirements related to mass balance?

Please review the ISCC EU system document 203 and ISCC PLUS system document, chapter 9.4.3.

What kind of information needs to be forwarded on ISCC PLUS sustainability declarations?

The ISCC PLUS System Document, chapter 9.2 provides an overview of the relevant requirements.

Can certified and non-certified materials (e.g. if technically equivalent) be stored together in one silo or do they need to be kept separately?

Under mass balance it is certainly possible to store materials/products together while under the chain of custody option “physical segregation” those would need to be kept separately.

The maximum of one mass balance period is three months. Does this mean that system users have to sell all certified material within this timeframe?

No, the certified material does not need to be sold within three months. Positive credits can be transferred from one mass balance period to the next as long as the certificate is valid. However, it is not allowed to sell more sustainable material than received in stock (go negative) at the end of each mass balance period.

Is it allowed to state percentages on sustainability declarations?

The indication of mt or m3 of the certified material must be indicated on the sustainability declaration. If necessary, it is possible to indicate the quantity and percentage in addition to the metric tons, however it must be very clear how much of the material is ISCC certified.  

Is it possible to combine several raw material categories on one sustainability declaration?

If a certified material/product comprises more than one raw material category, this can be stated on one sustainability declaration. In that case the amounts must be kept separately per raw material category.  

Is it possible to sell material prior to receiving the physical material and to receive/acquire/purchase the credits later on?

The balance of the mass balance must be established at the end of the period (maximum three months). Selling certified material without having the equivalent amount in stocks (to go short) imposes the risk to run into a negative mass balance which is considered as a major non-conformity under ISCC.

How can returns due to e.g. damaged or insufficient quality be handled?

Option 1: The acceptance of the (defective) goods is refused, i.e. they are returned to the supplier. In this case, companies have to provide clear evidence and documentation on the refusal process so that the auditor can transparently verify physical and bookkeeping flows of incoming and outgoing materials.

Option 2: The goods are returned, but the customer issues an SD for them. In this case, the supplier must have booked out the corresponding quantity in the mass balance. The returned goods can then be booked in into the mass balance again (with the new SD).

Does ISCC provide a mass balance template?

As of today, ISCC does not provide such a template. Companies are also free to integrate their mass balance calculations in existing internal software/ ERP systems. In addition, the ISCC PLUS training covers this topic extensively and provides a mass balance calculation as a training element in the group work tasks.

Does the supplier need to provide an LCA analysis and do ISCC PLUS certified companies have to calculate GHG emissions?

ISCC provides a detailed guidance on GHG emission calculation and verification. While for the road transport mandatory, certified operators for industrial applications can include carbon footprint calculations via the voluntary GHG add-on. Please find more information in the ISCC System Document 205 – GHG Emissions and in the ISCC PLUS System Document.

Logos and Claims


Does a company need to be ISCC certified to sell ISCC certified products with an on-product logo?

To sell ISCC certified material with an on-product logo, an ISCC certification or license is mandatory. Please find more information regarding the ISCC licensing scheme here.

Do you have an on-product logo for materials that are linked to both, PCR and bio-attributed ISCC compliant material?

Yes, this possible. Please refer to the document ISCC 208 – ‘Logos and Claims’.


Is it mandatory to use the ISCC logo or to have an ISCC claim on-pack?

It is not mandatory, but much appreciated. Please contact ISCC in advance before using an ISCC logo or ISCC claim. To obtain approval by ISCC and to receive the logo file(s), please fill in the logo application form on the ISCC website.

Does a brand owner need to be certified?

For brand owners who do not alter the certified material, ISCC has developed and implemented an ISCC licensing scheme, which does not require an annual audit. It allows for credible and ISCC specific claims and application of the ISCC logo (on- and off-product). Please find all information and requirements regarding the ISCC licensing scheme here.

Is it mandatory to receive approval for the use of the ISCC off-product logo?

System users can download the ISCC off-product (also called corporate logo) in the ISCC client section. Please note that all the requirements outlined in the ISCC Document 208 – “Logos and Claims” below are relevant. All licensees who would like to use the off-product logo must fill in the logo application form to receive approval for the use of the off-product logo.

Scheme specific questions


Where can I get more information about the ISCC PLUS certification system?

What is the difference between ISCC CORSIA and ISCC CORSIA PLUS?

ISCC CORSIA and ISCC CORSIA PLUS are effectively two versions of the same standard, and in many areas cover the exact same requirements (e.g. for traceability and mass balancing, GHG, auditor requirements, registration and certification process, etc.).

The difference is only in the scope of sustainability requirements for biomass production that the two standard versions cover. ISCC CORSIA covers the currently officially agreed on sustainability criteria under CORSIA. ISCC CORSIA PLUS covers a more comprehensive set of sustainability criteria (i.e. the six ISCC principles), which includes social criteria (e.g. workers rights), best agricultural practices (e.g. regarding pesticide use) and more. This difference is however only relevant for agricultural and forestry feedstocks. For waste and residue feedstocks, there is no difference between ISCC CORSIA and ISCC CORSIA PLUS.

GHG Calculations


Where can up-to-date emissions factors be found?

Please note the hierarchy to be followed regarding sources of emission factors:

1. REDII and relevant related documents, e.g. Commission Implementing Regulation (EU) 2022/996 . Whenever available, the EC standard calculation values shall be used.

2. Alternative values may be used but must be duly justified and flagged in the calculation documentation in order to facilitate verification by auditors. They can be based on Ecoinvent, or individually calculated or measured (e.g. LHV could be measured through laboratory analyses) as long as the methodology for the GHG calculation complies with the methodology set in the RED II and is verifiable during the audit or the supplier of the EF/LHV is ISCC/ISO certified.

3. If not available, other scientifically peer-reviewed literature or official statistical data from government bodies can be used.

All data gathered from databases or literature shall be based on the most recent available sources and shall be updated over time. The source and the date of data collection shall be documented. Emission factors chosen or calculated shall also reflect the specific situation and set-up, e.g. if a process-specific input was produced in Europe then the emission factor for this input shall also reflect the European situation. It is the responsibility of the CB to confirm that alternative sources can be used by the System User.

Can NUTS2 values be used for GHG accounting on cultivation level?

Once the calculation of these values has been scrutinised and approved by the European Commission through an Implementing Act, ISCC system users are allowed to apply these values as an alternative to actual values. Any updates to the NUTS2 values by Member States which have not been included in the reports published before 2015 (pre-ILUC Directive), or the submission of new “NUTS2 equivalent values” for third countries, requires recognition by the EC.

At cultivation level, how should organic fertilizer be accounted for?

Organic fertilizers can apply at two stages in the emission calculation formula

  1. Emissions from the extraction or cultivation of raw materials (eec). As we here refer to total field emissions of all fertilizers (including synthetic, organic and crop residues).
  2. Dependent on the measure and relevant other conditions (e.g.starting date of measure implementation), there could be option to account for emissions savings from soil carbon accumulation via improved agricultural management (esca).

How can different forms of electricity be included in GHG calculations?

If electricity is consumed from the grid, the emission factor of the regional electricity mix (EFelectricity) shall be used. In the case of the EU the most logical choice is the whole EU. If electricity from renewable energies is directly consumed (i.e. not supplied from the grid), an adapted EF for the type of renewable electricity may be used if that plant is not connected to the electricity grid. In the case that an electricity production plant is connected to the grid (e.g. a waste incineration plant), using the average emission value for electricity from that individual electricity production plant in the biofuel production process is permitted if it is guaranteed that there is a direct connection between the biofuel plant and the individual electricity production plant and that it is possible to validate the amount of electricity used with a suitable meter.

Which impact has a material classification as a waste/residue versus a co-product? Why is it important?

The upstream classification of feedstocks as waste/residue or co-product determines the scope of the GHG footprint. For wastes/residues the calculation of GHG emissions starts with the transport from the Point of Origin (PoO) where the waste is generated to the Collecting Point (CP) . For Co-Products calculation of GHG emissions the entire supply chain needs to be included in the GHG calculation, i.e. for a bio-based product emissions from cultivation and potential land use change must be included.

If excess electricity / heat is produced, how can this be integrated into the GHG calculation?

Excess electricity as separate formula element does no longer exist under the REDII. So no direct subtraction from the overall emissions is possible. If excessive heat or electricity is produced and sold externally it should be handled as co-product. Allocation of GHG emissions is possible via the allocation formula described in the System Document 205.

Is there a GHG Calculator accepted by ISCC?

Currently ISCC does not offer templates for the GHG calculations and ISCC is not in the position to officially “recognize” GHG calculators. Their compliance regarding formulas, inputs etc must be verified by the CB. However, we intend to publish an overview template as a helpful guidance soon.

When should default or actual values be used?

Total (TDVs) and disaggregated default values(DDVs) are provided by the RED II in Annex V and Annex VI. These default values reflect biofuel, bioliquid and biomass fuel supply chains and processes, and are conservative estimates. Default values listed in Annex V and Annex VI can be applied only if the process technology, raw material and transport distance (for solid biomass fuels) used for the production of thefuel match the respective scope of the default value. Please note that not with all default values, the minimum GHG savings are achieved.

Therefore, also individually calculated GHG values or “actual values” can/must be calculated based on the RED II methodology (Annex V and Annex VI) and ISCC’s specifications (ISCC EU 205). Individual calculations of GHG emissions must always be conducted at the point in the supply chain where they originate (e.g. emissions from cultivation can only be determined at the farm/plantation or the central office or the FGP of a group of farmers). It is not possible to calculate actual values retrospectively for elements of the upstream supply chain. For the calculation of “actual values” all relevant inputs of an economic operator must be considered.

When using multiple substrates, how should they be accounted for in biomass fuel production? Can DDV be used for some and not for others?

RED II, Annex VI, part c outlines the methodology market operators need to apply in the case of co-digestion of different substrates in a biogas plant for the production of electricity or biomethane. See the system document 205 for more details on the calculation of emissions. A mixture of DDV and actual values is possible when dealing with multiple substrates.

When dealing with multiple batches of the same material with different sustainability characteristics, how should these batches be accounted for?

If an ISCC System User receives different GHG values, the aggregation of GHG values from incoming input materials is only possible if the product identities and GHG values are the same. Either individual values for each incoming batch or the highest GHG value (of the least performing batch) should be used for all incoming batches of the same kind of input material.

Does the calculation period always have to be on a 12-months basis? For example if a plant has scheduled turnaround periods or unscheduled production-stops (force majeure), can certain months only be considered for the calculation?

The calculation period should cover a full twelve-month period and it must be as up to date as possible. In cases of exceptional maintenance measures and unstable production conditions a shorter period (for inputs and respective outputs) may be considered if it better reflects the relevant timeframe. If these activities reflect the normal production process of a year these have to be considered and included in the calculation and twelve months have to be considered.The respective period for data gathering and thus for the calculation of GHG emissions must be transparently displayed in the calculation.

If one entity in the supply chain uses the disaggregated default value DDV for a component of the GHG formula, are all other entities in the supply chain also limited to DDV for that element (i.e etd)?

Yes, this is generally the case. A switch to actual is only possible if complete information regarding this formula element from all entities in the supply chain is available and verifiable. I.e. GHG emission for all transportation steps can be calculated.

How should transport emissions be calculated if transportation distance downstream of the final processing unit is not known?

Should the exact distance for downstream transport and distribution not be known to the final processing unit, two options exist:

  1. Use disaggregated values for transport and distribution as provided in sections D and E of Annex V and Annex VI of the RED II for certain final fuels.
  2. If a final fuel is produced for which no such values are available a conservative approach can be used and the highest value of the most logical choice from these tables can be used (e.g. transport distance to Europe and throughout Europe).

Is it mandatory to pass on GHG values under ISCC PLUS?

No, but if a system user wants to use the GHG add on, all up stream supply chain elements must do so as well.
