RED III and the Union Database: why a Ukrainian biofuel batch won't enter the EU without ISCC EU

If you ship biodiesel, bioethanol, rapeseed or sunflower to the EU, there's a new market-access condition that most consultants stay quiet about. Without an account in the Union Database, your sustainability certificate gets suspended automatically. And a batch without an active certificate simply doesn't count toward the EU's national targets.

It sounds technical, but in practice it's blunt: no UDB account, no export.

RED III (Directive (EU) 2023/2413) has applied since 20 November 2023, and the main deadline for transposing it into member-state law passed on 20 May 2025. Alongside it, the EU switched on the Union Database, a single registry that every batch of liquid and gaseous biofuel now passes through. Here's the point that matters for a Ukrainian supplier: you can prove sustainability and get into that database only through a recognised certification scheme. For most, that's ISCC EU.

Below we break the RED III → Union Database → ISCC EU chain into steps. What changed, which deadlines have already passed, how the three recognised schemes differ, and what a grain trader or elevator should actually do right now.

RED III, the third edition of the Renewable Energy Directive, raised the bar for the entire biofuel chain. The EU's overall target rose to 42.5% renewable energy by 2030, with an ambition to reach 45%. Biofuels from food and feed crops keep a 7% ceiling, so demand keeps shifting toward certified feedstock with proven origin.

What an exporter feels most is the tighter greenhouse-gas rules. The GHG saving threshold for most new installations went up: the ≥70% benchmark applied through the end of 2025, and from 1 January 2026 new production capacity has to hit ≥80%. Every batch now needs a carbon-footprint calculation from field to plant.

Add stricter traceability on top. RED III explicitly wants sustainability data to land in a central system, not just sit in an auditor's file. That system is the Union Database.

The Union Database (UDB) is the EU's single online registry that tracks every batch of biofuel, bioliquid, biomethane and RFNBO across the whole supply chain. The goal is simple: stop the same batch being counted twice in different countries, and close the loopholes for sustainability-certificate fraud.

The chain used to rely on mass balance and paper certificates from an auditor. Now every transaction has to be mirrored in the database: who produced it, from which feedstock, where, and with what GHG figures. The UDB application went live on 15 January 2024, liquid fuels came online first, and the deadline for gaseous fuels to go into the system was 21 November 2024.

For a Ukrainian trader this means one plain thing. Your European buyer can't count your batch toward their RED targets until it's registered in the UDB with correct data. And you can only enter that data through certified links in the chain.

Here's the core of the whole story, and it's something Ukraine's information space barely spells out.

The Union Database doesn't collect data on its own. It leans on what recognised certification schemes already verify: the unique batch identifier, chain-of-custody records, the emissions calculation and mass balance. Put simply, ISCC EU acts as the practical gateway to the UDB. The certificate gives you the valid data without which a database entry just isn't possible.

The flip side of that link is harsh. If a certified operator has no active UDB account, or doesn't enter transactions, the scheme can suspend the certificate. And a suspended certificate isn't a formality: the batch loses its sustainable status, the European counterparty can't count it, and you either take a discount or drop out of the tender.

The audit is different too. The auditor now checks not only your procedures but how you actually use the UDB, and reconciles mass balance against the transactions in the database. A gap between your paperwork and the database has become its own ground for a non-conformity.

All three schemes are recognised by the European Commission and deliver the same legal result: proof of sustainability under RED. The difference is coverage, geography and how convenient each one is for a given type of business. Honestly, for most Ukrainian exporters the choice comes down to ISCC EU, but it's worth knowing the alternatives.

Here's a short comparison against typical Ukrainian profiles. Details on each scheme live on the ISCC, REDcert and 2BSvs pages.

Some deadlines are already behind us, some are running right now. Here are the key dates in one table, so you can see where you're falling behind.

The theory is clear, so let's get to action. Here's a concrete order for a trader, elevator or producer that has no certificate yet, or has one but with no UDB set up.

1. Pin down your role in the chain. First Gathering Point, trader or processor, because that drives the set of requirements and the type of audit.
2. Set up mass balance. Sustainable and non-sustainable batches on the elevator must be tracked separately and documented, or the auditor won't close Stage 2.
3. Open and activate a Union Database account. Assign someone who actually enters transactions, not a "sometime later" placeholder.
4. Collect farmer onboarding data. This is where most of the pain lives: you need field geo-coordinates, sustainability declarations, and data for the GHG calculation. Start it before the season, not during it.
5. Order a diagnostic audit to fix your baseline and see the gap to the scheme's requirements.

One honest warning. The tightest bottleneck isn't the certificate itself, it's onboarding your feedstock suppliers. If you have hundreds of farmers with no geo-data, you won't pull it all together a week before the audit. So build the timeline from data collection, not from the audit date.

Ekontrol prepares Ukrainian companies for sustainability-scheme certification as a project with clear phases, not as a one-off consultation.

• Diagnostic audit under ISCC EU, REDcert or 2BSvs: a gap analysis of the chain from field to shipment.
• System implementation for sustainability: mass balance, traceability procedures, and setting up work with the Union Database.
• Certification audit support at Stage 1 and Stage 2 with an accredited body.
• Annual support to keep the certificate, handle surveillance audits and maintain correct UDB transactions.
