How to use EcoBorder

CBAM puts a carbon price on EU imports of aluminium, iron and steel, cement, fertilisers, hydrogen and electricity. The EU importer pays, but they need verified emissions data from the non-EU producer, so the work flows up the supply chain. Pick the path that matches you, or jump to a specific tool.

Quick start by role

I am a non-EU exporter or manufacturer

You make a CBAM-covered good and sell, or want to sell, into the EU.

  1. Check scope: open the CN Code Checker, search your product, pick your country, and see the official 2026 default value.
  2. See the cost of doing nothing: the checker shows the penalty default cost per tonne.
  3. Calculate your real number: use the Emissions Calculator to get your actual SEE, usually lower than defaults.
  4. Model the bill: use the Tax Calculator for your EU-bound tonnage.
  5. Produce buyer-ready figures: use the Communication Builder for the official EU communication.
  6. Save and reuse: sign in, create a project, and store your work.

I am a consultant or adviser

You run CBAM engagements for clients and collect data from their suppliers.

  1. Create a project per client in the Workspace.
  2. Scope exposure with the CN Code Checker and Readiness Check.
  3. Add the client's suppliers and send each a private data-request link.
  4. Turn collected data into SEE and cost figures, and save them to the project.
  5. Deliver the Communication Builder output and use the audit trail as your record.

I was sent a supplier data link

A customer asked you for your material's embedded emissions.

  1. Open the link your customer sent. No account is needed.
  2. Read who is asking and for which material and year.
  3. Enter direct emissions, indirect or electricity emissions, production, and energy source.
  4. Submit. Your data goes only to that customer.

I am an EU importer

You want a quick estimate of your CBAM exposure.

  1. Open the Tax Calculator and add a line per goods type with annual tonnes.
  2. Set the reporting year and certificate price.
  3. Read the net liability and quarterly cost, and export CSV or JSON.
  4. Confirm exact CN codes and country defaults in the CN Code Checker.

EcoBorder produces estimates for planning and education, not legal or financial advice. The authorised CBAM declarant remains legally responsible for official declarations. Data sources are official and dated: country-specific defaults from Implementing Regulation (EU) 2025/2621, the certificate price from the European Commission, and CN codes from the official CBAM template.
