The UDB is a database pursuant to Article 28 (2) and (4) of Directive (EU) 2018/2001 (RED II), Article 18 of Implementing Regulation (EU) 2022/996 and Article 31a of Directive (EU) 2023/2413, which aims to improve the traceability of gaseous and liquid fuels. It collects sustainability and transaction data along the supply chain. The aim is to avoid double counting and to minimize the risk of irregularities and fraud.

The UDB was introduced to ensure compliance with the requirements of the Renewable Energy Directive (RED II) and related legal texts, to prevent fraud, double counting and to prove the greenhouse gas reduction of fuels.

All actors in the supply chain, including raw material suppliers, producers of renewable liquid and gaseous fuels, who are linked with the interconnected gas grid, and recycled carbon fuels, suppliers and end-users of sustainability certificates, are required to use the UDB.

The UDB collects and tracks transaction data along the entire supply chain from liquid or gaseous renewable fuel or recycled carbon fuel to ensure transparency and traceability.

The UDB uses modern security protocols and encryption techniques to protect the integrity and confidentiality of the data. An important part of this is a personalized, 2-factor authenticated EU Login account for secure access to the UDB. Further information can be found in the Privacy Statement of the UDB.

For data protection reasons, no sensitive data should be entered by the company in the Acceptance-Version.

The UDB offers interfaces to other systems to enable seamless integration. The REDcert-database transmits all relevant information (required by the EC) to the UDB via such an interface. During this, you have also been created a company account in the UDB with a valid certificate.

Registration in the UDB should be done via the link in the invitation email or in the event that the link was not correctly triggered, the first contact person of your company can get direct access with its EU Login Mail to the UDB. Please do not register separately or independently, otherwise there will be no assignment to REDcert in the system (and no valid certificate can be assigned to you). Sometimes the UDB does not trigger the invitation link and you do not receive an email. This is not a problem, as your email address remains linked to your company account and when you log in to the UDB (e.g. via direct dial-in), the verified EU Login account associated with your email address is automatically recognized and you are finally directed to your company account. In other words, the UDB user interface uses your e-mail address to determine whether your EU Login account is complete and has been assigned to your company. If you have already registered independently in the UDB, please send an email with a screenshot of your UDB profile and your REDcert ID to udb@redcert.de.

Enter your login data [EU-Login] carefully.

Make sure that your user name and password are correct and do not contain any typing errors. Here you will find detailed step-by-step instructions for accessing the UDB.

In order to ensure security and privacy when logging in and registering in the UDB, we strongly recommend that you follow the following procedure:

• Be sure to use a personal email address for your personal EU Login account.
• Avoid using generic email addresses such as info@company.com or office@company.com.
• Ideally, you should use your business, personalized email address (e.g. firstname.lastname@company.com). 
• If you don't have a personalized business email, you can also use a private email address that can be uniquely assigned to you.

These measures serve to

... ensure the allocation of the EU account to a specific person.

... Prevent unauthorized access to sensitive company data.

... to ensure the traceability of actions in the UDB.

... Comply with EU data protection directives and security standards

Please note that using a personal email address is an important step in protecting the security of your company and your data in the UDB.

The invitation link will be sent to the email address of the first contact person registered for your company in the REDcert database. Please note that these emails will come from the domain @ec.europa.eu. If the link was not triggered correctly, the first contact person in your company can still access your existing UDB account with the EU login email, as the link between the email address and the UDB account has been saved. The UDB user interface uses your email address to determine whether your EU Login account is complete and has been assigned to your company.

Check your spam folder and whitelist the sender address (domain @ec.europa.eu). It is possible that the link was not triggered correctly. Your company's 1st contact person can still access your existing UDB account with the EU login email, as the link between the email address and the UDB account has been saved. Since your company information in the UDB comes directly from the REDcert database, you should make sure that your data in the REDcert database is up to date. For security reasons, the invitation email will only be sent to the first contact person who is stored in the REDcert database. Therefore, the EU Login account must also match this email. You can subsequently distribute further accesses within the company according to the “snowball” system. If you still haven't received a link, send an email to udb@redcert.de. with the subject "Invitation link" and indicate your REDcert ID.

The initial stock is your existing stock on a selected key date. You must enter this in the UDB if you want to start using the system. If you do not have any starting stock due to a trader activity or comparable activity, a zero would have to be entered here or, if necessary, no notification would be required. This function seems to be linked with the certified scope.

 Please note that the following conditions must be met before starting in the UDB:

1. Correct company profile in the UDB
2. Unique company identifier (NTR ID)
3. Valid certificate has been transferred from the REDcert database
4. Start date and duration of the mass balance period is specified
5. In preparation for transactions, the buyer contacts (applies to everyone) and the sourcing contacts for first gathering points and collectors of waste and residues need to be created
6. It is clear for your company whether you want to use transactions manually or via eDeliver via an interface to the UDB.

Sourcing contacts are farms or collectors of waste and residues from which you receive biomass. Only first gathering points and collectors have to create them in order to book goods in the UDB.

Use the Manage sourcing contacts feature in the UDB to add your suppliers. You can also use a bulk upload template for multiple entries. Everything else is explained in the step-by-step instructions. You can either add individual companies manually or upload several companies via an Excel spreadsheet

For example, you will need the name, address and country affiliation. In the collective Excel template, all columns must be filled in with *. A clear identification of the farms, such as VAT ID, tax ID, IACS number (the term varies depending on the federal state: also known as farm number or registration number, through which the agricultural application is submitted), is not mandatory. The information on the sourcing contacts can be added manually or via collective excel file.

To do this, use the step-by-step instructions. This describes how to log into the UDB account, download the template, fill out the spreadsheet of buyers, and upload it via a collective excel file.

You will need the unique company identifier (NTR ID or VAT ID) and, if applicable, the full company name of the buyer. This information can be added via collective excel file. Please communicate with your buyers and make sure that the UDB accounts have been created correctly.

Transactions can be stored in the UDB manually, via bulk upload or via eDelivery. Make sure that the company's unique company identification (usually VAT ID) is correct and that your buyers have been created beforehand.

Transactions should be recorded in the UDB in a timely manner. There is currently no exact definition of this. However, transactions should only be entered in the UDB once invoicing has been carried out in order to avoid unnecessary correction postings.

Each transaction from a specific location should be linked to the respective valid certificate. The certificates are automatically stored via the interface of the REDcert database.

Yes, multiple certificates (from the same or from different voluntary schemes) can be linked to the same organization.
